None of these measures are blockbusters. The biggest energy saver, plug load, would reduce electric use only 3.4 percent by 2030. But together the measures could achieve savings of 15 to 31 percent in electricity use, the report said.
Most would cost 7.5 cents/kWh or less (based on a total resource cost) so would be cheaper than building a new natural-gas-fired power plant.
The 18 measures are:
- High-efficiency residential appliances (refrigerators, clothes washers, and clothes dryers)
- Residential LEDs targeted at current incandescent applications
- Real-time feedback on energy use to promote customers’ conservation behaviors
- Residential smart (learning) thermostats
- Advanced residential air conditioners and heat pumps
- Heat pump water heaters
- Comprehensive residential retrofits
- New construction programs targeting future model and state building codes
- Large reductions in key targeted plug loads (miscellaneous energy loads)
- Advanced commercial lighting design and controls
- Advanced commercial rooftop air-conditioning units
- Smart commercial buildings
- Comprehensive commercial retrofits
- Strategic energy management for large commercial and industrial customers
- Energy performance labels for commercial and industrial equipment
- Smart manufacturing
- Conservation voltage reduction
- Combined heat and power
CHP growth is hampered by a variety of factors, one being that its benefits are not always monetized. For example, CHP can keep the lights on at a hospital or other critical facility during a crisis. And it is in fact often a part of a microgrid. Yet CHP receives no payment for this reliability and resiliency service. Finding a way to pay CHP operators for this service would go a long way in accelerating CHP use.
