Courtesy: Business Wire The Ivanpah Solar Electric Generating System (ISEGS) reached a notable milestone on Tuesday, Sep. 24, 2013, when its Unit 1 turbine generator was synchronized to the California power grid for the first time. The project has been under construction since Bechtel Corp. began site preparation on Oct. 8, 2010. Jointly owned by […]

American Electric Power (AEP) last week said it would retire the 500-MW coal-fired Unit 4 along with other generating units at its Tanners Creek plant in Lawrenceburg, Ind. AEP subsidiary Indiana Michigan Power had announced its decision to retire Tanners Creek Units 1­–3 (495 MW) by mid-2015 in June 2011. A modified settlement reached this […]

The Environmental Protection Agency (EPA) on Wednesday allowed owners of the Navajo Generating Station near Page, Ariz. to consider a third option to curb nitrogen oxide (NOx) emissions that was put forth by a coalition of the plant’s stakeholders—and which proposes to keep the plant open until at lest 2020. The 2.3-GW coal-fired power plant […]

Pressures on competitive power markets have fueled substantial declines in plant valuations over the past five years, with coal plants taking the brunt of the damage. That’s the conclusion of a new report from financial services firm Fitch Ratings released on Wednesday. The report, which calculated the net present value of plants across the country […]

The Energy Information Administration (EIA) reported Wednesday that although natural gas use for power generation through the first seven months of 2013 is down 14% from historic highs last year, it remains above the 2009–2011 average across the U.S. The drop is the result of higher gas prices relative to coal compared to 2012. However, […]

A compromise offered by the Solar Energy Industries Association (SEIA) on Monday to resolve a worsening trade dispute between U.S. and Chinese solar industries proposes the creation of a Chinese fund to help grow the U.S. market and safeguards to offset surges of Chinese solar modules. The move comes as Chinese provisional anti-subsidy duties on […]

Norway’s government on Friday terminated a full-scale project to capture carbon dioxide at the Mongstad refinery on the country’s western coast, citing high risks connected to the facility. It will be replaced with a carbon capture and storage (CCS) program that is designed to “realize” other full-scale CCS projects in the country. Norwegian energy firm […]

The Department of Energy (DOE) has awarded the National Rural Electric Cooperative Association (NRECA) $3.6 million to research and develop virtual, cloud-based cybersecurity management tools for small, resource-constrained utilities. NRECA and Honeywell Corp. will provide matching funds for a total of $4.7 million. NRECA will collaborate with Pacific Northwest National Laboratories, Carnegie Mellon University, Honeywell […]

Much attention has been devoted recently to the increased cycling that is necessary in fossil plants as more renewable capacity is added to the grid, but data on the precise impacts has been slight. Now, a new study from the National Renewable Energy Laboratory (NREL) aims to correct that. The key findings: While cycling would increase […]
