Solar and wind power curtailments are rising in California

California NEM-3 Tariff ushers a successor Net Energy Metering framework, revising export compensation, TOU rates, and non-bypassable charges to balance ratepayer impacts, rooftop solar growth, and energy storage adoption across diverse communities.

Key Points

The CPUC's successor NEM policy redefining export credits and rates to sustain customer-sited solar and storage.

✅ Sets export compensation methodology beyond NEM 2.0

✅ Aligns TOU rates and non-bypassable charges with costs

✅ Encourages solar-plus-storage adoption and equity access

The California Public Utilities Commission (CPUC) has officially commenced its “NEM-3” proceeding, which will establish the successor Net Energy Metering (NEM) tariff to the “NEM 2.0” program in California. This is a highly anticipated, high-stakes proceeding that will effectively modify the rules for the NEM tariff in California, amid ongoing electricity pricing changes that affect residential rooftop solar – arguably the single most important policy mechanism for customer-sited solar over the last decade.

The CPUC’s recent order instituting rule-making (OIR) filing stated that “the major focus of this proceeding will be on the development of a successor to existing NEM 2.0 tariffs. This successor will be a mechanism for providing customer-generators with credit or compensation for electricity generated by their renewable facilities that a) balances the costs and benefits of the renewable electrical generation facility and b) allows customer-sited renewable generation to grow sustainably among different types of customers and throughout California’s diverse communities.”

This successor tariff proceeding was initiated by Assembly Bill 327, which was signed into law in October of 2013. AB 327 is best known as the legislation that directed the CPUC to create the “NEM 2.0” successor tariff, which was adopted by the CPUC in January of 2016.

The original Net Energy Metering program in California (“NEM 1.0”) effectively enabled full-retail value net metering “allowing NEM customers to be compensated for the electricity generated by an eligible customer-sited renewable resource and fed back to the utility over an entire billing period.” Under the NEM 2.0 tariff, customers were required to pay charges that aligned them more closely with non-NEM customer costs than under the original structure. The main changes adopted when the NEM 2.0 was implemented were that NEM 2.0 customer-generators must: (i) pay a one-time interconnection fee; (ii) pay non-bypassable charges on each kilowatt-hour of electricity they consume from the grid; and (iii) customers were required to transfer to a time-of-use (TOU) rate, with potential changes to electric bills for many customers.

NEM 2.0

The commencement of the NEM-3 OIR was preceded by the publishing of a 318-page Net Energy Metering 2.0 Lookback Study, which was published by Itron, Verdant Associates, and Energy and Environmental Economics. The CPUC-commissioned study had been widely anticipated and was expected to act as the starting reference point for the successor tariff proceeding. Verdant also hosted a webinar, which summarized the study’s inputs, assumptions, draft findings and results.

The study utilized several different tests to study the impact of NEM 2.0. The cost effectiveness analysis tests, which estimate costs and benefits attributed to NEM 2.0 include: (i) total resource cost test, (ii) participant cost test, (iii) ratepayer impact measure test, and (iv) program administrator test. The evaluation also included a cost of service analysis, which estimates the marginal cost borne by the utility to serve a NEM 2.0 customer.

The opening paragraph of the report’s executive summary stated that “overall, we found that NEM 2.0 participants benefit from the structure, while ratepayers see increased rates.” In every test that the author’s conducted the results generally supported this conclusion for residential customers. There were some exceptions in their findings. For example, in the cost of service analysis the report stated that “residential customers that install customer-sited renewable resources on average pay lower bills than the utility’s cost to serve them. On the other hand, nonresidential customers pay bills that are slightly higher than their cost of service after installing customer-sited renewable resources. This is largely due to nonresidential customer rates having demand charges (and other fixed fees), and the lower ratio of PV system size to customer load when compared to residential customers.”

Similar debates over solar rate design, including Massachusetts solar demand charges, highlight how demand charges and TOU decisions can affect customer economics.

NEM-3 timeline

Popular content
The preliminary schedule that the CPUC laid out in its OIR estimates that the proceeding will take roughly 15 months in total, starting with a November 2020 pre-hearing conference.

The real meat of the proceeding, where parties will present their proposals for what they believe the successor tariff should be, as the state considers revamping electricity rates to clean the grid, and really show their hand will not begin until the Spring of 2021. So we’re still a little ways away from seeing the proposals that the key parties to this proceeding, like the Investor Owned Utilities (PG&E, SCE, SDG&E), solar and storage advocates such as SEIA, CALSSA, Vote Solar, and ratepayer advocates like TURN) will submit.

While the outcome for the new successor NEM tariff is anyone’s guess at this point, some industry policy folks are starting to speculate. We think it is safe to assume that the value of exported energy will get reduced, with debates over income-based utility charges also influencing rate design. How much and the mechanism for how exports get valued remains to be seen. Based on the findings from the lookback study, it seems like the reduction in export value will be more severe than what happened when NEM 2.0 got implemented. In NEM 2.0, non-bypassable charges, which are volumetric charges that must be paid on all imported energy and cannot be netted-out by exports, only equated to roughly $0.02 to $0.03/kWh.

Given that the value of exports will almost certainly get reduced, we expect that to be bullish for energy storage as America goes electric and load shapes evolve. Energy storage attachment rates with solar are already steadily rising in California. By the time NEM-3 starts getting implemented, likely in 2022, we think storage attachment rates will likely escalate further.

We would not be surprised to see future storage attachment rates in California look like the Hawaiian market today, which are upwards of 80% for certain types of customers and applications. Two big questions on our mind are: (i) will the NEM 3.0 rules be different for different customer class: residential, CARE (e.g., low-income or disadvantaged communities), and commercial & industrial; (ii) will the CPUC introduce some sort of glidepath or phased in implementation approach?

The outcome of this proceeding will have far reaching implications on the future of customer-sited solar and energy storage in California. The NEM-3 outcome in California may likely serve as precedent for other states, as California exports its energy policies across the West, and utility territories that are expected to redesign their Net Energy Metering tariffs in the coming years.

Canada Green Investment Gap highlights lagging EV and clean energy funding as peers surge. With a green recovery budget pending, sustainable finance, green bonds, EV charging, hydrogen, and carbon capture are pivotal to decarbonization.

Key Points

Canada lags peers in EV and clean energy investment, urging faster budget and policy action to cut emissions.

✅ Per capita climate spend trails US and EU benchmarks

✅ EVs, hydrogen, charging need scaled funding now

✅ Strengthen sustainable finance, green bonds, disclosure

Canada is being outpaced on the international stage when it comes to green investments in electric vehicles and green energy solutions, environmental groups say.

The federal government has an opportunity to change course in about three weeks, when the Liberals table their first budget in over two years, the International Institute for Sustainable Development (IISD) argued in a new analysis endorsed by nine other climate action, ecology and conservation organizations.

“Canada’s international peers are ramping up commitments for green recovery, including significant investments from many European countries,” states the analysis, “Investing for Tomorrow, Today,” published March 29.

“To keep up with our global peers, sufficient investments and strengthened regulations, including EV sales regulations, must work in tandem to rapidly decarbonize all sectors of the Canadian economy.”

Deputy Prime Minister and Finance Minister Chrystia Freeland confirmed last week that the federal budget will be tabled April 19. The Liberals are expected to propose between $70 billion and $100 billion in fiscal stimulus to jolt the economy out of its pandemic doldrums.

The government teased a coming economic “green transformation” late last year when Freeland released the fall economic statement, promising to examine federal green bonds, border carbon adjustments and a sustainable finance market, with tweaks like tightening the climate-risk disclosure obligations of corporations.

The government has also proposed a wide range of green measures in its new climate plan released in December — which the think tank called the “most ambitious” in Canada’s history — including energy retrofit programs, boosting hydrogen and other alternative fuels, and rolling out carbon capture technology in a grid where 18% of electricity still came from fossil fuels in 2019.

But the possible “three-year stimulus package to jumpstart our recovery” mentioned in the fall economic statement came with the caveat that the COVID-19 virus would have to be “under control.” While vaccines are being administered, Canada is currently dealing with a rise of highly transmissible variants of the virus.

Freeland spoke with United States Vice-President Kamala Harris on March 25, highlighting potential Canada-U.S. collaboration on EVs alongside the “need to support entrepreneurs, small businesses, young people, low-wage and racialized workers, the care economy, and women” in the context of an economic recovery.

Biden is contemplating a climate recovery plan that could exceed US$2 trillion as Canada looks to capitalize on the U.S. auto pivot to EVs to spur domestic industry. Per capita, that is over 8 times what Canada has announced so far for climate-related spending in the wake of the pandemic, according to a new analysis from green groups.
U.S. President Joe Biden is contemplating a climate and clean energy recovery plan that could “exceed US$2 trillion,” White House officials told reporters this month. “Per capita, that is over eight times what Canada has announced so far for climate-related spending in the wake of the pandemic,” the IISD-led analysis stated.

Biden’s election platform commitment of $508 billion over 10 years in clean energy was also seen as “significantly higher per capita than Canada’s recent commitments.”

Since October 2020, Canada has announced $36 billion in new climate-focused funding, a 2035 EV mandate and other measures, the groups found. By comparison, they noted, a political agreement in Europe proposed that a minimum of 37 per cent of investments in each national recovery plan should support climate action. France and Germany have also committed tens of billions of dollars to support clean hydrogen.

As for electric vehicles (EVs), the United Kingdom has committed $4.9 billion, while Germany has put up $7.5 billion to expand EV adoption and charging infrastructure and sweeten incentive programs for prospective buyers, complementing Canada’s ambitious EV goals announced domestically. The U.K. has also committed $3.5 billion for bike lanes and other active transportation, the groups noted.

Canada announced $400 million over five years this month for a new network of bike lanes, paths, trails and bridges, the first federal fund dedicated to active transportation.

Olympus Renewable Energy Initiative reduces CO2 emissions by sourcing 100% clean electricity at major Japan R&D and manufacturing sites, accelerating ESG goals toward net zero, decarbonization, and TCFD-aligned sustainability across global operations.

Key Points

Olympus's program to source renewable power, cut CO2, and reach net-zero site operations by 2030.

✅ 100% renewable electricity at major Japan R&D and manufacturing sites

✅ Expected 70% renewable share of electricity in FY2023

✅ Net-zero site operations targeted company-wide by 2030

Olympus Corporation announces that from April 2022, the company has begun to exclusively source 100% of the electricity used at its major R&D and manufacturing sites in Japan from renewable sources. As a result, CO2 emissions from Olympus Group facilities in Japan will be reduced by approximately 40,000 tons per year. The percentage of the Olympus Group's total electricity use in fiscal 2023 (ending March 2023) from renewable energy sources, including green hydrogen applications, is expected to substantially increase from approximately 14% in the previous fiscal year to approximately 70%.

Olympus has set a goal of achieving net zero CO2 emissions from its site operations by 2030, as part of its commitment to achieving environmentally responsible business growth and creating a sustainable society, aligning with Europe's push for electrification to address climate goals. This is a key goal in line with Olympus Corporation's ESG materiality targets focused on the theme of a "carbon neutral society and circular economy."

The company has already introduced a wide range of initiatives to reduce CO2 emissions. This includes the use of 100% renewable energy at some manufacturing sites in Europe, despite electricity price volatility in the region, and the United States, the installation of solar power generation facilities at some manufacturing sites in Japan, and support of the recommendations made by the Task Force on Climate-related Financial Disclosures (TCFD), alongside developments such as Honda's Ontario battery investment that signal rapid electrification.

To achieve its carbon neutral goal, Olympus will continue to optimize manufacturing processes and promote energy-saving measures, and notes that policy momentum from Canada's EV sales regulations and EPA emissions limits is accelerating complementary electrification trends, is committed to further accelerate the shift to renewable energy sources across the company, thereby contributing to the decarbonization of society on a global level, as reflected in regional labor markets like Ontario's EV jobs boom that accompany the transition.

Alberta Leads Canada’s Renewable Surge showcases how the province is transforming its power grid with wind, solar, and hydrogen energy projects that reduce carbon emissions, create sustainable jobs, and drive Canada’s clean electricity future.

Key Points: Alberta Leads Canada’s Renewable Surge

It is a national clean energy initiative showcasing Alberta’s leadership in renewable electricity generation, grid modernization, and sustainable economic growth.

✅ Expands solar, wind, and hydrogen projects across Alberta

✅ Reduces emissions while strengthening grid reliability

✅ Creates thousands of clean energy jobs and investments

Alberta is rapidly emerging as a national leader in clean electricity, driving Canada’s transition to a low-carbon energy future. A federal overview highlights how the province has become the powerhouse behind the country’s renewable energy growth across the Prairies, phasing out coal ahead of schedule and attracting billions in clean-energy investment.

In 2023, Alberta accounted for an astonishing 92 percent of Canada’s increase in renewable electricity generation, reflecting a renewable energy surge across the province. Solar and wind developments have expanded dramatically, as new lower-cost solar contracts are signed, reducing the province’s reliance on natural gas and cutting emissions from the power sector. Alberta’s vast land area and strong wind and solar resources have made it an ideal location for large-scale renewable projects that are transforming its energy landscape.

Federal programs are helping fuel this momentum. Through the Smart Renewables and Electrification Pathways program, 49 Alberta projects have already received over $660 million in funding, with an additional $152 million announced in the 2024 federal budget. Flagship developments include the Forty Mile Wind Farm and the Big Sky Solar Power Project, each backed by $25 million in federal support. These investments are creating jobs, strengthening grid reliability, and positioning Alberta at the forefront of Canada’s clean energy transition.

Although fossil fuels still dominate Alberta’s electricity mix, a major change is underway. In 2022, coal and natural gas accounted for 81 percent of electricity generation, while renewables and other sources contributed 18 percent, and the province’s hydroelectric capacity remained comparatively small. However, Alberta has successfully phased out coal generation ahead of the federal deadline, marking a milestone achievement in the province’s decarbonization journey.

Alberta’s renewable expansion features some of the country’s most significant projects. The Travers Solar Project in Vulcan County generates up to 465 megawatts — enough to power about 150,000 homes. Indigenous-led solar initiatives are also expanding, underscoring the province’s solar power growth, supported by $160 million in federal funding that has already created more than 1,500 jobs. On the wind side, the 494-megawatt Buffalo Plains Wind Farm, Canada’s largest onshore installation, began operating in 2024, followed by the 190-megawatt Paintearth Wind facility, which signed a 15-year power purchase agreement with Microsoft.

Beyond wind and solar, Alberta is exploring new technologies to maintain a stable, low-carbon grid while addressing solar expansion challenges related to grid integration. The province is collaborating with Saskatchewan on the development of small modular reactors (SMRs) to provide reliable baseload power and support the long-term shift toward net-zero electricity by 2050. Projects integrating carbon capture and storage are also moving forward, such as the proposed Moraine Power Generating Project — a 465-megawatt natural gas plant that is expected to create more than 700 jobs during construction.

The economic potential of Alberta’s clean energy transformation is substantial. Clean Energy Canada estimates that between 2025 and 2050, the province could gain more than 400,000 new jobs in the clean energy sector — triple the number currently employed in the upstream oil and gas industry. These positions will span renewable generation, hydrogen production, grid modernization, and energy storage.

With strong federal backing, aggressive private investment, and rapid deployment of renewable energy, Alberta is redefining its energy identity. Once known for its fossil fuel resources, the province is now positioning itself as a powerhouse for both green energy and fossil fuels in Canada, demonstrating that economic growth and environmental responsibility can go hand in hand.

EU Renewable Energy Transition accelerates as solar and wind overtake gas, cutting coal reliance and boosting REPowerEU goals; falling electricity demand, hydro and nuclear recovery, and grid upgrades drive a cleaner, secure power mix.

Key Points

It is the EU's shift to solar and wind, surpassing gas and curbing coal to meet REPowerEU targets.

✅ Solar and wind supplied 22% of EU electricity in 2022.

✅ Gas fell behind; coal stayed near 16% with no major rebound.

✅ Demand fell; hydro and nuclear expected to recover in 2023.

European countries were forced to accelerate their renewable energy capacity after Russia's invasion of Ukraine sparked a global energy crisis amid a surge in global power demand that exceeded pre-pandemic levels. The EU’s REPowerEU plan aims to increase the share of renewables in final energy consumption overall to 45 percent by the end of the decade.

However, a new report by energy think tank Ember shows that the EU’s green energy transition is already making a significant difference. Solar and wind power generated more than a fifth (22 percent) of its electricity in 2022, pulling ahead of fossil gas (20 percent) for the first time, according to the European Electricity Review 2023.

Europe also managed to avoid resorting to emissions-intensive coal power for electricity generation as a consequence of the energy crisis, even as renewables to eclipse coal globally by mid-decade. Coal generated just 16 percent of the EU’s electricity last year, an increase of just 1.5 percentage points.

“Europe has avoided the worst of the energy crisis,” says Ember’s Head of Data Insights, Dave Jones. “The shocks of 2022 only caused a minor ripple in coal power and a huge wave of support for renewables. Any fears of a coal rebound are now dead.”

Ember’s analysis reveals that the EU faced a "triple crisis" in the electricity sector in 2022, as stunted hydro and nuclear output compounded the shock. "Just as Europe scrambled to cut ties with its biggest supplier of fossil gas, it faced the lowest levels of hydro and nuclear (power) in at least two decades, which created a deficit equal to 7 percent of Europe’s total electricity demand in 2022," the report says. A severe drought across Europe, French nuclear outages as well as the closure of German nuclear outlets were responsible for the drop.

Solar power shines through
However, the record surge in solar and wind power generation helped compensate for the nuclear and hydropower deficit. Solar power rose the fastest, growing by a record 24 percent last year which almost doubled its previous record, with wind growing by 8.6 percent.

Forty-one gigawatts of solar power capacity was added in 2022, almost 50 percent more than the year before. Ember says that 20 EU countries achieved solar records in 2022, with Germany, Spain, Poland, the Netherlands and France adding the most solar capacity.

The Netherlands and Greece generated more power from solar than coal for the first time. Greece is also predicted to reach its 2030 solar capacity target by the end of this year.

EU electricity demand falls
A significant drop in electricity use in 2022 also helped lessen the impact of Europe’s energy crisis. Demand fell by 7.9 percent in the last quarter of the year, despite the continent heading into winter. This was close to the 9.6 percent fall experienced when Europe was in Covid-19 lockdown in mid-2020.

"Mild weather was a deciding factor, but affordability pressures likely played a role, alongside energy efficiency improvements and citizens acting in solidarity to cut energy demand in a time of crisis," the report says.

A ‘coal comeback’ fails to materialize
The almost 8 percent fall in electricity demand in the last three months of 2022 was the main factor in the 9 percent fall in gas and coal generation during that time. However, Ember says that had France’s nuclear plants been operating at the same capacity as 2021, the EU’s fossil fuel generation would have fallen twice as fast in the last quarter of 2022.

The report says: "Coal power in the EU fell in all four of the final months of 2022, down 6 percent year-on-year. The 26 coal units placed on emergency standby for winter ran at an average of just 18 percent capacity. Despite importing 22 million tonnes of extra coal throughout 2022, the EU only used a third of it."

Gas generation was very similar compared to 2021, up just 0.8 percent. It made up 20 percent of the EU electricity mix in 2022, up from 19 percent the year before.

Fossil fuel generation set to fall in 2023
Ember says low-emissions sources like solar and wind power will continue to accelerate in 2023 and hydropower and French nuclear capacity will also recover. With electricity demand likely to continue to fall, it estimates that fossil fuel-generation "could plummet" by 20 percent in 2023.

Gas generation will fall the fastest, Ember predicts, as it will remain more expensive than coal over the next few years. "The large fall in gas generation means the power sector is likely to be the fastest falling segment of gas demand during 2023, helping to bring calm to European gas markets as Europe adjusts to life without Russian gas."

In order to stick to the 2015 Paris Agreement target of limiting global warming to no more than 1.5 degrees Celsius compared to pre-industrial levels, Ember says Europe must fully decarbonize its power system by the mid-2030s. Its modeling shows that this is possible without compromising the security of supply.

However, the report says "making this vision a reality will require investment above and beyond existing plans, as well as immediate action to address barriers to the expansion of clean energy infrastructure. Such a mobilization would boost the European economy, cement the EU’s position as a climate leader and send a vital international message that these challenges can be overcome."

Canada Renewable Energy Partnerships advance wind power and clean electricity in Alberta and Saskatchewan, cutting emissions and supporting net-zero goals through Capital Power and SaskPower agreements with Indigenous participation and 25-year supply contracts.

Key Points

Government-backed deals with Capital Power and SaskPower to deliver clean electricity and reduce emissions.

✅ 25-year renewable supply for federal facilities

✅ New Halkirk 2 Wind project in Alberta

✅ Emissions cuts with Indigenous participation

The Government of Canada has partnered with two major energy providers in Western Canada (Prairie provinces) on renewable energy projects.

Tourism Minister Randy Boissonnault appeared in Edmonton on Friday to announce a new Alberta wind-generation facility in partnership with Capital Power.

It's one of two new energy partnerships in Western Canada as part of the 2030 emissions reduction plan by Public Services and Procurement Canada.

On Jan. 1, the federal government awarded a contract worth up to $500 million to Capital Power to provide all federal facilities in Alberta with renewable electricity as part of Alberta's renewable energy surge for 25 years.

"We're proud to partner with the government of Canada to help them reach their 100 per cent clean electricity by 2025 goal," said Jason Comandante, Capital Power vice president of commercial services.

The agreement also includes opportunities for Indigenous participation, including facility development partnerships and employment and training opportunities.

"At Capital Power, we are committed to net-zero by 2045, and are proud to take action against climate change. Collaborative agreements like this help support our net-zero goals, provide us opportunities to meaningfully engage Indigenous communities, and help decarbonize Alberta's power grid," Comandante said.

Capital Power will provide around 250,000 megawatt-hours of electricity each year through existing renewable energy credits while the new Capital Power Halkirk 2 Wind facility is being developed.

Located near Paintearth, Alta., the proposed wind farm will have up to 35 turbines and generate enough power for the average yearly electricity needs of more than 70,000 Alberta homes.

The project is currently awaiting regulatory approval, within Alberta's energy landscape, with construction projected to begin this summer. When complete, it will supply 49 per cent of its output to the federal government.

"Through the agreement, the federal government is supporting the ongoing development of renewable energy infrastructure development within the province," Boissonnault said.

The new partnership will join another in Saskatchewan and complement Alberta solar facilities that have been contracted at lower cost than natural gas.

In 2022, the federal government signed an agreement with SaskPower to supply clean electricity to the approximately 600 federal facilities in Saskatchewan. That wind project is expected to come online by 2024.

Boissonnault said the two initiatives combined will reduce carbon dioxide emissions in Alberta and Saskatchewan by about 166 kilotonnes.

"That is the equivalent of the emissions from more than 50,000 cars driven for one year. So, if you think about that, that's a great reduction right here in Alberta and Saskatchewan," he said.

"These are concrete steps to ensuring that Canada remains a leader of renewable energy on the global stage and grid modernization projects to help the fight against climate change."
