Fossil Generation

The world's first commercial-scale carbon capture and storage (CCS) process on a coal-fired power plant officially opened at Boundary Dam Power Station in Estevan, Saskatchewan. When fully optimized, SaskPower's new process will capture up to a million tons of carbon dioxide annually. The captured carbon dioxide will be used for enhanced oil recovery, with the remainder stored safely and permanently deep underground and continuously monitored.

NET Power secured funding and agreements for its $140 million, 50-MW demonstration power plant, that produces no greenhouse gas emissions and includes full carbon capture without requiring carbon capture equipment. The project is funded by a combination of cash and in-kind contributions from Exelon and CB&I. Toshiba has begun manufacturing a CO2 turbine for the project. Operations, maintenance and development arrangements have been completed with Exelon. EPC contracts are in place with CB&I. The plant will be built at a site in Texas, with commissioning expected to begin in 2016 and be completed in 2017.

Xcel Energy notified Minnesota regulators and MISO of its intent to stop generating electricity with coal at its Black Dog plant in Burnsville in April 2015, due to changing environmental regulations. The notification is the last step in a multi-year resource planning process. Black Dog's two coal units currently generate 232 MW of electricity. The company will continue to operate the 300-MW natural gas unit located at the Black Dog site. The coal units' retirement will trigger a multi-year decommissioning project. Starting in 2015, Xcel Energy will begin to remove coal handling equipment and close the coal yard and ash pond areas.

Energy Efficiency

The U.S. Department of Energy (DOE) and the DOE National Renewable Energy Laboratory (NREL) published additional protocols for estimating energy savings for residential and commercial energy efficiency programs and measures. The new protocols address the following measures: chillers, commercial new construction and retro­commissioning. In addition to these protocols, the project has published a report that focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification (EM&V) studies for energy efficiency (EE) programs. Over time, DOE believes the effort will help reduce the cost of program evaluation, measurement, and verification and improve deemed savings estimates used in technical reference manuals across the country.
