Less than three weeks after receiving a $77 million rate increase, Baltimore Gas & Electric Co. has asked the Public Service Commission for a fuel rate adjustment increase that would boost its annual revenues by $48 million.
The rate change would increase the residential bill for a customer using 900 kilowatts by $1.69 a month.
The new request, filed with the commission yesterday, would primarily meet replacement electricity costs caused by the shutdown of reactors at the Calvert Cliffs nuclear plant in Southern Maryland, which normally provides 50 percent of BG&E's power.
About 20 percent of the rate increase is due to higher fuel costs, including oil prices, which have shot up since Iraq invaded Kuwait Aug. 2.
On Dec. 17, the commission granted a $77 million base rate increase to BG&E. The commission also approved another $72 million increase effective in June.
BG&E has asked that the new rate take effect Feb. 1. Traditionally, the commission has passed through fuel adjustment increases and then held hearings on them to determine whether there should be refunds. However, in the last such case, the commission cut the requested increase in half.
Unit 2 of the two-reactor plant has been shut down since May 1989. Unit 1 was brought into service in October, but was shut down for three weeks in December, BG&E spokesman Arthur J. Slusark said.
This is the seventh fuel adjustment increase BG&E has requested since mid-1989. The previous increases have added $6.59 a month to the residential bill for a customer who uses 900 kilowatts a month.
