Change would have to occur for Wesleyville to be considered for future energy production, an Ontario Power Generation (OPG) official told Port Hope council recently.

In response to a question by Coun. Karen O'Hara, Patrick McNeil said various events must occur and needs must increase significantly before the federal government would consider constructing a new site.

"Wesleyville is well known as a potential site, but the federal government is focused on existing sites," he said. "OPG is quite willing to entertain the Wesleyville site, if government policy changes."

The senior vice-president of nuclear generation development for OPG, Mr. McNeil was at the meeting to share plans for expanding the Darlington nuclear site, which includes up to four units capable with up to 4,800 megawatts of electrical capacity.

"We don't know the number of units or what size they will be," Mr. McNeil told council. In June 2006, the energy minister gave OPG the go-ahead to begin the federal approvals process, including the environmental assessment (EA), for siting potential new nuclear generation at Darlington.

The size and number would depend on future power needs, and is estimated for completion in 2018 to 2025.

Mr. McNeil said it seems a long way away, but the EA process alone could take up to five years. It includes studies of the impacts of the generating station on human health, safety and security, adjacent water, the economy, climate change and more, and all within a 60-kilometre radius.

The next stage, site preparation and construction, would employ between 2,000 and 2,500 people; it is estimated for completion no later than 2025. Between 700 and 1,000 full-time workers would be expected to be employed at a plant that is up and running.

Public consultation is part of the process and Mr. McNeil said a round of community information sessions are slated in various communities beginning November 7 and ending November 22. A session will be held at Port Hope's Town Park Recreation Centre on Monday, Nov. 12, from 3 to 9 p.m. with a presentation at 7 p.m.

"We are working very hard to be open and transparent," he said. "We want to involve the people and want their support as we move forward. And we go out of our way to give people that opportunity." As for the Wesleyville site, a recent notice for a rezoning request for proposed gun ranges there had one resident expressing concern.

"The fate of Wesleyville is in your hands," Port Hope resident Sandford Haskill told council. "If you allow the shooting range, you can say good-bye to Wesleyville."

The rezoning request for a portion of OPG land stems from a seven-year agreement between OPG and Durham Regional Police Services which ends in 2013. The company is now looking at its own employees to provide the security, with training on two proposed weapons firing ranges.

California Considers Revamping Electricity Rates in Bid to Clean the Grid

California Electricity Rate Overhaul proposes a fixed fee and lower per-kWh rates to boost electrification, renewables, and grid reliability, while CPUC weighs impacts on conservation, low-income customers, and time-of-use pricing across the state.

 

Key Points

A proposal to add fixed fees and cut per-kWh prices to drive electrification, support renewables, and balance grid costs.

✅ Fixed monthly fee plus lower volumetric per-kWh charges

✅ Aims to accelerate EVs, heat pumps, and building electrification

✅ CPUC review weighs equity, conservation, and grid reliability

 

California is contemplating a significant overhaul to its electricity rate structure that could bring major changes to electric bills statewide, a move that has ignited debate among environmentalists and politicians alike. The proposed modifications, spearheaded by the California Energy Commission (CEC), would introduce a fixed fee on electric bills and lower the rate per kilowatt-hour (kWh) used.

 

Motivations for the Change

Proponents of the plan argue that it would incentivize Californians to transition to electric appliances and vehicles, a critical aspect of the state's ambitious climate goals. They reason that a lower per-unit cost would make electricity a more attractive option for applications like home heating and transportation, which are currently dominated by natural gas and gasoline. Additionally, they believe the plan would spur investment in renewable energy sources and distributed generation, ultimately leading to a cleaner electricity grid.

California has some of the most ambitious climate goals in the country, aiming to achieve carbon neutrality by 2045. The transportation sector is the state's largest source of greenhouse gas emissions, and electrification is considered a key strategy for reducing emissions. A 2021 report by the Natural Resources Defense Council (NRDC) found that electrifying all California vehicles and buildings could reduce greenhouse gas emissions by 80% compared to 2020 levels.

 

Concerns and Potential Impacts

Opponents of the proposal, including some consumer rights groups, express apprehensions that it would discourage conservation efforts. They argue that with a lower per-kWh cost, Californians would have less motivation to reduce their electricity consumption. Additionally, they raise concerns that the income-based fixed charges could disproportionately burden low-income households, who may struggle to afford the base charge regardless of their overall electricity consumption.

A recent study by the CEC suggests that the impact on most Californians would be negligible, even as regulators face calls for action over soaring bills from ratepayers across the state. The report predicts that the average household's electricity bill would change by less than $5 per month under the proposed system. However, some critics argue that this study may not fully account for the potential behavioral changes that could result from the new rate structure.

 

Similar Initiatives and National Implications

California is not the only state exploring changes to its electricity rates to promote clean energy. Hawaii and New York have also implemented similar programs to encourage consumers to use electricity during off-peak hours. These time-varying rates, also known as time-of-use rates, can help reduce strain on the electricity grid during peak demand periods.

The California proposal has garnered national attention as other states grapple with similar challenges in balancing clean energy goals with affordability concerns amid soaring electricity prices in California and beyond. The outcome of this debate could have significant implications for the broader effort to decarbonize the U.S. power sector.

 

The Road Ahead

The California Public Utilities Commission (CPUC) is reviewing the proposal and anticipates making a decision later this year, with a potential income-based flat-fee structure under consideration. The CPUC will likely consider the plan's potential benefits and drawbacks, including its impact on greenhouse gas emissions, electricity costs for consumers, and the overall reliability of the grid, even as some lawmakers seek to overturn income-based charges in the legislature.

The decision on California's electricity rates is merely one piece of the puzzle in the fight against climate change. However, it is a significant one, with the potential to shape the state's energy landscape for years to come, including the future of residential rooftop solar markets and investments.

Minnesota Power energizes Great Northern Transmission Line

Great Northern Transmission Line delivers 250 MW of carbon-free hydropower from Manitoba Hydro, strengthening Midwest grid reliability, enabling wind storage balancing, and advancing Minnesota Power's EnergyForward strategy for cleaner, renewable energy across the region.

 

Key Points

A 500 kV cross-border line delivering 250 MW of carbon-free hydropower, strengthening reliability and enabling renewables.

✅ 500 kV, 224-mile line from Manitoba to Minnesota

✅ Delivers 250 MW hydropower via ALLETE-Minnesota Power

✅ Enables wind storage and grid balancing with Manitoba Hydro

 

Minnesota Power, a utility division of ALLETE Inc. (NYSE:ALE), has energized its Great Northern Transmission Line, bringing online an innovative delivery and storage system for renewable energy that spans two states and one Canadian province, similar to the Maritime Link project in Atlantic Canada.

The 500 kV line is now delivering 250 megawatts of carbon-free hydropower from Manitoba, Canada, to Minnesota Power customers.

Minnesota Power completed the Great Northern Transmission Line (GNTL) in February 2020, ahead of schedule and under budget. The 224-mile line runs from the Canadian border in Roseau County to a substation near Grand Rapids, Minnesota. It consists of 800 tower structures which were fabricated in the United States and used 10,000 tons of North American steel. About 2,200 miles of wire were required to install the line's conductors. The GNTL also is contributing significant property tax revenue to local communities along the route.

"This is such an incredible achievement for Minnesota Power, ALLETE, and our region, and is the culmination of a decade-long vision brought to life by our talented and dedicated employees," said ALLETE President and CEO Bethany Owen. "The GNTL will help Minnesota Power to provide our customers with 50 percent renewable energy less than a year from now. As part of our EnergyForward strategy, it also strengthens the grid across the Midwest and in Canada, enhancing reliability for all of our customers."

With the GNTL energized and connected to Manitoba Hydro's recently completed Manitoba-Minnesota Transmission Project at the border, the companies now have a unique "wind storage" mechanism that quickly balances energy supply and demand in Minnesota and Manitoba, and enables a larger role for renewables in the North American energy grid.

The GNTL and its delivery of carbon-free hydropower are important components of Minnesota Power's EnergyForward strategy to transition away from coal and add renewable power sources while maintaining reliable and affordable service for customers, echoing interties like the Maritime Link that facilitate regional power flows. It also is part of a broader ALLETE strategy to advance and invest in critical regional transmission and distribution infrastructure, such as the TransWest Express transmission project, to ensure grid integrity and enable cleaner energy to reduce carbon emissions.

"The seed for this renewable energy initiative was planted in 2008 when Minnesota Power proposed purchasing 250 megawatts of hydropower from Manitoba Hydro. Beyond the transmission line, it also included a creative asset swap to move wind power from North Dakota to Minnesota, innovative power purchase agreements, and a remarkable advocacy process to find an acceptable route for the GNTL," said ALLETE Executive Chairman Al Hodnik. "It marries wind and water in a unique connection that will help transform the energy landscape of North America and reduce carbon emissions related to the existential threat of climate change."

Minnesota Power and Manitoba Hydro, a provincial Crown Corporation, coordinated on the project from the beginning, navigating National Energy Board reviews along the way. It is based on the companies' shared values of integrity, environmental stewardship and community engagement.

"The completion of Minnesota Power's Great Northern Transmission Line and our Manitoba-Minnesota Transmission Project is a testament to the creativity, perseverance, cooperation and skills of hundreds of people over so many years on both sides of the border," said Jay Grewal, president and CEO of Manitoba Hydro. "Perhaps even more importantly, it is a testament to the wonderful, longstanding relationship between our two companies and two countries. It shows just how much we can accomplish when we all work together toward a common goal."

Minnesota Power engaged federal, state and local agencies; the sovereign Red Lake Nation and other tribes, reflecting First Nations involvement in major transmission planning; and landowners along the proposed routes beginning in 2012. Through 75 voluntary meetings and other outreach forums, a preferred route was selected with strong support from stakeholders that was approved by the Minnesota Public Utilities Commission in April 2016.

A four-year state and federal regulatory process culminated in late 2016 when the federal Department of Energy approved a Presidential Permit for the GNTL, similar to the New England Clean Power Link process, needed because of the international border crossing. Construction of the line began in early 2017.

"A robust stakeholder process is essential to the success of any project, but especially when building a project of this scope," Owen said. "We appreciated the early engagement and support from stakeholders, local communities and tribes, agencies and regulators through the many approval milestones to the completion of the GNTL."

Alberta's Rising Electricity Prices

Alberta Last-Resort Power Rate Reform outlines consumer protection against market volatility, price spikes, and wholesale rate swings, promoting fixed-rate plans, price caps, transparency, and stable pricing mechanisms within Alberta's deregulated power market.

 

Key Points

Alberta Last-Resort Power Rate Reform seeks stable, transparent pricing and stronger consumer protections.

✅ Caps or hedges shield bills from wholesale price spikes

✅ Expand fixed-rate options and enrollment nudges

✅ Publish clear, real-time pricing and market risk alerts

 

Alberta’s electricity market is facing growing instability, with rising prices leaving many consumers struggling. The province's rate of last resort, a government-set price for people who haven’t chosen a fixed electricity plan, has become a significant concern. Due to volatile market conditions, this rate has surged, causing financial strain for households. Experts, like energy policy analyst Blake Shaffer, argue that the current market structure needs reform. They suggest creating more stability in pricing, ensuring better protection for consumers against unexpected price spikes, and addressing the flaws that lead to market volatility.

As electricity prices climb, many consumers are feeling the pressure. In Alberta, where energy deregulation is the norm in the electricity market, people without fixed-rate plans are automatically switched to the last-resort rate when their contracts expire. This price is based on fluctuating wholesale market rates, which can spike unexpectedly, leaving consumers vulnerable to sharp price increases. For those on tight budgets, such volatility makes it difficult to predict costs, leading to higher financial stress.

Blake Shaffer, a prominent energy policy expert, has been vocal about the need to address these issues. He has highlighted that while some consumers benefit from fixed-rate plans, with experts urging Albertans to lock in rates when possible, those who cannot afford them or who are unaware of their options often find themselves stuck with the unpredictable last-resort rate. This rate can be substantially higher than what a fixed-plan customer would pay, often due to rapid shifts in energy demand and supply imbalances.

Shaffer suggests that the province’s electricity market needs a restructuring to make it more consumer-friendly and less vulnerable to extreme price hikes. He argues that introducing more transparency in pricing and offering more stable options for consumers through new electricity rules could help. In addition, there could be better incentives for consumers to stay informed about their electricity plans, which would help reduce the number of people unintentionally placed on the last-resort rate.

One potential solution proposed by Shaffer and others is the creation of a more predictable and stable pricing mechanism, though a Calgary electricity retailer has urged the government to scrap an overhaul, where consumers could have access to reasonable rates that aren’t so closely tied to the volatility of the wholesale market. This could involve capping prices or offering government-backed insurance against large price fluctuations, making electricity more affordable for those who are most at risk.

The increasing reliance on market-driven prices has also raised concerns about Alberta’s energy policy changes and overall direction. As a province with a large reliance on oil and gas, Alberta’s energy sector is tightly connected to global energy trends. While this has its benefits, it also means that Alberta’s electricity prices are heavily influenced by factors outside the control of local consumers, such as geopolitical issues or extreme weather events. This makes it hard for residents to predict and plan their energy usage and costs.

For many Albertans, the current state of the electricity market feels precarious. As more people face unexpected price hikes, calls for a market overhaul continue to grow louder across Alberta. Shaffer and others believe that a new framework is necessary—one that balances the interests of consumers, the government, and energy companies, while ensuring that basic energy needs are met without overwhelming households with excessive costs.

In conclusion, Alberta’s last-resort electricity rate system is an increasing burden for many. While some may benefit from fixed-rate plans, others are left exposed to market volatility. Blake Shaffer advocates for reform to create a more stable, transparent, and affordable electricity market, one that could better protect consumers from the high risks associated with deregulated pricing. Addressing these challenges will be crucial in ensuring that energy remains accessible and affordable for all Alberta residents.

Hinkley C nuclear reactor roof lifted into place

Hinkley Point C dome lift marks a nuclear reactor milestone in Somerset, as EDF used Big Carl crane to place a 245-tonne steel roof, enabling 2027 startup amid costs, delays, and precision indoor welding.

 

Key Points

A 245-tonne dome lifted onto Hinkley Point C's first reactor, finishing the roof and enabling fit-out for a 2027 startup.

✅ 245-tonne steel dome lifted by Big Carl onto 44m-high reactor

✅ Indoor welding avoided weather defects seen at Flamanville

✅ Cost now £33bn; first power targeted by end of 2027

 

Engineers have lifted a steel roof onto a building which will house the first of two nuclear reactors at Hinkley Point in Somerset.

Hundreds of people helped with the delicate operation to get the 245-tonne steel dome into position.

It means the first reactor can be installed next year, ready to be switched on in June 2027.

Engineers at EDF said the "challenging job" was completed in just over an hour.

They first broke the ground on the new nuclear station in March 2017. Now, some 10,000 people work on what is Europe's largest building site.

Yet many analysts note that Europe is losing nuclear power even as demand for reliable energy grows.

They have faced delays from Covid restrictions and other recent setbacks, and the budget has doubled to £33bn, so getting the roof on the first of the two reactor buildings is a big deal.

EDF's nuclear island director Simon Parsons said it was a "fantastic night".

"Lifting the dome into place is a celebration of all the work done by a fantastic team. The smiles on people's faces this morning were something else.

"Now we can get on with the fitting of equipment, pipes and cables, including the first reactor which is on site and ready to be installed next year."

Nuclear minister Andrew Bowie hailed the "major milestone" in the building project, citing its role in the UK's green industrial revolution ambitions.

He said: "This is a key part of the UK Government's plans to revitalise nuclear."

But many still question whether Hinkley Point C will be worth all the money, especially after Hitachi's project freeze in Britain, with Roy Pumfrey of the Stop Hinkley campaign describing the project as "shockingly bad value".


Why lift the roof on?

The steel dome is bigger than the one on St Paul's Cathedral in London.

To lift it onto the 44-metre-high reactor building, they needed the world's largest land-based crane, dubbed Big Carl by engineers.

So why not just build the roof on top of the building?

The answer lies in a remote corner of Normandy in France, near a village called Flamanville.

EDF has been building a nuclear reactor there since 2007, ten years before they started in west Somerset.

The project is now a decade behind schedule and has still not been approved by French regulators.

Why? Because of cracks found in the precision welding on the roof of the reactor building.

In nuclear-powered France, they built the roof in situ, out in the open. 

Engineers have decided welding outside, exposed to wind and rain, compromised the high standards needed for a nuclear reactor.

So in Somerset they built a temporary workshop, which looks like a fair sized building itself. All the welding has been done inside, and then the completed roof was lifted into place.


Is it on time or on budget?

No, neither. When Hinkley C was first approved a decade ago, EDF said it would cost £14bn.

Four years later, in 2017, they finally started construction. By now the cost had risen to £19.5bn, and EDF said the plant would be finished by the end of 2025.

Today, the cost has risen to £33bn, and it is now hoped Hinkley C will produce electricity by the end of 2027.

"Nobody believes it will be done by 2027," said campaigner Roy Pumfrey.

"The costs keep rising, and the price of Hinkley's electricity will only get dearer," they added.

On the other hand, the increase in costs is not a problem for British energy bill payers, or the UK government.

EDF agreed to pay the full cost of construction, including any increases.

When I met Grant Shapps, then the UK Energy Secretary, at the site in April, he shrugged off the cost increases.

He said: "I think we should all be rather pleased it is not the British tax payer - it is France and EDF who are paying."

In return, the UK government agreed a set rate for Hinkley's power, called the Strike Price, back in 2013. The idea was this would guarantee the income from Hinkley Point for 35 years, allowing investors to get their money back.


Will it be worth the money?

Back in 2013, the Strike Price was set at £92.50 for each megawatt hour of power. At the time, the wholesale price of electricity was around £50/MWh, so Hinkley C looked expensive.

But since then, global shocks like the war in Ukraine have increased the cost of power substantially, and advocates argue next-gen nuclear could deliver smaller, cheaper, safer designs.

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.”

Lawa Hydropower Station approved on the Jinsha River, a Yangtze tributary, delivers 2,000 MW via four units; 784 ft dam, 12 sq mi reservoir, Sichuan-Tibet site, US$4.59b investment, Huadian stake, renewable energy generation.

 

Key Points

A 2,000 MW dam project on the Jinsha River with four units, a 784 ft barrier, and 8.36 billion kWh annual output.

✅ Sichuan-Tibet junction on the Jinsha River

✅ 2,000 MW capacity; four turbine-generator units

✅ 8.36 bn kWh/yr; US$4.59b total; Huadian 48% stake

 

China has approved construction of the 2,000-MW Lawa hydropower station, a Yangtze tributary hydropower project on the Jinsha River, multiple news agencies are reporting.

Lawa, at the junction of Sichuan province and the Tibet autonomous region, will feature a 784-foot-high dam and the reservoir will submerge about 12 square miles of land. The Jinsha River is a tributary of the Yangtze River, and the project aligns with green hydrogen development in China.

The National Development and Reform Commission of the People’s Republic of China, which also guides China's nuclear energy development as part of national planning, is reported to have said that four turbine-generator units will be installed, and the project is expected to produce about 8.36 billion kWh of electricity annually.

Total investment in the project is to be US$4.59 billion, and Huadian Group Co. Ltd. will have a 48% stake in the project, reflecting overseas power infrastructure activity, with minority stakes held by provincial firms, according to China Daily.

In other recent news in China, Andritz received an order in December 2018 to supply four 350-MW reversible pump-turbines and motor-generators, alongside progress in compressed air generation technologies, for the 1,400-MW ZhenAn pumped storage plant in Shaanxi province.
