There were fewer and shorter duration power disruptions and more efficient power generation resulting in higher efficiencies, which held the rates down, he said.
Malae said Georgetown Consulting Group, the Commonwealth Public Utilities Commission’s rate consultant, has noted these “improvements.”
These were among the reasons cited by CPUC when it disapproved CUC’s base rate increase request, he added.
CUC is still waiting for the commission’s final order.
In 2009, CUC had a total of 274,775 megawatt-hour production compared to 278,270 MWh in 2010.
The sale in 2010 reached 215,378 MWh comprising 69,958 MWh from residential customers; 40,265 MWh, government; 105,155 MWh, commercial.
The total production was 278,270 MWh in the same period.
In 2009, the sale was 193,661 MWh: 62,830, residential; 34,610, government; and 96,221, commercial. The total production was 174,775.
Malae said there was a 7 percent increase in sales which represented a 7 percent reduction in “inefficiencies.” This was equivalent to a $420,000 monthly reduction in fuel cost last year, he added.
CUC, he said, is expecting additional efficiency improvements for 2011 due to power factor improvements, turbo charges and installation of new radiators.
Malae said the federal American Recovery and Reinvestment Act financed 95 percent of the improvements.
