In 2011, the Hawaiian Clean Energy Initiative established the most aggressive clean energy goals in the US: 70% clean energy by 2030. Of this, 30% is from improved efficiency measures, and 40% is from locally generated renewable energy resources. In support of this, the Hawaiian Electric Company recently contracted with DRRC to develop a plan (roadmap) for using demand response to support the integration of renewable resources.Three principles shaped the development of that plan:
- Technology should support a wide range of customer needs by offering a continuum of control and system response endpoints.
- Technology choices should reflect the best options available that also provide the capability to adapt to future needs, designed with functional separations between system control, communication, and end-use control technologies.
- Time-differentiated efficiency is critical. Although widespread deployment of smart meters has not proven cost effective for Hawaii, there is a need to manage intra-hour variability introduced by renewable resources.
A follow-on effort to introduce fast demand response in the hospitality sector has begun. The Hospitality Study Project will use OpenADR with advanced features such as real-time feedback and the opportunity for ancillary services essential to assisting in the integration of renewable resources and maintaining power quality, reliability, and security. Separately, HECO is working with EPRI and a thermal energy storage vendor to examine residential electric resistance water heater end use controls to mitigate variability arising from the integration of wind energy resources.
