July 30, 2003[SolarAccess.com]REPP has begun an initiative to analyze the experience of states with Renewable Portfolio Standard (RPS) implementation. To the extent that the data is available, REPP will track and report the cost of renewables to determine whether costs have declined under RPS policies. REPP will also look at the evaluations conducted by states. As a first case, REPP analyzed a recent analysis of the Arizona RPS, which had two significant results. First, it found that the installed cost of PV systems declined significantly. The report also conducted a cost-benefit analysis of the RPS, which found that costs were significantly greater than reported benefits. REPP found a number of questionable assumptions in the cost-benefit analysis and re-ran it. The REPP analysis then showed costs and benefits to be equal.
