Bus depot bid to be UK's largest electric vehicle charging hub

UK electric vehicle sales reached a record high in September, with battery and hybrid cars making up over half of new registrations. SMMT credits carmaker discounts, new models, and a £3,750 EV grant for driving strong demand across the UK market.

Why are UK Electric Vehicle Sales Surging to a Record High?

UK electric vehicle sales are surging to a record high because automakers are offering major discounts, more models are available than ever, and the government’s new £3,750 EV grant is making electric cars more affordable and appealing to both fleets and private buyers.

✅ BEV sales up nearly one-third in September

✅ Over half of all new cars are now electrified

✅ £3,750 EV grants boost consumer confidence

Electric vehicle (EV) sales in the United Kingdom reached a record high last month, marking a significant milestone in the country’s transition to cleaner transportation. According to the latest figures from the Society of Motor Manufacturers and Traders (SMMT), sales of pure battery electric vehicles (BEVs) surged by nearly one-third to 72,779 units in September, while plug-in hybrid registrations grew even faster.

The combined total of fully electric and hybrid vehicles accounted for more than half of all new car registrations, underscoring the growing appeal of electrified transport, alongside global EV market growth, among both businesses and private consumers. In total, 312,887 new vehicles were registered across the country — the strongest September performance since 2020, according to SMMT data.

SMMT chief executive Mike Hawes said the surge in electrified vehicle sales showed that “electrified vehicles are powering market growth after a sluggish summer.” He credited carmaker incentives, a wider choice of models, and government support for helping accelerate adoption, though U.S. EV market share dipped in Q1 2024 by comparison. “Industry investment in electric vehicles is paying off,” Hawes added, even as he acknowledged that “consumer demand still trails ambition.”

The UK government’s new electric car grant scheme has played a significant role in the rebound. The program offers buyers discounts of up to £3,750 on eligible EVs priced under £37,000. So far, more than 20,000 motorists have benefited, with 36 models approved for reductions of at least £1,500. Participating manufacturers include Ford, Toyota, Vauxhall, and Citroën.

Ian Plummer, chief commercial officer at Autotrader, said the grant had given a “real lift to the market,” echoing fuel-crisis EV inquiry surge in the UK. He noted that “since July, enquiries for new electric vehicles on Autotrader are up by almost 50%. For models eligible for the grant, interest has more than doubled.”

While the majority of BEVs — about 71.4% — were purchased by companies and fleets, the number of private buyers has also been increasing. Zero-emission vehicles now account for more than one in five (22.1%) new car registrations so far in 2025, similar to France’s 20% EV share record, highlighting the growing mainstream appeal of electric mobility.

The surge comes amid a challenging backdrop for the automotive sector, even as U.S. EV sales soared into 2024 across the Atlantic. The UK car industry is still reeling from the effects of US trade tariffs and recent disruptions, such as Jaguar Land Rover’s production shutdown following a cyberattack. Despite these hurdles, the strong September figures have boosted confidence in the industry’s recovery trajectory, and EU EV share grew during lockdown months offers precedent for resilience.

Among individual models, the Kia Sportage, Ford Puma, and Nissan Qashqai led overall sales, while two Chinese vehicles — the Jaecoo 7 and BYD Seal U — entered the top ten, reflecting China’s growing footprint in the UK market. Analysts say the arrival of competitively priced Chinese EVs could further intensify competition and drive prices lower for consumers.

With electrified vehicles now dominating new registrations and fresh government incentives in place, industry observers believe the UK is gaining momentum toward its long-term net-zero goals. The challenge, however, remains converting business fleet enthusiasm into sustained private-buyer confidence through affordable models, with UK consumer price concerns still a factor, reliable charging infrastructure, and continued policy support.

Harbour Air Electric Aircraft Project advances zero-emission aviation with CleanBC Go Electric ARC funding, converting seaplanes to battery-electric power, cutting emissions, enabling commercial passenger service, and creating skilled clean-tech jobs through R&D and electrification.

Key Points

Harbour Air's project electrifies seaplanes with CleanBC ARC support to enable zero-emission flights and cut emissions.

✅ $1.6M CleanBC ARC funds seaplane electrification retrofit

✅ Target: passenger-ready, zero-emission commercial service

✅ Creates 21 full-time clean-tech jobs in British Columbia

B.C.’s Harbour Air Seaplanes is building on its work in clean technology to decarbonize aviation, part of an aviation revolution underway, and create new jobs with support from the CleanBC Go Electric Advanced Research and Commercialization (ARC) program.

”Harbour Air is decarbonizing aviation and elevating the company to new altitudes as a clean-technology leader in B.C.'s transportation sector,” said Bruce Ralston, Minister of Energy, Mines and Low Carbon Innovation. “With support from our CleanBC Go Electric ARC program, Harbour Air's project not only supports our emission-reduction goals, but also creates good-paying clean-tech jobs, exemplifying the opportunities in the low-carbon economy.”

Harbour Air is receiving almost $1.6 million from the CleanBC Go Electric ARC program for its aircraft electrification project. The funding supports Harbour Air’s conversion of an existing aircraft to be fully electric-powered and builds on its successful December 2019 flight of the world’s first all-electric commercial aircraft, and subsequent first point-to-point electric flight milestones.

That flight marked the start of the third era in aviation: the electric age. Harbour Air is working on a new design of the electric motor installation and battery systems to gain efficiencies that will allow carrying commercial passengers, as it eyes first electric passenger flights in 2023. Approximately 21 full-time jobs will be created and sustained by the project.

“CleanBC is helping accelerate world-leading clean technology and innovation at Harbour Air that supports good jobs for people in our communities,” said George Heyman, Minister of Environment and Climate Change Strategy. “Once proven, the technology supports a switch from fossil fuels to advanced electric technology, and will provide a clean transportation option, such as electric ferries, that reduces pollution and shows the way forward for others in the sector.”

Harbour Air is a leader in clean-technology adoption. The company has also purchased a fully electric, zero-emission passenger shuttle bus to pick up and drop off passengers between Harbour Air’s downtown Vancouver and Richmond locations, and the Vancouver International Airport, where new EV chargers support travellers.

“It is great to see the Province stepping up to support innovation,” said Greg McDougall, Harbour Air CEO and ePlane test pilot. “This type of funding confirms the importance of encouraging companies in all sectors to focus on what they can be doing to look at more sustainable practices. We will use these resources to continue to develop and lead the transportation industry around the world in all-electric aviation.”

In total, $8.18 million is being distributed to 18 projects from the second round of CleanBC Go Electric ARC program funding. Recipients include Damon Motors and IRDI System, both based on the Lower Mainland. The 15 other successful projects will be announced this year.

The CleanBC Go Electric ARC program supports the electric vehicle (EV) sector in B.C., which leads the country in going electric, by providing reliable and targeted support for research and development, commercialization and demonstration of B.C.-based EV technologies, services and products.

“This project is a great example of the type of leading-edge innovation and tech advancements happening in our province,” said Brenda Bailey, Parliamentary Secretary for Technology and Innovation. “By further supporting the development of the first all-electric commercial aircraft, we are solidifying our position as world leaders in innovation and using technology to change what is possible.”

The CleanBC Roadmap to 2030 is B.C.’s plan to expand and accelerate climate action, including a major hydrogen project, building on the province’s natural advantages – abundant, clean electricity, high-value natural resources and a highly skilled workforce. It sets a path for increased collaboration to build a British Columbia that works for everyone.

Condo EV charging retrofits face strata approval thresholds, installation costs, and limited electrical capacity, but government rebates, subsidies, and smart billing systems can improve ROI, property value, and feasibility amid electrician shortages and infrastructure constraints.

Key Points

Condo EV charging retrofits equip multiunit parking with EV chargers, balancing costs, bylaws, capacity, and rebates.

✅ Requires owner approval (e.g., 75% in B.C.) and clear bylaws

✅ Leverage rebates, subsidies, and load management to cut costs

✅ Plan billing, capacity, and phased installation to increase ROI

Retrofitting an existing multiunit residential building with electric vehicle charging stations is a complex and costly exercise, as high-rise EV charging challenges in MURBs demonstrate, even after subsidies, but the biggest hurdle to adoption may be getting enough condo owners on board.

British Columbia, for example, offers a range of provincial government subsidies to help condo corporations (referred to in B.C. as stratas) with everything from the initial research to installing the chargers. But according to provincial strata law, three-quarters of owners must support the plan before it is implemented, though new strata EV legislation could make approvals easier in some jurisdictions.

“The largest challenge is getting that 75-per-cent majority approval to go ahead,” says EV charging specialist Patrick Breuer with ChargeFwd Ltd., a Vancouver-based sustainable transport consultancy.

Chris Brunner, a strata president in Vancouver, recently upgraded all the building’s parking stalls for EV charging. His biggest challenge was getting the strata’s investment owners, who don’t live in the building and were not interested in spending money, to support the project.

“We had to sell it in two ways,” Mr. Brunner says. “First, that there’s going to be a return on investment, including vehicle-to-building benefits that support savings and grid stability, and second, that there will come a time when this will be required. And if we do it now, taking advantage of the generous rebates and avoiding price increases for expertise and materials, we’ll be ahead of the curve.”

Once the owners have voted in favour, the condo board can begin the planning process and start looking for rebates. The B.C. government will provide a rebate of up to 75 per cent for the consulting phase, with additional provincial rebates available through current programs. It’s referred to as an “EV Ready” plan, which is a professionally prepared document that describes how to implement EV charging fairly, and estimates its cost.

Once a condo has completed the EV Ready plan, it becomes eligible for other rebates, such as the EV Ready Infrastructure subsidy, which will bring power to each individual parking stall through an energized outlet. This is rebated at 50 per cent of expenses, up to $600 a stall.

There are further rebates of up to 75 per cent for installing the charging stations themselves, and B.C. charging rebates extend to home and workplace programs, too. The program is administered by BC Hydro, a Crown corporation that receives funding in annual increments. “Right now, it’s funded until March 31, 2023,” Mr. Breuer says.

“Realtors are valuing [individual charging stations] from $2,000 to $10,000,” he said. The demand for installing EV chargers in buildings has grown to such an extent that it’s hard to find qualified electricians, Mr. Breuer says.

However, even with subsidies, there are some buildings where it doesn’t make financial sense to retrofit them. “If you have to core through thin floors or there’s a big parkade with a large voltage drop, it isn’t financially viable,” Mr. Breuer says. “We do a lot of EV Ready plans, but not all the projects can go ahead.”

For many people, it’s resistance to the unknown that is preventing them from voting for the retrofit, according to Carter Li of Toronto-based Swtch Energy Inc., which provides charging in high-density urban settings. It has done retrofits on 200 multiunit residential buildings in the Toronto area, and Calgary condo charging efforts show similar momentum in other cities, too. “They’re worried about paying for someone else’s electricity,” he says. Selling owners on the idea requires educating them about how the billing will work, maximizing electrical capacity to keep costs down, using government subsidies and the anticipated boost in property value.

Ontario currently does not provide any subsidies for retrofitting condos for EV charging. However, there is a stipulation under the Condominium Act that if owners request EV charging be installed and provide a condo board with sufficient documentation, an assessment will be conducted.

When Jeremy Benning was on the board of his Toronto condo in 2018, a few residents inquired about installing EV charging. A committee of owners did the legwork, and found a company that could do the infrastructure installation as well as set up accounts for individual billing purposes. Residents were surveyed a number of times before going ahead with the installation.

Mr. Benning estimates it cost about $40,000 to install two electrical subpanels to accommodate EV chargers in 20 parking spaces. Although the condo corporation paid the money up front out of its operating budget, everyone who ordered a charger will pay back their share over time. Many who do not even own an EV have opted to add a valuable frill to their unit.

The board considered applying for a subsidy from Natural Resources Canada, but it would require a public charger in the visitor parking lot. “The rebate wasn’t enough to pay for the cost of putting in that charging station,” Mr. Benning says. “Also, you have to maintain it, and what if it gets vandalized? It wasn’t worth it.”

Quebec’s Roulez Vert (Ride Green) program offers extensive provincial rebates and incentives for retrofitting condo buildings. If a single condo owner wants to install an EV charger, the government will refund up to 50 per cent of the installation cost or up to $5,000, whichever is less.

Otherwise, a property manager can qualify for a maximum of $25,000 a year to retrofit a building and can sometimes complete the work in stages. “They may do the first installation in one year, and then continue the next year,” says Léo Viger-Bernard of Recharge Véhicule Électrique (RVE). Recently, the Quebec government confirmed this program will run until 2027.

RVE consults with condo corporations, operates an online platform (murby.com) with resources for building owners, and sells a demand charge controller (DCC), which is an electric vehicle energy management system. The DCC allows an electrician to plug the EV charger directly into the electrical infrastructure of a single condo or apartment unit. Not only does this reduce extra wiring, but it also monitors the electrical consumption in each unit, only powering the charging station when there’s available electricity. Billing is assigned to the actual unit’s electricity bill.

Currently there are about 12,000 DCC units installed in retrofitted buildings across Canada, some that are 40 or 50 years old. “It’s not a question of age; it’s more the location of the electric meters,” Mr. Viger-Bernard says. The DCC can be installed either on the roof or on different floors.

According to Michael Wilk, president of Montreal-based Wilkar Property Management Inc., the biggest barrier is getting condo owners to understand the necessity of doing a retrofit now, as opposed to waiting. He uses price increases to try to convince them.

“Right now, the cost of doing a retrofit is 35 per cent more than it was two years ago,” he says. “If you wait another two years, we can only anticipate it’s going to be 35 per cent higher because of the rising cost of labour, parts and equipment.”

In Nova Scotia, Marc MacDonald of Spark Power Corp. installed an EV charger with a DCC unit at a condo near Halifax about a year ago. “They only had space in their electrical room to add a device for up to 10 EV chargers,” he says. The condo board was hesitant, demanding a great deal of information. “They were concerned about everyone wanting an EV charger.”

Now that Nova Scotia has introduced a program for rebates and incentives to install EV chargers in condos, on-street sites and more, Mr. MacDonald anticipates demand will increase, though Atlantic EV adoption still lags the national average. “But they’ll have to settle with reality. Not everyone can have an EV charger if the building can’t accommodate it.”

IEA World Energy Outlook 2020 highlights solar power as the cheapest electricity, projects faster renewables growth, models net-zero pathways, assesses COVID-19 impacts, oil and gas demand, and policy scenarios including STEPS, SDS, and NZE2050.

Key Points

A flagship IEA report analyzing energy trends, COVID-19 impacts, renewables growth, and pathways to net-zero in 2050.

✅ Solar now the cheapest electricity in most major markets

✅ Scenarios: STEPS, SDS, NZE2050, plus delayed recovery case

✅ Oil and gas demand uncertain; CO2 peak needs stronger policy

The world’s best solar power schemes now offer the “cheapest…electricity in history” with the technology cheaper than coal and gas in most major countries.

That is according to the International Energy Agency’s World Energy Outlook 2020. The 464-page outlook, published today by the IEA, also outlines the “extraordinarily turbulent” impact of coronavirus and the “highly uncertain” future of global energy use and progress in the global energy transition over the next two decades.

Reflecting this uncertainty, this year’s version of the highly influential annual outlook offers four “pathways” to 2040, all of which see a major rise in renewables across markets. The IEA’s main scenario has 43% more solar output by 2040 than it expected in 2018, partly due to detailed new analysis showing that solar power is 20-50% cheaper than thought.

Despite a more rapid rise for renewables and a “structural” decline for coal, the IEA says it is too soon to declare a peak in global oil use, unless there is stronger climate action. Similarly, it says demand for gas could rise 30% by 2040, unless the policy response to global warming steps up.

This means that, while global CO2 emissions have effectively peaked flatlining in 2019 according to the IEA, they are “far from the immediate peak and decline” needed to stabilise the climate. The IEA says achieving net-zero emissions will require “unprecedented” efforts from every part of the global economy, not just the power sector.

For the first time, the IEA includes detailed modeling of a 1.5C pathway that reaches global net-zero CO2 emissions by 2050. It says individual behaviour change, such as working from home “three days a week”, would play an “essential” role in reaching this new “net-zero emissions by 2050 case” (NZE2050).

Future scenarios
The IEA’s annual World Energy Outlook (WEO) arrives every autumn and contains some of the most detailed and heavily scrutinised analysis of the global energy system. Over hundreds of densely packed pages, it draws on thousands of datapoints and the IEA’s World Energy Model.

The outlook includes several different scenarios, to reflect uncertainty over the many decisions that will affect the future path of the global economy, as well as the route taken out of the coronavirus crisis during the “critical” next decade. The WEO also aims to inform policymakers by showing how their plans would need to change if they want to shift onto a more sustainable path, including creating the right clean electricity investment incentives to accelerate progress.

This year it omits the “current policies scenario” (CPS), which usually “provides a baseline…by outlining a future in which no new policies are added to those already in place”. This is because “[i]t is difficult to imagine this ‘business as-usual’ approach prevailing in today’s circumstances”.

Those circumstances are the unprecedented fallout from the coronavirus pandemic, which remains highly uncertain as to its depth and duration. The crisis is expected to cause a dramatic decline in global energy demand in 2020, with oil demand also dropping sharply as fossil fuels took the biggest hit.

The main WEO pathway is again the “stated policies scenario” (STEPS, formerly NPS). This shows the impact of government pledges to go beyond the current policy baseline. Crucially, however, the IEA makes its own assessment of whether governments are credibly following through on their targets.

The report explains:

“The STEPS is designed to take a detailed and dispassionate look at the policies that are either in place or announced in different parts of the energy sector. It takes into account long-term energy and climate targets only to the extent that they are backed up by specific policies and measures. In doing so, it holds up a mirror to the plans of today’s policy makers and illustrates their consequences, without second-guessing how these plans might change in future.”

The outlook then shows how plans would need to change to plot a more sustainable path, highlighting efforts to replace fossil fuels with electricity in time to meet climate goals. It says its “sustainable development scenario” (SDS) is “fully aligned” with the Paris target of holding warming “well-below 2C…and pursuing efforts to limit [it] to 1.5C”. (This interpretation is disputed.)

The SDS sees CO2 emissions reach net-zero by 2070 and gives a 50% chance of holding warming to 1.65C, with the potential to stay below 1.5C if negative emissions are used at scale.

The IEA has not previously set out a detailed pathway to staying below 1.5C with 50% probability, with last year’s outlook only offering background analysis and some broad paragraphs of narrative.

For the first time this year, the WEO has “detailed modelling” of a “net-zero emissions by 2050 case” (NZE2050). This shows what would need to happen for CO2 emissions to fall to 45% below 2010 levels by 2030 on the way to net-zero by 2050, with a 50% chance of meeting the 1.5C limit, with countries such as Canada's net-zero electricity needs in focus to get there.

The final pathway in this year’s outlook is a “delayed recovery scenario” (DRS), which shows what might happen if the coronavirus pandemic lingers and the global economy takes longer to recover, with knock-on reductions in the growth of GDP and energy demand.

New Mexico Energy Transition Act advances renewable energy, battery storage, energy efficiency, and demand response to boost grid reliability during climate change-fueled heatwaves, reducing emissions while supporting solar and wind deployment.

Key Points

A state policy phasing out power emissions, scaling renewables and storage, bolstering grid reliability in extreme heat.

✅ Replaces coal generation with solar plus battery storage

✅ Enhances grid reliability during climate-driven heatwaves

✅ Promotes energy efficiency and demand response programs

While temperatures hit record highs across much of the West in recent weeks and California was forced to curb electricity service amid heat-driven grid strain that week, the power stayed on in New Mexico thanks to proactive energy efficiency and conservation measures.

Public Service Company of New Mexico on Aug. 19 did ask customers to cut back on power use during the peak demand time until 9 p.m., to offset energy supply issues due to the record-breaking heatwave that was one of the most severe to hit the West since 2006. But the Albuquerque Journal's Aug. 28 editorial, "PRC should see the light with record heat and blackouts," confuses the problem with the solution. Record temperatures fueled by climate change – not renewable energy – were to blame for the power challenges last month. And thanks to the Energy Transition Act, New Mexico is reducing climate change-causing pollution and better positioned to prevent the worst impacts of global warming.

During those August days, more than 80 million U.S. residents were under excessive heat warnings. As the Journal's editorial pointed out, California experienced blackouts on Aug. 14 and 15 as wildfires swept across the state and temperatures rose. In fact, a recent report by the University of Chicago's Climate Impact Lab found the world has experienced record heat this summer due to climate change, and heat-related deaths will continue to rise in the future.

As the recent California energy incidents show, climate change is a threat to a reliable electricity system and our health as soaring temperatures and heatwaves strain our grid, as seen in Texas grid challenges this year as well. Demand for electricity rises as people depend more on energy-intensive air conditioning. High temperatures also can decrease transmission line efficiency and cause power plant operators to scale back or even temporarily stop electricity generation.

Lobbyists for the fossil fuel industry may claim that the service interruptions and the conservation requests in New Mexico demonstrate the need for keeping fossil-fueled power generation for electricity reliability, echoing policy blame narratives in California that fault climate policies. But fossil fuel combustion still is subject to the factors that cause blackouts – while also driving climate change and making resulting heatwaves more common. After an investigation, California's own energy agencies found no substance to the claim that renewable energy use was a factor in the situation there, and it's not to blame in New Mexico, either.

New Mexico's Energy Transition Act is a bold, necessary step to limit the damage caused by climate change in the future. It creates a reasonable, cost-saving path to eliminating greenhouse gas emissions associated with generating electricity.

The New Mexico Public Regulation Commission properly applied this law when it recently voted unanimously to replace PNM's coal-fired generation at San Juan Generating Station with carbon-free solar energy and battery storage located in the Four Corners communities, a prudent step given California's looming electricity shortage warnings across the West. The development will create jobs and provide resources for the local school district and help ensure a stronger economy and a healthier future for the region.

As we expand solar and wind energy here in New Mexico, we can help ensure reliable electricity service by building out greater battery storage for renewable energy resources. Expanding regional energy markets that can dispatch the lowest-cost energy from across the region to places where it is needed most would make renewable energy more available and reduce costs, despite concerns over policy exports raised by some observers.

Energy efficiency and demand response are important when we are facing extraordinary conditions, and proven strategies to improve electricity reliability show how demand-side tools complement the grid, so it is unfortunate that the Albuquerque Journal made the unsubstantiated claim that a stray cloud will put out the lights. It was hot, supplies were tight on the electric grid, and in those moments, we should conserve. We should not use those moments to turn our back on progress.

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.
