Centrica acquires battery storage project that could "unlock North Sea wind energy potential"

UK Home Solar Panel Installation drives self-consumption as PV panels, hybrid inverters, and smart meters cut grid demand, enable EV charging, and prepare battery storage, even in cloudy winters, with app-based monitoring and MCS-certified installers.

Key Points

A residential PV setup reducing grid reliance via panels, hybrid inverters, smart meters, and battery-ready design.

✅ Cuts grid use; boosts self-consumption with PV generation

✅ Hybrid inverters enable future battery storage integration

✅ Smart meter and app monitor output, EV charging patterns

In a town north of London, the weather's been cloudy over the winter months. But it didn't stop this homeowner from installing solar panels in December.

On his smart metre, Kumi Thiruchelvam looks satisfied at the "0 watts" showing up under electricity. It's about 10 am, and he's not using any electricity from the grid.

Cost of installation? Between £12,000 and £13,000 (€13,500-€14,500), a fair chunk of savings, even for Thiruchelvam, who lives on a private avenue in Luton.

The investment was common sense for him following the surge in energy prices caused by the Russian invasion of Ukraine.

According to the Office of National Statistics, electricity prices in the UK had increased by 67 per cent in January 2023 compared to January 2022, while pilots show parked EVs can earn from grids in Europe, offering some relief.

Solar power installations doubled in 2022 compared to 2021, according to MCS, the standards organisation in charge of solar installations, a shift aligned with the UK grid's net-zero transition underway today.

"We've had a combination of soaring energy prices around the world, and then also we've increased our electricity consumption in the home through a number of reasons, including electric vehicles and emerging EV-solar integration trends," says Thiruchelvam.

His family owns a big house and no less than three electric vehicles, some of which can now power a home for days during outages, so their electricity consumption is higher than the normal household, about 12,000 kWh per year.

Around two-thirds should now be provided by solar panels, and EV owners can sell electricity back to the grid in some schemes as well, diversifying benefits.

"We originally sought the configuration to be rear, which is where the sun comes up, but we went for the front because it spends more time in the front throughout most of the year than in the rear. Also, there's more shade in the rear with trees," he says.

To get a quote for the installation, Thiruchelvam used Otovo, a Norwegian company which recently launched in the UK.

Using their app, he can monitor the electricity generated by his photovoltaic (PV) installation from his phone. The data comes from the inverters installed in the attic.

Their role is to change the direct current generated by the solar panels into alternating current to power appliances in the house safely.

They also communicate with the grid and monitor the electricity generated, supporting emerging vehicle-to-building charging strategies for demand management.

"We went for two hybrid inverters, allowing me to use a battery in the future or tap stored EV energy for buildings if needed," says Thiruchelvam.

"But because battery technology is still evolving, I chose not to. And also I viewed at that time that we would be consuming everything we'd be generating. So we didn't. But most likely I will upgrade the system as we approach summer with batteries."

DOE Battery Workforce Strategy advances lithium battery manufacturing with DOE, DOL, and AFL-CIO partnerships, pilot training programs, EV supply chain skills, and industry-labor credentials to strengthen clean energy jobs and domestic competitiveness.

Key Points

An initiative to fund pilot training and labor-industry partnerships to scale domestic lithium battery manufacturing.

✅ $5M for up to five pilot training programs.

✅ Builds industry-labor credentials across the battery supply chain.

✅ Targets EV manufacturing, recycling, and materials refining.

The U.S. Department of Energy (DOE), in coordination with the U.S. Department of Labor and the AFL-CIO, today announced the launch of a national workforce development strategy for lithium-battery manufacturing. As part of a $5 million investment, DOE will support up to five pilot training programs in energy and automotive communities and advance workforce partnerships between industry and labor for the domestic lithium battery supply chain. Lithium batteries power everything from electric vehicles, where U.S. automakers' battery strategies are rapidly evolving, to consumer electronics and are a critical component of President Biden’s whole-of-government decarbonization strategy. This workforce initiative will support the nation’s global competitiveness within battery manufacturing while strengthening the domestic economy and clean energy supply chains. 

“American leadership in the global battery supply chain, as the U.S. works with allies on EV metals to strengthen access, will be based not only on our innovative edge, but also on our skilled workforce of engineers, designers, scientists, and production workers,” said U.S. Secretary of Energy Jennifer M. Granholm, “President Biden has a vision for achieving net zero emissions while creating millions of good paying, union jobs — and DOE’s battery partnerships with labor and industry are key to making that vision a reality.” 

“President Biden has made the creation of good union jobs a cornerstone of his climate strategy,” said AFL-CIO President Liz Shuler. “We applaud DOE for being proactive in pulling labor and management together as the domestic battery industry is being established, and as Canada accelerates EV assembly nearby, we look forward to working with DOE and DOL to develop high-road training standards for the entire battery supply chain.” 

“I am glad to see the Department of Energy collaborating with our industry partners to invest in the next generation of our clean energy workforce,” said U.S. Senator Joe Manchin (D-WV), Chairman of the Senate Energy and Natural Resources Committee. “While I remain concerned about our dependence on China and other foreign countries for key parts of the lithium-ion battery supply chain, and recent lithium supply risks highlight the urgency, engaging our strong and capable workforce to manufacture batteries domestically is a critical step toward reducing our reliance on other countries and ensuring we are able to maintain our energy security. I look forward to seeing this initiative grow, and we will continue to work closely together to ensure we can onshore the rest of the battery supply chain.” 

The pilot training programs will bring together manufacturing companies, organized labor, and training providers to lay the foundation for the development of a broad national workforce strategy. The pilots will support industry-labor cooperation, as major North American projects like the B.C. battery plant advance, and will provide sites for job task analyses and documenting worker competencies. Insights gained will support the development of national industry-recognized credentials and inform the development of broader training programs to support the overall battery supply chain. 

This initiative comes as part of suite of announcements from President Biden’s Interagency Working Group (IWG) on Coal and Power Plant Communities and Economic Revitalization—a partnership among the White House and nearly a dozen federal agencies committed to pursuing near- and long-term actions to support coal, oil and gas, and power plant communities as the nation transitions to a clean energy economy. 

This announcement follows DOE’s recent release of two Notices of Intent authorized by the Bipartisan Infrastructure Law to provide $3 billion to support projects that bolster domestic battery manufacturing and battery recycling for a circular economy efforts nationwide. The funding, which will be made available in the coming months, will support battery-materials refining, which will bolster domestic refining capacity of minerals such as lithium, as well as production plants, battery cell and pack manufacturing facilities, and recycling facilities. 

It also builds on progress the Biden-Harris Administration and DOE have driven to secure a sustainable, reliable domestic supply of critical minerals and materials necessary for clean energy supply chains, including lithium, with emerging sources like Alberta's lithium-rich oil fields underscoring regional potential. This includes $44 million in funding through the DOE Mining Innovations for Negative Emissions Resource Recovery (MINER) program to fund the technology research that increases the mineral yield while decreasing the required energy, and subsequent emissions, to mine and extract critical minerals such as lithium, copper, nickel, and cobalt.

US Solar Electricity Generation 2022 rose to a 4.7% share, with 202,256 GWh, per EIA Electric Power Monthly; driven by PV capacity additions despite import constraints, alongside renewables trends in wind, nuclear, and hydroelectric output.

Key Points

The share and output of US solar PV in 2022: 4.7% of electricity and 202,256 GWh, as reported by the EIA.

✅ Solar PV reached 4.7% of US power; 202,256 GWh generated in 2022.

✅ Monthly share varied from about 3% in Jan to just over 6% in Apr.

✅ Wind was 10.1%; wind+solar hit slightly over 20% in April.

In 2022, solar photovoltaics made up 4.7% of U.S. electricity generation, an increase of almost 21% over the 2021 total when solar produced 3.9% of US electricity and about 3% in 2020 according to long-term outlooks. Total solar generation was up 25%, breaking through 200,000 GWh for the year.

The record deployment volumes of 2020 when renewables became the second-most U.S. electricity source and 2021 are the main factors behind this increase. If it were not for ongoing solar panel import difficulties and general inflation, solar’s contribution to electricity generation might have reached 5% in 2022. The data was released by the Department of Energy’s Energy Information Administration (EIA) in their Electric Power Monthly. This release includes data from December 2022, as well as the rest of the data from 2022.

Solar as a percentage of monthly electricity generation ranged from a low of almost 3% in January, to just over 6% in April. April’s production marked a new monthly record for solar generation in the US and coincided with a renewables share record that month.

Total generation of solar electricity peaked in July, at 21,708 GWh. Over the course of the year, solar production reached  202,256 GWh, and total U.S. electricity generation reached 4,303,980 GWh, a year in which renewables surpassed coal in the power mix overall. Total US electricity generation increased by 3.5% over the 4,157,467 GWh produced in 2021.

In 2022, wind energy contributed 10.1% of the total electricity generated in the United States. Wind and solar together produced 14.8% of U.S. electricity in 2022, growing from the 13% recorded in 2021. In April, when solar power peaked at just over 6%, wind and solar power together reached a peak of slightly over 20%, as a wind-and-solar milestone versus nuclear was noted that month, a new monthly record for the two energy sources.

In total, emissions free energy sources such as wind, solar photovoltaic and thermal, nuclear, hydroelectric, and geothermal, accounted for 37.9% of the total electricity generated in the U.S., while renewables provided about 25.5% share of the mix during the year. This value is barely higher than 2020’s 37.7% – but represents a return to growth after 2021 saw a decrease in emission free electricity to 37%.

Nuclear power was the most significant contributor to emission free electricity, making up a bit more than 45% of the total emissions free electricity. Wind energy ranked second at 26%, followed by hydroelectricity at 15%, and solar photovoltaic at 12%, confirming solar as the #3 renewable in the U.S. mix.

Emissions free electricity is a different summation than the EIA’s ‘Renewable Energy’ category. The Renewable Energy category also includes:

• Wood and Wood-Derived Fuels
• Landfill Gas
• Biogenic Municipal Solid Waste
• Other Waste Biomass

Nuclear produced 17.9% of the total U.S. electricity, a value that has generally stayed flat over the years. However, since nuclear facilities are being retired faster than new facilities are coming online, nuclear production has fallen in the past two years. After multiple long delays, we will probably see reactor three of the Vogtle nuclear facility come online in 2023. Reactor four is officially scheduled to come online later this year.

Hydroelectric production also declined in 2022, due to drought conditions in the southwestern United States. With rain and snow storms in California and the southwest, hydroelectricity generation may rebound in 2023.

Utility-Controlled EV Charging shapes who builds charging stations as utilities, regulators, and private networks compete over infrastructure, grid upgrades, and pricing, impacting ratepayers, competition, and EV adoption across states seeking cleaner transport.

Key Points

Utility-controlled EV charging is utilities building charging networks affecting rates, competition and grid costs.

✅ Regulated investment may raise rates before broader savings.

✅ Private firms warn monopolies stifle competition and innovation.

✅ Regulators balance access, equity, and grid upgrade needs.

Electric vehicles are widely seen as the automobile industry’s future, but a battle is unfolding in states across America over who should control the charging stations that could gradually replace fuel pumps.

From Exelon Corp. to Southern California Edison, utilities have sought regulatory approval to invest millions of dollars in upgrading their infrastructure as state power grids adapt to increased charging demand, and, in some cases, to own and operate chargers.

The proposals are sparking concerns from consumer advocates about higher electric rates and oil companies about subsidizing rivals. They are also drawing opposition from startups that say the successors to gas stations should be open to private-sector competition, not controlled by monopoly utilities.

That debate is playing out in regulatory commissions throughout the U.S. as states and utilities promote wider adoption of electric vehicles. At stake are charging infrastructure investments expected to total more than $13 billion over the next five years, as an American EV boom accelerates, according to energy consulting firm Wood Mackenzie. That would cover roughly 3.2 million charging outlets.

Calvin Butler Jr., who leads Exelon’s utilities business, said many states have grown more open to the idea of utilities becoming bigger players in charging as electric vehicles have struggled to take off in the U.S., where they make up only around 2% of new car sales.

“When the utilities are engaged, there’s quicker adoption because the infrastructure is there,” he said.

Major auto makers including General Motors Co. and Ford Motor Co. are accelerating production of electric vehicles, and models like Tesla’s Model 3 are shaping utility planning, and a number of states have set ambitious EV goals—most recently California, which aims to ban the sale of new gasoline-powered cars by 2035. But a patchy charging-station network remains a huge impediment to mass EV adoption.

Democratic presidential candidate Joe Biden has called for building more than 500,000 new public charging outlets in a decade as part of his plan to combat climate change, amid Biden’s push to electrify the transportation sector. But exactly how that would happen is unclear. The U.S. currently has fewer than 100,000 public outlets, according to the Energy Department. President Trump, who has weakened federal tailpipe emissions targets, hasn’t put forward an electric-vehicle charging plan, though he backed a 2019 transportation bill that would have provided $1 billion in grants to build alternative fueling infrastructure, including for electric vehicles.

Charging access currently varies widely by state, as does utility involvement, with many utilities bullish course on EV charging to support growth, which can range from providing rebates on home chargers to preparing sites for public charging—and even owning and operating the equipment needed to juice up electric vehicles.

As of September, regulators in 24 states had signed off on roughly $2.6 billion of utility investment in transportation electrification, according to Atlas Public Policy, a Washington, D.C., policy firm. More than half of that spending was authorized in California, where electric vehicle adoption is highest.

Nearly a decade ago, California blocked utilities from owning most charging equipment, citing concerns about potentially stifling competition. But the nation’s most populous state reversed course in 2014, seeking to spur electrification.

Regulators across the country have since been wrestling with similar questions, generating a patchwork of rules.

Maryland regulators signed off last year on a pilot program allowing subsidiaries of Exelon and FirstEnergy Corp. to own and operate public charging stations on government property, provided that the drivers who use them cover at least some of the costs.

Months later, the District of Columbia rejected an Exelon subsidiary’s request to own public chargers, saying independent charging companies had it covered.

Some charging firms argue utilities shouldn’t be given monopolies on car charging, though they might need to play a role in connecting rural customers and building stations where they would otherwise be uneconomical.

“Maybe the utility should be the supplier of last resort,” said Cathy Zoi, chief executive of charging network EVgo Services LLC, which operates more than 800 charging stations in 34 states.

Utility charging investments generally are expected to raise customers’ electricity bills, at least initially. California recently approved the largest charging program by a single utility to date: a $436 million initiative by Southern California Edison, an arm of Edison International, as the state also explores grid stability opportunities from EVs. The company said it expects the program to increase the average residential customer’s bill by around 50 cents a month.

But utilities and other advocates of electrification point to studies indicating greater EV adoption could help reduce electricity rates over time, by giving utilities more revenue to help cover system upgrades.

Proponents of having utilities build charging networks also argue that they have the scale to do so more quickly, which would lead to faster EV adoption and environmental improvements such as lower greenhouse gas emissions and cleaner air. While the investments most directly help EV owners, “they accrue immediate benefits for everyone,” said Jill Anderson, a Southern California Edison senior vice president.

Some consumer advocates are wary of approving extensive utility investment in charging, citing the cost to ratepayers.

“It’s like, ‘Pay me now, and maybe someday your rates will be less,’” said Stefanie Brand, who advocates on behalf of ratepayers for the state of New Jersey, where regulators have yet to sign off on any utility proposals to invest in electric vehicle charging. “I don’t think it makes sense to build it hoping that they will come.”

Groups representing oil-and-gas companies, which stand to lose market share as people embrace electric vehicles, also have criticized utility charging proposals.

“These utilities should not be able to use their monopoly power to use all of their customers’ resources to build investments that definitely won’t benefit everybody, and may or may not be economical at this point,” said Derrick Morgan, who leads federal and regulatory affairs at the American Fuel & Petrochemical Manufacturers, a trade organization.

Utility executives said their companies have long been used to further government policy objectives deemed to be in the public interest, drawing on lessons from 2021 to guide next steps, such as improving energy efficiency.

“This isn’t just about letting market forces work,” said Mike Calviou, senior vice president for strategy and regulation at National Grid PLC’s U.S. division.

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.

Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

UK Wind Power Leadership in 2020 highlights record renewable energy growth, G20-leading wind share, rapid coal phase-out, and rising solar integration, advancing decarbonization targets under the Paris Agreement and momentum ahead of COP26.

Key Points

The UK led the G20 in wind power share in 2020, displacing coal, expanding solar, and cutting power-sector emissions.

✅ G20-leading wind share; second for combined wind and solar

✅ Fastest coal decline among G20 from 2015 to 2020

✅ Emissions risk rising as post-pandemic demand returns

Nearly a quarter of the UK’s electricity came from wind turbines in 2020 – making the country the leader among the G20 for share of power sourced from the renewable energy, a new analysis finds.

The UK also moved away from coal power at a faster rate than any other G20 country from 2015 to 2020, according to the results.

And it ranked second in the G20, behind Germany, for the proportion of electricity sourced from both wind and solar in 2020, after first surpassing coal in 2016.

“It’s crazy how much wind power has grown in the UK and how much it has offset coal, and how it’s starting to eat at gas,” Dave Jones, Ember’s global lead analyst, told The Independent.

But it is important to bear in mind that “we’re only doing a great job by the standards of the rest of the world”, he added, noting that low-carbon generation stalled in 2019 in the UK.

Ember’s Global Electricity Review notes that the world’s power sector emissions were two per cent higher in 2020 than in 2015 – the year that countries agreed to slash their greenhouse gas pollution as part of the Paris Agreement.

Power generated from coal fell by a record amount from 2019 to 2020, the analysis finds. However, this decline was greatly facilitated by lockdowns introduced to stop the spread of Covid-19, as global electricity demand was temporarily stifled before rebounding, the analysts say.

Coal is the most polluting of the fossil fuels. The UK government hopes to convince all countries to stop building new coal-fired power stations at Cop26, a climate conference that is to be held in Glasgow later this year.

UN chief Antonio Guterres has also called for all countries to end their “deadly addiction to coal”.

At a summit held earlier this month, he described ending the use of coal in electricity generation as the “single most important step” to meeting the Paris Agreement’s goal of limiting global warming to well below 2C above pre-industrial levels by 2100.

“There is definitely a concern that, in the pandemic year of 2020, coal hasn’t fallen as fast as it needed to,” said Mr Jones, even as the UK set coal-free power records recently.

“There is concern that, once electricity demand returns, we won’t be seeing that decline in coal anymore.”
