Demand Response Benefits
Demand Response (DR) is a partnership: the utility rewards customers who are willing to temporarily reduce electricity use in response to a request from the utility.
Demand Response is Used
- During periods of peak energy use;
- During grid emergencies or to prevent a grid emergency;
- To reduce Hawaii's dependence on imported fossil fuels;
- To assist in accepting more renewable energy onto the grid and into our homes and businesses;
- To keep the grid stable, reliable, and running efficiently.
Demand Response Strategy
Hawaiian Electric's DR strategy is to develop a portfolio of residential and commercial and industrial customer loads which will enable the reliable and economic operation of the modern grid. Our DR strategy will be implemented incrementally, over time, through a combination of shorter-term initiatives including pilot programs, participation in research, development and demonstration projects, and market studies.
Customer Benefits
The newest program in our portfolio, Fast DR is a way to quickly reduce customer's electricity demand for brief periods when power from intermittent renewables such as solar and wind drops off. By reducing customer demand temporarily, Hawaiian Electric is able to reduce the amount of generating units it must continually have available. In short, demand response helps to reduce overall energy costs to all customers and also reduces Hawaii's dependence on imported oil.
Customers participating in the DR programs help to:
- Reduce the system peak, lowering costs for all customers
- Stabilize grid frequency
- Prevent or fix grid emergencies
- Reduce the amount of imported fossil fuel used to generate electricity
- Improve the ability for Hawaiian Electric to use renewable energy
- Keep the grid running reliably and efficiently
Demand Response is one of many Energy Solutions that Hawaiian Electric offers customers to keep electricity costs lower for everyone. Learn which DR program can help tame your electric bills at your home or business:
