KIUC Bill Too High? Going Solar with Sunrun Will Put You in Control

Learn How to Lower Your Kauai Island Utility Cooperative Bill with Solar Panels & a Home Battery

According to recent data, home electricity rates in Hawaii are more than twice as high than in other U.S. states.1 Fortunately, the price of solar continues to fall in the country2, and switching to solar energy, today is one of the best ways to take control of your electric bill — and potentially save thousands of dollars during the next 25 years*3 — while effectively reducing your carbon emissions.

With a home solar battery system from a company like Sunrun, you won’t just gain energy independence and boost your energy savings, you’ll also have reliable backup power during an outage. But before we discuss the benefits of solar, let’s go through who KIUC is, as well as the things they’re doing to tackle extreme weather and protect the communities and the environment of the Hawaiian Islands.

Who Is KIUC and How Many Customers Do They Have?

Kauai Island Utility Cooperative is one of the country’s newest electric cooperatives — and the only electric cooperative in Hawaii. KIUC works as a not-for-profit organization, owned by its members and controlled by an elected board of directors. To date, Kauai Island Utility Cooperative delivers electricity to more than 33,000 homes and businesses on the island of Kawai.4

7 Tips to Save Money on Your KIUC Electric Bill5

  1. Set your thermostat to 78 to 80 degrees when you’re home, and 5 to 10 degrees warmer when you’re out. Or better yet, upgrade to a smart thermostat so it can adjust your cooling patterns automatically depending on if you’re home or not.
  2. Weather-strip your doors and windows, so the warm air outside stays out, and the cool air inside stays in. If you think your home has air leaks, a DIY home energy checkup can help you pinpoint some of the easier areas to address before reaching out to a professional.Check out this simple guide for a DIY home energy audit.
  3. Use ceiling or floor fans instead of your air conditioner whenever possible. Fans consume around 90% less energy than a central AC system.
  4. Replace your regular light bulbs with energy-efficient LEDs. LEDs give you the same amount of light as regular bulbs, but use up to 75% percent less energy and last up to 10 times longer.
  5. Wash your clothes in cold vs. hot water. Switching from a warm to cold cycle for just two laundry loads each week could save you approximately $70 per year.
  6. When drying clothes, always clean your dryer’s lint filter after each use and don’t over-dry your clothes. This could save you a considerable amount of money each year and help you maintain your clothes in better shape for a longer time, too.
  7. Consider upgrading your old devices and appliances to energy-efficient units and get up to 40% higher energy efficiency. Always look for the ENERGY STAR® label to ensure you’ll save money with your new electronics.

How Does KIUC Calculate Your Solar Bill?

Using a bi-directional meter, Kauai Island Utility Cooperative will measure the difference between the kilowatt-hours your system produces and the electricity your home consumes from the grid. This difference is called Net Energy Metering or NEM, and it’s used to calculate your solar bill.

And when your panels create more energy than you need, the excess will be exported back to the electric grid, and KIUC will give you a credit on your next bill.11
