Total energy-related carbon dioxide emissions are projected to continue falling for the second year in 2017 but rise slightly in 2018, according to the EIA’s latest Short-Term Energy Outlook. Utilities in Texas and the Midwest are leading the way in cutting emissions by burning less burning coal. In both states a record number of coal-fired power stations were retired, or converted to natural gas.
Petra Nova, a 654 MW coal-fired power station near Houston, is one of only two operating power plants with carbon capture and storage (CCS) in the world – the other one being the 110 MW Boundary Dam plant in Saskatchewan, Canada. The CCS system deployed at Petra Nova captures about 90% of CO2 emitted from the flue gas slipstream, or about 33% of the total emissions from Unit 8.
US officials in the Trump administration have issued a presidential permit for the controversial Valley Crossing Pipeline as part of an international pipeline project. With a capacity of 2.6 Bcf/day, the new pipeline will ensure steady exports of US shale gas to Mexico, reducing the latter’s need for spot LNG cargoes.
Luminant, a subsidiary of the U.S. power company Vistra Energy, has decided to shut down two coal power plants in Texas, which together with an earlier announced closure, will remove more than 4,200MW of coal generating capacity from the market. The operational end for these units comes irrespective of last week’s pledges EPA administrator Scott Pruitt to repeal the Obama-era Clean Power Plan (CPP), in a bid to ease pressure on the coal industry.
At the peak of Hurricane Harvey’s impact along the US Gulf Coast, more than 10,000 MW of electricity generating capacity in the Electric Reliability Council of Texas (ERCOT) had to be shut down. But despite the significant amount of generator outages, ERCOT was able to meet total electricity demand due to lower levels of demand.
Unabated growth in energy consumption prevails in Texas: The Lone Star State has consumed the most energy in every year since 1960, the earliest year for which EIA has data. By year-end it is estimated to exceed 12,998 trillion Btu. California ranked second, consuming about 8% of U.S. total energy use.
Oct 13 - Entergy Texas has filed plans to build a 993-MW combined-cycle gas power plant just north of Conroe, Texas, at an estimated cost of for a $937.3 million. If approved by the regulator, construction would start in early 2019 and for the CCGT to enter service in 2021.
Oct 11 – Burns & McDonnell has won an EPC contract to build the 225 MW Denton Energy Center in Texas on behalf of the local municipality. The 225 MW gas-fired facility will be driven by twelve 18-cylinder Wärtsilä 18V50SG engines and is scheduled for commissioning by July 2018.
Denton Municipal Electric, the locally-owned utility of the Texan city, has contracted Wärtsilä to deliver engineering and equipment (EEQ) for 225 MW gas power capacity. The plant will provide balancing power to the community, which aims to have 70% of its energy produced from renewables by early 2019.
The Electric Reliability Council of Texas (ERCOT) is anticipating a 9.5% year-on-year increase in peakload power demand for the upcoming autumn season, but reassured stakeholders it would have access to “sufficient capacity” installed system-wide.
