Before buying a wind turbine, a homeowner should learn how much electricity he uses (utility companies can provide a usage history), and assess local wind speeds.

For most states, wind speed information can be found at www.eere.energy.gov/windandhydro/windpoweringamerica/wind_maps.asp.

The maps donÂ’t account for variations due to altitude, tree lines and ground-level brush. While itÂ’s possible to measure a propertyÂ’s winds more precisely with an anemometer, most wind-turbine dealers donÂ’t require that level of precision to recommend a turbine size.

At awea.org/smallwind, the American Wind Energy Association has guides to selecting and installing turbines, and lists of manufacturers and state incentives. The New York State Energy Research and Development Authority lists rebate amounts and eligible wind installers at www.powernaturally.org. Information for New Jersey residents is available at njcleanenergy.com.

West Coast consumers won't benefit if Trump privatizes the electrical grid

BPA Privatization would sell the Bonneville Power Administration's transmission lines, raising FERC-regulated grid rates for ratepayers, impacting hydropower and the California-Oregon Intertie under the Trump 2018 budget proposal in the Pacific Northwest region.

 

Key Points

Selling Bonneville's transmission grid to private owners, raising rates and returns, shifting costs to ratepayers.

✅ Trump 2018 budget targets BPA transmission assets for sale.

✅ Higher capital costs, taxes, and profit would raise transmission rates.

✅ California-Oregon Intertie and hydropower flows face price impacts.

 

President Trump's 2018 budget proposal is so chock-full of noxious elements — replacing food stamps with "food boxes," drastically cutting Medicaid and Medicare, for a start — that it's unsurprising that one of its most misguided pieces has slipped under the radar.

That's the proposal to privatize the government-owned Bonneville Power Administration, which owns about three-quarters of the high-voltage electric transmission lines in a region that includes California, Washington state and Oregon, serving more than 13.5 million customers. By one authoritative estimate, any such sale would drive up the cost of transmission by 26%-44%.

The $5.2-billon price cited by the Trump administration, moreover, is nearly 20% below the actual value of the Bonneville grid — meaning that a private buyer would pocket an immediate windfall of $1.2 billion, at the expense of federal taxpayers and Bonneville customers.

Trump's plan for Portland, Ore.-based Bonneville is part of a larger proposal to sell off other government-owned electricity bodies, including the Colorado-based Western Area Power Administration and the Oklahoma-based Southwestern Power Administration. But Bonneville is by far the largest of the three, accounting for nearly 90% of the total $5.8 billion the budget anticipates collecting from the sales. The proposal is also part of the administration's

Both plans are said to be politically dead-on-arrival in Washington. But they offer a window into the thinking in the Trump White House.

"The word 'muddle' comes to mind," says Robert McCullough, a respected Portland energy consultant, referring to the justification for the privatization sale included in the Trump budget.

The White House suggests that selling the Bonneville grid would result in lower costs. But that narrative, McCullough wrote in a blistering assessment of the proposal, "displays a severe lack of understanding about the process of setting transmission rates."

McCullough's assessment is an update of a similar analysis he performed when the privatization scheme was first raised by the Trump administration last year. In that analysis issued in June, McCullough said the proposal "raises the question of why these valuable assets would be sold at a discount — and who would get the benefit of the discounted price."

The implications of a sale could be dire for Californians. Bonneville is the majority owner of the California-Oregon Intertie, an electrical transmission system that carries power, including Columbia River-generated hydropower and other clean-energy generation in British Columbia that supports the regional exchange, south to California in the summer and excess California generation to the Pacific Northwest in the winter.

But the idea has drawn fire throughout the region. When it was first broached last year, the Public Power Council, an association of utilities in the Northwest, assailed it as an apparent "transfer of value from the people of the Northwest to the U.S. Treasury," drawing parallels to Manitoba Hydro governance issues elsewhere.

The region's political leaders had especially harsh words for the idea this time around. "Oregonians raised hell last year when Trump tried to raise power bills for Pacific Northwesterners by selling off Bonneville Power, and yet his administration is back at it again," Sen. Ron Wyden (D-Ore.) said after the idea reappeared. "Our investment shouldn't be put up for sale to free up money for runaway military spending or tax cuts for billionaires." Sen. Maria Cantwell (D-Wash.) promised in a statement to work to "stop this bad idea in its tracks."

The notion of privatizing Bonneville predates the Trump administration; it was raised by Bill Clinton and again by George W. Bush, who thought the public would gain if the administration could sell its power at market rates. Both initiatives failed.

The same free-enterprise ideology underlies the Trump proposal. Privatizing the transmission lines "encourages a more efficient allocation of economic resources and mitigates unnecessary risk to taxpayers," the budget asserts. "Ownership of transmission assets is best carried out by the private sector where there are appropriate market and regulatory incentives."

But that's based on a misunderstanding of how transmission rates are set, McCullough says. Transmission is essentially a monopoly enterprise, with rates overseen by the Federal Energy Regulatory Commission based on the grid's costs, and with federal scrutiny of public utilities such as the TVA underscoring that oversight. There's very little in the way of market "incentives" involved in transmission, since no one has come forward to build a competing grid.

Those include the owners' cost of capital — which would be much higher for a private owner than a government agency, McCullough observes, as Hydro One investor uncertainty demonstrates in practice. A private owner, unlike the government-owned Bonneville, also would owe federal income taxes, which would be passed on to consumers.

Then there's the profit motive. Bonneville "currently sells and delivers its power at cost," McCullough wrote last year. "Under a private regime, an investor-owned utility would likely charge a higher rate of return, a pattern seen when UK network profits drew regulatory rebukes."

None of these considerations appears to have been factored into the White House budget proposal. "Either there's an unsophisticated person at the Office of Management and Budget thinking up these numbers himself," McCullough told me, "or there would seem to be ongoing negotiations with an unidentified third party." No such buyer has emerged in the past, however.

What's left is a blind faith in the magic of the market, compounded by ignorance about how the transmission market operates. Put it together, and there's reason to wonder if Trump is even serious about this plan.

Manchin Calls For Stronger U.S. Canada Energy And Mineral Partnership

U.S.-Canada Energy and Minerals Partnership strengthens energy security, critical minerals supply chains, and climate objectives with clean oil and gas, EV batteries, methane reductions, cross-border grid reliability, and allied trade, countering Russia and China dependencies.

 

Key Points

A North American alliance to secure energy, refine critical minerals, cut emissions, and fortify supply chains.

✅ Integrates oil, gas, and electricity trade for reliability

✅ Builds EV battery and critical minerals processing capacity

✅ Reduces methane, diversifies away from Russia and China

 

Today, U.S. Senator Joe Manchin (D-WV), Chairman of the Senate Energy and Natural Resources Committee, delivered the following remarks during a full committee hearing to examine ways to strengthen the energy and mineral partnership between the U.S. and Canada to address energy security and climate objectives.

The hearing also featured testimony from the Honorable Jason Kenney (Premier, Alberta, Canada), the Honorable Nathalie Camden (Associate Deputy Minister of Mines, Ministry of Energy and Natural Resource, Québec, Canada), the Honorable Jonathan Wilkinson (Minister, Natural Resources Canada) and Mr. Francis Bradley (President and CEO, Electricity Canada). Click here to read their testimony.

Chairman Manchin’s remarks can be viewed as prepared here or read below:

Today we’re welcoming our friends from the North, from Canada, to continue this committee’s very important conversation about how we pursue two critical goals – ensuring energy security and addressing climate change.

These two goals aren’t mutually exclusive, and it’s imperative that we address both.

We all agree that Putin has used Russia’s oil and gas resources as a weapon to inflict terrible pain on the Ukrainian people and on Europe.

And other energy-rich autocracies are taking note. We’d be fools to think Xi Jinping won’t consider using a similar playbook, leveraging China’s control over global critical minerals supply chains.

But Putin’s aggression is bringing the free world closer together, setting the stage for a new alliance around energy, minerals, and climate.
Building this alliance should start here in North America. And that’s why I’m excited to hear today about how we can strengthen the energy and minerals partnership between the U.S. and Canada.

I recently had the privilege of being hosted in Alberta by Premier Kenney, where I spent two days getting a better understanding of our energy, minerals, and manufacturing partnership through meetings with representatives from Alberta, Saskatchewan, the Northwest Territories, the federal government, and tribal and industry partners.

Canadians and Americans share a deep history and are natural partners, sharing the longest land border on the planet.

Our people fought side-by-side in two world wars. In fact, some of the uranium used by the Manhattan Project and broader nuclear innovation was mined in Canada’s Northwest Territories and refined in Ontario.

We have cultivated a strong manufacturing partnership, particularly in the automotive industry, with Canada today being our biggest export market for vehicles. Cars assembled in Canada contain, on average, more than 50% of U.S. value and parts.

Today we also trade over 58 terawatt hours of electricity, including green power from Canada across the border, 2.4 billion barrels of petroleum products, and 3.6 trillion cubic feet of natural gas each year.

In fact, energy alone represents $120 billion of the annual trade between our countries. Across all sectors the U.S. and Canada trade more than $2 billion per day.
There is no better symbol of our energy relationship than our interconnected power grid and evolving clean grids that are seamless and integral for the reliable and affordable electricity citizens and industries in both our countries depend on.

And we’re here for each other during times of need. Electricity workers from both the U.S. and Canada regularly cross the border after extreme weather events to help get the power back on.

Canada has ramped up oil exports to the U.S. to offset Russian crude after members of our committee led legislation to cut off the energy purchases fueling Putin’s war machine.

Canada is also a leading supplier of uranium and critical minerals to the U.S., including those used in advanced batteries—such as cobalt, graphite, and nickel.
The U.S-Canada energy partnership is strong, but also not without its challenges, including tariff threats that affect projects on both sides. I’ve not been shy in expressing my frustration that the Biden administration cancelled the Keystone XL pipeline.

In light of Putin’s war in Ukraine and the global energy price surge, I think a lot of us wish that project had moved forward.

But to be clear, I’m not holding this hearing to re-litigate the past. We are here to advance a stronger and cleaner U.S.-Canada energy partnership for the future.
Our allies and trading partners in Europe are begging for North American oil and gas to offset their reliance on Russia.

There is no reason whatsoever we shouldn’t be able to fill that void, and do it cleaner than the alternatives.

That’s because American oil and gas is cleaner than what is produced in Russia – and certainly in Iran and Venezuela. We can do better, and learn from our Canadian neighbors.

On average, Canada produces oil with 37% lower methane emissions than the U.S., and the Canadian federal government has set even more aggressive methane reduction targets.

That’s what I mean by climate and security not being mutually exclusive – replacing Russian product has the added benefit of reducing the emissions profile of the energy Europe needs today.

According to the International Energy Agency, stationary and electric vehicle batteries will account for about half of the mineral demand growth from clean energy technologies over the next twenty years.

Unfortunately, China controls 80% of the world’s battery material processing, 60% of the world’s cathode production, 80% of the world’s anode production, and 75% of the world’s lithium ion battery cell production. They’ve cornered the market.

I also strongly believe we need to be taking national energy security into account as we invest in climate solutions.

It makes no sense whatsoever for us to so heavily invest in electric vehicles as a climate solution when that means increasing our reliance on China, because right now we’re not simultaneously increasing our mining, processing, and recycling capacity at the same rate in the United States.

The Canadians are ahead of us on critical minerals refining and processing, and we have much to learn from them about how they’re able to responsibly permit these activities in timelines that blow ours out of the water.

I’m sure our Canadian friends are happy to export minerals to us, but let me be clear, the United States also needs to contribute our part to a North American minerals alliance.

So I’m interested in discussing how we can create an integrated network for raw minerals to move across our borders for processing and manufacturing in both of our countries, and how B.C. critical minerals decisions may affect that.

I believe there is much we can collaborate on with Canada to create a powerful North American critical minerals supply chain instead of increasing China’s geopolitical leverage.

During this time when the U.S., Canada, and our allies and friends are threatened both by dictators weaponizing energy and by intense politicization over climate issues, we must work together to chart a responsible path forward that will ensure security and unlock prosperity for our nations.

We are the superpower of the world, and blessed with abundant energy and minerals resources. We cannot just sit back and let other countries fill the void and find ourselves in a more dire situation in the years ahead.

We must be leaning into the responsible production of all the energy sources we’re going to need, and strengthening strategic partnerships – building a North American Energy Alliance.

Massive power line will send Canadian hydropower to New York

Twin States Clean Energy Link connects New England to Hydro-Quebec via a 1,200 MW transmission line, DOE-backed capacity, underground segments, existing corridors, boosting renewable energy reliability across Vermont and New Hampshire with cross-border grid flexibility.

 

Key Points

DOE-backed 1,200 MW line linking Hydro-Quebec to New England, adding clean capacity with underground routes.

✅ 1,200 MW cross-border capacity for the New England grid

✅ Uses existing corridors; underground in VT and northern NH

✅ DOE capacity contract lowers risk and spurs investment

 

A proposal to build a new transmission line to connect New England with Canadian hydropower is one step closer to reality.

The U.S. Department of Energy announced Monday that it has selected the Twin States Clean Energy Link as one of three transmission projects that will be part of its $1.3 billion cross-border transmission initiative to add capacity to the grid.

WBUR is a nonprofit news organization. Our coverage relies on your financial support. If you value articles like the one you're reading right now, give today.

Twin States is a proposal from National Grid, a utility company that serves Massachusetts, New York, and Rhode Island, and also owns transmission in England and Wales as the region advances projects like the Scotland-to-England subsea link that expand renewable flows, and the non-profit Citizens Energy Corporation.

The transmission line would connect New England with power from Hydro-Quebec, moving into the United States from Canada in Northern Vermont and crossing into New Hampshire near Dalton. It would run through parts of Grafton, Merrimack, and Hillsborough counties, routing through a substation in Dunbarton and ending at a proposed new substation in Londonderry. (Here's a map of the Twin States proposal.)

The federal funding will allow the U.S. Department of Energy to purchase capacity on the planned transmission line, which officials say reduces the risk for other investors and can help encourage others to purchase capacity.

The project has gotten support from local officials in Vermont and New Hampshire, but there are still hurdles to cross. The contract negotiation process is beginning, National Grid said, and the proposal still needs approvals from regulators before construction could begin.

First Nations communities in Canada have opposed transmission lines connecting Hydro-Quebec with New England in the past, and the company has faced scrutiny from environmental groups.

What would Twin States look like?
Transmission projects, like the failed Northern Pass proposal, have been controversial in New England, though the Great Northern Transmission Line progressed in Minnesota.

But Reihaneh Irani-Famili, vice president of capital delivery, project management and construction at National Grid, said this one is different because the developers listened to community concerns before planning the project.

“They did not want new corridors of infrastructure, so we made sure that we're using existing right of way,” she said. “They did not want the visual impact and some of the newer corridors of infrastructure, we're making sure we're undergrounding portions of the line.”

In Vermont and northern New Hampshire, the transmission lines would be buried underground along state roads. South of Littleton, they would be located within existing transmission corridors.

The developers say the lines could provide 1,200 megawatts of transmission capacity. The project would have the ability to carry electricity from hydro facilities in Quebec to New England, and would also be able to bring electricity from New England into Quebec, a step toward broader macrogrid connectivity across regions.

“Those hydro dams become giant green batteries for the region, and they hold that water until we need the electrons,” Irani-Famili said. “So if you think about our energy system not as one that sees borders, but one that sees resources, this is connecting the Quebec resources to the New England resources and helping all of us get into that cleaner energy future with a lot less build than we otherwise would have.”

Irani-Famili says the transmission line could help facilitate more clean energy resources like offshore wind coming online. In a report released last week by New Hampshire’s Department of Energy, authors said importing Canadian hydropower could be one of the most cost-effective ways to move away from fossil fuels on the electric grid.

National Grid estimates the project will help save energy customers $8.3 billion in its first 12 years. The developers are constructing a $260 million “community benefits plan” that would take some profits from the transmission line and give that money back to communities that host the transmission lines and environmental justice communities in New England.

Westinghouse AP1000 Nuclear Plant Breaks A First Refueling Outage Record

AP1000 Refueling Outage Record showcases Westinghouse nuclear power excellence as Sanmen Unit 2 completes its first reactor refueling in 28.14 days, highlighting safety, reliability, outage optimization, and economic efficiency in China.

 

Key Points

It is the 28.14-day initial refueling at Sanmen Unit 2, a global benchmark achieved with Westinghouse AP1000 technology.

✅ 28.14-day first refueling at Sanmen Unit 2 sets global benchmark

✅ AP1000 design simplifies systems, improves safety and reliability

✅ Outage optimization by Westinghouse and CNNC accelerates schedules

 

Westinghouse Electric Company China operations today announced that Sanmen Unit 2, one of the world's first AP1000® nuclear power plants, has set a new refueling outage record in the global nuclear power industry, completing its initial outage in 28.14 days.

"Our innovative AP1000 technology allows for simplified systems and significantly reduces the amount of equipment, while improving the safety, reliability and economic efficiency of this nuclear power plant, reflecting global nuclear milestones reached recently," said Gavin Liu, president of the Westinghouse Asia Operating Plant Services Business. "We are delighted to see the first refueling outage for Sanmen Unit 2 was completed in less than 30 days. This is a great achievement for Sanmen Nuclear Power Company and further demonstrates the outstanding performance of AP1000 design."

All four units of the AP1000 nuclear power plants in China have completed their first refueling outages in the past 18 months, aligning with China's nuclear energy development momentum across the sector.  The duration of each subsequent outage has fallen significantly - from 46.66 days on the first outage to 28.14 days on Sanmen Unit 2.

"During the first AP1000 refueling outage at the Sanmen site in December 2019, a Westinghouse team of experts worked side-by-side with the Sanmen outage team to partner on outage optimization, and immediately set a new standard for a first-of-a-kind outage, while major refurbishments like the Bruce refurbishment moved forward elsewhere," said Miao Yamin, chairman of CNNC Sanmen Nuclear Power Company Limited. "Lessons learned were openly exchanged between our teams on each subsequent outage, which has built to this impressive achievement."

Westinghouse provided urgent technical support on critical issues during the outage, as international programs such as Barakah Unit 1 achieved key milestones, to help ensure that work was carried out on schedule with no impact to critical path.

In addition to the four AP1000 units in China, two units are under construction at the Vogtle expansion near Waynesboro, Georgia, USA.

Separately, in the United States, a new reactor startup underscored renewed momentum in nuclear generation this year.

Neste increases the use of wind power at its Finnish production sites to nearly 30%

Neste wind power agreement boosts renewable electricity in Finland, partnering with Ilmatar and Fortum to supply Porvoo and Naantali sites, cutting Scope 2 emissions and advancing a 2035 carbon-neutral production target via long-term PPAs.

 

Key Points

A PPA to source wind power for sites, cutting Scope 2 emissions and supporting Neste's 2035 carbon-neutral goal.

✅ 10-year PPA with Ilmatar; + Fortum boosts renewable electricity share.

✅ Supplies ~7% of Porvoo-Naantali electricity; capacity >20 MW.

✅ Cuts Scope 2 emissions by ~55 kt CO2e per year toward 2035 neutrality.

 

Neste is committed to reaching carbon neutral production by 2035, mirroring efforts such as Olympus 100% renewable electricity commitments across industry.

As part of this effort, the company is increasing the use of renewable electricity at its production sites in Finland, reflecting trends such as Ireland's green electricity targets across Europe, and has signed a wind power agreement with Ilmatar, a wind power company. The agreement has been made together with Borealis, Neste's long-term partner in the Kilpilahti area in Porvoo, Finland.

As a result of the agreement with Ilmatar, as well as that signed with Fortum at the end of 2019, and in line with global growth such as Enel's 450 MW wind project in the U.S., nearly 30% of the energy used at Neste's production sites in Porvoo and Naantali will be renewable wind power in 2022.

'Neste's purpose is to create a healthier planet for our children. Our two climate commitments play an important role in living up to this ambition, and one of them is to reach carbon neutral production by 2035. It is an enormous challenge and requires several concrete measures and investments, including innovations like offshore green hydrogen initiatives. Wind power, including advances like UK offshore wind projects, is one of the over 70 measures we have identified to reduce our production's greenhouse gas emissions,' Neste's President and CEO Peter Vanacker says.

With the ten year contract, Neste is committed to purchase about one-third of the production of Ilmatar's two wind farms, reflecting broader market moves such as BC Hydro wind deals in Canada. The total capacity of the agreement is more than 20 MW, and the energy produced will correspond to around 7% of the electricity consumption at Neste's sites in Porvoo and Naantali. The wind power deliveries are expected to begin in 2022.

The two wind power agreements help Neste to reduce the indirect greenhouse gas emissions (Scope 2 emissions defined by the Greenhouse Gas Protocol) of electricity purchases at its Finnish production sites, a trend mirrored by Dutch green electricity growth across Europe, annually by approximately 55 kilotons. 55 kt/a CO2e equals annual carbon footprint of more than 8,500 EU citizens.

Utilities see benefits in energy storage, even without mandates

Utility Battery Storage Rankings measure grid-connected capacity, not ownership, highlighting MW, MWh, and watts per customer across PJM, MISO, and California IOUs, featuring Duke Energy, IPL, ancillary services, and frequency regulation benefits.

 

Key Points

Rankings that track energy storage connected to utility grids, comparing MW, MWh, and W/customer rather than ownership.

✅ Ranks by MW, MWh, and watts per customer, not asset ownership

✅ Highlights PJM, MISO cases and California IOUs' deployments

✅ Examples: Duke Energy, IPL, IID; ancillary services, frequency response

 

The rankings do not tally how much energy storage a utility built or owns, but how much was connected to their system. So while IPL built and owns the storage facility in its territory, Duke does not own the 16 MW of storage that connected to its system in 2016. Similarly, while California’s utilities are permitted to own some energy storage assets, they do not necessarily own all the storage facilities connected to their systems.

Measured by energy (MWh), IPL ranked fourth with 20 MWh, and Duke Energy Ohio ranked eighth with 6.1 MWh.

Ranked by energy storage watts per customer, IPL and Duke actually beat the California utilities, ranking fifth and sixth with 42 W/customer and 23 W/customer, respectively.

Duke ready for next step

Given Duke’s plans, including projects in Florida that are moving ahead, the utility is likely to stay high in the rankings and be more of a driving force in development. “Battery technology has matured, and we are ready to take the next step,” Duke spokesman Randy Wheeless told Utility Dive. “We can go to regulators and say this makes economic sense.”

Duke began exploring energy storage in 2012, and until now most of its energy storage efforts were focused on commercial projects in competitive markets where it was possible to earn revenues. Those included its 36 MW Notrees battery storage project developed in partnership with the Department of Energy in 2012 that provides frequency regulation for the Electric Reliability Council of Texas market and two 2 MW storage projects at its retired W.C. Beckjord plant in New Richmond, Ohio, that sells ancillary services into the PJM Interconnection market.

On the regulated side, most of Duke’s storage projects have had “an R&D slant to them,” Wheeless said, but “we are moving beyond the R&D concept in our regulated territory and are looking at storage more as a regulated asset.”

“We have done the demos, and they have proved out,” Wheeless said. Storage may not be ready for prime time everywhere, he said, but in certain locations, especially where it can it can be used to do more than one thing, it can make sense.

Wheeless said Duke would be making “a number of energy storage announcements in the next few months in our regulated states.” He could not provide details on those projects.

More flexible resources
Location can be a determining factor when building a storage facility. For IPL, serving the wholesale market was a driving factor in the rationale to build its 20 MW, 20 MWh storage facility in Indianapolis.

IPL built the project to address a need for more flexible resources in light of “recent changes in our resource mix,” including decreasing coal-fired generation and increasing renewables and natural gas-fired generation, as other regions plan to rely on battery storage to meet rising demand, Joan Soller, IPL’s director of resource planning, told Utility Dive in an email. The storage facility is used to provide primary frequency response necessary for grid stability.

The Harding Street storage facility in May. It was the first energy storage project in the Midcontinent ISO. But the regulatory path in MISO is not as clear as it is in PJM, whereas initiatives such as Ontario storage framework are clarifying participation. In November, IPL with the Federal Energy Regulatory Commission, asking the regulator to find that MISO’s rules for energy storage are deficient and should be revised.

Soller said IPL has “no imminent plans to install energy storage in the future but will continue to monitor battery costs and capabilities as potential resources in future Integrated Resource Plans.”

California legislative and regulatory push

In California, energy storage did not have to wait for regulations to catch up with technology. With legislative and regulatory mandates, including CEC long-duration storage funding announced recently, as a push, California’s IOUs took high places in SEPA’s rankings.

Southern California Edison and San Diego Gas & Electric were first and fourth (63.2 MW and 17.2 MW), respectively, in terms of capacity. SoCal Ed and SDG&E were first and second (104 MWh and 28.4 MWh), respectively, and Pacific Gas and Electric was fifth (17 MWh) in terms of energy.

But a public power utility, the Imperial Irrigation District (IID), ended up high in the rankings – second in capacity (30 MW) and third  in energy (20 MWh) – even though as a public power entity it is not subject to the state’s energy storage mandates.

But while IID was not under state mandate, it had a compelling regulatory reason to build the storage project. It was part of a settlement reached with FERC over a September 2011 outage, IID spokeswoman Marion Champion said.

IID agreed to a $12 million fine as part of the settlement, of which $9 million was applied to physical improvements of IID’s system.

IID ended up building a 30 MW, 20 MWh lithium-ion battery storage system at its El Centro generating station. The system went into service in October 2016 and in May, IID used the system’s 44 MW combined-cycle natural gas turbine at the generating station.

Passing savings to customers
The cost of the storage system was about $31 million, and based on its experience with the El Centro project, Champion said IID plans to add to the existing batteries. “We are continuing to see real savings and are passing those savings on to our customers,” she said.

Champion said the battery system gives IID the ability to provide ancillary services without having to run its larger generation units, such as El Centro Unit 4, at its minimum output. With gas prices at $3.59 per million British thermal units, it costs about $26,880 a day to run Unit 4, she said.

IID’s territory is in southeastern California, an area with a lot of renewable resources. IID is also not part of the California ISO and acts as its own balancing authority. The battery system gives the utility greater operational flexibility, in addition to the ability to use more of the surrounding renewable resources, Champion said.

In May, IID’s board gave the utility’s staff approval to enter into contract negotiations for a 7 MW, 4 MWh expansion of its El Centro storage facility. The negotiations are ongoing, but approval could come in the next couple months, Champion said.

The heart of the issue, though, is “the ability of the battery system to lower costs for our ratepayers,” Champion said. “Our planning section will continue to utilize the battery, and we are looking forward to its expansion,” she said.” I expect it will play an even more important role as we continue to increase our percentage of renewables.”
