Cooling-demand controls look good

Field attempts to examine and quantify reductions in system peak load by controlling residential air conditioning got under way last summer with tests at Georgia Power, Arkansas P and L, and Detroit Edison. Three other projects are now under way. On June 1, Mississippi P and L began to control air-conditioning and water-heating loads of 200 residential customers between 2 and 6 P.M. each weekday, using a ripple control system. The air-conditioning compressor will be shut off for 15 minutes of every hour when temperatures are 90/sup 0/F or higher. The system will also be used to control demand at a major shopping center (50 stores) and about six selected industrial customers; their production will not be affected. The Cobb County (Ga) Rural Electric Membership Corp has about 4,200 demand controllers installed on its system to control air-conditioning loads on a voluntary basis, with an additional 10,000 installed in time for the 1977 summer peak. The co-op expects to be able to shave 5 MW from its peak load (thus saving $250,000) this summer and a total of 10 MW ($500,000) next summer. The radio-controlled equipment will shut off the compressors for 7 of every 28 minutes during peak loads. The Southwest Public Power District, in Nebraska, has installed about 300 ripple-control switches, primarily on irrigation pumps; about 40 of them, however, are installed on air conditioners and water heaters, on a voluntary basis.
