<br /> BACKGROUND:
<br /> With approval from the Board of Public Utilities and the City Council,the Public Utilities Department(RPU)is
<br /> constructing RERC Units 3 and 4,which will provide 96 megawatts of internal generation. All extemal power
<br /> to serve Riverside customers comes from the state transmission grid through a single point of
<br /> interconnection, via the Vista Substation. The capacity at Vista is 560 megawatts (MW). Power is also
<br /> provided by the 96 MW RERC Units 1 and 2 and the 40 MW Springs Generating Station. Both facilities are
<br /> peaking units and are licensed to run only a limited number of hours per year. Three times this past summer,
<br /> RPU surpassed the import capacity at Vista Substation and relied on intemal generating units in order meet
<br /> customer demand. Those three days were in the "top ten" peak days for RPU, and all of these days
<br /> surpassed Vista's capacity, Even during these recessionary times, power demand is still at very high levels
