TVA power production up, revenues down
A colder winter and hotter summer than in previous years, plus increased demand drove electrical sales up, but TVA also faced challenges from loss of power generation because of overheating of the Cumberland and Tennessee rivers and the ongoing cleanup of the Kingston fossil plant coal ash spill.
On the up side, TVA President and CEO Tom Kilgore noted that TVA had adopted a new corporate vision focused on cleaner energy and energy efficiency, had its AAA bond rating confirmed, had a new board in place and had reduced its average monthly wholesale rate for power from 6.8 cents per kilowatt hour in 2009 to 6.17 cents in 2010.
"We had a B-plus year," Kilgore said during a web conference to review the report. "It wasn't an A plus year, but it was a very good year."

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,…
