Renewable Energy and Energy EfficiencyHonolulu, HawaiiMarch 30, 2009
REGULATOR’S PERSPECTIVE ON
RENEWABLE ENERGY PORTFOLIO STANDARDS
AND
ENERGY EFFICIENCYCarlito P. Caliboso
ChairmanPublic Utilities Commission
State of Hawaii
BackgroundRegulatory Authority
• General supervisory power over public utilities under Chapter 269, HRS. HRS §269-6(a).
• “The public utilities commission may consider the need for increased renewable energy use in exercising its authority under this chapter.” HRS §269-6(b). Act 177 (SLH 2007).
Traditional Regulatory Objectives, Ch. 269 HRS
• Reliable Electricity Service
• Just and Reasonable Rates
• Fair Opportunity to Earn Reasonable Rate of Return
Reasonable Return ($) on Investment for Utility
Reasonable Rates ($) for Customers

• Renewable Portfolio Standards– Standards– Goals
• Broad Policy Tool (Weapon)– Requires % of RE Generation– Communicates Policy to Change
Establishing Energy Policy to Increase RE Generation
• RPS (includes EE), HRS §269-92– 10% Renewable Energy by 2010– 15% Renewable Energy by 2015– 20% Renewable Energy by 2020
• Penalties Established for RPS at $20 per MWh of deficiency. (Order 12/19/2008 Docket 2007-0008)
Establishing Policy to Increase RE Generation: RPS
