Electric Power Supply and Demand Results for Summer 2012
October 02, 2012
Chubu Electric Power Co.,Inc.
Now that the period of Government-requested nationwide energy conservation is over, Chubu Electric Power would like to announce that it has compiled electric power supply and demand results for this summer.
Amid fears of electricity shortages in the wake of the nationwide shutdown of nuclear power plants, we were able to maintain a stable supply this summer because of the continued energy-conservation efforts of customers in our region since last summer.
We very much appreciate the extensive cooperation that we have received from our customers and would like to express our sincere thanks to them.
1 Electric power supply and demand results for summer 2012
This summer an energy conservation target of at least 5%* of summer 2010 peak electricity usage (the baseline) was set in our region. Thanks to cooperation from many of our customers, and because no heat wave similar to that of 2010 occurred, the peak load was 24,780 MW (July 27). This was 1,700 MW below the estimated value of 26,480 MW (calculated from the one-time peak load for the FY2010 heat wave by factoring in energy conservation measures).
*Target set by the Government for customers in our region. Changed from 5% to 4% on July 10 after the resumption of operations at Kansai Electric Power Co. Oi Nuclear Power Station, then replaced by a "General request for energy conservation without numerical targets" on July 26.
(2)Energy conservation effects
In addition to cooperation from industrial customers on planned adjustment contracts since last year, the energy conservation efforts of numerous general domestic and corporate customers resulted in an estimated energy-saving of 1,550 MW (including 250 MW through planned adjustment contracts) that, at 6.1% of the FY2010 baseline, exceeded the target for energy conservation.
2 Supply capacity
We put in place the capacity to provide a stable supply by effectively implementing pre-planned supply measures that included deferring the regular inspection of thermal power units and changing maintenance schedules. At the same time, energy conservation efforts by our customers together with this summer's weather conditions meant that demand for electricity remained lower than expected.
After requests from Kansai Electric Power and Kyushu Electric Power, which were facing a severe imbalance in electricity supply and demand, provided that we were able to avoid disrupting supply in our region we sold as much surplus power as possible to these utilities. Thus, we were able to contribute to stability of supply in western Japan.
Once again, we would like to thank our customers for their wholehearted cooperation with energy conservation measures this summer.
