HELCO tiered rate structure in effect Friday (Jan 14)


January 12, 2011

Residential customers at Hawaii Electric Light Company (HELCO) and Maui Electric Company (MECO) will be rewarded for energy conservation through a new tiered rate structure approved recently by the Hawaii Public Utilities Commission (PUC.)

The new rate structure will be effective for MECO today, January 12, 2011. It will become effective for HELCO on Friday, January 14.

Designed to encourage energy conservation, tiered rates will reward customers with lower electric rates for lower kilowatt-hour (kWh) usage. Customers who use more energy will pay higher rates for the higher increments of energy used.

“This tiered rate design offers our customers an incentive to use energy efficiently. The less you use, the more you save,” said Jay Ignacio, HELCO president.

“We firmly believe that energy conservation plays a critical role in helping our state reach its goal of energy security and less dependence on oil,” said Ed Reinhardt, MECO President.

The PUC has also approved the concept of tiered rates for Hawaiian Electric Company, but must still issue an order to implement them for electric customers on Oahu.

The tiered rate structure consists of three tiers for electric rates. The amount of electricity a customer uses each month determines how many of the tiers apply. Customers with lower monthly electricity usage will pay lower rates per kWh than those who use more electricity. The majority of customer bills fall into the first and second rate tiers.

The following table shows the new rate tiers, along with typical bills for residential customers on each island:

The rates shown above cover portions of the cost of providing electric service, such as the operation of power plants and maintenance of the electric system. In addition, the total customer bill amounts include the costs of fuel used to generate electricity, power purchased from independent power producers, and surcharges such as a PUC-directed surcharge to fund energy efficiency programs in Hawaii. The Hawaiian Electric utilities do not make a profit on fuel.

The PUC also approved the utilities’ request to allow the total amount of electricity used by qualifying low-income customers to be billed only at the lowest rate tier. This exception will be available to customers who provide a copy of their qualification letter for the federally-funded Low Income Home Energy Assistance Program (LIHEAP).

The PUC authorized development of the innovative rate structure as part of final decisions on HELCO’s 2006 rate case and MECO’s 2007 rate case. Customers can find tips on saving energy in their homes at and

Interim decision for HELCO 2010 rate request
The estimated typical bill impacts for Hawaii Island also reflect the impact of the PUC’s interim decision on HELCO’s 2010 rate request, issued on January 7. In its interim decision, the PUC approved a 1.74% increase, or $6 million. The increase will help pay for system upgrade projects including an efficient steam generating unit at Keahole placed in service in 2009 and two major completed West Hawaii transmission line upgrades, as well as increasing operations and maintenance costs for the island’s electrical system.

The increase reflects a settlement agreement with the State Division of Consumer Advocacy. HELCO originally filed its request in December 2009, requesting an overall increase of 6% or $20.9 million.

Time-of-Use rates
In addition, the PUC approved HELCO and MECO requests to implement voluntary time-of-use rates for residential customers. These rates encourage customers to shift their energy use to off-peak periods when generation reserves are greater. Customers who choose to participate will be offered lower electric rates during off-peak periods and higher rates during peak periods.
