Customized Projects
Do you have ideas for other technologies that will save energy?
You can design your own energy efficiency project. Custom rebates are based on projected energy savings for new construction or retrofit projects. Projects are evaluated on a case-by-case basis and must be pre-approved by Hawaii Energy before equipment purchase. Please contact us to discuss your project.

Limited-Time Offer! Doubled Rebate for Custom Energy Savings
New custom projects completed by June 30, 2025 are eligible to receive 2x the energy savings rebate! Contact us or your Energy Advisor today to apply for pre-approval prior to beginning your project.
| Custom Project Equipment Life | Incentive Rates |
≤< 5 years | WAS $0.08 per kWh saved + $125 per kW saved between 5 to 9pm NOW $0.16 per kWh saved + $125 per kW saved between 5 to 9pm |
| > 5 years | WAS $0.12 per kWh saved + $125 per kW saved between 5 to 9pm NOW $0.24 per kWh saved + $125 per kW saved between 5 to 9pm |
Limited Time Offer, Custom Projects Must Follow The Rules and Requirements Below:
- Projects that have received pre-approval prior to January 15, 2025 are not eligible.
- This limited-time offer is not guaranteed for projects that are delayed beyond the June 30, 2025 deadline.
- Equipment must be installed and operational by the June 30, 2025 deadline.
- Final documentation and requirements such as invoice(s) and post-installation data, if required, must be submitted to Hawaii Energy by June 30, 2025.
- New construction is not eligible.
- Written pre-approval from Hawaii Energy is required to qualify, including:
- A signed Commercial Incentive Application is required for pre-approval.
- A scope of work is required for pre-approval.
- Total rebate is capped at 50% of project costs.
- This bonus cannot be combined with another bonus offer. Contact us or your Energy Advisor with your project proposal to apply for pre-approval.
Custom Program Rules
- In order to ensure the best chances of qualifying for an incentive, Hawaii Energy requires that you contact our program for preliminary approval prior to the start of any work. Otherwise, the project is at significant risk of being disqualified. Projects are handled on a case-by-case basis and may require documentation before and after implementation (e.g. pre- and post-data, pre-inspection, etc.).
- Incentives can be up to 50% of project costs (based on the project’s first year savings).
- The simple payback must be greater than one year.
- Incentives are based on projected energy and peak demand savings for both new construction and retrofit projects.
- Rules are subject to change without notice at Hawaii Energy’s discretion. Please visit this page for the most up-to-date requirements.
Custom Project Requirements
Project requirements vary on a case-by-case basis. Please consult with an Energy Advisor and apply for pre-approval before purchasing any equipment. Typical project requirements may include but not limited to the following:
Pre-installation and post-installation metering*
- 15-minute interval data. May require higher frequency of data logging depending on equipment type.
- Data must be time-stamped (mm/dd/yy hh:mm)
- Power measurements are required (kW)
- Depending on the system, additional data points may be required such as tons of cooling, flow, temperature etc.
- At least four weeks of data on existing equipment and four weeks of data on new equipment
- Submission of raw data
Data analysis and engineering calculations
- Provide energy savings and peak demand savings values based on metered data or
engineering calculations - Provide a document showing the engineering calculations and stating any assumptions and key information about the project
- Standard engineering principles must be applied and all references cited
- Proposed base and enhanced calculations must be performed by a qualified person or firm. In some cases, a professional engineer may be required to provide verification of the analysis
Note: For new construction, “pre” or “base case” is typically interpreted as commonly available new equipment at a lower efficiency option or code requirements, whichever is higher.
*Energy savings analysis from metered data will be normalized to weather, flow, or other data to extrapolate energy savings over time.
