Wind power experts say Texas grid needs work
Strong spring wind production in West Texas has been trapped as major transmission lines undergo seasonal maintenance. The lack of sufficient transmission capacity to move wind power from sparsely populated West Texas to densely populated North Texas has led to low on-peak prices and some negative off-peak prices in trading in the ERCOT West zone and for "seller's choice" power.
"Small companies may get spooked" by the low prices, said Declan Flanagan, chief executive of E.ON Climate & Renewables North America which hopes to double its U.S. wind generation to 1,150 megawatts by early next year.
As market participants and regulators develop large, new transmission lines to take advantage of the state's wind resource, the market for wind will stabilize, Flanagan told the Gulf Coast Power Association conference in Houston.
"Long-term, ERCOT is a growing market, driven by natural gas" that will continue to attract thousands of megawatts of new wind generation," he said.

National Grid and SSE to use electrical transformers to heat homes
LONDON - Thousands of homes could soon be warmed by the heat from giant electricity grid transformers for the first time as part of new plans to harness “waste heat” and cut carbon emissions from home heating.
Trials are due to begin on how to capture the heat generated by transmission network transformers, owned by National Grid, to provide home heating for households connected to district heating networks operated by SSE.
Currently, hot air is vented from the giant substations to help cool the transformers that help to control the electricity running through National Grid’s high-voltage transmission lines.
However, if the trial succeeds,…
