CPUC Releases New Draft Ruling on California Solar Initiative

The California Public Utilities Commission released a 136-page draft ruling this week on the California Solar Initiative that takes many steps forward from the previous version and includes a number of recommendations from the various California solar industry representatives.

The rebate level in this draft increases to $2.50 per watt installed, up from $1.50 in the previous draft. For government and non-profit customers up to 100 kilowatts, the rebate will be $3.25 per watt. Presumably, this is balance out the fact that government and non-profit customers are not eligible to also receive a financial incentive from any current or future Federal tax laws, such as the current 30 percent tax credit. Most notably, the current draft proposes a 5-year performance-based incentive (PBI) of 39 cents per kWh for systems sized 100 kW and up (50 cents per kWh for government and non profit customers). Solar energy industry representatives such as PV Now, CALSEIA, Vote Solar and Americans for Solar Power (ASPv) are preparing to file joint comments before the early-August deadline. The final decision to adopt the ruling is expected on August 24th. Further decisions and adjustments are expected to be made over the coming year. A more complete summary of the 136-page draft decision follows (courtesy of Americans for Solar Power (ASPv)). Retrofit projects 100 kW and greater – declining performance based incentives (PBI) – Starting at 39 cents/kWh over 5 years for commercial projects that can utilize federal tax incentives – 50 cents/kWh for 5 years for non-profit and government projects (must certify not third party financed) – All building integrated PV (BIPv) PBI required – Monthly payments (utility discretion to include payment in bill or separate from bill) – Any project can “opt in” to PBI Retrofit projects less than 100 kW – declining up-front incentive based on “expected performance” – $2.50/watt for commercial projects that can utilize federal tax benefits – $3.25 for non-profit and government projects (must certify not third party financed) – 30 to 100 kW market – 2 to 3 years to transition to PBI in 2010 – New construction projects incentives based on expected performance – Optimal design factors for south, southwest and west orientations (peak or maximum output) – Treat all systems equally that are oriented between 180 to 270 degrees, include location specific criteria, determine optimal latitude tilt that relates to local latitude Incentive Adjustment – Decline based on achieved levels of solar demand- specified MW limit of applications that are conditionally approved – May vary based on utility service territory, some utilities may use their budgets more quickly Funding Levels – Reserve CSI funds for residential customers 1/3 of CSI (33%) (currently represent 1/3 of total system sales) – Commercial and tax exempt customers 20% – Non residential customers 47% Meters – Revenue grade meters for all systems required (less than 1% cost for up to 30 kW and up to .5% for larger systems) – Solar customer pays for all metering costs – Independent Performance Monitoring, Access to Solar Performance Information (customer & program) Program Management/Program administrators – Remain with current SGIP program managers for 2007 – Directed to issue solicitation to design expected performance protocol and estimation tool by November 1, 2006. – Must develop coordinated training plan for estimated performance site inspectors w/plan by January 2007 – Must issue RFP for a state wide application processing and data accumulation Created new “CSI Program Forum” – PUC Energy Division -First Quarter 2007 – Provides for stakeholder participation and development of consensus based solutions Soon to be released Draft Decisions – Incentives for technologies other than PV – Energy Efficiency requirements Phase 2 Issues Identified in Draft ALJ Phase 1 Decision – Statewide Marketing and Outreach efforts – Program Administration for residential retrofit program – Verification of system output – REC ownership and how solar RECs fit into RPS process – TOU tariffs – Program Handbook- recommend Metering and Data Committee of Interested Parties (Provided schedule for workshop, Energy Division Draft, ALJ Ruling, Comments & Reply comments, and ALJ Decision) Periodic Review Process – All aspects can be re-examined – CSI Program review currently scheduled for 2009 or earlier Issues currently envisioned: – Government and non-profit customers- are higher incentives required? – Incentive changes due to change in tax credits – Review capacity factor use in PBI payment based on measurement and evaluation findings – Application of PBI for all systems over 30 kW – Review budget reservation of one-third CSI budget for residential customers – Investigate feed-in tariff approach – Consider adding trackers to the up-front estimated performance incentive Phase 2 Schedule and Scope is Uncertain The full draft ruling (136 pages, .pdf) can be viewed at the following link.
