OPINION MODIFYING DECISION 06-08-028 REGARDING METERING ACCURACY AND MONITORING REQUIREMENTS

Summary

We modify our decision implementing the California Solar Initiative (CSI), Decision (D.) 06-08-028, to allow solar generation systems that receive incentive payments under the Expected Performance Based Buydown (EPBB) to install meters that are accurate within +/- 5%. We also modify D.06-08-028 to require all systems, irrespective of system size, that participate in the Performance Based Incentive (PBI) program to install meters that are accurate to within +/- 2% of actual system output and eliminate the cost cap. The Metering Subcommittee and Program Administrators are directed to conform the CSI Handbook to these changes.
