Canada 100% Renewable Power by 2035 envisions a decentralized grid built on wind, solar, energy storage, and efficiency, delivering zero-emission, resilient, low-cost electricity while phasing out nuclear and gas to meet net-zero targets.

 

Key Points

Zero-emission, decentralized grid using wind, solar, and storage, plus efficiency, to retire fossil and nuclear by 2035.

✅ Scale wind and solar 18x with storage for reliability.

✅ Phase out nuclear and gas; no CCS or offsets needed.

✅ Modernize grids and codes; boost efficiency, jobs, and affordability.

 

A powerful derecho that left nearly a million people without power in Ontario and Quebec on May 21 was a reminder of the critical importance of electricity in our daily lives.

Canada’s electrical infrastructure could be more resilient to such events, while being carbon-emission free and provide low-cost electricity with a decentralized grid powered by 100 per cent renewable energy, according to a new study from the David Suzuki Foundation (DSF), a vision of an electric, connected and clean future if the country chooses.

This could be accomplished by 2035 by building a lot more solar and wind, despite indications that demand for solar electricity has lagged in Canada, adding energy storage, while increasing the energy efficiency in buildings, and modernizing provincial energy grids. As this happens, nuclear energy and gas power would be phased out. There would also be no need for carbon capture and storage nor carbon offsets, the modeling study concluded.

“Solar and wind are the cheapest sources of electricity generation in history,” said study co-author Stephen Thomas, a mechanical engineer and climate solutions policy analyst at the DSF.

“There are no technical barriers to reaching 100 per cent zero-emission electricity by 2035 nationwide,” Thomas told The Weather Network (TWN). However, there are considerable institutional and political barriers to be overcome, he said.

Other countries face similar barriers and many have found ways to reduce their emissions; for example, the U.S. grid's slow path to 100% renewables illustrates these challenges. There are enormous benefits including improved air quality and health, up to 75,000 new jobs annually, and lower electricity costs. Carbon emissions would be reduced by 200 million tons a year by 2050, just over one quarter of the reductions needed for Canada to meet its overall net zero target, the study stated.

Building a net-zero carbon electricity system by 2035 is a key part of Canada’s 2030 Emissions Reduction Plan. Currently over 80 per cent of the nation’s electricity comes from non-carbon sources including a 15 per cent contribution from nuclear, with solar capacity nearing a 5 GW milestone nationally. How the final 20 per cent will be emission-free is currently under discussion.

The Shifting Power study envisions an 18-fold increase in wind and solar energy, with the Prairie provinces expected to lead growth, along with a big increase in Canada’s electrical generation capacity to bridge the 20 per cent gap as well as replacing existing nuclear power.

The report does not see a future role for nuclear power due to the high costs of refurbishing existing plants, including the challenges with disposal of radioactive wastes and decommissioning plants at their end of life. As for the oft-proposed small modular nuclear reactors, their costs will likely “be much more costly than renewables,” according to the report.

There are no technical barriers to building a bigger, cleaner, and smarter electricity system, agrees Caroline Lee, co-author of the Canadian Climate Institute’s study on net-zero electricity, “The Big Switch” released in May. However, as Lee previously told TWN, there are substantial institutional and political barriers.

In many respects, the Shifting Power study is similar to Lee’s study except it phases out nuclear power, forecasts a reduction in hydro power generation, and does not require any carbon capture and storage, she told TWN. Those are replaced with a lot more wind generation and more storage capacity.

“There are strengths and weaknesses to both approaches. We can do either but need a wide debate on what kind of electricity system we want,” Lee said.

That debate has to happen immediately because there is an enormous amount of work to do. When it comes to energy infrastructure, nearly everything “we put in the ground has to be wind, solar, or storage” to meet the 2035 deadline, she said.

There is no path to net zero by 2050 without a zero-emissions electricity system well before that date. Here are some of the necessary steps the report provided:

Create a range of skills training programs for renewable energy construction and installation as well as building retrofits.

Prioritize energy efficiency and conservation across all sectors through regulations such as building codes.

Ensure communities and individuals are fully informed and can decide if they wish to benefit from hosting energy generation infrastructure.

Create a national energy poverty strategy to ensure affordable access.

Strong and clear federal and provincial rules for utilities that mandate zero-emission electricity by 2035.

For Indigenous communities, make sure ownership opportunities are available along with decision-making power.

Canada should move as fast as possible to 100 per cent renewable energy to gain the benefits of lower energy costs, less pollution, and reduced carbon emissions, says Stanford University engineer and energy expert Mark Jacobson.

“Canada has so many clean, renewable energy resources that it is one of the easier countries [that can] transition away from fossil fuels,” Jacobson told TWN.

For the past decade, Jacobson has been producing studies and technical reports on 100 per cent renewable energy, including a new one for Canada, even as Canada is often seen as a solar power laggard today. The Stanford report, A Solution to Global Warming, Air Pollution, and Energy Insecurity for Canada, says a 100 per cent transition by 2035 timeline is ideal. Where it differs from DSF’s Shifting Power report is that it envisions offshore wind and rooftop solar panels which the latter did not.

“Our report is very conservative. Much more is possible,” agrees Thomas.

“We’re lagging behind. Canadians really want to get going on building solutions and getting the benefits of a zero emissions electricity system.”

Electricity subsidies to pulp and paper mills to continue, despite NB Power's rising debt

NB Power Pulp and Paper Subsidies lower electricity rates for six New Brunswick mills using firm power benchmarks and interruptible discounts, while government mandates, utility debt, ratepayer impacts, and competitiveness pressures shape provincial energy policy.

 

Key Points

Provincial mandates that buy down firm electricity rates for six mills to a national average, despite NB Power's debt.

✅ Mandated buy-down to match national firm electricity rates

✅ Ignores large non-firm interruptible power discounts

✅ Raises equity concerns amid NB Power debt and rate pressure

 

An effort to fix NB Power's struggling finances that is supposed to involve a look at "all options" will not include a review of the policy that requires the utility to subsidize electricity prices for six New Brunswick pulp and paper mills, according to the Department of Natural Resources and Energy Development.

The program is meant "to enable New Brunswick's pulp and paper companies have access to competitive priced electricity,"  said the department's communications officer Nick Brown in an email Monday 

"Keeping our large industries competitive with other Canadian jurisdictions, amid Nova Scotia rate hike opposition debates elsewhere, is important," he wrote, knocking down the idea the subsidy program might be scrutinized for shortcomings like other NB Power expenses.

Figures released last week show NB Power paid out $9.7 million in rate subsidies to the mills under the program in the fiscal year ended in March 2021, even though the utility was losing $4 million for the year and falling deeper into debt, amid separate concerns about old meter issues affecting households.

Subsidies went to three mills owned by J.D. Irving Ltd. including two in Saint John and one in Lake Utopia, two owned by the AV group in Nackawic and Atholville and the Twin Rivers pulp mill in Edmundston.

The New Brunswick government has made NB Power subsidize pulp and paper mills like Twin Rivers Paper Company since 2012, and is requiring the program to continue despite financial problems at the utility. (CBC)
It was NB Power's second year in a row of financial losses, while it is supposed to pay down $500 million of its $4.9 billion debt load in the next five years to prepare for the refurbishment of the Mactaquac dam, a burden comparable to customers in Newfoundland paying for Muskrat Falls elsewhere under separate policies, under a directive issued by the province

NB Power president Keith Cronkhite said he was "very disappointed" with debt increasing last year instead of  falling and senior vice president and chief financial officer Darren Murphy said everything would be under the microscope this year to turn the utility's finances around.  

"We need to do better," said Murphy on Thursday

"We need to step back and make sure we're considering all options, including approaches like Newfoundland's ratepayer shield agreement on megaproject overruns, to achieve that objective because the objective is quickly closing in on us."

However, reviewing the subsidy program for the six pulp and paper mills is apparently off limits.

The subsidy program requires NB Power to buy down the cost of "firm" electricity bought by pulp and paper mills to a national average that is calculated by the Department of Natural Resources and Energy Development.

Last year the province declared the price mills in New Brunswick pay to be an average of  7.536 cents per kilowatt hour (kwh).  It is higher than rates in five other provinces that have mills, which the province points to as justification for the subsidies, even as Nova Scotia's 14% rate hike approval highlights broader upward pressure, although the true significance of that difference is not entirely clear.

In British Columbia, the large forest products company Paper Excellence operates five pulp and paper mills which are charged 17.2 per cent less for firm electricity than the six mills in New Brunswick.

The Paper Excellence Paper Mill in Port Alberni, B.C. pays lower electricity prices than mills in New Brunswick, a benefit largely offset by higher property taxes. It's a factor New Brunswick does not count in calculating subsidies NB Power must pay. (Paper Excellence)
However, local property taxes on the five BC mills are a combined $7.8 million higher than the six New Brunswick plants, negating much of that difference.

The province's subsidy formula does not account for differences like that or for the fact New Brunswick mills buy a high percentage of their electricity at cheap non-firm prices.

Not counting the subsidies, NB Power already sells high volumes of what it calls interruptible and surplus power to industry at deep discounts on the understanding it can be cut off and redeployed elsewhere on short notice when needed.

Actual interruptions in service are rare.  Last year there were none, but NB Power sold 837 million kilowatt hours of the discounted power to industry at an average price of 4.9 cents per kwh.   

NB Power does not disclose how much of the $22 million or more in savings went to the six mills, but the price was 35 per cent below NB Power's posted rate for the plants and rivaled firm prices big mills receive anywhere in Canada, including Quebec.

Asked why the subsidy program ignores large amounts of discounted interruptible power used by New Brunswick mills in making comparisons between provinces, Brown said regulations governing the program require a comparison of firm prices only.

"The New Brunswick average rate is based on NB Power's published large industrial rate for firm energy, as required by the Electricity from Renewable Resources regulation," he wrote.

The subsidy program itself was imposed on NB Power by the province in 2012 to aid companies suffering after years of poor markets for forest products following the 2008 financial collapse and recession.  

Providing subsidies has cost NB Power $100 million so far and has continued even as markets for pulp products improved significantly and NB Power's own finances worsened.

Report warned against subsidies
NB Power has never directly criticized the program, but in a matter currently in front the of the New Brunswick Energy and Utilities Board looking at how NB Power might restructure its rates, including proposals such as seasonal rates that could prompt backlash, an independent consultant hired by the utility suggested rate subsidies to large export oriented manufacturing facilities, like pulp and paper mills, is generally a poor idea.

"We do not recommend offering subsidies to exporters," says the report by Christensen Associates Energy Consulting of Madison, Wis.

"There are two serious economic problems with subsidizing exports. The first is that the benefits may be less than the costs. The second problem is that subsidies tend to last forever, even if the circumstances that initially justified the subsidies have disappeared."

The Christensen report did not directly assess the merits of the current subsidy for pulp and paper mills but it addressed the issue because it said in the design of new rates "one NB Power business customer has raised the possibility that their electricity-intensive business ought to be granted subsidies because of the potential to generate extra benefits for the Province through increases in their exports"

That, said Christensen, rarely benefits the public.

"The direct costs of the subsidies are the subsidies themselves, a part of which ends up in the pockets of out-of-province consumers of the exported goods," said the report.  

"But there are also indirect costs due to the fact that the subsidies are financed through higher electricity prices, which means that other electricity customers have less money to spend on services provided by local businesses, thus putting a drag on the local economy."

The province does not agree.

Asked whether it has any studies or cost-benefit reviews that show the subsidy program is a net benefit to New Brunswick, the department cited none but maintained it is an important initiative, even as elsewhere governments have offered electricity bill credit relief to ratepayers.

"The program was designed to give large industrial businesses the ability to compete on a level energy field," wrote Brown.

Restoring power to Florida will take 'weeks, not days' in some areas

Florida Hurricane Irma Power Outages strain the grid as utilities plan rebuilds; FPL and Duke Energy deploy crews to restore transmission lines, substations, and service amid flooding, storm surge, and widespread disruptions statewide.

 

Key Points

Large-scale post-storm power losses in Florida requiring grid rebuilds, thousands of crews, and phased restoration.

✅ Utilities prioritize plants, transmission, substations, then critical facilities

✅ 50,000-60,000 workers mobilized; bucket trucks wait for safe winds

✅ Remote rerouting and hardening aid faster restoration amid flooding

 

Parts of Florida could be without electricity for more than a week, as damage from Hurricane Irma will require a complete rebuild of portions of the electricity grid, utility executives said on Monday.

Irma has knocked out power to 6.5 million Florida electricity customers, or nearly two-thirds of the state, since making landfall this weekend. In major areas such as Miami-Dade, 74 percent of the county was without power, according to Florida's division of emergency management.

Getting that power back online may require the help of 50,000 to 60,000 workers from all over the United States and Canadian power crews as well, according to Southern Company CEO and Chairman Thomas Fanning. He is also co-chair of the Electricity Subsector Coordinating Council, which coordinates the utility industry and government response to disasters and cyberthreats.

While it is not uncommon for severe storms to down power lines and damage utility poles, Irma's heavy winds and rain batted some of the state's infrastructure to the ground, Fanning said.

"'Restore' may not capture the full sense of where we are. For the very hard impacted areas, I think you're in a 'rebuild' area," he told CNBC's "Squawk Box."

"That's a big deal. People need to understand this is going to take perhaps weeks, not days, in some areas," Fanning said.

Parts of northern Florida, including Jacksonville, experienced heavy flooding, which will temporarily prevent crews from accessing some areas.

Duke Energy, which serves 1.8 million customers in parts of central and northwestern Florida, is trying to restore service to 1.2 million residences and businesses.

Florida Power & Light Company, which provides power to an estimated 4.9 million accounts across the state, had about 3.5 million customers without electricity as of Monday afternoon, said Rob Gould, vice president and chief communications officer at FPL.

The initial damage assessments suggest power can be restored to parts of the state's east coast in just days, but some of the west coast will require rebuilding that could stretch out for weeks, Gould told CNBC's "Power Lunch."

"This is not a typical restoration that you're going to see. We actually for the first time in our company history have our entire 27,000-square-mile, 35-county territory under assault by Irma," he said.

FPL said it would first repair any damage to power plants, transmission lines and substations as part of its massive response to Irma, then prioritize critical facilities such as hospitals and water treatment plants. The electricity company would then turn its attention to areas that are home to supermarkets, gas stations and other community services.

Florida utilities invested billions into their systems after devastating hurricane seasons in 2004 and 2005 in order to make them more resilient and easier to restore after a storm. Irma, which ranked among the most powerful storms in the Atlantic, has nevertheless tested those systems.

The upgrades have allowed FPL to automatically reroute power and address about 1.5 million outages, Gould said. The company strategically placed 19,500 restoration workers before the storm hit, but it cannot use bucket trucks to fix power lines until winds die down, he said.

Some parts of Florida's distribution system — the lines that deliver electricity from power plants to businesses and residences — run underground. However, the state's long coastline and the associated danger of storm surge and seawater incursion make it impractical to run lines beneath the surface in some areas.

Duke Energy has equipped 28 percent of its system with smart grid technology to reroute power remotely, according to Harry Sideris, Duke's state president for Florida. He said the company would continue to build out that capability in the future.

Duke deployed more than 9,000 linesmen and support crew members to Irma-struck areas, but cannot yet say how long some customers will be without power.

Separately, Gulf Power crews reported restoring service to more than 32,000 customers.

"At this time we do not know the exact restoration times. However, we're looking at a week or longer from the first look at the widespread damage that we had," Sideris told CNBC's "Closing Bell."

FPL said on Monday it was doing final checks before bringing back nuclear reactors that were powered down as Hurricane Irma hit Florida.

"We are in the process now of doing final checks on a few of them; we will be bringing those up," FPL President and CEO Eric Silagy told reporters.

IEA praises Modi govt for taking electricity to every village; calls India 'star performer'

India Village Electrification hailed by the IEA in World Energy Outlook 2018 showcases rapid energy access progress, universal village power, clean cooking advances via LPG, and Modi-led initiatives, inspiring Indonesia, Bangladesh, and Sub-Saharan Africa.

 

Key Points

A national push to power every Indian village, praised by the IEA for boosting energy access and clean cooking.

✅ Electrified 597,464 villages ahead of schedule in April 2018.

✅ IEA hails India in World Energy Outlook 2018 as star performer.

✅ LPG connections surge via Ujjwala, aiding clean cooking access.

 

The global energy watchdog International Energy Agency (IEA) has called India's electrification of every village the greatest success story of 2018. In its latest report, World Energy Outlook 2018, the IEA has called India a "star performer" in terms of achieving the big milestone of the providing power to each village. "In particular, one of the greatest success stories in access to energy in 2018 was India completing the electrification of all of its villages," said the IEA. It added that countries like Indonesia and Bangladesh have also achieved the commendable electrification rate of 95% (up from 50% in 2000), and 80% (up from 20% in 2000), respectively, even as Europe's electrification push continues as part of broader transitions.

This 643-page report by the IEA says over 120 million people worldwide gained access to electricity in 2017 and charts growth in the electric car market as part of broader energy trends. For the first time ever, the total number of people without access fell below 1 billion, it said.  The mega plan of providing electricity to 597,464 villages in India was announced by Prime Minister Narendra Modi during his Independence Day speech in 2015. On April 28, 2018, PM Modi confirmed that India had achieved its goal ahead of schedule. "This is one of the greatest achievements in the history of energy," said the IEA.

Praising the Narendra Modi government for making efforts towards lighting up every village in India, the agency said: "Since 2000 around half a billion people have gained access to electricity in India, with political effort over the last five years significantly accelerating progress."

India's achievement of providing universal household electricity access will improve the lives of over 230 million people, said the IEA, even as analyses like a Swedfund report debate some poverty outcomes in electrified areas. For a start, electric lighting makes the use of candles, kerosene and other polluting fuels for lighting redundant, not only saving money (and providing more light) but also seriously improving health, it said.

Though the global energy agency has called India "a success story", and a "bright spot for energy access", it says huge challenges remain in other regions of the world where over 670 million people still live without electricity access. "90% of these people are concentrated in sub-Saharan Africa, with countries such as Nigeria facing severe shortages," said the report.

Seven decades after independence and nearly three decades after India's economic liberalisation, the Modi government achieved the historic milestone of giving power to every single village of India, 12 days ahead of the deadline set by PM Modi. Leisang in Manipur became the last village to be connected to the grid, while a Delhi energy storage project explores ways to balance supply and demand.

The agency also praised India for tackling a related problem: access to clean cooking facilities. "While an estimated 780 million people in India rely on biomass for cooking, progress is emerging, as India is one of the few countries in the world targeting this "blind spot" of energy policy," it said.

Around 36 million LPG connections have been made since Prime Minister Modi and Minister for Petroleum and Natural Gas, Dharmendra Pradhan, launched the Pradhan Mantri Ujjwala Yojana scheme in May 2016 to provide free connections to families living below the poverty line. In India, around 50 million free LPG stoves and initial refills have been provided to poor households via this scheme since 2015. The government has set a target of providing LPG connections to 80 million households by 2020.

German renewables deliver more electricity than coal and nuclear power for the first time

Germany renewable energy milestone 2019 saw wind, solar, hydropower, and biomass outproduce coal and nuclear, as low gas prices and high CO2 costs under the EU ETS reshaped the electricity mix, per Fraunhofer ISE.

 

Key Points

It marks H1 2019 when renewables supplied 47.3% of Germany's electricity, surpassing coal and nuclear.

✅ Driven by high CO2 prices and cheap natural gas

✅ Wind and solar output rose; coal generation declined sharply

✅ Flexible gas plants outcompeted inflexible coal units

 

In Lippendorf, Saxony, the energy supplier EnBW is temporarily taking part of a coal-fired power plant offline. Not because someone ordered it — it simply wasn't paying off. Gas prices are low, CO2 prices are high, and with many hours of sunshine and wind, renewable methods are producing a great deal of electricity as part of Germany's energy transition now reshaping operations. And in the first half of the year there was plenty of sun and wind.

The result was a six-month period in which renewable energy sources, a trend echoed by the EU wind and solar record across the bloc, produced more electricity than coal and nuclear power plants together. For the first time 47.3% of the electricity consumers used came from renewable sources, while 43.4% came from coal-fired and nuclear power plants.

In addition to solar and wind power, renewable sources also include hydropower and biomass. Gas supplied 9.3%, reflecting how renewables are crowding out gas across European power markets, while the remaining 0.4% came from other sources, such as oil, according to figures published by the Fraunhofer Institute for Solar Energy Systems in July.

Fabian Hein from the think tank Agora Energiewende stresses that the situation is only a snapshot in time, with grid expansion woes still shaping outcomes. For example, the first half of 2019 was particularly windy and wind power production rose by around 20% compared to the first half of 2018.

Electricity production from solar panels rose by 6%, natural gas by 10%, while the share of nuclear power in German electricity consumption has remained virtually unchanged despite a nuclear option debate in climate policy.

Coal, on the other hand, declined. Black coal energy production fell by 30% compared to the first half of 2018, lignite fell by 20%. Some coal-fired power plants were even taken off the grid, even as coal still provides about a third of Germany's electricity. It is difficult to say whether this was an effect of the current market situation or whether this is simply part of long-term planning, says Hein.

 

Activists storm German mine in anti-coal protest

It is clear, however, that an increased CO2 price has made the ongoing generation of electricity from coal more expensive. Gas-fired power plants also emit CO2, but less than coal-fired power plants. They are also more efficient and that's why gas-fired power plants are not so strongly affected by the CO2 price

The price is determined at a European level and covers power plants and energy intensive industries in Europe. Other areas, such as heating or transport are not covered by the CO2 price scheme. Since a reform of CO2 emissions trading in 2017, the price has risen sharply. Whereas in September 2016 it was just over €5 ($5.6), by the end of June 2019 it had climbed to over €26.

 

Ups and downs

Gas as a raw material is generally more expensive than coal. But coal-fired power plants are more expensive to build. This is why operators want to run them continuously. In times of high demand, and therefore high prices, gas-fired power plants are generally started up, as seen when European power demand hit records during recent heatwaves, since it is worth it at these times.

Gas-fired power plants can be flexibly ramped up and down. Coal-fired power plants take 11 hours or longer to get going. That's why they can't be switched on quickly for short periods when prices are high, like gas-fired power plants. In the first half of the year, however, coal-fired power plants were also ramped up and down more often because it was not always worthwhile to let the power plant run around the clock.

Because gas prices were particularly low in the first half of 2019, some gas-fired power plants were more profitable than coal-fired plants. On June 29, 2019, the gas price at the Dutch trading point TTF was around €10 per megawatt hour. A year earlier, it had been almost €20. This is partly due to the relatively mild winter, as there is still a lot of gas in reserve, confirmed a spokesman for the Federal Association of the Energy and Water Industries (BDEW). There are also several new export terminals for liquefied natural gas. Additionally, weaker growth and trade wars are slowing demand for gas. A lot of gas comes to Europe, where prices are still comparatively high, reported the Handelsblatt newspaper.

The increase in wind and solar power and the decline in nuclear power have also reduced CO2 emissions. In the first half of 2019, electricity generation emitted around 15% less CO2 than in the same period last year, reported BDEW. However, the association demands that the further expansion of renewable energies should not be hampered. The target of 65% renewable energy can only be achieved if the further expansion of renewable energy sources is accelerated.

Community-generated green electricity to be offered to all in UK

Community Power Tariff UK delivers clean electricity from community energy projects, sourcing renewable energy from local wind and solar farms, with carbon offset gas, transparent provenance, fair pricing, and reinvestment in local generators across Britain.

 

Key Points

UK energy plan delivering 100% community renewable power with carbon-offset gas, sourced from local wind and solar.

✅ 100% community-generated electricity from UK wind and solar

✅ Fair prices with profits reinvested in local projects

✅ Carbon-offset gas and verified, transparent provenance

 

UK homes will soon be able to plug into community wind and solar farms from anywhere in the country through the first energy tariff to offer clean electricity exclusively from community projects.

The deal from Co-op Energy comes as green energy suppliers race to prove their sustainability credentials amid rising competition for eco-conscious customers and “greenwashing” in the market.

The energy supplier will charge an extra £5 a month over Co-op’s regular tariff to provide electricity from community energy projects and gas which includes a carbon offset in the price.

Co-op, which is operated by Octopus Energy after it bought the business from the Midcounties Co-operative last year, will source the clean electricity for its new tariff directly from 90 local renewable energy generation projects across the UK, including the Westmill wind and solar farms in Oxfordshire. It plans to use all profits to reinvest in maintaining the community projects and building new ones.

Phil Ponsonby, the chief executive of Midcounties Co-operative, said the tariff is the UK’s only one to be powered by 100% community-generated electricity and would ensure a fair price is paid to community generators too, amid a renewable energy auction boost that supports wider deployment.

Customers on the Community Power tariff will be able to “see exactly where it is being generated at small scale sites across the UK, and, with new rights to sell solar power back to energy firms, they know it is benefiting local communities”, he said.

Co-op, which has about 300,000 customers, has set itself apart from a rising number of energy supply deals which are marked as 100% renewable, but are not as green as they seem, even as many renewable projects are on hold due to grid constraints.

Consumer group Which? has found that many suppliers offer renewable energy tariffs but do not generate renewable electricity themselves or have contracts to buy any renewable electricity directly from generators.

Instead, the “pale green” suppliers exploit a loophole in the energy market by snapping up cheap renewable energy certificates, without necessarily buying energy from renewables projects.

The certificates are issued by the regulator to renewable energy developers for each megawatt generated, but these can be sold separately from the electricity for a fraction of the price.

A survey conducted last year found that one in 10 people believe that a renewables tariff means that the supplier generates at least some of its electricity from its own renewable energy projects.

Ponsonby said the wind and solar schemes that generate electricity for the Community Power tariff “plough the profits they make back into their neighbourhoods or into helping other similar projects get off the ground”.

Greg Jackson, the chief executive of Octopus Energy, said being able to buy locally-sourced clean, green energy is “a massive jump in the right direction” which will help grow the UK’s green electricity capacity nationwide.

“Investing in more local energy infrastructure and getting Britain’s homes run by the sun when it’s shining and wind energy when it’s blowing can end our reliance on dirty fossil fuels sooner than we hoped,” he said.

San Diego Gas & Electric Orders Mitsubishi Power Emerald Storage Solution

SDG&E Mitsubishi Power Energy Storage adds a 10 MW/60 MWh BESS in Pala, boosting grid reliability, renewable integration, and flexibility with EMS and SCADA controls, LFP safety chemistry, NERC CIP compliance, UL 9540 standards.

 

Key Points

A 10 MW/60 MWh BESS for SDG&E in Pala that enhances grid reliability, renewables usage, and operational flexibility.

✅ Emerald EMS/SCADA meets NERC CIP, IEC/ISA 62443, NIST 800-53

✅ LFP chemistry with UL 9540 and UL 9540A safety compliance

✅ Adds capacity, energy, and ancillary services to CA grid

 

San Diego Gas & Electric Company (SDG&E), a regulated public utility that provides energy service to 3.7 million people, has awarded Mitsubishi Power an order for a 10 megawatt (MW) / 60 megawatt-hour (MWh) energy storage solution for its Pala-Gomez Creek Energy Storage Project in Pala, California. The battery energy storage system (BESS) will add capacity to help meet high energy demand, support grid reliability and operational flexibility, underscoring the broader benefits of energy storage now recognized by utilities, maximize use of renewable energy, and help prevent outages during peak demand.

The BESS project is Mitsubishi Power’s eighth in California, bringing total capacity to 280 MW / 1,140 MWh of storage to help meet California’s clean energy goals with reliable power to complement renewables, alongside emerging solutions like a California green hydrogen microgrid for added resilience.

Mitsubishi Power’s Emerald storage solution for SDG&E includes full turnkey design, engineering, procurement, and construction, as well as a 10-year long-term service agreement, aligning with CEC long-duration storage funding initiatives underway. It is scheduled to be online in early 2023.

The project will repower an existing energy storage site. It will employ Mitsubishi Power’s Emerald Integrated Plant Controller, which is an Energy Management System (EMS) and Supervisory Control and Data Acquisition (SCADA) system with real-time BESS operation and a monitoring/supervisory control platform. Mitsubishi Power leverages its decades of technology monitoring and diagnostics to turn data into actionable insights to maximize reliability, a priority as regions like Ontario increasingly rely on battery storage to meet rising demand. The Mitsubishi Power Emerald Integrated Plant Controller complies with North American Electric Reliability Corporation critical infrastructure protection (NERC CIP) standards and meets the highest security certification in the energy storage industry (IEC/ISA 62443, NIST 800-53) for maximum protection from cybersecurity risks and vulnerabilities.

For added physical safety, Mitsubishi Power’s solution employs lithium iron phosphate (LFP) battery chemistry, aligning with BESS adoption in New York where safety and performance are critical. Compared with other chemistries, LFP provides longer life and superior thermal stability and chemical stability, while meeting UL 9540 and UL 9540A safety standards.
