Community Based Renewable Energy

What is Community Based Renewable Energy?

In 2015, Act 100 of the Hawaii State Legislature directed the Hawaii Public Utilities Commission (PUC) to establish a “community-based renewable energy” tariff (Section 269-27.4, Hawaii Revised Statutes). The details of the tariffs and programs have been (and are being) developed under PUC Docket No. 2015-0389.

A tariff is a published volume of rate schedules and general terms and conditions under which a product or service will be supplied.

The stated intent of the program is “to make the benefits of renewable energy generation more accessible to a greater number” of Hawaii residents and businesses who would otherwise be unable to directly participate in renewable energy generation for reasons such as lack of upfront capital for their own renewable energy system; building or home location, which may not receive enough sunlight or may be located on a saturated circuit; building type or roof design which may not be able to physically support the solar panels; proximity or other limited access to the utility grid; and/or property ownership status (e.g., renters, lessees).

Community-based renewable energy (CBRE) is also commonly referred to as “community solar” and is referred to by Hawaiian Electric as “Shared Solar.”  In a CBRE program:

A Subscriber Organization is a company, organization, or group of people who owns, develops, or operates a CBRE project in an electric utility’s service territory.

A Subscriber is a customer (in the service territory of the same electric utility) who agrees to pay a Subscriber Organization for a portion of the output from the Subscriber Organization’s renewable energy project. These credits are applied to the Subscriber’s electric utility account to offset a portion of the Subscriber’s electricity bill.

It is important to note that Subscribers purchase the renewable energy credits from a Subscriber Organization and the electric utility applies those credits to the Subscriber’s electric bill.

Current Status of Hawaii’s CBRE Program

Phase 1 CBRE

UPDATE: CBRE Phase 2 Request for Proposals (RFP) for LMI Subscribers on Oahu, Maui, and Hawaii Island is Open

Additional information is available on Hawaiian Electric’s Tranche 1 and CBRE LMI RFP webpages

RFP for Molokai and Lanai Subscribers

CBRE Lanai RFP Documents are Available on Hawaiian Electric’s CBRE Lanai RFP Documents Webpage

CBRE Molokai Documents are Available on Hawaiian Electric’s CBRE Molokai RFP Documents Webpage

  • Kauai Island Utility Cooperative (KIUC) is not currently reviewing CBRE projects.

After the RFP is Approved – CBRE Phase 2 

1.  Subscriber Organizations will bid on the RFP or fill out an application depending on the CBRE project size. Project sizes are summarized in the table below, based on the current RFP.

“LMI” means “low and moderate income.”, “PPA” means “power purchase agreement


Large Projects

Mid Tier Projects

Small Projects


> 5 MW
(LMI and Tranche 1)

250 kW – 5 MW
(LMI and Tranche 1)

< 250 kW

Maui, Lanai, and Hawaii Island

> 2.5 MW
(LMI Applicants Only)

250 kW – 2.5 MW
(LMI and Tranche 1)

< 250 kW



250 kW – 2.5 MW

< 250 kW

  • Small projects complete an application and submit it to Hawaiian Electric.
  • Mid-Tier projects require procurement through a formal RFP competitive bid process.
  • Large Projects require a separate PPA approval from the PUC.

2.  The electric utility will contract with Subscriber Organizations for the electrical output from the project(s).

3.  Each project will undergo planning, permitting, construction, and interconnection to the electric utility.

4.  Subscriber Organizations will announce and advertise shares for lease or purchase to potential Subscribers.

When the CBRE Project is Available for Customer Subscription

5. Subscribers will select from the eligible CBRE projects in their service territory.

  • Subscribers will enter a “Subscriber Agreement” with the Subscriber Organizations for an interest in the CBRE project(s) they choose.

6.  Each Subscriber Organization will sell the monthly kWh generated by the CBRE project to the electric utility. 

7.  The Electric Utility will convert the purchased kWh to a dollar amount. 

8.  The Subscriber will receive a credit from the utility based on their share of the CBRE project and the amount will be deducted from the Subscriber’s monthly utility bill.

    • The bill credit is based on a preset credit rate, the amount of electricity generated, and the size of the customer’s subscription with the Subscriber Organization.

How to Become a Subscriber Organization

A Subscriber Organization can be any organization such as a neighborhood, club, homeowners’ association, church, labor union, charitable organization, environmental organization, or a company that develops renewable energy facilities. The utility can act as a subscriber organization under certain circumstances.  

Potential Subscriber Organizations for Hawaiian Electric’s service area should register at:

How to Become a Subscriber

Only customers of a Hawaii electric utility, with an active account and account number, can sign up to be a Subscriber.  Eligible utility customers may include homeowners, renters, business owners, or lessees.

To participate in CBRE, Subscribers must agree to share their electric account data with Hawaiian Electric, the program enrollment software provider, and the Subscriber Organization.

Hawaiian Electric customers should Visit to enroll.

If a Subscriber moves to another location on the same island, their subscription can move with them.  If a Subscriber moves off the island, the Subscriber can sell the subscription back to the Subscriber Organization.
