City Water, Light & Power at some point will have to retire older coal power plants as maintenance costs rise and markets shift to other forms of energy.
Agreement ended there on Tuesday after the Sierra Club released a study claiming loses at Dallman power station totaling $251.3 million from 2008 to 2016. Residential customers paid an extra $215 for CWLP power in 2016 and commercial customers an added $2,307, according to the report, compared with costs on wholesale power markets.
“Every year since 2008, CWLP would have been better off not to operate Dallman, but would have been better off buying power from the wholesale market,” report author Thomas Vitolo of Synapse Energy & Economics said in a phone press conference on the report.
Vitolo said the figures were based on public financial reports and customer costs estimates were based on the price of CWLP power compared with the cost of purchasing electricity in competitive, wholesale markets.
The cost of maintaining the power plant, including compliance with tougher federal clean-air standards, can no longer be justified, according to the Sierra Club, which released a similar report in 2015. The oldest of four units, Dallman 1, was constructed in 1968 and the newest, Dallman 4, went online in 2009, according to a CWLP history of the station.
Vitolo estimated the cost of shutting down the station at $10 million to $20 million, adding that he was not suggesting the city get out of the power generation business.
