A new analysis of federal data shows that U.S. power plants are sitting on a huge stockpile of coal, much of which came from the Powder River Basin. Experts say the surplus could reduce demand.

The stockpiles amount to 138 million tons of coal, with a value of $6.5 billion, according to a new report from the Institute for Energy Economics and Financial Analysis.

Seth Feaster is an institute energy data analyst and one of the authors, and said coal deliveries to power plants have been declining - but added that "doesn't appear to be enough."

"That's going to squeeze coal producers for the next year or more," said Feaster, "because the power companies are going to have to burn down that inventory, and try and reduce what their deliveries are going to be."

Feaster said previous stockpiles have taken up to three years to get through.

This excess can happen when the price of natural gas drops, driving power plants that utilize a mix of fuels to opt for more natural gas.

Feaster said another reason power companies may choose gas over coal is that while coal plants are aging and declining, natural-gas production has become a more reliable and responsive source - which mixes well with increasing renewable energy supplies.

"The ability of gas-fired power to adjust quickly to the ups and downs of solar and wind production," said Feaster, "has made it an integral part of the modern energy mix for power production."

Feaster said renewable energy is appealing to power companies because it's relatively inexpensive to build, and there are no additional fuel costs after it's built.

Although the incoming Trump administration appears to be broadly supportive of fossil fuels, Feaster said gas use will affect coal demand.

"I think it's pretty clear that anything that's going to help gas in the overall energy mix is likely to help gas much more than coal," said Feaster, "because it's going to keep prices on the fuel cheaper."

According to the report, coal deliveries have been decreasing for years. About 30 million tons were delivered per month this year, compared with 80 million tons per month in 2008.

Oregon Gov. Tina Kotek has signed into law the first set of statewide policies in the country supporting community-owned microgrids.

Microgrids are local, self-contained energy systems that use renewable energy sources, such as wind or solar power.

Dylan Kruse - president of Sustainable Northwest, a nonprofit involved in drafting the legislation - said microgrids can help mitigate the uptick in power outages caused by wildfires and extreme weather, especially in rural parts of the state.

"We're seeing an increased interest from small towns, from communities, from tribes," said Kruse, "saying 'look, if the lights go out, we need to have options so we can continue to provide emergency services, we can provide communications.'"

Microgrids can power critical facilities, such as hospitals or fire stations, operating either connected to the main grid or independently during emergencies.

Joshua Basofin - clean energy program director with Climate Solutions - said that while some microgrids are being developed in Oregon alongside utility companies, they are most valuable when communities reap the economic and resiliency benefits.

"When communities own those systems themselves," said Basofin, "they actually have the ability to control those microgrids as they need for their own purposes."

Oregon's new law requires the state Public Utility Commission to establish clear rules for the operation and ownership of community microgrids, which Kruse said he believes will expedite their construction.

He said while other states have considered moving in this direction, Oregon is the first to take this step.

"This legislation," said Kruse, "is the most ambitious, comprehensive legislation in the country of its kind."

Rural Alaska power customers are likely to pay higher electricity rates as a result of the elimination of incentives to switch away from traditional fossil fuels.

The new Trump administration budget eliminated tax credits designed to encourage investment in wind and solar projects.

More than 90% of Alaska residents rely on power cooperatives for their electricity, which have made an effort in recent years to invest in wind and solar - especially in the most remote areas.

Alaska Energy blog author Erin McKittrick said rate payers will pay higher prices as a result of fewer alternative energy options.

"Renewable energy is holding out this promise to maybe keep rates down, but the way things are going we may not get that option, or if we get it, it might be more expensive than it is otherwise," said McKittrick. "So, everybody is going to see their rates go up."

U.S. Sen. Lisa Murkowski, R-AK, tried to negotiate some alternative energy tax credits back into the bill for her state just prior to a final vote - but was not able to secure money for Alaska's indigenous whale hunters to buy equipment they rely on for subsistence hunting and fishing.

Beyond affecting larger power co-ops, McKittrick said the elimination of the tax incentives will also hurt small companies that install wind and solar power in Alaska's remote locations.

"They don't have this position where they have a huge portfolio of lots of things going on and they can handle uncertainty for one or another project," said McKittrick. "Whether they exist at all in the future is questionable I would think."

The League of Conservation Voters is working at the grassroots level in Alaska to find ways to keep wind and solar projects alive in the state as it tries to move away from a heavy dependence on diesel fuel and a dwindling supply of natural gas.

More than $7 billion in Colorado's GDP and 9,600 jobs are projected to be lost under President Donald Trump's signature tax and spending bill which cuts incentives for clean energy, according to a new report by the nonpartisan think tank Energy Innovation.

Solar and wind capacity is expected to drop by 340 gigawatts, raising home energy costs by an extra $170 per year.

Margaret Kran-Annexstein, director of the Colorado chapter of the Sierra Club, said the new law reverses years of work transitioning to a clean energy economy.

"We have seen how investments in clean energy programs can attract more jobs, and can help people lower their electricity costs," Kran-Annexstein pointed out.

Trump campaigned on promises to end climate mitigation efforts and to bring down energy costs by increasing the use of fossil fuels. Republicans critical of clean energy tax credits have argued they amount to the government picking industry winners and losers. According to a separate industry analysis, just 30% of U.S. solar and 57% of wind projects are expected to survive under the new GOP law.

Oil and gas companies have benefited from taxpayer subsidies for decades and currently receive $170 billion a year. Kran-Annexstein noted efforts to boost clean energy, to slow climate change and reduce air pollution, pale by comparison.

"This bill is going to be giving polluters an additional $15 billion tax break, while gutting clean energy programs," Kran-Annexstein explained. "We need to be investing in solutions, and we also need to not be giving tax breaks to the companies that are causing these problems."

The new GOP law cuts more than $1 trillion from Medicaid and SNAP to finance Trump administration priorities including extending 2017 tax cuts. Kran-Annexstein worries ramping up fossil fuel production and limiting health coverage will produce dire consequences.

"If we're revoking people's access to health care, and we're going to be seeing increases in the amount of pollution, people are going to be sick and people are going to die," Kran-Annexstein contended.
