Power re­serve de­cline slows

Sum­mer short­ages are pos­si­ble, but thin­ning of mar­gins not as stark in the new­est forecast.

The threat of long-term power short­ages on the state’s pri­mary elec­tric­ity grid con­tin­ues for the sum­mer’s peak de­mand, ac­cord­ing to the lat­est pro­jec­tions, as re­serve mar­gins con­tinue to de­cline — but at a slower pace than had been pro­jected six months ago.

The Elec­tric Re­li­a­bil­ity Coun­cil of Texas, the op­er­a­tor of the grid that serves three­fourths of the state, in­clud­ing Cen­tral Texas, up­dated its sup­ply-and-de­mand forecast Mon­day.

“The pro­jected re­serve mar­gin for sum­mer 2013 has dropped slightly since May, but we are see­ing health­ier re­serve mar­gins in fu­ture years,” said ERCOT CEO Trip Doggett. “Although peak de­mand is ex­pected to grow less quickly than pre­vi­ous eco­nomic pre­dic­tions in­di­cated, we should con­tinue to en­cour­age new gen­er­a­tion and de­velop more de­mand re­sponse op­tions to re­duce our elec­tric use dur­ing pe­ri­ods of high­est use — the hottest hours of the hottest days of sum­mer.”

Mon­day’s forecast projects that ERCOT will have 74,633 megawatts of power to serve an­tic­i­pated peak elec­tric use, or “load,” of 65,952 megawatts next sum­mer. A megawatt is enough power to serve about 200 Texas homes dur­ing the high­est-de­mand pe­riod, which typ­i­cally oc­curs be­tween 3 and 7 p.m. dur­ing the hottest days of sum­mer.

The up­dated forecast will be in­ter­preted by var­i­ous fac­tions
