Electric & Gas Energy Efficiency Programs and SavingsList All

In 2019, according to EIA, Hawai’i Electric reported 106,362 MWh of net electric savings at the meter, which represents 1.62% of its retail sales. In 2019, Hawai’i Electric spent $$27,447,000 on electric energy efficiency programs, which represents 1.54% of its electric retail revenue. 

In 2019, Hawai’i Gas did not run any natural gas programs in Honolulu, due to the low amount of natural gas Hawai’i consumes. These spending and savings figures cover the utility’s entire service jurisdiction, not just Honolulu. 

Hawai’i Electric offers electric efficiency incentives and technical assistance to residential and business customers. 

Hawai‘i Energy is working with specific agencies within the State of Hawai‘i on targeted, building and equipment-level efficiency. These include the Department of Accounting and General Services and the Hawai‘i Public Utilities Commission. These agencies and Hawai‘i Energy have an agreement through Hawai‘i Energy’s Strategic Energy Management (SEM) program, which offers in-depth energy use analysis, savings opportunities, support overcoming internal barriers, support for financing and green revolving funds, and more, for a time frame ranging twelve to thirty-six months. Another strong SEM participant is the County of Hawai‘i. Their Department of Water Supply and Hawai‘i Energy teamed up to purchase and install hundreds of leak detection loggers as a means of identifying and locating leaks much faster than without the loggers. Significant energy savings have been measured and quantified, with of course the added benefit of considerable water savings as well. Hawai’i Energy partnered with the State Department of Business, Economic Development & Tourism (DBEDT) to advocate for County-level adoption of the 2015 International Energy Conservation Code (IECC), offering trainings together across each of four counties to the construction, architecture and engineering industry. 

In partnership with the City and County of Honolulu, the utility implemented its Energy Smart 4 Homes program with over 1,000 city-owned units. Through the program, professionals installed energy-efficient showerheads and faucets, along with ENERGY STAR® LED bulbs at no cost that will allow residents to save up to $160 a year. The utility is also heavily integrated with the City & County of Honolulu’s Office of Climate Change, Sustainability, and Resiliency. The utility regularly participates in Honolulu’s various Climate Action and Resiliency stakeholder meetings, ensuring energy efficiency is cornerstone in the conversations of reduced fossil fuel usage and equity in access to clean energy.

Low-Income & Multifamily EE Programs List All

Low-Income Programs 

Hawai’i Energy offers the Energy Smart 4 Homes (ES4H) program, which residential single-family and multi-family customers with direct access to turnkey energy efficiency solutions, such as high-efficiency lighting and water measures and energy management devices. The properties serviced through the ES4H program were provided at no-cost to residents and ownership management, including all labor and materials. Although the access to large multi-family complexes decreased on O‘ahu, the program deployed more resources in Maui and Hawai‘i Counties and increased its service to single-family residences at targeted communities. The program worked with a channel partner to retrofit properties in both the public and private sectors. 

Hawai’i Energy also offers the Bulk Appliance Purchase Program. Residents of geographically isolated areas, such as the island of Lāna‘i face multiple barriers in the supply chain including accessibility to retailers, transportation & field services, and disposal & recycle options. Hawai‘i Energy collaborated with the island’s largest landowner, Pūlama Lāna‘i, to provide energy efficiency measures through the Community-Based Energy Efficiency framework (refer to the Transformational Programs section for further details). At Iwiole Hale, a low-income and affordable multifamily property, over 100 inefficient refrigerators were replaced with new, discounted 18 cubic-foot ENERGY STAR® models.  The effective delivery and installation of the new units was attributed to the quick responsiveness from supply chain allies and the clear communication between Hawai‘i Energy, Pūlama Lāna‘i management, and the tenants. 

Data on Hawai’i Energy customers served, savings, and spending for low-income customers was not available in 2019. 

Multifamily Programs 

Hawai’i Energy offers the Energy Smart 4 Homes (ES4H) program, which provides multifamily customers direct access to no-cost energy efficiency solutions, such as high-efficiency lighting and water measures and energy management devices. In addition to work in individual units, the program provides common area lighting retrofits at enhanced incentive levels. Savings, spending, and participation data for 2019 was not available.
