AIDAsol shore power Rostock-Warnemfcnde delivers cold ironing for cruise ships, up to 20 MVA at berths P7 and P8, cutting port emissions during berthing and advancing AIDA's green cruising strategy across European ports.

 

Key Points

Rostock-Warnemfcnde shore power supplies two cruise ships up to 20 MVA, enabling cold ironing and cutting emissions.

✅ Up to 20 MVA; powers two cruise ships at berths P7 and P8

✅ Enables cold ironing for AIDA fleet to reduce berth emissions

✅ Part of AIDA green cruising with fuel cells and batteries

 

In a ceremony held in Rostock-Warnemünde yesterday during Germany’s 12th National Maritime Conference, the 2,174-passenger cruise ship AIDAsol inaugurated Europe’s largest shore power plants for ships.

The power plant has been established under a joint agreement between AIDA Cruises, a unit of Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the state government of Mecklenburg-Western Pomerania, the city of Rostock and the Port of Rostock.

“With our green cruising strategy, we have been investing in a sustainable cruise market for many years,” said AIDA Cruises President Felix Eichhorn. “The shore power plant in Rostock-Warnemünde is another important step — after the facility in Hamburg — on our way to an emission-neutral cruise that we want to achieve with our fleet. I would like to thank the state government of Mecklenburg-Western Pomerania and all partners involved for the good and trusting cooperation. Together, we are sending out an important signal, not just in Germany, but throughout Europe.”

CAN POWER TWO CRUISE SHIPS AT A TIME
The shore power plant, which was completed in summer 2020, is currently the largest in Europe and aligns with port electrification efforts such as the all-electric berth at London Gateway in the UK. With an output of up to 20 megavolt amperes (MVA), two cruise ships can be supplied with electricity at the same time at berths P7 and P8 in Warnemünde.

In regular passenger operation AIDAsol needs up to 4.5 megawatts per hour (MWh) of electricity.

The use of shore power to supply ships with energy is a decisive step in AIDA Cruises’ plans to reduce local emissions to zero during berthing, complementing recent progress with electric ships on the B.C. coast, as a cruise ship typically stays in port around 40% of its operating time.

As early as 2004, when the order for the construction of AIDAdiva was placed, and for all other ships put into service in subsequent years, the company has considered the use of shore power as an option for environmentally friendly ship operation.

Since 2017, AIDA Cruises has been using Europe’s first shore power plant in Hamburg-Altona, where AIDAsol is in regular operation, while operators like BC Ferries add hybrid ferries to expand low-emission service in Canada. Currently, 10 ships in the AIDA fleet can either use shore power where available or are technically prepared for it.

The aim is to convert all ships built from 2000 onwards, supporting future solutions like offshore charging with wind power.

With AIDA Cruises starting a cruise season from Kiel, Germany, on May 22, AIDAsol will also be the first cruise ship to complete the final tests on a newly built shore power plant there, as innovations such as Berlin’s electric flying ferry highlight the broader shift toward electrified waterways. Construction of that plant is the result of a joint initiative by the state government of Schleswig-Holstein, the city and the port of Kiel and AIDA Cruises. AIDAsol is scheduled to arrive in Kiel on the afternoon of May 13.

As part of its green cruising strategy, AIDA Cruises has been investing in a sustainable cruise operation for many years, paralleling urban shifts toward zero-emission bus fleets in Berlin. Other steps on the path to the zero emission ship of the future are already in preparation. This year, AIDAnova will receive the first fuel cell to be used on an ocean-going cruise ship. In 2022, the largest battery storage system to date in cruise shipping will go into operation on board an AIDA ship, similar to advances in battery-electric ferries in the U.S. In addition, the company is already addressing the question of how renewable fuels can be used on board cruise ships in the future.

Charting a path to net zero electricity emissions by the middle of the century

Clean Energy Standard charts a federal path to decarbonize the power sector, scaling renewables, wind, solar, nuclear, and carbon capture to slash emissions, create green jobs, and reach net-zero targets amid the climate crisis.

 

Key Points

A federal policy to expand clean power and cut emissions with renewables, nuclear, and carbon capture toward net-zero.

✅ Mandates annual increases in clean electricity supply

✅ Includes renewables, nuclear, hydro, and carbon capture

✅ Targets rapid emissions cuts and net-zero by mid-century

 

The world has been put on notice. Last year, both the UN Intergovernmental Panel on Climate Change and the U.S. National Climate Assessment warned that we need to slash greenhouse gas emissions to avoid disastrous impacts of global warming. Their direct language forecasting devastating effects on our health, economics, environment, and ways of life has made even more urgent the responsibility we all have to act boldly to combat the climate crisis.

This week, we’re adding one important tool for addressing the climate crisis to the national conversation.

Together, we’re taking that bold action. The Climate reports made clear that to limit the global temperature rise and stave off devastating impacts to our climate—human-caused CO2 emissions must fall rapidly by 2030 and that we, as a global community, underscored at the Katowice climate talks, must reach net-zero emissions by the middle of the century. The Clean Energy Standard is federal legislation that offers a pathway toward decarbonizing our power sector and helping our nation accomplish a goal of net-zero emissions by the 2050s.

Under this plan, any company selling retail electricity will have a mandate to increase the amount of clean energy provided to its customers. It will incentivize clean electricity investment to put the U.S. on a sustainable path.

To deal most effectively with a crisis, all tools must be on the table. Our plan focuses solely on emissions, and there is a place for all technologies that can put us on the path to net zero. That will mean drastic increases in wind and solar energy for sure, as states like California pursue a 100% carbon-free electricity mandate to accelerate deployment, but nuclear power, hydro power, and fossil fuels with carbon capture and storage all have important roles to play.

We’re doing this because the science is clear – tackling our climate crisis requires serious and rapid action to control greenhouse gas emissions, and the push for decarbonization is irreversible according to many. Inaction on the climate crisis puts our families at risk, and we’re not wasting any time. This is also an opportunity to create good-paying green jobs that can last generations and uplift the middle class.

We are doing this for the environment, but also for jobs and economic competitiveness. The green economy is the future and we’re ready to see it grow, with states like New York advancing a Green New Deal that drives innovation. The United States can lead, or we can follow, and we want our nation to lead.

And, because as a New Mexican and a Minnesotan, we know that the impacts of climate change go far beyond the headlines and political discourse. It means devastation within tamarack forests and an increase in deadly fires. It means hotter summers and shorter winters with extreme temperature swings throughout the year. It means devastating flash floods with increasingly intense rain. It’s impacting our pocketbooks when farmers and small businesses who work the land in rural communities are unable to make ends meet.

States across the country are already acting to combat the climate crisis – including Minnesota's 2050 carbon-free electricity plan and New Mexico. But in order to truly address climate change, we have to be in this together as Americans. If the problem is far-reaching, our solutions must be equally as holistic.

It's why we've worked with green groups and activists, unions, and communities across the country - from urban to rural - to create a solution that understands the different starting points communities face in reaching net zero emissions, but doesn't shrink from the absolute need to reach that standard.

There is not one solution to climate change – it will take a collective group of individuals prepared to boldly act. And we are ready to take on that fight.

In Congress, we have formed the House Select Committee on the Climate Crisis and the Senate Democrats’ Special Committee on the Climate Crisis to hear from everyday Americans how climate change is affecting them – and how we can come together to find solutions that build on the historic climate deal passed this year. We have heard the stories of young people worried about their futures. And we realize there is a sense of urgency to act.

Over the coming weeks and months, we will be building support from communities across the country to make this plan a reality. We will continue working with stakeholders to ensure every voice is heard. Most importantly, we will continue listening to you and your communities.

Canada's nationwide climate success — electricity

Canada Clean Electricity leads decarbonization, slashing power-sector emissions through coal phase-out, renewables like hydro, wind, and solar, and nuclear. Provinces cut carbon intensity, enabling electrification of transport and buildings toward net-zero goals.

 

Key Points

Canada Clean Electricity is the shift to low-emission power by phasing out coal and scaling renewables and nuclear.

✅ 38% cut in electricity emissions since 2005; 84% fossil-free power.

✅ Provinces lead coal phase-out; carbon intensity plummets.

✅ Enables EVs, heat pumps, and building electrification.

 

It's our country’s one big climate success so far.

"All across Canada, electricity generation has been getting much cleaner. It's our country’s one big climate success so far,"

To illustrate how quickly electric power is being cleaned up, what's still left to do, and the benefits it brings, I've dug into Canada's latest emissions inventory and created a series of charts below.

 

The sector that could

Climate pollution by Canadian economic sector, 2005 to 2017My first chart shows how Canada's economic sectors have changed their climate pollution since 2005.

While most sectors have increased their pollution or made little progress in the climate fight, our electricity sector has shined.

As the green line shows, Canadians have eliminated an impressive 38 per cent of the climate pollution from electricity generation in just over a decade.

To put these shifts into context, I've shown Canada's 2020 climate target on the chart as a gray star. This target was set by the Harper government as part of the global Copenhagen Accord. Specifically, Canada pledged to cut our climate pollution 17 per cent below 2005 levels under evolving Canadian climate policy frameworks of the time.

As you can see, the electricity sector is the only one to have done that so far. And it didn’t just hit the target — it cut more than twice as much.

Change in Canada's electricity generation, 2005 to 2017My next chart shows how the electricity mix changed. The big climate pollution cuts came primarily from reductions in coal burning, highlighting the broader implications of decarbonizing Canada's electricity grid for fuel choices.

The decline in coal-fired power was replaced (and then some) by increases in renewable electricity and other zero-emissions sources — hydro, wind, solar and nuclear.

As a result, Canada's overall electricity generation is now 84 per cent fossil free.

 

Every province making progress

A primary reason why electricity emissions fell so quickly is because every province worked to clean up Canada's electricity together.

Change in Canadian provincial electricity carbon intensity, 2005 to 2017

My next chart illustrates this rare example of Canada-wide climate progress. It shows how quickly the carbon-intensity of electricity generation has declined in different provinces.

(Note: carbon-intensity is the amount of climate pollution emitted per kilowatt-hour of electricity generated: gCO2e/kWh).

Ontario clearly led the way with an amazing 92 per cent reduction in climate pollution per kWh in just twelve years. Most of that came from ending the burning of coal in their power plants. But a big chunk also came from cutting in half the amount of natural gas they burn for electricity.

Manitoba, Quebec and B.C. also made huge improvements.

Even Alberta and Saskatchewan, which were otherwise busy increasing their overall climate pollution, made progress in cleaning up their electricity.

These real-world examples show that rapid and substantial climate progress can happen in Canada when a broad-spectrum of political parties and provinces decide to act.

Most Canadians now have superclean electricity

As a result of this rapid cleanup, most Canadians now have access to superclean energy.

Canadian provincial electricity carbon intensity in 2017

 

Who has it? And how clean is it?

The biggest climate story here is the superclean electricity generated by the four provinces shown on the left side — Quebec, Manitoba, B.C. and Ontario. Eighty per cent of Canadians live in these provinces and have access to this climate-safe energy source.

Those living in Alberta and Saskatchewan, however, still have fairly dirty electricity — as shown in orange on the right — and options like bridging the electricity gap between Alberta and B.C. could accelerate progress in the West.

A lot more cleanup must happen here before the families and businesses in these provinces have a climate-safe energy supply.

 

What's left to do?

Canada's electricity sector has two big climate tasks remaining: finishing the cleanup of existing power and generating even more clean energy to replace fossil fuels like the gasoline and natural gas used by vehicles, factories and other buildings.

 

Finishing the clean up

Climate pollution from Canadian provincial electricity 2005 and 2017

As we saw above, more than a third of the climate pollution from electricity has already been eliminated. That leaves nearly two-thirds still to clean up.

Back in 2005, Canada's total electricity emissions were 125 million tonnes (MtCO2).

Over the next twelve years, emissions fell by more than a third (-46 MtCO2). Ontario did most of the work by cutting 33 MtCO2. Alberta, New Brunswick and Nova Scotia made the next biggest cuts of around 4 MtCO2 each.

Now nearly eighty million tonnes of climate pollution remain.

As you can see, nearly all of that now comes from Alberta and Saskatchewan. As a result, continuing Canada's climate progress in the power sector now requires big cuts in the electricity emissions from these two provinces.

 

Generating more clean electricity

The second big climate task remaining for Canada's electricity is to generate more clean electricity to replace the fossil fuels burned in other sectors. My next chart lets you see how big a task this is.

 

Clean electricity generation by Canadian province, 2017

It shows how much climate-safe electricity is currently generated in major provinces. This includes zero-emissions renewables (blue bars) and nuclear power (pale blue).

Quebec tops the list with 191 terawatt-hours (TWh) per year. While impressive, it only accounts for around half of the energy Quebecers use. The other half still comes from climate-damaging fossil fuels and to replace those, Quebec will need to build out more clean energy.

The good news here is that electricity is more efficient for most tasks, so fossil fuels can be replaced with significantly less electric energy. In addition, other efficiency and reduction measures can further reduce the amount of new electricity needed.

Newfoundland and Labrador is in the best situation. They are the only province that already generates more climate-safe electricity than they would need to replace all the fossil fuels they burn. They currently export most of that clean electricity.

At the other extreme are Alberta and Saskatchewan. These provinces currently produce very little climate-safe energy. For example, Alberta's 7 TWh of climate-safe electricity is only enough to cover 1 per cent of the energy used in the province.

All told, Canadians currently burn fossil fuels for three-quarters of the energy we use. To preserve a safe-and-sane climate, most provinces will soon need lots more clean electricity in the race to net-zero to replace the fossil fuels we burn.

How soon will they need it?

According to the most recent report from the International Panel on Climate Change (IPCC), avoiding a full-blown climate crisis will require humanity to cut emissions by 45 per cent over the next decade.

 

Using electricity to clean up other sectors

Finally, let's look at how electricity can help clean up two of Canada’s other high-emission sectors — transportation and buildings.

 

Cleaning up transportation

Transportation is now the second biggest climate polluting sector in Canada (after the oil and gas industry). So, it’s a top priority to reduce the amount of gasoline we use.

Canadian provincial electricity carbon intensity in 2017, plus gasoline equivalent

Switching to electric vehicles (EVs) can reduce transportation emissions by a little, or a lot. It depends on how clean the electricity supply is.

To make it easy to compare gasoline to each province's electricity I've added a new grey-striped zone at the top of the carbon-intensity chart.

This new zone shows that burning gasoline in cars and trucks has a carbon-intensity equivalent to more than 1,000 gCO2e/kWh. (If you are interested in the details of this and other data points, see the geeky endnotes.)

The good news is that every province's electricity is now much cleaner than gasoline as a transportation fuel.

In fact, most Canadians have electricity that is at least 95 per cent less climate polluting than gasoline. Electrifying vehicles in these provinces virtually eliminates those transportation emissions.

Even in Alberta, which has the dirtiest electricity, it is 20 per cent cleaner than gasoline. That's a help, for sure. But it also means that Albertans must electrify many more vehicles to achieve the same emissions reductions as regions with cleaner electricity.

In addition to reducing climate pollution, switching transportation to electricity brings other big benefits:

It reduces air pollution in cities — a major health hazard.

It cuts the energy required for transportation by 75 per cent — because electric motors are so much more efficient.

It reduces fuel costs up to 80 per cent — saving tens of thousands of dollars.

And for gasoline-importing provinces, using local electricity keeps billions of fuel dollars inside their provincial economy.

As an extra bonus, it makes it hard for companies to manipulate the price or for outsiders to "turn off the taps.”

 

Cleaning up buildings

Canada's third biggest source of climate pollution is the buildings sector.

Burning natural gas for heating is the primary cause. So, reducing the amount of fossil gas burned in buildings is another top climate requirement.

Canadian provincial electricity carbon intensity in 2017, plus gasoline and nat gas heating equivalent

Heating with electricity is a common alternative. However, it's not always less climate polluting. It depends on how clean the electricity is.

To compare these two heating sources, look at the lower grey-striped zone I've added to the chart.

It shows that heating with natural gas has a carbon-intensity of 200 to 300 gCO2 per kWh of heat delivered. High-efficiency gas furnaces are at the lower end of this range.

As you can see, for most Canadians, electric heat is now the much cleaner choice — nearly eliminating emissions from buildings. But in Alberta and Saskatchewan, electricity is still too dirty to replace natural gas heat.

The climate benefits of electric heat can be improved further by using the newer high-efficiency air-source heat pump technologies like mini-splits. These can heat using one half to one third of the electricity of standard electric baseboard heaters. That means it is possible to use electricity that is a bit dirtier than natural gas and still deliver cleaner heating. As a bonus, heat pumps can free up a lot of existing electricity supply when used to replace existing electric baseboards.

 

Electrify everything

You’ve probably heard people say that to fight climate breakdown, we need to “electrify everything.” Of course, the electricity itself needs to be clean and what we’ve seen is that Canada is making important progress on that front. The electricity industry, and the politicians that prodded them, all deserve kudos for slashing emissions at more than twice the rate of any other sector.

We still need to finish the cleanup job, but we also need to turn our sights to the even bigger task ahead: requiring that everything fossil fuelled — every building, every factory, every vehicle — switches to clean Canadian power.

California Halts Energy Rebate Program Amid Trump Freeze

California energy rebate freeze disrupts heat pump incentives, HVAC upgrades, and climate funding, as federal uncertainty stalls Inflation Reduction Act support, delaying home electrification, energy efficiency gains, and greenhouse gas emissions reductions statewide.

 

Key Points

A statewide pause on $290M incentives for heat pumps and HVAC upgrades due to federal climate funding uncertainty.

✅ $290M program paused amid federal funding freeze

✅ Heat pump, HVAC, electrification upgrades delayed

✅ Previously approved rebates honored; new apps halted

 

California’s push for a more energy-efficient future has hit a significant roadblock as the state pauses a $290 million rebate program aimed at helping homeowners replace inefficient heating and cooling systems with more energy-efficient alternatives. The California Energy Commission announced the suspension of the program, citing uncertainty stemming from President Donald Trump’s decision to freeze funding for various climate-related initiatives.

The Halted Program

The energy rebate program, which utilizes federal funding to encourage the use of energy-efficient appliances such as heat pumps, was a crucial part of California’s efforts to reduce energy consumption and greenhouse gas emissions. By providing financial incentives for homeowners to upgrade to more efficient heating and cooling systems, the program aimed to make green energy solutions more accessible and affordable to residents. The rebate program had been popular, with many homeowners eager to participate in the initiative to lower their energy costs and improve the sustainability of their homes.

However, due to the uncertainty surrounding federal funding, the California Energy Commission announced on Monday that it would no longer be accepting new applications for the program. The agency did clarify that it would continue to honor rebates for applications that had already been approved. The pause will remain in effect until the Trump administration provides more clarity regarding the program's future funding.

The Trump Administration’s Role

This move highlights a broader issue regarding access to federal funding for state-level energy programs. The Trump administration’s decision to freeze funding for climate-related initiatives has left many states in limbo, as previously approved federal money has not been distributed as expected. Despite federal court rulings directing the Trump administration to restore these funds, states like California are still struggling to navigate the uncertainty of climate-related financial support from the federal government.

California’s decision to pause the rebate program comes after similar actions by other states. Arizona paused a similar program just a week prior, and Rhode Island had already paused new applications earlier this year. These states are all recipients of funding from a larger $4.3 billion initiative under the Inflation Reduction Act, which is designed to help homeowners purchase energy-efficient appliances like heat pumps, water heaters, and electric cooktops.

Impact of the Freeze

The pause of California's rebate program has serious implications for both consumers and the state’s energy goals. For residents, the halt means delays in the ability to upgrade to more energy-efficient home systems, which could lead to higher energy costs in the short term, a concern amid soaring electricity prices across the state.

The $290 million program was a significant step in encouraging homeowners to invest in energy efficiency, and its suspension leaves a gap in the availability of resources for those who were hoping to make energy-saving upgrades. Many of these upgrades are not just beneficial to homeowners, but they also contribute to the state’s overall energy efficiency goals, helping to reduce reliance on non-renewable energy sources, even as California's dependence on fossil fuels persists, and decrease greenhouse gas emissions.

Federal and State Tensions

The freeze in funding is just one of many points of tension between the Trump administration and states like California, which have pursued aggressive environmental policies aimed at reducing emissions and combating climate change. California has often found itself at odds with the federal government on environmental issues, especially under the leadership of President Trump. The state’s ambitious environmental policies have sometimes clashed with the federal government's approach, including efforts to wind down its fossil fuel industry in line with climate goals.

In this case, the freeze on climate-related funding appears to be part of a broader strategy by the Trump administration to limit federal spending on environmental programs, and as regulators weigh whether the state may need more power plants, planning remains complex. While the freeze impacts states that are working to transition to clean energy, critics argue that such moves undermine efforts to tackle climate change and could slow down progress toward a greener future.

The Path Forward

For California, the next steps will depend heavily on the actions of the federal government. While the state can continue to push for climate funding in the courts, the lack of clarity around the release of federal funds creates uncertainty for state programs that rely on these resources. As California continues to navigate this funding freeze, it will need to explore alternative solutions to keep its energy efficiency programs on track, such as efforts to revamp electricity rates to clean the grid, even in the face of federal challenges.

In the meantime, California residents and homeowners who were hoping to take advantage of the rebate program may have to wait until further clarification from the federal government is provided, even as officials warn of a looming electricity shortage in coming years. Whether the program can be restored or expanded in the future remains to be seen, but for now, the pause serves as a reminder of the ongoing struggles that states face when dealing with shifting federal priorities.

As the issue unfolds, other states facing similar challenges may take cues from California’s actions, and with California exporting energy policies to Western states, broader conversations about how federal and state governments can collaborate to ensure that energy efficiency initiatives and climate goals are not sidelined due to political or budgetary differences.

California’s decision to pause its $290 million energy rebate program is a significant development in the ongoing struggle between state and federal governments over climate-related funding. The uncertainty created by the Trump administration’s freeze on energy efficiency programs has led to disruptions in state-level efforts to promote sustainability and reduce emissions. As the situation continues to evolve, both California and other states will need to consider how to move forward without relying on federal funding that may or may not be available in the future.

B.C. ordered to pay $10M for denying Squamish power project

Greengen Misfeasance Ruling details a B.C. Supreme Court decision awarding $10.125 million over wrongfully denied Crown land and water licence permits for a Fries Creek run-of-river hydro project under a BC Hydro contract.

 

Key Points

A B.C. Supreme Court ruling awarding $10.125M for wrongful denial of Crown land and water licences on Greengen's project.

✅ $10.125M damages for misfeasance in public office

✅ Denial of Crown land tenure and water licence permits

✅ Tied to Fries Creek run-of-river and BC Hydro EPA

 

A B.C. Supreme Court judge has ordered the provincial government to pay $10.125 million after it denied permits to a company that wanted to build a run-of-the river independent power project near Squamish.

In his Oct. 10 decision, Justice Kevin Loo said the plaintiff, Greengen Holdings Ltd., “lost an opportunity to achieve a completed and profitable hydro-electric project” after government representatives wrongfully exercised their legal authority, a transgression described in the ruling as “misfeasance,” with separate concerns reflected in an Ontario market gaming investigation reported elsewhere.

Between 2003 and 2009, the company sought to develop a hydro-electric project on and around Fries Creek, which sits opposite the Brackendale neighbourhood on the other side of the Squamish River. To do so, Greengen Holdings Ltd. required a water licence from the Minister of the Environment and tenure over Crown land from the Minister of Agriculture.

After a lengthy process involving extensive communications between Greengen and various provincial and other ministries and regulatory agencies, the permits were denied, according to Loo. Both decisions cited impacts on Squamish Nation cultural sites that could not be mitigated.

Elsewhere, an Indigenous-owned project in James Bay proceeded despite repeated denials, underscoring varied approaches to community participation.

40-year electricity plan relied on Crown land
The case dates back to December 2005, when BC Hydro issued an open call for power with Greengen. The company submitted a tender several months later.

On July 26, 2006, BC Hydro awarded Greengen an energy purchase agreement, amid evolving LNG electricity demand across the province, under which Greengen would be entitled to supply electricity at a fixed price for 40 years.

Unlike conventional hydroelectric projects, such as new BC generating stations recently commissioned, which store large volumes of water in reservoirs, and in so doing flood large tracts of land, a run of the river project often requires little or no water storage. Instead, from a high elevation, they divert water from a stream or river channel.

Water is then sent into a pressured pipeline known as a penstock, and later passed through turbines to generate electricity, Loo explained, as utilities pursue long-term plans like the Hydro-Québec strategy to reduce fossil fuel reliance. The system returns water to the original stream or river, or into another body of water. 

The project called for most of that infrastructure to be built on Crown land, according to the ruling.

All sides seemed to support the project
In early 2005, company principle Terry Sonderhoff discussed the Fries Creek project in a preliminary meeting with Squamish Nation Chief Ian Campbell.

“Mr. Sonderhoff testified that Chief Campbell seemed supportive of the project at the time,” Loo said.

New England's solar growth is creating tension over who pays for grid upgrades

New England Solar Interconnection Costs highlight distributed generation strains, transmission charges, distribution upgrades, and DAF fees as National Grid maps hosting capacity, driving queue delays and FERC disputes in Rhode Island and Massachusetts.

 

Key Points

Rising upfront grid upgrade and DAF charges for distributed solar in RI and MA, including some transmission costs.

✅ Upfront grid upgrades shifted to project developers

✅ DAF and transmission charges increase per MW costs

✅ Queue delays tied to hosting capacity and cluster studies

 

Solar developers in Rhode Island and Massachusetts say soaring charges to interconnect with the electric grid are threatening the viability of projects. 

As more large-scale solar projects line up for connections, developers are being charged upfront for the full cost of the infrastructure upgrades required, a long-common practice that they say is now becoming untenable amid debates over a new solar customer charge in Nova Scotia. 

“It is a huge issue that reflects an under-invested grid that is not ready for the volume of distributed generation that we’re seeing and that we need, particularly solar,” said Jeremy McDiarmid, vice president for policy and government affairs at the Northeast Clean Energy Council, a nonprofit business organization. 

Connecting solar and wind systems to the grid often requires upgrades to the distribution system to prevent problems, such as voltage fluctuations and reliability risks highlighted by Australian distributors in their networks. Costs can vary considerably from place to place, depending on the amount of distributed generation coming online and the level of capacity planning by regulators, said David Feldman, a senior financial analyst at the National Renewable Energy Laboratory.

“Certainly the Northeast often has more distribution challenges than much of the rest of the country just because it’s more populous and often the infrastructure is older,” he said. “But it’s not unique to the Northeast — in the Midwest, for example, there’s a significant amount of wind projects in the queues and significant delays.”

In Rhode Island and Massachusetts, where strong incentive programs are driving solar development, the level of solar coming online is “exposing the under-investment in the distribution system that is causing these massive costs that National Grid is assigning to particular projects or particular groups of projects,” McDiarmid said. “It is going to be a limiting factor for how much clean energy we can develop and bring online.”

Frank Epps, chief executive officer at Energy Development Partners, has been developing solar projects in Rhode Island since 2010. In that time, he said, interconnection charges on his projects have grown from about $80,000-$120,000 per megawatt to more than $400,000 per megawatt. He attributed the increase to a lack of investment in the distribution network by National Grid over the last decade.

He and other developers say the utility is now adding further to their costs by passing along not just the cost of improving the distribution system — the equivalent of the city street of the grid that brings power directly to customers — but also costs for modifying the transmission system — the interstate highway that moves bulk power over long distances to substations. 

Solar developers who are only requesting to hook into the distribution system, and not applying for transmission service, say they should not be charged for those additional upgrades under state interconnection rules unless they are properly authorized under the federal law that governs the transmission system. 

A Rhode Island solar and wind developer filed a complaint with the Federal Energy Regulatory Commission in February over transmission system improvement charges for its four proposed solar projects. Green Development said National Grid subsidiaries Narragansett Electric and New England Power Company want to charge the company more than $500,000 a year in operating and maintenance expenses assessed as so-called direct assignment facility charges. 

“This amount nearly doubles the interconnection costs associated with the projects,” which total 38.4 megawatts in North Smithfield, the company says in its complaint. “Crucially, these charges are linked to recovering costs associated with providing transmission service — even though no such transmission service is being provided to Green Development.”

But Ted Kresse, a spokesperson for National Grid, said the direct assignment facility, or DAF, construct has been in place for decades and has been applied to any customer affecting the need for transmission upgrades.

“It is the result of the high penetration and continued high volume of distributed generation interconnections that has recently prompted the need for transmission upgrades, and subsequently the pass-through of the associated DAF charges,” he said. 

Several complaints before the Rhode Island Public Utilities Commission object to these DAF and other transmission charges.

One petition for dispute resolution concerns four solar projects totaling 40 MW being developed by Energy Development Partners in a former gravel pit in North Kingstown. Brown University has agreed to purchase the power. 

The developer signed interconnection service agreements with Narragansett Electric in 2019 requiring payment of $21.6 million for costs associated with connecting the projects at a new Wickford Junction substation. Last summer, Narragansett sought to replace those agreements with new ones that reclassified a portion of the costs as transmission-level costs, through New England Power, National Grid’s transmission subsidiary.

That shift would result in additional operational and maintenance charges of $835,000 per year for the estimated 35-year life of the projects, the complaint says.

“This came as a complete shock to us,” Epps said. “We’re not just paying for the maintenance of a new substation. We are paying a share of the total cost that the system owner has to own and operate the transmission system. So all of the sudden, it makes it even tougher for distributed energy resources to be viable.”

In its response to the petition, National Grid argues that the charges are justified because the solar projects will require transmission-level upgrades at the new substation. The company argues that the developer should be responsible for the costs rather than ratepayers, “who are already supporting renewable energy development through their electric rates.”

Seth Handy, one of the lawyers representing Green Development in the FERC complaint, argues that putting transmission system costs on distribution assets is unfair because the distributed resources are “actually reducing the need to move electricity long distances. We’ve been fighting these fights a long time over the underestimating of the value of distributed energy in reducing system costs.”

Handy is also representing the Episcopal Diocese of Rhode Island before the state Supreme Court in its appeal of an April 2020 public utilities commission order upholding similar charges for a proposed 2.2-megawatt solar project at the diocese’s conference center and camp in Glocester. 

Todd Bianco, principal policy associate at the utilities commission, said neither he nor the chairperson can comment on the pending dockets contesting these charges. But he noted that some of these issues are under discussion in another docket examining National Grid’s standards for connecting distributed generation. Among the proposals being considered is the appointment of an independent ombudsperson to resolve interconnection disputes. 

Separately, legislation pending before the Rhode Island General Assembly would remove responsibility for administering the interconnection of renewable energy from utilities, and put it under the authority of the Rhode Island Infrastructure Bank, a financing agency.

Handy, who recently testified in support of the bill, said he believes National Grid has too many conflicting interests to administer interconnecting charges in a timely, transparent and fair fashion, and pointed to utility moves such as changes to solar compensation in other states as examples. In particular, he noted the company’s interests in expanding natural gas infrastructure. 

“There are all kinds of economic interests that they have that conflict with our state policy to provide lower-cost renewable energy and more secure energy solutions,” Handy said.

In testimony submitted to the House Committee on Corporations opposing the legislation, National Grid said such powers are well beyond the purpose and scope of the infrastructure bank. And it cited figures showing Rhode Island is third in the country for the most installed solar per square mile (behind New Jersey and Massachusetts).

Nadav Enbar, program manager at the Electric Power Research Institute, a nonprofit research organization for the utility industry, said interconnection delays and higher costs are becoming more common due to “the incredible uptake” in distributed renewable energy, particularly solar.

That’s impacting hosting capacity, the room available to connect all resources to a circuit without causing adverse harm to reliability and safety. 

“As hosting capacity is being reduced, it’s causing an increasing number of situations where utilities need to study their systems to guarantee interconnection without compromising their systems,” he said. “And that is the reason why you’re starting to see some delays, and it has translated into some greater costs because of the need for upgrades to infrastructure.”

The cost depends on the age or absence of infrastructure, projected load growth, the number of renewable energy projects in the queue, and other factors, he said. As utilities come under increasing pressure to meet state renewable goals, and as some states pilot incentives like a distributed energy rebate in Illinois to drive utility innovation, some (including National Grid) are beginning to provide hosting capacity maps that provide detailed information to developers and policymakers about the amount of distributed energy that can be accommodated at various locations on the grid, he said. 

In addition, the coming availability of high-tech “smart inverters” should help ease some of these problems because they provide the grid with more flexibility when it comes to connecting and communicating with distributed energy resources, Enbar said. 

In Massachusetts, the Department of Public Utilities has opened a docket to explore ways to better plan for and share the cost of upgrading distribution infrastructure to accommodate solar and other renewable energy sources as part of a grid overhaul for renewables nationwide. National Grid has been conducting “cluster studies” there that attempt to analyze the transmission impacts of a group of solar projects and the corresponding interconnection cost to each developer.

Kresse, of National Grid, said the company favors cost-sharing methodologies under consideration that would “provide a pathway to spread cost over the total enabled capacity from the upgrade, as opposed to spreading the cost over only those customers in the queue today.” 

Solar developers want regulators to take an even broader approach that factors in how the deployment of renewables and the resulting infrastructure upgrades benefit not just the interconnecting generator, but all customers. 

“Right now, if your project is the one that causes a multimillion-dollar upgrade, you are assigned that cost even though that upgrade is going to benefit a lot of other projects, as well as make the grid stronger,” said McDiarmid, of the clean energy council. “What we’re asking for is a way of allocating those costs among a variety of developers, as well as to the grid itself, meaning ratepayers. There’s a societal benefit to increasing the modernization of the grid, and improving the resilience of the grid.”

In the meantime, BlueHub Capital, a Boston-based solar developer focused on serving affordable housing developments, recently learned from National Grid that, as a part of one of the area studies, it will be required to pay $5.8 million in transmission and distribution upgrades to interconnect a 2-megawatt solar-plus-storage project that leverages cheaper batteries to enhance resilience, approved for a brownfield site in Gardner, Massachusetts. 

According to testimony submitted to the department, the sum is supposed to be paid within the next year, even though the project will have to wait to be interconnected until April 2027, when a new transmission line is completed. In addition, BlueHub will be responsible for DAF charges totaling $3.4 million over the 20-year life of the project. 

“We’re being asked to pay a fortune to provide solar that the state wants,” said DeWitt Jones, BlueHub’s president. “It’s so expensive that the upgrades are driving everyone out of the interconnection queue. The costs stay the same, but they fall on fewer projects. We need a process of grid design and modernization to guide this.”

U.S. power demand seen sliding 1% in 2023 on milder weather

EIA U.S. Power Outlook 2023-2024 forecasts lower electricity demand, softer wholesale prices, and faster renewable growth from solar and wind, with steady natural gas, reduced coal generation, slight nuclear gains, and ERCOT market moderation.

 

Key Points

An EIA forecast of a 2023 demand dip, 2024 rebound, lower prices, and a higher renewable share in the U.S. power mix.

✅ Demand dips to 4,000 billion kWh in 2023; rebounds in 2024.

✅ ERCOT on-peak prices average about $35/MWh versus $80/MWh in 2022.

✅ Renewables grow to 24% share; coal falls to 17%; nuclear edges up.

 

U.S. power consumption is expected to slip about 1% in 2023 from the previous year as milder weather slows usage from the record high hit in 2022, consistent with recent U.S. consumption trends observed over the past several years, the U.S. Energy Information Administration (EIA) said in its Short-Term Energy Outlook (STEO).

EIA projected that electricity demand is on track to slide to 4,000 billion kilowatt-hours (kWh) in 2023 from a historic high of 4,048 billion kilowatt-hours (kWh) in 2022, reflecting patterns seen during COVID-19 demand shifts in prior years, before rising to 4,062 billion kWh in 2024 as economic growth ramps up.

Less demand coupled with more electricity generation from cheap renewable power sources and lower natural gas prices is forecast to slash wholesale power prices this year, the EIA said.

The on-peak wholesale price at the North hub in Texas’ ERCOT power market is expected to average about $35 per megawatt-hour (MWh) in 2023 compared with an average of nearly $80/MWh in 2022 after the 2022 price surge in power markets.

As capacity for renewables like solar and wind ramp up and as natural gas prices ease amid the broader energy crisis pressures, the EIA said it expects coal-fired power generation to be 17% less in the spring of 2023 than in the spring of 2022.

Coal will provide an average of 17% of total U.S. generation this year, down from 20% last year, as utilities shift investments toward electricity delivery and away from new power production, the EIA said.

The share of total generation supplied by natural gas is seen remaining at about the same this year at 39%. The nuclear share of generation is seen rising slightly to 20% this year from 19% in 2022. Generation from renewable energy sources grows the most in the forecast, increasing to 24% this year from a share of 22% last year, even as residential electricity bills rose in 2022 across the U.S.
