Carnegie Teams with Sumitomo for Grid-Scale Vanadium Flow Battery Storage

California Natural Gas Plant Rethink signals a shift toward clean energy, renewables, distributed solar, battery storage, and grid modernization as LADWP and regulators pause repowering plans amid an electricity oversupply and rising ratepayer costs.

Key Points

California pauses new gas plants to assess renewables, storage, and grid solutions for reliability.

✅ LADWP delays $2.2B gas repowers to study clean alternatives

✅ CEC weighs halting Oxnard plant amid grid oversupply

✅ Distributed solar, batteries, demand response boost reliability

California energy officials are, for the first time, rethinking plans to build expensive natural gas power plants in the face of an electricity glut and growing use of cleaner and cheaper energy alternatives.

The Los Angeles Department of Water and Power announced Tuesday that it has put a hold on a $2.2-billion plan to rebuild several old natural gas power plants while it studies clean energy alternatives to meet electricity demands. And the California Energy Commission may decide as early as Thursday to halt a natural gas project in Ventura County.

The scrutiny comes after an investigation found that the state is operating with an oversupply of electricity, driven largely by the construction of gas-fueled generating plants, leading to higher rates as regulators consider a rate overhaul to clean the grid. The state’s power plants are on track to be able to produce at least 21% more electricity than needed by 2020, according to the Times report.

Californians are footing a $40-billion annual bill while using less electricity, paying $6.8 billion more than they did in 2008 when power use in the state was at its all-time high. Electricity consumption has since fallen and remained largely flat.

Utilities in California have been on a years-long building binge, adding new natural gas plants even as the nation’s electricity system has undergone significant change, including consumer choice reforms that are reshaping the market.

Where utilities once delivered all electrical services from huge power plants along miles of transmission lines, the industry now must consider power delivered to the electric grid not only from its own sources, but also from solar systems and batteries at homes and businesses.

At the same time, utilities have been aggressively upgrading or rebuilding their aging natural gas plants — a move critics have said is unnecessary because consumers are using less power and clean energy technology is making those plants obsolete.

The DWP and energy commission moves involve as many as seven natural gas plant projects proposed for Southern California, despite warnings about a looming shortage if capacity is retired too fast, from Oxnard to Carlsbad, at a cost of more than $6 billion.

Reiko Kerr, the DWP’s senior assistant general manager of power systems, said given the changes in the energy world, the assessment is necessary to protect ratepayer dollars and the environment.

“The whole utility paradigm has shifted,” Kerr said in an interview. “We really are doing our ratepayers a disservice by not considering all viable options.

“We’re just looking at everything,” she said. “What can help us solve this reliability, renewable and greenhouse gas challenge that we all have?”

State and local governments have felt a heightened sense of urgency to deal with climate change after President Trump decided last week to withdraw the United States from the Paris climate accord.

California already has mandated that at least 50% of the state’s electricity come from clean energy sources by 2030. Senate leader Kevin de León (D-Los Angeles) wants to increase that to 100% by 2045.

Building or overhauling natural gas plants throughout Southern California, environmentalists argue, isn’t helping achieve those goals, even as some contend the state can't keep the lights on without gas during the transition.

The DWP’s move to delay plans for the fossil fuel plants, which seemed all but set to be built, came as a surprise to clean-energy advocates, who hailed the decision.

“This is a great first step toward smart energy investments that save customers money, ensure the lights stay on and protect our health and environment,” Graciela Geyer of the Sierra Club said.

The environmental group said that if the utility had moved ahead with the $2.2-billion investment in repowering natural gas plants, it “would have blown an irreparable hole in the city and the state’s hopes to achieve 100% generation” from clean energy sources.

Angela Johnson Meszaros, attorney at EarthJustice, said in a statement: "As our city struggles with the worst smog we’ve seen in years, we appreciate that LADWP is taking some much-needed time to reassess its plans to build fossil fuel power plants. We look forward to the day that LADWP announces that we are going to power our city with 100% clean energy.”

The gas-fired generating units slated for demolition and rebuilding are at the Scattergood, Haynes and Harbor electricity plants, which range from 34 to 67 years old.

As a group, the three plants have generated less than 20% of their combined capacity since 2001. The Harbor facility has operated on the low end at just 7%, while Haynes ran on the high end at 22%.

“The old model, the old legacy clunkers, won’t get us into the future we want,” DWP’s Kerr said.

DWP staff members told the utility’s’ commissioners Tuesday that their analysis of possible alternatives would be completed no later than early 2018.

Separately, the California Energy Commission this week is evaluating whether to halt a natural gas project in Ventura County after the state’s electric grid operator offered to conduct a study of clean energy alternatives to the roughly $250-million project on Mandalay Bay in Oxnard.

An energy commission committee has been deliberating since a hearing Monday during which Southern California Edison and the project’s developer, NRG Energy, argued that a study is simply a delay tactic that probably would kill a project needed to ensure reliable electric service and to avoid blackouts during peak demand.

The California Independent System Operator, which runs the state’s electric grid, told the energy commission that it would take three to four weeks to conduct its study on alternatives to the Oxnard natural gas project.

“Here we have an actual offer by the ISO to do such an analysis,” Ellison Folk, a lawyer representing the city of Oxnard, told the energy commission as she pushed for the study. “Its view that this is an analysis worth doing is something worth taking seriously.”

Energy commission members reviewing the study proposal are scheduled to meet again Thursday to consider the offer.

The board of governors for the California Independent System Operator made the unusual offer at its May 1 meeting to conduct a eleventh-hour study of clean-energy alternatives to building a new natural gas plant.

“If we’re going to be moving forward with a gas plant at this time, in this juncture, in the context of everything that’s going on, not evaluating other alternatives that are viable, noncombustion alternatives, is a missed opportunity,” Angelina Galetiva. a commission board member, said during the May 1 meeting.

Ilorin Electricity Theft Device delivers remote monitoring and IoT-based detection for smart meters, identifying bypassed prepaid meters, triggering disconnects, and alerting the utility control room to curb distribution losses and energy theft.

Key Points

A prototype IoT system that detects electricity theft, enables remote disconnection, and alerts utility control rooms.

✅ Remote monitoring flags bypassed prepaid meters.

✅ Sends alerts to utility control room with customer details.

✅ Enables safe remote cut-off to reduce distribution losses.

The Department of Electrical and Electronics Engineering, University of Ilorin, has unveiled a prototype anti-theft device capable of remotely monitoring and detecting customers stealing electricity.

The Acting Head of the Department, Dr Mudathir Akorede told newsmen on Tuesday in Ilorin that the device could also cut off electricity supply to the premises of customers stealing electricity.

”This will simultaneously send a message to the utility control room, and in light of rising ransomware attacks targeting power systems, to alert the system operator with such customer’s details displayed on the control panel,” he said.

Akorede said that processes of filing application for patenting the invention, in line with emerging IoT security standards for the electricity sector, had commenced through the university’s Laboratory to Product Centre.

The don explained that the device was developed by himself and some students of the Department, reflecting how university teams contribute to innovations like generating electricity from falling snow in the field.

Akorede said, “I gave the project to my undergraduate students; they carried out the project to a level and I took it over and brought it to a level that was up to standard.”

The Don further said,”The invention is now up to the standard that it can be patented.

“I have brought this to the attention of the Ibadan Electricity Distribution Company, although not officially, but if adopted, and as utilities pursue digitizing the grid strategies, the device would enable distribution companies to cut their commercial losses substantially.”

He said that the idea followed the discovery that most people use electricity without paying for it.

”A lot of people that have been able to get the prepaid meter, even though they can afford to pay their bills, still want to bypass this thing to steal electricity and this is not helping the companies.

“It is not helping all of us as a whole. If the industry should collapse, with emerging cyber weapons that can disrupt power grids underscoring systemic risks, everybody would bear the brunt of that problem and that is why the consumers too have to share out of the problem

“But this is not to say that distribution companies also do not have their share of the blame by not wanting to take on responsibilities such as faulty transformers.”

Israel Coal Reduction accelerates the energy transition, cutting coal use in electricity production by 30% as IEC shifts to natural gas, retires Hadera units, and targets a 2030 phase-out to lower emissions.

Key Points

Plan to cut coal power by 30%, retire IEC units, and end coal by 2030, shifting electricity generation to natural gas.

✅ 30% immediate cut in coal use for electricity by IEC

✅ Hadera units scheduled for retirement and gas replacement by 2022

✅ Complete phase-out of coal and gasoil in power by 2030

Israel's Energy and Water and Environmental Protection Ministers have ordered an immediate 30% reduction in coal use for electricity production by state utility Israel Electric Corporation as the country increases its dependence on domestic natural gas.

IEC, which operates four coal power plants with a total capacity of 4,850 MW and imports thermal coal from Australia, Colombia, Russia and South Africa, has been planning, as part of the decision to reduce coal use, to shut one of its coal plants during autumn 2018, when demand is lowest.

Israel has already decided to shut the four units of the oldest coal power plant at Hadera by 2022, echoing Britain's coal-free week milestones, and replace the capacity with gas plants.

"By 2030 Israel will completely stop the use of coal and gasoil in electricity production," minister Yuval Steinmetz said.

Coal consumption peaked in 2012 at 14 million mt and has declined steadily, aligning with global trends where renewables poised to eclipse coal in power generation, with the coming on line of Israel's huge Tamar offshore gas field in 2013.

In 2015 coal accounted for more than 50% of electricity production, even as German renewables outpaced coal in generation across that market. Coal's share would decline to less than 30% under the latest decision.

Israel's coal consumption in 2016 totaled 8.7 million mt, as India rationed coal supplies amid surging demand, and was due to decline to 8 million mt last year.

Three years ago, the ministers ordered a 15% reduction in coal use, while Germany's coal generation share remained significant, and the following year a further 5% cut was added.

Vehicle-to-Grid (V2G) enables bidirectional charging, letting EV batteries supply smart grid services to large buildings, support renewable energy integration, reduce battery degradation, and optimize demand response for efficient, resilient power management.

Key Points

Vehicle-to-Grid (V2G) is bidirectional EV charging that feeds the grid and buildings while protecting battery health.

✅ Uses idle EVs to power buildings and support renewables

✅ Smart algorithms minimize lithium-ion battery degradation

✅ Provides grid services, demand response, and peak shaving

Stored energy from electric vehicles (EVs) can be used to power large buildings -- creating new possibilities for the future of smart, renewable energy -- thanks to ground-breaking battery research from WMG at the University of Warwick.

Dr Kotub Uddin, with colleagues from WMG's Energy and Electrical Systems group and Jaguar Land Rover, has demonstrated that vehicle-to-grid (V2G) technology can be intelligently utilised to take enough energy from idle EV batteries to be pumped into the grid and power buildings -- without damaging the batteries.

This new research into the potentials of V2G shows that it could actually improve vehicle battery life by around ten percent over a year.

For two years, Dr Uddin's team analysed some of the world's most advanced lithium ion batteries used in commercially available EVs -- and created one of the most accurate battery degradation models existing in the public domain -- to predict battery capacity and power fade over time, under various ageing acceleration factors -- including temperature, state of charge, current and depth of discharge.

Using this validated degradation model, Dr Uddin developed a 'smart grid' algorithm, which supports grid coordination and intelligently calculates how much energy a vehicle requires to carry out daily journeys, and -- crucially -- how much energy can be taken from its battery without negatively affecting it, or even improving its longevity.

The researchers used their 'smart grid' algorithm to see if they could power WMG's International Digital Laboratory -- a large, busy building which contains a 100-seater auditorium, two electrical laboratories, teaching laboratories, meeting rooms, and houses approximately 360 staff -- with vehicle-to-building charging from EVs parked on the University of Warwick campus.

They worked out that the number of EVs parked on the campus (around 2.1% of cars, in line with the UK market share of EVs) could spare the energy to power this building, acting as capacity on wheels for electricity networks -- and that in doing so, capacity fade in participant EV batteries would be reduced by up to 9.1%, and power fade by up to 12.1% over a year.

It has previously been thought that extracting energy from EVs with V2G technology causes their lithium ion batteries to degrade more rapidly.

Dr Uddin's group (along with collaborators from Jaguar Land Rover) have proved, however, that battery degradation is more complex -- and this complexity, in operation, can be exploited to improve a battery's lifetime.

Given that battery degradation is dependent on calendar age, capacity throughput, temperature, state of charge, current and depth of discharge, V2G is an effective tool that can be used to optimise a battery's conditions such that degradation is minimised. Hence, taking excess energy from an idle EV to power the grid actually keeps the battery healthier for longer.

Dr Uddin commented on the research:

"These findings reinforce the attractiveness of vehicle-to-grid technologies to automotive Original Equipment Manufacturers: not only is vehicle-to-grid an effective solution for grid support -- and subsequently a tidy revenue stream -- but we have shown that there is a real possibility of extending the lifetime of traction batteries in tandem.

"The results are also appealing to policy makers interested in grid decarbonisation and addressing grid challenges from rising EVs across power systems."

The research, 'On the possibility of extending the lifetime of lithium-ion batteries through optimal V2G facilitated by an integrated vehicle and smart-grid system' is published in Energy.

It was funded by the Engineering and Physical Sciences Research Council and the WMG centre High Value Manufacturing Catapult, in partnership with Jaguar Land Rover.

Ontario Hydro Rate Cuts address soaring electricity prices, lowering hydro bills via refinancing, FAO-reviewed costs, and long-term infrastructure investment, balancing ratepayer relief with a projected $21 billion net expense over 30 years.

Key Points

Ontario electricity bill relief spreading infrastructure and green energy costs over 30 years via refinancing.

✅ 25% average bill cut; $156 to $123 per month

✅ FAO projects $21B net cost over 30 years

✅ Costs shifted to long-term debt, infrastructure, green energy

Premier Kathleen Wynne is making no apologies for the Liberals’ 25 per cent hydro rate cuts, legislation to lower electricity rates that a legislative watchdog warns will cost at least $21 billion over three decades.

In the wake of Financial Accountability Officer Stephen LeClair’s report on the “Fair Hydro Plan,” Wynne emphasized that Ontario electricity consumers demanded and deserved relief.

“You all read the newspaper, you listen to the radio and you watch television — you know the problems that families are having around the province paying for their electricity costs,” the premier told reporters Thursday in Timmins.

That’s why the government moved forward with a rate cut, with recent Hydro One reconnections underscoring the stakes, that will see the average household’s monthly hydro bill drop from $156 to $123 once it fully takes effect next month.

In a 15-page report released Wednesday, the financial accountability officer estimated the initiative would cost the province $45 billion over the next 29 years amid a cabinet warning on prices that electricity costs could soar, while saving ratepayers $24 billion for a next expense of $21 billion.

Both the Progressive Conservatives and the New Democrats oppose the Liberal rate cut, arguing that a deal with Quebec would not lower hydro bills.

But Wynne said the government has in effect renegotiated a mortgage so it will bankroll hydro infrastructure improvements over a longer time period, though some have urged the next government to scrap the Fair Hydro Plan and review options, in order to give customers a break now.

“We’re talking about a 30-year window here. It took at least 30 years, probably 40 years, to let the electricity system degrade to the stage that it had in 2003,” she said, noting “we were having blackouts and brownouts around the province” before her party took office that year.

“There were thousands of kilometres of line that needed to be rebuilt . . . that work hadn’t been done over those generations, so electricity costs were low over that period of time but the work wasn’t being done.”

When her predecessor Dalton McGuinty came to power in 2003, Wynne said Queen’s Park began spending billions on infrastructure improvements, including expensive subsidies for green energy, such as wind turbines and solar panels.

“There’s a lot of work that has been done since then. Literally thousands of kilometres of line have been rebuilt. The coal-fired plants have been shut down. The air is cleaner. There’s less pollution in the air. The system is reliable and renewable,” she said.

“So there’s a cost associated with that and what was happening was that was work that had to be done — and all of those costs were on the shoulders of people today.”

Wynne noted “this electricity grid is an asset that is going to be used for generations to come.”

“My grandchildren are going to benefit from this asset, so I think it’s fair that we spread the cost of that over that 30-year period,” she said.

“That’s how we made this decision.”

US Shift From Coal to Renewables accelerates as natural gas, solar, and wind power gain market share, driven by the Paris climate agreement, clean energy mandates, smart grid upgrades, and energy efficiency.

Key Points

An industry trend where power producers replace coal with natural gas, solar, and wind to meet clean energy goals.

✅ Shareholders and customers demand cleaner power portfolios

✅ Natural gas, solar, and wind outcompete coal on cost and risk

✅ Smart grid and efficiency investments reduce emissions further

President Trump once again promised to revive the U.S. coal industry when he announced his intention to withdraw the U.S. from the Paris climate agreement.

But that reversal seems as unlikely as ever as electric power producers, the biggest consumers of coal in the U.S., continue to shift to natural gas and renewable energy sources like solar and wind power. In 2016, natural gas became the leading fuel for U.S. electricity generation for the first time, responsible for 33.8% of the output, compared with 30.4% for coal, according to the U.S. Energy Information Administration, even as coal-fired generation was projected to rise in 2021 in the short term.

Nick Akins, the CEO of American Electric Power, one of the largest utilities in the U.S., says the preference for gas, renewables and energy efficiency, will only grow in response to increasing demands from shareholders and customers for cleaner energy, regardless of changes in national energy policy.

With 5.4 million customers in 11 states, AEP plans to spend $1.5 billion on renewable energy from 2017 through 2019, and $13 billion on transmission and distribution improvements, including new “smart” technologies that will make the grid more resilient and efficient, AEP says.

We spoke with Akins on Thursday, just after Trump’s announcement. The transcript is edited for length and clarity.

What do you think of Trump’s decision to pull the U.S. from the climate agreement?

I don’t think it’s unexpected. He obviously made the point that he’s willing to renegotiate or have further dialogue about it. That’s a good sign. From our perspective, we’re going to continue along the path we’re already on toward a cleaner energy economy.

AEP and the U.S. electric power industry in general have been moving away from coal in favor of natural gas and renewable energy. Will this decision by the Trump administration have any impact on that trend?

If you look at our resource plans in all of the states we serve, they are focused on renewables, natural gas and transmission, as declining returns from coal generation pressure investment choices across the industry. And big-data analytics improves the efficiency of the grid, so energy efficiency is obviously a key component, as Americans use less electricity overall.

Our carbon dioxide emissions in 2016 were 44% below 2000 levels, and that progress will continue with the additions of more renewables, energy efficiency and natural gas.

So, you don’t see coal making a comeback at AEP or other utilities?

No, I don’t think so. … You wouldn’t make a decision (to build a coal power plant) at this point because it’s heavily capital-intensive, and involves a longer-term process and risk to build. And, of course, you can add renewables that are very efficient and natural gas that’s efficient and much less expensive and risky, in terms of construction and operation.

Do you plan to close any more coal-powered plants soon? 

I suspect we’ll see some more retirements in the future, with coal and nuclear closures test just transition in many communities, and as we progress towards that cleaner energy economy, and consider the expectations of our customers and shareholders for us to mitigate risk, you’ll continue to see that happen.

But on the other hand, I want to make sure there’s an understanding that coal will remain a part of the portfolio, even though in rare cases new coal plants are still being built where options are limited, but it will be of a lesser degree because of these other resources that are available to us now that weren’t available to us just a few years ago.

Do you find yourself under more or less pressure from customers and shareholders to move to cleaner forms of energy?

I think there’s more pressure. Investors are looking for the sustainability of the company going forward and mitigation of risks … From a customer standpoint, we have some large customers interested in moving into our service territory who are looking for cleaner energy, and want to know if we’re focused on that. Some of them want to be supplied entirely by those clean sources. So, we’re clearly responding to our customers’ and our shareholders’ expectations.

What’s the solution for workers at coal mines and coal power plants who have lost their jobs?

Certainly, the skill sets of employees in mining and around machinery are transferable to other areas of manufacturing, like aerospace and defense. So, we’re really focusing on economic-development efforts in our service territories … particularly in the coal states … to bring coal miners back to work, not necessarily in coal mines but certainly (in manufacturing).
