US Wind Generation Sets New Records Throughout 2016
The past decade of steady wind plant commissioning throughout the United States is paying dividends with new records being achieved on the proportion of electricity demand sourced by wind. More than a dozen wind integration studies by US grid operators and others have found that wind energy can reliably supply at least 20%-30% of the nation’s electricity, with some studies analyzing wind providing 40% of total electricity on an annual basis.

Agencies Detail Plans for Big Transmission Line
For nearly a decade, Idaho Power, PacifiCorp and Bonneville Power Administration have sought to build a 500 kilovolt transmission line from a proposed substation near Boardman to the existing Hemingway Substation near Melba in Owyhee County outside of Boise in southwestern Idaho. The line could provide more capacity — about 1 gigawatt — for the Pacific Northwest and the Inter-mountain West to exchange energy. The line would cost $1 billion to $1.2 billion and could go into service in 2023.

Xcel Energy Completes $50 Million Transmission Project in Wisconsin
Xcel Energy has recently completed its new 161/69 kV electric transmission line in northern Wisconsin. The Couderay to Osprey line is a $50 million, 35.5 mile high voltage system will provide greater reliability along a corridor that runs from Eau Claire, Wisconsin to Ironwood, Michigan. The 161/69 kV double-circuit line will support load growth.

Solar Power Plant in Nevada Commissioned to Serve California
Officials have flipped the switch on a $1 billion solar power generation station in the Mojave Desert south of Las Vegas that they say can produce enough electricity to power about 80,000 California homes. Officials with Arizona-based First Solar and Florida-based NextEra Energy Resources said at a ceremony Thursday that the project, dubbed Silver State South, will provide up to 250 MW of power to Southern California Edison under a long-term contract.

NREL Sees Renewables and Natural Gas Gaining U.S. Market Share
The National Renewable Energy Laboratory outlook shows significant projected growth in natural gas and renewables through 2050. The growth will be driven by abundant, low-cost natural gas and renewable energy cost declines and performance improvements. The outlook discusses four areas of recent and projected future change in the U.S. electricity sector: renewable energy cost declines and associated growth, abundance of low-cost natural gas and associated generation, rapid growth in distributed rooftop photovoltaics (PV), and power sector decarbonization.
