California’s Public Interest Energy (PIER) Program has received a final report that provides an analysis of the impacts, costs and timelines for distributed generation interconnection in California.
The new report, “Improving Interconnections in California”, covers four areas.
As to the project goals listed above, the authors found the following:
The process of interconnection in California has been improved by 83% over a baseline level. The time reduction objective of 20 percent is exceeded every year under the Revised Rule 21 by a large margin since 2000.
Nine DG technology packages – microturbines, fuel cells and induction generators – have been certified to use simplified interconnection procedures.
The weighted average of the cost savings of the DG projects analyzed shows an end-user cost savings of 74% to reach a point of interconnection. This exceeds the target of 30%. The costs associated with delays in interconnection approval and installation have been reduced by more than 20% for projects of all sizes.
