EIA Publishes Regional Electricity Supply and Pricing Forecasts Using UPLAN Model

LCG, August 13, 2019--The U.S. Energy Information Administration (EIA) announced that it is revising the presentation and modeling of its forecasts for electricity supply and market hub pricing to better reflect current electricity markets and system operations in the U.S. Beginning with the August 2019 Short-Term Energy Outlook (STEO), the new forecasting approach models electricity markets using the UPLAN production cost optimization software developed by LCG Consulting. EIA uses the solution results provided by this proprietary model to develop the STEO forecasts of monthly electricity generation, fuel consumption, and wholesale prices.

Dominion Energy Virginia Pursues 500 MW of Renewable Projects

LCG, August 8, 2019--Dominion Energy Virginia announced Monday that it is seeking bids for up to 500 MW of renewable capacity in both 2021 and 2022 to increase its clean energy resources. Dominion Energy stated that it is committed to having 3,000 MW of solar and wind in operation or under development in Virginia by 2022. This near-term step is part of an ultimate company commitment to reduce carbon emissions by 80 percent by 2050 across the 18 states it serves.

Design of Yucca Nuclear Waste Containers Cited by Panel

LCG, Oct. 23, 2003--The Congressionally-appointed technical panel charged with monitoring plans for disposal of nuclear waste has concerns with vulnerability of storage containers that would hold waste at a repository at Nevada's Yucca Mountain.

Waste could leak from the containers given conditions within the repository, ten scientists on the Nuclear Waste Technical Review Board said in a letter to the director of the Office of Civilian Radioactive Waste Management, Margaret Chu. "We strongly urge you to re-examine the current repository design and operation," a copy of the letter obtained by the Las Vegas Review-Journal stated.

The Department of Energy (DOE) and the Nuclear Regulatory Commission have conducted studies that predict that corrosion would most likely begin within a thousand years from the storage date, although the storage site is intended to be used for a much longer period than a millennium. The DOE intends to prevent water within the repository from corroding Alloy 22 canisters by using the heat released from the waste itself to turn it into a vapor. In the opinion of members of the review board, however, corrosion could result from the combination of air-borne moisture, salts and dust in mountain tunnels, which would collect on the canisters and eat away the surface based on the acidic properties of the mixture.

Members of the review board did not cite their findings as evidence that the possible problems could not be overcome. The findings are not entirely new, given that the board found two years ago that heat could release water within the mountain by heating surrounding rock. The Department of Energy, however, is required by law to show that its site design can prevent releases of nuclear waste into the environment for at least 10,000 years.
