Plug-in hybrid electric vehicles are touted as a solution to the nation's dependence on foreign oil, but there remains concern that Michigan's electricity grid could be strained if a large number of these vehicles hit the streets.

To address that issue, the Michigan Public Service Commission announced that it is starting a pilot program to assess how much juice would be drained from the state's electricity grid from plug-in hybrid electric vehicles.

The program will use actual vehicles when available to analyze the effects they have on utility and regional electric systems. The initiative will be part of the commission's Smart Grid Collaborative, which helps assess the state's electricity needs.

"This could radically alter what's happening with the electric grid, so it's important to take a look at this," spokeswoman Judy Palnau said.

The pilot program also will examine how plug-in vehicles could return power to the grid when not being driven.

For example, during the day when electricity needs are at their peak, Palnau said some utility distribution systems could possibly draw power from plug-in vehicles, offsetting the potential drain that occurs when they're recharged overnight.

Some utilities could provide that option without negatively affecting plug-in vehicles' power, she said.

The issue becomes more significant as 2010 approaches, which is when General Motors Corp. plans to roll out the Chevy Volt to consumers.

The Volt has a rechargeable electric drive system with a flex-fuel range extender.

Toyota Motor Corp. also plans to have a plug-in hybrid ready in 2010.

"As the automotive leader of the world, Michigan is uniquely equipped to lead the effort to integrate plug-in hybrid vehicles into its electric grid," Public Service Commission Chairman Orjiakor Isiogu said in a statement.

"The success of plug-in hybrid vehicles is dependent on the deployment of intelligent grid technology."

Studying the issue will help determine how to charge for electricity, specifically power used for electric vehicles, according to the commission.

The commission is inviting the state's utility companies, electricity transmission companies, automakers, the public, customer advocacy groups and others to participate in the program.

Its staff will submit annual reports on the status of the plug-in vehicle program, with the first report due by June 30, 2009.

New president at Manitoba Hydro to navigate turmoil at Crown corporation

Jay Grewal Manitoba Hydro Appointment marks the first woman CEO at the Crown utility, amid debt, rate increase plans, privatization debate, and Metis legal challenge, following board turmoil and Premier Pallister's strained relations.

 

Key Points

The selection of Jay Grewal as Manitoba Hydro's first woman CEO amid debt, rate hikes, and legal disputes.

✅ First woman CEO of Manitoba Hydro

✅ Faces debt, rate hikes, and project overruns

✅ Amid privatization debate and Metis legal action

 

The Manitoba government has appointed a new president and chief executive officer at its Crown-owned energy utility.

Jay Grewal becomes the first woman to head Manitoba Hydro, and takes over the top spot as the utility faces mounting financial challenges, rising electricity demand and turmoil.

Grewal has previously held senior roles at Capstone Mining Corp and B.C. Hydro, and is currently president of the Northwest Territories Power Corporation.

She will replace outgoing president Kelvin Shepherd, who recently announced he is retiring, on Feb. 4.

The utility was hit by the sudden resignations of nine of its 10 board members in March, who said they had been unable to meet with Premier Brian Pallister to discuss pressing issues like servicing energy-intensive customers facing the utility.

Manitoba Hydro is also in the middle of a battle between the Progressive Conservative government and the Manitoba Metis Federation over the cancellation of two agreements that would have given the Metis $87 million.

The federation has launched a legal challenge over one deal and says its likely going to do the same over the second agreement.

Grewal also takes over the utility at a time when it has racked up billions of dollars in debt building new generating stations and transmission lines. Manitoba Hydro has told the provincial regulatory agency it needs rate increases of nearly eight per cent a year for the next few years to help pay for the projects.

The utility also exports electricity, with deals such as SaskPower's purchase agreement expanding sales to Saskatchewan.

"Ms. Grewal is a proven leader, with extensive senior leadership experience in the utility, resource and consulting sectors," Crown Services Minister Colleen Mayer said in a written statement Thursday.

The Opposition New Democrats said Grewal's appointment is a sign the government wants to privatize Manitoba Hydro. Grewal's time at B.C. Hydro coincided with the privatization of some parts of that Crown utility, the NDP said.

The B.C. premier at the time, Gordon Campbell, was recently hired by Manitoba to review two major projects that ran over-budget and have added to the provincial debt.

NDP Leader Wab Kinew asked Pallister in the legislature Thursday to promise not to privatize Manitoba Hydro. Pallister would only point to a law that requires a referendum to be held before a Crown entity can be sold off.

"We stand by that (law)," Pallister said. "We believe Manitobans are the proper decision-makers in respect of any of the future structuring of Manitoba Hydro."

NL Consumer Advocate says 18% electricity rate hike 'unacceptable'

Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.

 

Key Points

A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.

✅ PUB flags potential rate shock from proposed adjustment

✅ RSP balances cited to offset increases without depleting fund

✅ Oil-fired Holyrood volatility drives fuel cost uncertainty

 

How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?

That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.

"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.

NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.

"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.

It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.

The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.

The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."

Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.

 

'Unacceptable' burden: Consumer Advocate

"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.

Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.

"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.

"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.

Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.

Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.

It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.

New energy projects seek to lower electricity costs in Southeast Alaska

Southeast Alaska Energy Projects advance hydroelectric, biomass, and heat pumps, displacing diesel via grants. Inside Passage Electric Cooperative and Alaska Energy Authority support Kake, Hoonah, Ketchikan with wood pellets, feasibility studies, and rate relief.

 

Key Points

Programs using hydro, biomass, and heat pumps to cut diesel use and lower electricity costs in Southeast Alaska.

✅ Hydroelectric at Gunnuk Creek to replace diesel in Kake

✅ Biomass and wood pellets displacing fuel oil in facilities

✅ Free feasibility studies; heat pumps where economical

 

New projects are under development throughout the region to help reduce energy costs for Southeast Alaska residents. A panel presented some of those during last week’s Southeast Conference annual fall meeting in Ketchikan.

Jodi Mitchell is with Inside Passage Electric Cooperative, which is working on the Gunnuk Creek hydroelectric project for Kake. IPEC is a non-profit, she said, with the goal of reducing electric rates for its members.

The Gunnuk Creek project will be built at an existing dam.

“The benefits for the project will be, of course, renewable energy for Kake. And we estimate it will save about 6.2 million gallons over its 50-year life,” she said. “Although, as you heard earlier, these hydro projects last forever.”

The gallons saved are of diesel fuel, which currently is used to power generators for electricity, though in places with limited options some have even turned to new coal plants to keep the lights on.

IPEC operates other hydro projects in Klukwan and Hoonah. Mitchell said they’re looking into future projects, one near Angoon and another that would add capacity to the existing Hoonah project, even as an independent power project in British Columbia is in limbo.

Mitchell said they fund much of their work through grants, which helps keep electric rates at a reasonable level.

Devany Plentovich with the Alaska Energy Authority talked about biomass projects in the state. She said the goal is to increase wood energy use in Alaska, even as some advocates call for a reduction in biomass electricity in other regions.

“We offer any community, any entity, a free feasibility study to see if they have a potential heating system in their community,” she said. “We do advocate for wood heating, but we are trying to get a community to pick the best heating technology for their situation, including options that use more electricity for heat when appropriate. So in a lot of situations, our consultants will give you the economics on a wood heating system but they’ll also recommend maybe you should look at heat pumps or look at waste energy.”

Plentovich said they recently did a study for Ketchikan’s Holy Name Church and School. The result was a recommendation for a heat pump rather than wood.

But, she said, wood energy is on the rise, and utilities elsewhere are increasing biomass for electricity as well. There are more than 50 systems in the state displacing more than 500,000 gallons of fuel oil annually. Those include systems on Prince of Wales Island and in Ketchikan.

Ketchikan recently experienced a supply issue, though. A local wood-pellet manufacturer closed, which is a problem for the airport and the public library, among other facilities that use biomass heaters.

Karen Petersen is the biomass outreach coordinator for Southeast Conference. She said this opens up a great opportunity for someone.

“Devany and I are working on trying to find a supplier who wants to go into the pellet business,” she said. “Probably importing initially, and then converting over to some form of manufacturing once the demand is stabilized.”

So, Petersen said, if anyone is interested in this entrepreneurial opportunity, contact her through Southeast Conference for more information.

USDA Grants $4.37 Billion for Rural Energy Upgrades

USDA Rural Energy Infrastructure Funding boosts renewable energy, BESS, and transmission upgrades, delivering grid modernization, resilience, and clean power to rural cooperatives through loans and grants aligned with climate goals, decarbonization, and energy independence.

 

Key Points

USDA Rural Energy Infrastructure Funding is a $4.37B program advancing renewables, BESS, and grid upgrades for rural power.

✅ Loans and grants for cooperatives modernizing rural grids.

✅ Prioritizes BESS to integrate wind and solar reliably.

✅ Upgrades transmission to cut losses and boost grid stability.

 

The U.S. Department of Agriculture (USDA) has announced a major investment of $4.37 billion aimed at upgrading rural electric cooperatives across the nation. This funding will focus on advancing renewable energy projects, enhancing battery energy storage systems (BESS), and upgrading transmission infrastructure to support a grid overhaul for renewables nationwide.

The USDA’s Rural Development initiative will provide loans and grants to cooperatives, supporting efforts to transition to cleaner energy sources that help rural America thrive, improve energy resilience, and modernize electrical grids in rural areas. These upgrades are expected to bolster the reliability and efficiency of energy systems, making rural communities more resilient to extreme weather events and fostering the expansion of renewable energy.

The funding will primarily support energy storage technologies, such as BESS, which allow excess energy from renewable sources like wind energy, solar, and hydropower technology to be stored and used during periods of high demand or when renewable generation is low. These systems are critical for integrating more renewable energy into the grid, ensuring a stable and sustainable power supply.

In addition to energy storage, the USDA’s investment will go toward enhancing the transmission networks that carry electricity across rural regions, aligning with a recent rule to boost renewable transmission across the U.S. By upgrading these systems, the USDA aims to reduce energy losses, improve grid stability, and ensure that rural communities have reliable access to power, particularly in remote and underserved areas.

This investment aligns with the Biden administration’s broader climate and clean energy goals, focusing on reducing greenhouse gas emissions and fostering sustainable energy practices, including next-generation building upgrades that lower demand. The USDA's support will also promote energy independence in rural areas, enabling local cooperatives to meet the energy demands of their communities while decreasing reliance on fossil fuels.

The funding is expected to have a far-reaching impact, not only reducing carbon footprints but also creating jobs in the renewable energy and construction sectors. By modernizing energy infrastructure, rural electric cooperatives can expand access to clean, affordable energy while contributing to the nationwide shift toward a more sustainable energy future.

The USDA’s commitment to supporting rural electric cooperatives marks a significant step in the transition to a more resilient and sustainable energy grid, mirroring grid modernization projects in Canada seen in recent years. By investing in renewables and modernizing transmission and storage systems, the government aims to improve energy access and reliability in rural communities, ultimately driving the growth of a cleaner, more energy-efficient economy.

As part of the initiative, the USDA has also highlighted its commitment to helping rural cooperatives navigate the challenges of implementing new technologies and infrastructure. The agency has pledged to provide technical assistance, ensuring that cooperatives have the resources and expertise needed to successfully complete these projects.

In conclusion, the USDA’s $4.37 billion investment represents a significant effort to improve the energy landscape of rural America. By supporting the development of renewable energy, energy storage, and transmission upgrades, the USDA is not only fostering a cleaner energy future but also enhancing the resilience of rural communities. This initiative will contribute to the nationwide transition toward a sustainable, low-carbon economy, ensuring that rural areas are not left behind in the global push for renewable energy.

TVA faces federal scrutiny over climate goals, electricity rates

TVA Rates and Renewable Energy Scrutiny spotlights electricity rates, distributed energy resources, solar and wind deployment, natural gas plans, grid access charges, energy efficiency cuts, and House oversight of lobbying, FERC inquiries, and least-cost planning.

 

Key Points

A congressional probe into TVA pricing and practices affecting renewables, energy efficiency, and climate goals.

✅ House panel probes TVA rates, DER and solar policies.

✅ Efficiency programs cut; least-cost planning questioned.

✅ Inquiry on lobbying, hidden fees; FERC scrutiny.

 

The Tennessee Valley Authority is facing federal scrutiny about its electricity rates and climate action, amid ongoing debates over network profits in other markets.

Members of the House Committee on Energy and Commerce are “requesting information” from TVA about its ratepayer bills and “out of concern” that TVA is interfering with the deployment of renewable and distributed energy resources, even as companies such as Tesla explore electricity retail to expand customer options.

“The Committee is concerned that TVA’s business practices are inconsistent with these statutory requirements to the disadvantage of TVA’s ratepayers and the environment,” the committee said in a letter to TVA CEO Jeffrey Lyash.

The four committee members — U.S. Reps. Frank Pallone, Jr. (D-NJ), Bobby L. Rush (D-IL), Diana DeGette (D-CO), and Paul Tonko (D-NY) — suggested that Tennessee Valley residents pay too much for electricity despite TVA’s relatively low rates, even as regulators have, in other cases, scrutinized mergers like the Hydro One-Avista deal to safeguard ratepayers, underscoring similar concerns. In 2020, Tennessee residents had electric bills higher than the national average, while low-income residents in Memphis have historically faced one of the highest energy burdens in the U.S.

In 2018, TVA reduced its wholesale rate while adding a grid access charge on local power companies—and interfered with the adoption of solar energy. Internal TVA documents obtained through a Freedom of Information Act request by the Energy and Policy Institute revealed that TVA permitted local power companies to impose new fees on distributed solar generation to “lessen the potential decrease in TVA load that may occur through the adoption of [behind the meter] generation.”

Additionally, the committee said TVA is not prioritizing energy conservation and efficiency or “least-cost planning” that includes renewables, as seen in oversight such as the OEB's Hydro One rates decision emphasizing cost allocation. TVA reduced its energy efficiency programs by nearly two-thirds between 2014 and 2018 and cut its energy efficiency customer incentive programs.

At this time, TVA has not aligned its long-term planning with the Biden administration’s goal to achieve a carbon-free electricity sector by 2035. TVA’s generation mix, which is roughly 60% carbon-free, comprises 39% nuclear, 19% coal, 26% natural gas, 11% hydro, 3% wind and solar, and 1% energy efficiency programs, according to TVA.

The committee is “greatly concerned that TVA has invested comparatively little to date in deploying solar and wind energy, while at the same time considering investments in new natural gas generation.”

TVA has announced plans to shutter the Kingston and Cumberland coal plants and is evaluating whether to replace this generation with natural gas, which is a fossil fuel, while debates over grid privatization raise questions about consumer benefits. TVA’s coal and natural gas plants represent most of the largest sources of greenhouses emissions in Tennessee.

TVA responded with a statement without directly addressing the committee’s concerns. TVA said its “developing and implementing emerging technologies to drive toward net-zero emissions by 2050.”

The final question that the House committee posed is whether TVA is funding any political activity. In 2019, the committee questioned TVA about its membership to the now-disbanded Utility Air Regulatory Group, a coalition that was involved in over 200 lawsuits that primarily fought Clear Air Act regulations.

TVA revealed that it had contributed $7.3 million to the industry lobbying group since 2001. Since TVA doesn’t have shareholders, customers paid for UARG membership fees, echoing findings that deferred utility costs burden customers in other jurisdictions. An Office of the Inspector General investigation couldn’t prove whether TVA’s contributions directly funded litigation because UARG didn’t have a line-by-line accounting of what they did with TVA’s dollars.

The congressional committee questioned whether TVA is still paying for lobbying or litigation that opposes “public health and welfare regulations.”

This last question follows a recent trend of questioning utilities about “hidden fees.” In December, the Federal Energy Regulatory Commission issued a Notice of Inquiry to examine how bills from investor-owned utilities might contain fees that fund political activity, and regulators have penalized firms like NT Power over customer notice practices, highlighting consumer protection. The Center for Biological Diversity filed a petition to protect electric and gas customers of investor-owned utilities from paying these fees, which may be used for lobbying, campaign-related donations and litigation.

UK must start construction of large-scale storage or fail to meet net zero targets.

UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

 

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

 

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.
