Energy Efficiency Potential Study, State of Hawaii

  • 2020 by Applied Energy Group (AEG)
    In 2018 through 2020, the Hawaii Public Utilities Commission conducted a second independent evaluation of energy efficiency (EE) market potential in the State of Hawaii from 2018–2030 (first evaluation was conducted in 2013). This study assesses the potential of future energy savings that can be achieved by contributing entities and applicable toward the goals outlined in the state’s Energy Efficiency Portfolio Standard (EEPS). This second evaluation study provided hourly stacked impacts of potential from EE, electric vehicles, demand response/grid services, and a time-of-use rate over the next 20 years. The EEPS target appears to be attainable under the current programming scenario and a high amount of additional cost-effective savings (over 1,000 GWh) are available, delivering substantial savings to electric utility customers through the state.
  • 2013 by EnerNOC Utility Solutions
    In 2013, the Hawaii Public Utilities Commission conducted an independent evaluation of energy efficiency (EE) market potential in the State of Hawaii from 2013–2030. This study identifies the un-tapped savings potential that can be achieved by contributing entities and applicable toward the goals outlined in the state’s Energy Efficiency Portfolio Standard (EEPS). The study estimates that cost-effective cumulative energy efficiency potential in 2030 is 6,210 GWh, or about 144% of current EEPS goals. This indicates that the while the EEPS goals are aggressive, it is likely they can be met cost-effectively, delivering substantial savings to electric utility customers throughout the state.

Reliability

Reliability Standards Working Group (RSWG) Facilitator’s Report
March 13, 2013 – In 2010 the Hawaii Public Utilities Commission indicated its intent to establish a Reliability Standards Working Group (RSWG): that group began working together in July 2011 under Docket 2008-0273.  Since that time the RSWG has been meeting and working diligently to produce policy and technical recommendations that will facilitate the increased use of renewable energy in the islands without compromising the grid reliability.

Renewable Energy

Assessment of the State of Hawaii’s Ability to Achieve 2010 Renewable Portfolio Standards
Pursuant to Hawaii Revised Statutes (HRS) § 269-95, the University of Hawaii, Hawaii Natural Energy Institute (HNEI) assessed the capability and likelihood of the electric utility companies in the state – Hawaiian Electric Company, Inc. (HECO), Hawaii Electric Light Company, Inc. (HELCO), Maui Electric Company, Ltd. (MECO) (collectively, HECO Companies or HECO Utilities), and Kauai Island Utility Cooperative (KIUC) – to achieve the 2010 Renewable Portfolio Standard (RPS) in a cost-effective manner.

Evaluation of Hawaii’s Renewable Energy Policy and Procurement
This report provides foundational analysis on the estimated economic costs and benefits of Hawaii’s various renewable energy procurement programs, which include net energy metering, feed-in tariff, and energy procured under the existing competitive bidding framework for large-scale energy generation.  The National Association of Regulatory Utility Commissioners contracted with Energy + Environmental Economics on the Public Utilities Commission’s behalf for this study and report.
