Is variable pricing the way out of Hawaii's solar wars?

By Herman K. Trabish, Utility DIVE | August 27, 2015 (abbreviated)

There is a simple way to resolve the solar war in Hawaii and all the stakeholders in the struggle have called for it in one way or another.

The fight is over what solar owners will be paid for the electricity their systems send to the grid. Most agree today’s net energy metering (NEM), which remunerates at the retail electricity rate, no longer works with solar on 12% of the state’s roofs, penetration increasing rapidly, and residents paying the nation's highest electric rates.

The solar wars began when advocates clamored for the state's electric utilities to increase the speed of the transition to distributed solar and the utilities pushed back, arguing for a change in the NEM policy.

“Pricing is key. If you don’t get real about variable pricing and allow prices to vary throughout the day in a flexible way, associated with the true value of the electricity, you get a lot of inefficiency,” explained report coauthor and UHERO Associate Professor of Economics Michael J. Roberts.

An extreme example of the waste from current pricing is what is happening on Maui, Roberts said. The island’s wind generation often exceeds the system’s ability to use it, even with Hawaii’s aging and inflexible thermal plants cycled down as low as possible. The turbines are therefore turned away from the wind, wasting free electricity, while Maui residents continue to pay over $0.40 per kWh for their electricity and some four times the national average, according to Roberts.

Solar is approaching a level, the paper warns, where similar curtailment of residential system owners could be an issue.

“On Maui, the marginal cost for the wind-generated electricity is nearly zero but the price signal doesn’t drop,” explained UHERO Associate Professor of Urban and Regional Planning and paper co-author Makena

Coffman. “That is the inefficiency. If the price dropped, that would be a signal to customers and they would respond over time by shifting the load.”

“It would be better to use the electricity from the wind when it is blowing and there must be people who would use it,” Roberts said. “You could make that happen naturally by letting prices vary.”

One is for any type of customer. It would provide “hourly prices that reflect the continuous variation in supply and demand of electricity.” It would condition customers to price signals. It would also “open a door to innovative ideas for storing electricity or otherwise shifting loads over time.”
