"World?s Most Powerful? Tidal Turbine Starts Pumping Green Electricity To Onshore Grid

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.

BC Hydro Vehicle-to-Grid Pilot enables EVs to deliver V2G power, using bidirectional charging to provide grid services, clean energy resilience, and emergency power for microgrids, critical infrastructure, and storm response.

Key Points

BC Hydro's V2G pilot uses parked EVs as mobile batteries, supplying bidirectional power to the grid for resilience.

✅ Medium- and heavy-duty EV integration via 60 kW charger

✅ Supports critical infrastructure and storm response

✅ Cleaner, faster alternative to diesel generators

BC Hydro has unveiled an innovative pilot project designed to enable electric vehicles (EVs) to contribute electricity back to the power grid, with some owners able to sell electricity back to the grid through managed programs, effectively transforming these vehicles into mobile energy storage units that function as capacity on wheels for the electricity system.

The utility company recently announced the successful trial of the vehicle-to-grid program, allowing for the transfer of electricity from the batteries of medium- and heavy-duty EVs back to the electrical grid. This surplus electricity can be utilized in various ways, including supporting emergency response efforts by energizing critical infrastructure and to power buildings during natural disasters or major storms. It offers a cleaner, faster, and more flexible alternative to conventional methods like the use of diesel generators.

BC Hydro's President and CEO, Chris O'Riley, highlighted the significance of this initiative, stating, "The average car is parked 95 per cent of the time, and with the evolution of technology solutions like vehicle-to-grid, stationary vehicles hold the potential to become mobile batteries, powered by clean and affordable electricity."

The successful test was conducted using a Lion Electric school bus provided by Lynch Bus Lines, which was connected to a 60-kilowatt charger, illustrating BC Hydro's rollout of faster electric vehicle charging across the province. BC Hydro pointed out that the typical bus battery holds 66 kilowatts of electricity, sufficient to power 24 single-family homes with electric heating for two hours. Therefore, if 1,000 of these buses were converted to electric power, they could collectively supply electricity to 24,000 homes for two hours.

This groundbreaking project is a collaborative effort between BC Hydro, Powertech, and Coast to Coast Experience, with funding support from the provincial government amid study findings that B.C. may need to double its power output to meet transport electrification.

While this pilot marks the first of its kind in Canada, similar technology has already been successfully implemented in Europe and the United States, including California's efforts to leverage EVs for grid stability that offer promising potential for enhancing the energy landscape and sustainability in the region.

Separately, Nova Scotia Power plans to pilot electric vehicle to grid integration in Atlantic Canada, underscoring growing national interest in V2G approaches.

U.S. Renewable Energy Record 28% signals a cleaner power grid as wind, solar, and hydroelectric output soar; EIA data shows cost-competitive clean energy reshaping the electricity mix and reducing carbon emissions across regions.

Key Points

EIA-reported April share of electricity from wind, solar, and hydro, reflecting cost-driven growth in U.S. clean power.

✅ Wind, solar additions dominated recent U.S. capacity buildouts

✅ Lower levelized costs make renewables most competitive

✅ Seasonal factors and outages lowered fossil and nuclear output

The amount of electricity generated by renewable resources hit a record 28% in April, a breakthrough number that shows how important renewable energy has become in U.S. energy markets as it surpassed coal in 2022 overall.

"It's a 'Wow' moment," said Peter Kelly-Detwiler, an energy analyst and author of "The Energy Switch," a recent book about the transition to a carbon-free energy economy.

The percentage of U.S. electricity produced by renewable energy from wind, solar and hydroelectric dams has been steadily rising, from 8.6% in April 2001 to this April's 28%. Those numbers were released this week by the U.S. Energy Information Administration, which tracks energy data for the nation.

What explains the surge?
There are several reasons. At the top is that wind and solar installations dominated U.S. energy buildouts.

"Basically, the only things we've added to the grid in the past decade are wind, solar and natural gas," said Harrison Fell, an economist and engineer at Columbia University, where he co-leads the Power Sector and Renewables Research Initiative.

That's happening for two reasons. The first is cost. Renewables are simply the most economically competitive power currently available, Kelly-Detwiler said.

In 2021, the cost of producing a megawatt-hour of electricity from a new wind turbine was $26 to $50. The same amount of electricity from the cheapest type of natural gas plant ranged from $45 to $74, according to Lazard, a financial advisory firm that publishes annual estimates of the cost of producing electricity. 

Federal and state mandates and incentives to increase the amount of clean energy used also help, Fell said, as renewables reached 25.5% of U.S. electricity recently. 

"When you do the math on what's the most profitable thing to add, it's often going to be wind and solar at this stage," he said.

Was weather a factor?
Yes. April tends to be a particularly windy month, and this spring was windier than most, Fell said.

There's also less power coming into the grid from fossil fuels and nuclear in the spring. That's because electricity demand is generally lower because of the mild weather and fossil fuel and nuclear power plants use the time for maintenance and refueling, which reduces their production, he said.

Another surprise was that in April, wind and solar power together produced more electricity than nuclear plants nationwide. 

Historically, nuclear power plants, which are carbon-neutral, have reliably produced about 20% of America's electricity. In April that number dropped to 18% while wind and solar combined stood at 19.6%.

The nuclear decrease is partly a result of the shutdown of two plants in the past year, Indian Point in New York state and Palisades in Michigan, as well as scheduled closures for maintenance.

Will the trend continue?
When all U.S. carbon-neutral energy sources are added together – nuclear, wind, hydroelectric and solar – almost 46% of U.S. electricity in April came from sources that don't contribute greenhouse gases to the environment, federal data shows.  

"It's a milestone," Kelly-Detwiler said. "But in a few years, we'll look back and say, 'This was a nice steppingstone to the next 'Wow!' moment."

Peak Power V1G EV chargers optimize smart charging in Ontario, using Synergy technology and ZEVIP support to manage peak demand, enhance grid capacity, and expand EV infrastructure across mixed-use developments with utility-friendly energy management.

Key Points

Peak Power's V1G smart chargers use Synergy tech to cut peak load and grow Ontario EV charging access.

✅ 117 chargers funded by NRCAN's ZEVIP program

✅ Synergy tech shifts load off peak to boost grid capacity

✅ Partners: SWTCH Energy and Signature Electric

Peak Power, a Canadian climate tech company with a core focus in energy management and energy storage, announces it has received a $765,000 investment through Natural Resources Canada’s (NRCan) Zero Emission Vehicle Infrastructure Program (ZEVIP) to install 117 V1G chargers as Ontario energy storage push intensifies province-wide planning. The total cost of the project is valued at over $1.6 million.

Peak Power will install the V1G chargers across several mixed-use developments in Ontario. Peak Power’s Synergy technology, which is currently used in the company’s successful Peak Drive EV charging project, will underpin the chargers. The Synergy tech will enable the chargers to draw energy from the grid when it’s most widely available and avoid times of peak demand, similar to emerging EV-to-grid integration pilots now, and can also adjust the flow rate at which the cars are charged. The intelligent chargers will reduce strain on the grid, benefiting utilities and electricity users by increasing grid capacity as well as giving EV drivers more locations to charge their vehicles.

As part of ZEVIP, the project supports the federal government’s goals of accelerating the electrification of Canada’s transportation sector. The 117 chargers will encourage adoption of EVs, as drivers have access to expanded infrastructure for charging, and as Ontario streamlines charging-station builds to accelerate deployments. From the perspective of grid operators, the intelligent nature of the Peak Power software will allow more capacity from the grid without requiring major infrastructure upgrades.

Peak Power will work with partners with deep expertise in EV charging to install the chargers. SWTCH Energy is co-developing the software for the EV chargers with Peak Power, while Signature Electric will install the hardware and supporting infrastructure.

“We’re thrilled to support the Canadian government's electrification goals through smart EV charging,” said Matthew Sachs, COO of Peak Power. “The funding from NRCan will enable us to provide drivers with more options for EV charging, while the smart nature of our Synergy tech in the chargers means grid operators don’t have to worry about capacity restraints when EVs are plugged into the grid, with EV owners selling power back offering additional flexibility too. ZEVIP is critical to greater electrification of the country’s infrastructure, and we’re proud to support the initiative.”

“Happy EV Week, Canada. Our government is making electric vehicles more affordable and charging more accessible where Canadians live, work and play, for example through the Ivy and ONroute charging network that supports travel corridors,” said the Honourable Jonathan Wilkinson, Minister of Natural Resources. “Investing in more EV chargers, like the ones announced today in Ontario, will put more Canadians in the driver’s seat on the road to a net-zero future and help achieve our climate goals.”

"I'm pleased to be announcing the deployment of over 100 Electric Vehicle chargers across Ontario with Peak Power,” said Julie Dabrusin, Parliamentary Secretary to the Minister of Natural Resources and to the Minister of Environment and Climate Change, and Member of Parliament for Toronto-Danforth. “This $765,000 investment by the Government of Canada will allow folks in Toronto and across the province to access the infrastructure they need, as B.C. expands EV charging shows national momentum, to drive an EV while fighting climate change. Happy #EVWeek!”

"Limited access to EV charging infrastructure in high-density mixed-used environments remains a key barrier to widespread EV adoption,” said Carter Li, CEO of SWTCH. “SWTCH’s partnership with Peak Power and Signature Electric to deploy V1G technology to these settings will enhance coordination between energy utilities, building operators, and EV drivers to improve building energy efficiency and access to EV charging infrastructure, with charger rebates in B.C. expanding home and workplace options as well.”

“Signature Electric is proud to be a partner on increasing the availability of localized charging for Canadians,” said Mark Marmer, Owner of Signature Electric. “Together, we can scale EV infrastructure to support Canada’s commitment to achieving net-zero emissions by 2050.”

B.C. EV Bottleneck signals a post-pandemic demand surge for electric vehicles amid semiconductor and lithium-ion battery shortages, driving waitlists, record sales, rebates, charging infrastructure needs, and savings on fuel and maintenance across British Columbia.

Key Points

B.C. EV bottleneck is rising demand outpacing supply from chip and battery shortages, creating waitlists.

✅ 85% delayed EV purchase; demand rebounds with reopening.

✅ Supply chain limits: chips and lithium-ion batteries.

✅ Plan ahead: join waitlists, consider used EVs, claim rebates.

B.C. Hydro is warning of a post-pandemic “EV bottleneck” as it predicts pent-up demand and EV shortages will lead to record-breaking sales for electric vehicles in 2021.

A new survey by B.C. Hydro found 85 per cent of British Columbians put off buying an electric vehicle during the pandemic, but as the province reopens, the number of people on the road commuting to-and-from work and school is expected to rise 15 per cent compared with before the pandemic.

It found about two-thirds of British Columbians are considering buying an EV over the next five years, with 60 per cent saying they would go with an EV if they can get one sooner.

“The EV market is at a potential tipping point, as demand is on the rise and will likely continue to grow long-term, with one study projecting doubling power output to meet full road electrification,” said a report about the findings released Wednesday.

The demand for EVs is prompted by rising gas prices, environmental concerns and to save money on maintenance costs like oil changes and engine repairs, said the report. At the same time, a shortage of semiconductor chips and lithium ion batteries needed for auto production is squeezing supply.

For people wanting to make the switch to electric, B.C. Hydro recommended they plan ahead and get on several waiting lists and explore networks offering faster charging options. Used EVs are also a cheaper option.

B.C. Hydro said an electric vehicle can save 80 per cent in gas expenses over a year and about $100 a month in maintenance costs compared with a gas-powered vehicle. There are also provincial and federal rebates of up to $8,000 for EV purchases in B.C., and additional charger rebates can help with installation costs.

B.C. has the highest electric vehicle uptake in North America, with zero-emission vehicles making up almost 10 per cent of all car sales in the province in 2020 as the province expands EV charging to support growth — more than double the four per cent in 2018.

According to a report by University of B.C. business Prof. Werner Antweiler on the state of EV adoption in B.C., electric vehicles are still concentrated in urban areas like Metro Vancouver and the Capital Regional District on Vancouver Island where public charging stations are more readily available.

He said electric vehicle purchases are still hampered by limited choice and a lack of charging stations, especially for people who park on the street or in condo parkades, which would require permission from strata councils to install a charging station, though rebates for home and workplace charging can ease installation.

The online survey was conducted by market researcher Majid Khoury of 800 British Columbians from May 17-19. It has a margin of error of plus-or-minus 3.5 per cent, 19 times out of 20.

New York BESS advance renewable energy storage, boosting grid reliability and resilience with utility-scale projects, strict safety oversight, and NYPA leadership to meet 6,000 MW by 2030 and 1,500 MW by 2035 targets.

Key Points

New York BESS are battery storage projects that balance the grid, enable renewables, and meet strict safety rules.

✅ State targets: 6,000 MW by 2030; 1,500 MW by 2035.

✅ NYPA 20-MW project eases congestion, boosts reliability.

✅ FDNY, NYC DOB, and state agencies enforce stringent safety rules.

In the evolving landscape of renewable energy, New York State is making significant advancements through the deployment of Battery Energy Storage Systems (BESS), a trend mirrored by Ontario's plan to rely on battery storage to meet rising demand today. These systems are becoming a crucial component in the shift towards a more sustainable and clean energy future, by providing a solution to one of renewable energy's most significant challenges: storage.

BESS plays a critical role in bridging the gap between energy generation and consumption, and many utilities see benefits in energy storage across their systems today, too. During periods of surplus generation, such as sunny or windy conditions conducive to solar and wind power production, BESS captures and stores excess electricity. This stored energy can then be released back into the grid during times of high demand or when generation is low, ensuring a consistent and reliable energy supply.

Governor Kathy Hochul's administration has been proactive in harnessing this technology. In a landmark move, the state inaugurated its first state-owned, utility-scale BESS facility in Franklin County's Chateaugay, and similar utility procurements, such as SDG&E's Emerald Storage solution, underscore market momentum, signifying a major step towards bolstering New York's BESS infrastructure. This facility, featuring five large enclosures each housing over 19,500 batteries, signifies the beginning of New York's ambitious journey towards expanding its BESS capabilities.

Environmental advocates, including the New York League of Conservation Voters, have lauded these developments, viewing them as essential to meeting New York's climate goals, and they point to community-scale deployments such as a Brooklyn low-income housing microgrid as tangible examples of equitable resilience, too. Currently, New York's BESS capacity stands at approximately 291 megawatts. However, Governor Hochul has set forth bold targets to escalate this capacity to 1,500 megawatts by 2035 and even more ambitiously, to 6,000 megawatts by 2030. Achieving these targets would enable the powering of 1.2 million homes with clean, renewable energy.

"Battery storage is pivotal for the reliability of our electric grid and for the phasing out of pollutive power plants that harm our communities," remarked Pat McClellan, NYLCV’s Policy Director. The implementation of BESS is deemed vital for New York to attain its statutory climate mandates, including achieving 70 percent renewable energy by 2030 and 100 percent clean energy by 2040.

Safety and regulatory oversight are paramount in the proliferation of BESS facilities, especially in densely populated areas like New York City. The state has introduced stringent regulations, overseen by both the NYC Fire Department and the NYC Buildings Department, with state and federal governments also playing a crucial role in ensuring the safe deployment of these technologies, and best practices from jurisdictions focused on enabling storage in Ontario's electricity system can inform ongoing refinements as well.

In a significant announcement last August, Governor Hochul underscored the necessity of state oversight on BESS safety issues. She announced the formation of a new Inter-Agency Fire Safety Working Group tasked with examining energy storage facility fires and safety standards. This group, comprising six state agencies, recently unveiled its findings and recommendations, which will undergo public review.

Governor Hochul emphasized, "The battery energy storage industry is pivotal for communities across New York to transition to a clean energy future, and comprehensive safety standards are critical." The state's proactive stance on adopting these recommendations aims to safeguard New York’s transition to clean energy.

The completion of the Northern New York Energy Storage Project, a 20-MW facility operated by the New York Power Authority, marks a significant milestone in New York's clean energy journey. This project, aimed at alleviating transmission congestion and enhancing grid reliability, serves as a model for integrating clean energy, especially during peak demand periods, as other regions, such as Ontario, are plunging into energy storage to address looming supply crunches.

Located in a region where over 80% of electricity is generated from renewable sources, this project not only supports the state's clean energy grid but also accelerates New York's energy storage and climate objectives. Governor Hochul expressed, “Deploying energy storage technologies enhances our power supply's reliability and resilience, further enabling New York to construct a robust clean energy grid.”

As New York State advances towards its ambitious energy storage and climate goals, the development and deployment of BESS are critical. These systems not only enhance grid reliability and resilience but also support the broader transition to renewable energy sources, including emerging long-duration storage projects that expand flexibility, marking an essential step in New York's commitment to a sustainable and clean energy future.
