Connect Your Home to Utilities in Honolulu

Honolulu is more than just beautiful beaches and golden sunsets, it’s a vibrant city with a rich cultural tapestry, buzzing urban life, and lush island nature all rolled into one. As the capital of Hawaii and the largest city on Oahu, it blends bustling neighborhoods with laid‑back vibes. Whether you’re in Waikīkī, Manoa, or the slopes of Kalihi, it’s a place where island tradition meets modern living. Now, let’s look at the essentials to keep your home running smoothly, starting with utilities.

Electricity

Hawaiian Electric Company (HECO) is Honolulu’s main electricity provider, serving about 95% of the population across Oahu. They’re a longstanding pillar in Honolulu, operating since 1891, and have ambitious goals to reach 100% renewable energy by 2045.

HECO partner, Hawaii Energy, administers a wide range of energy efficiency rebates. You can get cash incentives for:

• Heat pump water heaters, solar‑water‑heater tune‑ups
• ENERGY STAR appliances
• LED lighting and ceiling fans
• HVAC tune‑ups

Combined with federal and state credits, these rebates can cover up to ~70% of costs for major upgrades. Plus, programs like GEM$ On-Bill Money Saver offer on-bill financing for solar and energy storage systems, helpful if you’re planning solar installations.

HECO’s sustainability mission is strong: they run the “Bring Your Own Device Plus (BYOD Plus)” storage incentives and have plans for energy storage and rooftop solar expansion. So, it’s an exciting time to save energy and support green infrastructure.

Natural Gas

Hawaii  Gas is Honolulu’s primary provider of gas service, supplying both Synthetic Natural Gas (SNG) and propane to residential customers in O‘ahu’s pipeline-connected areas and beyond. While the city lacks natural gas pipelines in the traditional sense, Hawaii Gas maintains a locally produced SNG plant near Campbell Industrial Park and an extensive 1,000-mile underground pipeline network delivering gas from Kapolei to Hawai‘i Kai. This infrastructure allows many Honolulu homes to access continuous, reliable gas service.

Benefits include:

• Efficiency & cost savings: Gas appliances typically use up to 28% less energy than electric equivalents.
• Clean burning fuel: SNG emits up to 40% less CO₂ than oil or coal when used instead of electric generation.
• Resilience: Unlike electric power, Hawaii Gas service continues during grid outages, making it ideal for gas stoves, water heaters, clothes dryers, and even gas-powered backup generators.

Installation & Rebates

Hawaii Gas supports both new pipeline connections and propane tank setups for homes outside the pipeline system. They help you pair up with licensed plumbers, coordinate permitting, and handle all external installation work.

As part of their “Good Energy Rewards” program, you may receive:

• $500 credit when installing a gas water heater plus two other gas appliances
• $100 credit for adding or replacing a gas range, cooktop, oven, dryer, or water heater.

Additionally, their Utility Customer Appreciation Credit provides a monthly rebate funded by the company’s agreement post-acquisition, something to look forward to.

Water & Wastewater

The Honolulu Board of Water Supply handles water and sewer utilities. Since water is precious in Hawaii, conservation is key. Expect tiered pricing encourages efficient use, so shorter showers and fixing leaks can lead to noticeable savings.

Bonus tip: collect rainwater for gardening (where local codes allow) to reduce your meter usage.

Trash & Recycling

The City and County of Honolulu Refuse Division runs regular curbside trash, recycling, and bulky-item pick-up. If you live in a multi-unit building, property management may coordinate. Recycling is mandatory, paper, cardboard, glass, metal, green waste, and more go into your blue carts. They also offer seasonal bulky-item and appliance collection events. It’s a good idea to compost food scraps, both to reduce landfill waste and to create nutrient-rich soil for a garden!

Best Internet Providers in Honolulu

Honolulu offers impressive options for internet, though availability varies by neighborhood:

• Spectrum: Covers ~90% of Honolulu, offers speeds up to 1 Gbps over it’s cable network, no data caps. Plans start around $30/mo intro pricing.
• Hawaiian Telcom (altaFiber): Covers ~92% of the urban center, fiber service reaches up to 1 Gbps. Known for reliable fiber, but often with annual contracts and router fees.

• Verizon Home Internet: ~99% coverage, speeds up to 300 Mbps over a wireless 5G network.

• Residential solar installations are booming, powered by companies like Island Pacific Energy and Sunetric, both offering financing, power purchase, and installation services.
• State and federal solar incentives (35% state + 30% federal) are available.
• HECO’s storage rebates, energy-efficiency programs, and renewable portfolio goals support a cleaner grid.
