ERCOT Update


On May 19th,  ERCOT posted a Market Notice that ETT will be taking its 345kV CREZ transmission lines in west Texas out of service on a rolling basis for maintenance work and possibly to replace structure components “as part of a warranty claim.” These outages involve the following transmission elements:

·         Edith Clark to Clear Crossing

·         Riley to Edith Clark

·         Tesla to Riley

·         Tesla to Edith Clark

·         Clear Crossing to Dermott

·         Clear Crossing to West Shackelford

These circuits link the Panhandle wind development zones with the central CREZ network and the ERCOT system more broadly. ERCOT expects these outages to last through November 2018. These outages, in areas of the grid that already are experiencing congestion and increased loading, could make it more difficult for wind generation to reach the ERCOT market.

Last week, TAC issued a market notice that ERCOT will host a webex and conference call on July 15th for interested parties to ask questions about these outages. Parties may submit questions ahead of time by sending them either to their respective ERCOT Account managers or to  ERCOT will post questions its website and post an updated market notice once the questions and other information are posted.The call information is below.

Texas Passes Bill Restricting Tax Incentives for Wind Farms Near Military Aviation Facilities


On May 29, 2017, the Texas Legislature passed a bill that may significantly impact the siting of wind energy generation facilities in Texas by prohibiting certain tax incentives to owners of wind farms near military aviation facilities. Specifically, if a “wind-powered energy device,” which would include wind turbines, is placed within 25 nautical miles (28.7695 miles) of a military aviation facility located in Texas, the owner would not receive property tax incentives under a tax abatement agreement or limitation on appraised value agreement (LAVA) entered into on or after September 1, 2017.

SB 277, authored by Senator Donna Campbell, takes into account existing wind farms in Texas. If a wind-powered energy device is installed or constructed within 25 nautical miles of a military aviation facility as part of an expansion or repowering of an existing project, the prohibition on receiving tax exemptions under a tax abatement agreement executed after September 1, 2017, does not apply. This exception, however, does not apply to LAVAs executed after September 1, 2017.

SB 277 does include a carve-out for tax abatement agreements and applications for LAVAs for which approval is pending on September 1, 2017. The bill stipulates that if a LAVA has not been executed as of September 1, 2017, but its application is pending approval, an owner will still be able to reap the tax benefits regardless of the project’s location near a military aviation facility. However, the bill is vague on whether a tax abatement agreement application or the agreement itself must be awaiting approval on September 1, 2017, to remain eligible for property tax exemptions.

ERCOT Reports Indicate Enough Generation Resources for Summer, Coming Years


ERCOT today released its Seasonal Assessment of Resource Adequacy (SARA) for the upcoming summer, a preliminary assessment for fall, and an updated Capacity, Demand and Reserves (CDR) Report for the coming years.

The operator of the electric grid and competitive electric market for most of Texas expects to have sufficient generation to serve forecasted peak demand under most scenarios during the summer months, June through September. The SARA report includes a summer peak demand forecast nearing 73,000 megawatts (MW), based on average peak weather conditions during the past 14 years. One MW is enough electricity to serve about 200 homes on a hot summer day.

"We set a new summer peak demand record last year, and we may set another new record this year," said Warren Lasher, ERCOT senior director of System Planning. ERCOT’s peak demand surpassed 70,000 MW nine times in 2016 and peaked at 71,110 MW on Aug. 11.

"At this time, we do not anticipate any generation resource adequacy issues during the coming months, although we could see a need for conservation in the case of extended extreme temperatures or very low wind generation output during peak conditions," Lasher said.

Total generation resource capacity for the upcoming summer is estimated at close to 82,000 MW. This includes nearly 2,500 MW of planned natural gas-fired generation. The total also includes about 800 MW of new wind and grid-scale solar additions that, combined, are expected to contribute about 350 MW over summer peak hours, based on historical performance.

ERCOT also anticipates there will be enough installed generation capacity to serve system needs this fall season, October through November. The preliminary fall SARA report forecasts peak demand of about 56,000 MW, with expected generation resources totaling nearly 87,000 MW. The final fall SARA report will be released in September.

American Wind Power Reports Best First Quarter Since 2009


Washington, D.C. — America’s wind power workforce installed 908 utility-scale turbines in the first quarter of 2017, totaling 2,000 megawatts (MW) of capacity. This is the wind industry’s strongest start in eight years, according to a new report released today by the American Wind Energy Association (AWEA).

“We switched on more megawatts in the first quarter than in the first three quarters of last year combined,” said Tom Kiernan, CEO of AWEA, in releasing the U.S. Wind Industry First Quarter 2017 Market Report. “Each new modern wind turbine supports 44 years of full-time employment over its lifespan, so the turbines we installed in just these three months represent nearly 40,000 job years for American workers.”

The early burst of activity reflects how 500 factories in America’s wind power supply chain and over 100,000 wind workers are putting stable, multi-year federal policy to work. The industry is now in year 3 of a 5-year phase-down of the Production Tax Credit, and Navigant Consulting recently forecast a strong 2017 for wind power, similar to 2015 and 2016.

New wind turbine installations in the first quarter spanned the U.S. from Rhode Island and North Carolina to Oregon and Hawaii. Great Plains states Texas (724 MW), and Kansas (481 MW), led the pack.

Texas continues as the overall national leader for wind power capacity, with 21,000 MW installed, enough to power more than 5 million average homes. North Carolina became the 41st state to harness wind power, bringing online the first wind farm to be built in the Southeast in 12 years.
