Hawaiian Electric Companies propose new time-of-use rates to help public schools

News Release from HECO November 9, 2015

HONOLULU, November 9, 2015 - The Hawaiian Electric Companies have proposed to the Hawaii Public Utilities Commission new, lower day-time electric rates for the Hawaii Department of Education that could help public schools manage their electricity costs as they add more air conditioning and cooling equipment, while also using renewable energy that is available during day-time hours.

“At the Hawaiian Electric Companies, we know the challenges in providing a comfortable learning environment for our students and teachers,” said Jim Alberts, Hawaiian Electric senior vice president for customer service. “There’s been a big push for air conditioning and fans in our public schools so we wanted to find a way to assist in controlling their energy costs as they add this equipment.

“Our goal in proposing these rates is to give the Department of Education the opportunity to expand air conditioning in classrooms across the state with a tool to manage the increase in electricity use that could really hit a school’s utility budget,” he said.

“These schools are supported by our tax dollars,” said Alberts, “Giving schools greater control over their electric bills will allow more money to pay for education and other priorities.”

Hawaiian Electric estimates that the Department of Education would have saved about 9 percent on electric bills for the twelve months ended June 2015 had the proposed rates been in effect. These savings could help offset the increase in costs as more air-conditioning and cooling equipment is added.

“The department has been working on a number of ways to effectively cool schools,” said Superintendent Kathryn Matayoshi. “The time-of-use rate proposed by Hawaiian Electric would enable us to move forward on air conditioning projects while managing energy costs as well as foster responsible energy usage.”

Each of the 240 public schools in the Hawaiian Electric Companies’ service territories (Hawaii Island, Maui, Molokai, Lanai and Oahu) will have the option to take advantage of the new rates. Actual savings will depend on how much each school is able to change its use to fit the time-of-use rate periods. Participating schools would pay:

• The lowest rate – about 25 percent less than the recent average effective energy charge --from 8 a.m. to 4 p.m. (super off-peak hours).
• A rate that is the same as the existing energy charge rate from midnight to 8 a.m. (off-peak hours).
• A rate that is higher -- above the existing energy charge rate -- from 4 p.m. to midnight (on-peak hours).

Proposed rates also support renewable energy

These rates are also designed to encourage more electricity use during the hours of the day when renewable energy – particularly solar – is adding more low cost electricity to the grid. In addition, by designing time-of-use rates to better match demand with energy supply, the utilities may also reduce the need for additional system resources, including utility generation, during evening peak hours.

The new rates provide educational as well as operational opportunities for students and teachers as well as administrators to see each participating school’s energy use. With the additional grid intelligence from the Hawaiian Electric Companies Smart Power for Schools’ program, electricity use trends with the proposed DOE time-of-use rates can be monitored, managed and evaluated by both the DOE and Hawaiian Electric Companies to refine the rate schedules in the future.

The proposed new rates are called “Schedule DOE-J, Commercial Time-of-Use Service” and “DOE-P, Large Power Time-of-Use Service.” Most schools would fall under the DOE-J rate.

Hawaiian Electric is asking the PUC to allow these rates to go into effect by January 5, 2016 and stay in effect for ten years, through four to five of the Department of Education’s two-year budget cycles to ensure proper evaluation of the stated objectives.

Other time-of-use rate programs to come

The Hawaiian Electric Companies are also developing time-of-use rate proposals that other customers will be able to take advantage of to help manage their energy costs and support renewable energy. Those proposals will be submitted to the PUC this month.
