The Project

As part of the request for proposal process launched in 2018 by the Hawaiian Electric Company and its subsidiaries, Innergex is pleased to propose the Paeahu Solar Project to the Maui community.

This project combines 15 MW of solar photovoltaic electricity capacity with 60 MWh of battery energy storage on Ulupalakua Ranch land, mauka of Piilani Highway in South Maui. The Project would power approximately 6,900 Maui households with clean, renewable energy.

To power the island of Maui with clean and renewable solar energy, a solar field would be built with arrays of photovoltaic panels arranged in rows supported by fixed-tilt racking foundations. The solar array would charge the battery during the day to provide electricity whenever it is needed most, day or night.

A solar project of this nature also requires the following components: the solar photovoltaic system, a network of electrical collector lines, battery energy storage and inverter units, step-up transformers, a collector substation and transformer, an overhead generation-tie line, internal access roads, and temporary laydown (i.e. staging) areas for construction.

The Paeahu Solar Project must be connected to the grid to supply the community with the needed power. An interconnection route would be built and consist of an overhead transmission line that would extend from the Project switchyard approximately 0.5-mile south to connect into the Maui Electric Company grid at the Auwahi 69 kV substation.

The solar field and associated infrastructure would occupy approximately 150 acres.

About Solar and Battery Storage Systems

The sun is a highly stable and predictable resource, which makes solar technology correspondingly reliable and easy to use. The sun’s energy is converted directly into electricity by a photovoltaic (PV) solar panel, named after the “photovoltaic” phenomenon, where light energy, in the form of photons, can be converted to electricity using certain materials that naturally generate a flow of electrons when exposed to light. As this process requires no fuel, it creates no emissions during operations. As a result, solar energy is one of the cleanest, most reliable forms of energy around.

The effectiveness of a solar energy system depends on a number of factors: the number of hours of sunshine, the season, weather conditions, albedo (the reflecting power of the surrounding surface), etc. Solar panels are always tilted and oriented to capture the maximum amount of light.

Battery storage works by storing the energy produced by solar panels during the day. The higher the battery’s capacity, the more solar energy it can store. The energy in the battery storage can be used whenever it is needed most, day or night.

At the end of its operational life, the equipment will be recycled and the land the project occupies will be returned to its original state.

More information on solar energy is available at Innergex, the Solar Energy Industries Association, and the International Energy Agency.

Archaeological, Cultural and Environmental

Our passion to produce renewable energy stems from our profound belief that we can all make a difference in making the world a better place for future generations. At Innergex, environmental sustainability is a key part of our development strategy. We are driven by the belief that what we do matters as much as how we do it by developing projects that avoid, minimize, mitigate or offset the impacts on the surrounding area.

Innergex takes its environmental responsibilities very seriously and our facilities are developed and operated with strict adherence to environmental codes and best practices. This commitment explains why we conduct multiple surveys and studies of the surrounding environment in preparation for developing a project and we continue those efforts throughout the lifetime of the facility. We do so while abiding by all County, State and Federal regulations that apply to a project of this nature.

During early stage development, we conducted a preliminary archaeological desktop and reconnaissance field survey at the Project area. A Critical Issues Analysis was also completed which describes the existing environmental resources at the Project area and identifies regulatory requirements, issues, constraints, and limitations as they relate to the Project. We used these preliminary results to site the proposed Project in a location that minimizes environmental impacts.

Detailed archaeological, cultural, environmental and technical surveys and studies are required to assess potential Project impacts, required avoidance and minimization measures, design limitations, and to refine required permitting criteria. The results of the detailed surveys and studies will help identify any constraints as they relate to the Project and arrive at the best possible design of the Project that balances archaeological, cultural, environmental, social, technical, and economic considerations. We will then continue to seek applicable government permits and approvals based on the revised Project design and community input and feedback.

Several of these studies started in 2019 and others are ongoing throughout 2020-2021.

Initial drafts of the Archaeological Inventory Survey, Biological Resources and Delineation of Wetlands and Other Waters of the U.S. reports detailing the base line conditions are available in the Documents section below.

Community engagement efforts will continue throughout the development of the proposed Project.

Community and Potential Benefits

Innergex’s philosophy has always been to develop and operate reliable, high-quality projects while respecting the environment and balancing the best interests of host communities and partners. When developing a renewable energy project, Innergex has a successful track record of generating local benefits that go back into a community.

Construction and operation phases will create benefits in terms of new employment opportunities, as well as the use of local resources. Preference would be given to retaining local persons, consultants, businesses and contractors throughout the development of the project.

Innergex believes that communities must benefit from a renewable energy project in their area and as such we have a long history of sponsoring and supporting local associations, legacy projects and community events in the communities where we operate.

We are guided by our philosophy of supporting sustainable growth that creates a balanced relationship between people, our planet and prosperity. Investing in people and caring for our planet, while sharing economic benefits with local communities and creating shareholder value, have always been at the heart of our development strategy.

A project that will bring many benefits to the surrounding communities

In its approach that balances People, our Planet and shared Prosperity, Innergex aims to build long-term, high-quality projects that not only benefit the planet, but also have a positive economic impact on the surrounding communities and contribute to their economic development.

The County of Maui’s Maui Island PlanGeneral Plan 2030 states: “Renewable energy development will be critical to help the State of Hawai’i and Maui County reduce energy costs, avoid the negative economic effects of volatile oil prices, reduce overdependence on oil, and increase energy security by reducing imports.”

The Paeahu Solar Project will contribute to Maui’s renewable energy goals as called out in the Maui Island Plan and potentially offer additional benefits such as:

  • Productive Use of Unproductive Land. Maintaining large tracts of agricultural lands is a core value of Maui County residents. At the same time, the public acknowledges that farming on Maui is more difficult than ever with high costs of inputs, production, and shipping. Most residents do recognize the need for these landowners to diversify in order to keep their large land holdings intact. Renewable energy development is a low impact way of accomplishing this.
  • Lower Cost, More Equitable, Stable-Priced Energy Feeding the Grid. In the 2015 final report of the MPower Maui[1] process and the more recent series of more than 50 interviews conducted in preparation for the Paeahu Solar Project, residents emphasized that the cost of electricity is a prevalent concern. Projects like the Paeahu Solar Project are intended to contribute to lowering electricity bills over the long term. The price is less than Maui Electric’s current cost of generating power with fossil fuel and the price Innergex would charge per kWh will be set for 25 years.
    Those interviewed for the Project also emphasized the desire for electricity rates to be equitable and lower for all ratepayers. Even those who have installed PV systems on their residences were sensitive and concerned about residents who cannot afford rooftop PV systems and therefore benefit from the resulting reduction in electricity costs. The savings being shared by everyone on the grid through the Paeahu Solar Project is a positive response to this concern.
    [1] In May 2015, Maui Economic Development Board led a community engagement project called MPower Maui, An Energy Conversation. The project reached 435 residents through 43 small group sessions in a 30-day period.
  • Solar Farm as a Firebreak. One of the benefits of the project, with its planned, well-maintained buffers, is its role as a firebreak to lands in the area, given how vulnerable the South Maui region has proven to be during the most recent fires.
  • Battery Energy Storage Systems Can Reduce Curtailment. The recently-publicized curtailment of other wind and solar projects on Maui has been viewed by residents as a waste of energy generation—and investment—by the utility. These concerns underscore the importance of battery storage for projects like the Paeahu Solar Project in reducing curtailment. The stored power can be dispatched in the evening—when rooftop solar is not available—to help meet demands of residents returning home to deal with dinner, baths, washing, and other tasks or during emergencies.
  • Experience and Capacity. As a mature and experienced global company, Innergex brings necessary resources, capital, and expertise in the field of renewable solar energy. In addition, Innergex has a track record of working with indigenous and multi-cultural communities and shaping a win-win outcome with them. As captured in its core values, Innergex engages with a community, not as a developer, but as a long-term community partner for the life of the project.
  • An Opportunity for Workforce and Local Business. Throughout the life of the project, Innergex commits to using the local workforce and local companies wherever feasible, maximizing the investment in Maui. These opportunities provide invaluable experiences for workers and companies in an ever-expanding energy sector in Hawaii.
  • A Clean Power Future with Less Vulnerability. A great deal of concern exists among residents regarding Maui’s vulnerability to external threats because of its reliance on imported fuel. Harsh memories of shipping strikes, world oil prices, and geo-political forces stoke fears of the disruption these events could again cause to daily lives. Knowing that the sun is a readily-available, reliable resource, Maui residents are supportive of the utility harnessing a renewable resource to improve the island’s energy stability and grid resiliency.

Long-term benefits derived from this Project are expected to include the following:

  • The Project will help to meet the State’s renewable energy needs by providing up to 15 MW of solar energy and 60 MWh of battery storage, which is enough to provide electricity for approximately 6,900 Maui homes. In doing so, it will directly contribute to the State’s renewable energy goals, fulfilling an average of 3.9 percent of Maui Electric’s Renewable Portfolio Standard (RPS) over the 25-year term of the PPA and 0.5 percent to Hawaiian Electric’s consolidated RPS.[2]

Available: https://dms.puc.hawaii.gov/dms/DocumentViewer?pid=A1001001A19A03B45131D00299
  • The solar energy from the Project will replace a portion of electricity that is currently generated by burning fossil fuels, thus substantially reducing greenhouse gas emissions and other forms of pollution that are detrimental to the environment and human health. In total, the Project is expected to reduce net lifecycle greenhouse gas emissions by approximately 527,810 metric tons of carbon dioxide equivalents over its lifecycle.[3]
    [3]  See Maui Electric Company’s Direct Testimonies and Exhibits filed on September 17, 2019, Testimony of Abigail Kirchofer filed as MECO T-5 Exhibit MECO-204 filed in Docket No. 2018-0433 on September 17, 2019
  • It is estimated that the renewable energy supplied by the Project will potentially save Maui Electric, and therefore customers, millions of dollars in total avoided fuel costs over the term of the PPA based on a forecasted fuel consumption reduction of 1,342,000 fewer barrels of fuel.[4] The avoided fuel use and changes to Maui Electric’s system costs due to the addition of the Project will results in a significant reduction in the net present value (“NPV”) of revenue requirement for Maui Electric.[5] Specifically, Maui Electric presented uncontroverted evidence that the updated Company system NPV with the Project (versus without the Project), will result a reduction of Maui Electric’s revenue requirement over the 25-year contract term of $26,463,496.[6] These savings result in bill savings to the customers over the 25-year term of the PPA.

  • A reduction in fossil fuel consumption due to the Project will in turn reduce the need for fuel imports, reduce fuel supply reliability risk, and increase the State of Hawaii’s and Maui County’s energy independence.
  • The Project will also help to improve electric grid stability by enabling Maui Electric to utilize stored solar energy to meet peak demand.
  • The Project’s long-term lease agreement with Ulupalakua Ranch will provide a valuable revenue stream for the ranch over the next 25 years or more to maintain ranch jobs, and help create sustainable, diversified uses of the less productive areas of their land in order to continue its operations and conservation efforts.

Community Outreach and Engagement

With its sustainable approach to renewable energy projects, Innergex engages with surrounding communities and seeks their input to build projects that are welcomed and accepted by a majority of People.

The intention of Innergex, in conjunction with Ulupalakua Ranch, has been to engage with the local communities to proactively foster their understanding of the Paeahu Solar Project, seek their input, understand local values, and discover areas of mutual interest through open, two-way communication.

Innergex continues to engage in extensive outreach efforts. These efforts have focused on one-on-one interviews, community information sessions (open houses), and multiple meetings with community organizations. A summary of the dates of community information sessions and links to presentation material are detailed below.

Frequently Asked Questions

See the Frequently Asked Questions handout for details and background information.

What is the Paeahu Solar Project?

Innergex is proposing a 15 MW solar photovoltaic and 60 MWh battery energy storage system project on Ulupalakua Ranch, mauka of Piilani Highway in South Maui, under a land lease agreement. The project will be located on approximately 150 acres of ranch land.

Why was Ulupalakua Ranch selected as the location for this project?

Ulupalakua Ranch was selected because it has an excellent solar resource, buildable land, existing Maui Electric infrastructure (i.e. substation and transmission line), and Ulupalakua Ranch’s interest in creating sustainable, diversified uses of the less productive areas of their land. In addition, Maui Electric identified the need for regional electricity generation in South Maui due to load growth and constrained transmission capability.

What led to this project being developed?

Innergex responded to a Request for Proposal (RFP) issued by Maui Electric Company, Ltd (“Maui Electric”) in 2018 for renewable energy that will help stabilize and lower costs while reducing the state’s reliance on imported fossil fuels and cutting greenhouse gas emissions.

Who is Innergex?

For 30 years, Innergex has believed in a world where abundant renewable energy promotes healthier communities and creates shared prosperity. As an independent renewable power producer which develops, acquires, owns and operates hydroelectric facilities, wind farms, solar farms and energy storage facilities, Innergex is convinced that generating power from renewable sources will lead the way to a better world. Innergex conducts operations in Canada, the United States, France and Chile.

Who is funding the Paeahu Solar Project?

Innergex will be responsible for 100% of the development, construction, and start-up costs. After completion, Innergex will also be responsible for all operational and maintenance costs.

Will this mean increased costs for consumers?

Maui has some of the highest electricity prices in the United States at 35 cents per kWh. The price of solar plus battery energy storage in the Maui Electric RFP is the lowest to date for renewable electricity in the state. The Project will provide a fixed, long-term price of 11.7 cents per kWh, in place of the volatile prices of fossil fuels. This is more than 20% lower than Maui Electric’s current cost of generating electricity which will put downward pressure on electricity rates.

What will the Project accomplish?

The Paeahu Solar Project will power approximately 6,900 homes with renewable energy. This will contribute to the State of Hawaii’s goal to achieve 100% renewable energy by 2045 and reduce the state’s dependency on imported fossil fuels. The project capitalizes on an abundant solar resource which is the least expensive form of renewable energy available in Hawaii today.

How else will the community benefit from the Paeahu Solar Project?

In keeping with Innergex’s core values, preference will be given to local suppliers and contractors throughout the development of the project. The project will also contribute to local organizations, community projects and events throughout the life of the project.

Why are batteries part of this project?

The battery storage system was a key aspect of the RFP. The batteries would be completely charged from the solar panels during the day. The energy can then be used during peak demand in the evening or at other times when the sun is not shining.

Are there any cultural or environmental features to consider for the site?

Respecting the archaeological, cultural, and environmental features of any site that Innergex develops is a priority. As such, archaeological, cultural and environmental studies and analyses are ongoing for gaining a thorough understanding of the site. The intent is to arrive at the best possible final layout that balances archaeological, cultural, environmental, technical, economic and social considerations.

What is the timeline for the Project?

Innergex responded to Maui Electric’s Request for Proposal in April 2018 and, after meeting other milestones, was awarded a Power Purchase Agreement in December 2018. Innergex anticipates completing construction and beginning operation of the project by June 2022.

How long will Paeahu be in operation?

The Project’s power purchase agreement (PPA) with Maui Electric will have a term of 25 years. Thereafter, the project can be acquired by Maui Electric, have its PPA renewed, or be decommissioned, recycled and returned to its original state.

Community Feedback


  • The solar array racking system design was changed from single-axis trackers to fixed-tilt.
  • Fixed-tilt systems have the advantage of being slope tolerant and can be installed in a more compact space compared to single-axis trackers. Due to the topography of the site, the use of fixed-tilt foundations allows for a reduced Project footprint; thereby allowing more flexibility on the micro-siting of the solar array.
  • The Project layout has been designed to take into account the results of the archaeological and environmental studies (see attached figures).
  • The solar panels will occupy about one-quarter of the approximately 200-acre study area.
  • June 2020 Project Update Letter.
  • The Project is planning to use a temporary access road outside of Maui Meadows during construction.
  • Use of Piilani Highway during construction would be temporary and would try to avoid peak traffic hours.
  • During operations the site requires only minimal access by light-duty vehicles.
  • Best management practices will be used during construction and operation such as scheduling deliveries for non-peak hours of traffic, minimizing the number of vehicles on roadways.
  • A traffic Impact Analysis will be completed as part of County Special Use Permit application.

Setbacks Increased

  • The initially-proposed setback to the solar panels was 200 feet, this revised project layout has now increased the setback to be a minimum of 300 feet away from the property line or equivalent to a football field away.
  • Existing vegetation between the fence lines will be preserved which further reduces the visibility of the Project from the Maui Meadows homes adjacent to Ulupalakua Ranch.
  • We remain committed to the solar array height being about 8-9 feet (reduced from about 16 feet) to keep them at the approximate height of the existing tree line.

Refer to the June 2020 Project Update – Revised Project Layout

View Plans Mitigated

  • The Project will be partially visible from select locations.
  • We developed visual (photo) simulations of the project through an experienced engineering firm to understand the potential views from the homes along the border of the ranch land and shared them with the community. Updated visual simulations are being prepared based on this design layout and we look forward to sharing them with the community this summer.
  • We committed to adding additional vegetation to the existing vegetation buffer between the property line and the Project fence line where beneficial to mitigating view planes of the select homes directly adjacent to the ranch that may be affected.
  • Homes that border the ranch will have potential views of the project. All the other homes within the neighborhood will have no view of the project as Maui Meadows is on a hillside and the combination of all the other houses being below the natural elevation of the ranch and the row of adjacent houses to the ranch block views.

Refer to the Visual (Photo) Simulations


  • Although noise related to the single-axis trackers was not expected to be audible from any neighboring residences, we took this concern into consideration and switched our design to fixed-tilt foundation. This change eliminates the potential for noise from the solar tracker motors.
  • The solar panels will have an anti-reflection coating.
  • With the fixed-tilt foundations, the potential glint and glare from the panels will be mitigated by the anti-reflective coating on the panels and by design and modifications of the array azimuth or direction in which the panels face (south-east).
  • The Project design accounts for potential glint or glare and follows guidance developed by the Federal
    Aviation Administration (FAA).
  • Preliminary analysis that simulated the perspective of nearby residences did NOT find any glint or glare issues.
  • Detailed analysis will be conducted on the revised project layout and if any issues are identified then measures will be taken to mitigate them.
  • Preliminary meeting was held with the Maui Fire Department to discuss fire protection and risk
    reduction in which the department noted the project would act as a firebreak to Maui Meadows.
  • A fire safety plan will be implemented. We will work with the department to identify and mitigate safety
    risks to prevent incidents and protect employees, first responders, the public and the environment.
  • A site visit with the Fire Department will be held to review procedures for different types of potential
  • The Project’s battery energy storage system has been designed to comply with national fire safety
    standards and best safety practices including proper training for operators and first responders.
  • Battery storage to be used at the Project site has undergone stringent safety testing and are designed for
    commercial and outdoor use and will utilize liquid cooled lithium-ion batteries enclosed in multiple
    smaller steel cabinets to mitigate fire spread in the case of an external or internal fire event.
  • Battery supplier has completed a full-scale hazard assessment of its battery system by the US
    National Fire Protection Association (NFPA) that included both internal and external fire attack
  • Required archaeological, biological, technical, and site-specific surveys and studies are underway to
    assess potential impacts, mitigation measure, design limitations, and meeting permitting criteria for the Project.
  • Site-specific plans will be prepared to address potential impacts (e.g. spill and stormwater prevention, erosion and sediment control).
  • Innergex is regularly consulting with the Aha Moku, environmental groups, and other stakeholders on to these surveys and studies.

Refer to the Studies, Surveys & Technical Memorandums

  • The Project will not change the local climate or affect the natural flow of air across Maui Meadows or southern Maui.
    The up- and down-slope winds off Haleakala would overwhelm any heat creation from the solar farm.
    The Project area is simply too small in relation to the area of the southwestern slope of Haleakala to
    have a significant impact on the natural air movement across Maui Meadows and the larger Wailea area.
  • The Tetra Tech Memorandum RE Heat Island Effect in Context to the Proposed Paeahu Solar Project, Maui County, Hawaii dated December 12, 2018.

Refer to the Tetra Tech Memorandum RE Heat Island Effect in Context to the Proposed Paeahu Solar Project, Maui County, Hawaii dated December 14, 2018.

  • EMF levels in the local area will not change as a result of the Project. Electric facilities produce EMF,
    as do household appliances and electrical lights. The Project will produce low levels of DC EMF from
    panels and collector lines, and AC EMF from inverters, battery energy storage system, transformers, and power lines.
  • Levels of DC EMF produced are significantly less than the Earth’s magnetic field. Levels of AC EMF also decrease rapidly with distance and point sources will be 625 – 3,000 ft from the Maui Meadows neighborhood. As a result, no electric or magnetic fields created by the project will be measurable at any residences.
  • The term “dirty” power is used to describe electricity containing high radio frequency noise. “Dirty” power is commonly produced by household electronics such as computers. Utility-scale power generators such as solar farms must meet national power quality standards and include high frequency voltage filtering. Project equipment must meet federal radio frequency standards and any low levels produced dissipate near the source, leaving no measurable levels at the project boundary.
  • Innergex followed-up with the two companies put forward by Dr. Debra Greene: Cratus Canada on December 12, 2018 and Satic Inc. on December 13, 2018. Satic agreed that the proposed project at these distances are far enough away to not have an impact on the neighboring residences. Innergex requested that they provide additional information for review and consideration.
  • Refer to the Tetra Tech Memorandum RE EMF and ‘Dirty Power’ in Context to the Proposed Paeahu Solar Project, Maui County, Hawaii dated December 15, 2018.

Refer to the Tetra Tech Memorandum RE EMF and ‘Dirty Power’ in Context to the Proposed Paeahu Solar Project, Maui County, Hawaii dated December 15, 2018.

  • Two property impact analyses have concluded that the Project is not expected to have an adverse effect on nearby property values.
  • An analysis was conducted by CohnReznick to quantify changes in adjacent property values upon the construction, operation, and overall presence of a solar facility in various locations in the United States. The study locations represent California, Hawaii, Indiana, Minnesota, and New York in a variety of market conditions to ensure an unbiased and distinct sample size.
  • Property values for parcels adjacent to an existing facility were analyzed (as well as in various phases of construction where possible) as a test group and compared with properties outside of the vicinity of any solar project as the control group using indicators. In order to take into account market fluctuations due to time and location of sales, a regression model was used to scale price and demand for properties and ensure comparability. Impact to property value was measured in differences in range of sale prices, unit sale prices, conditions of sale, and overall marketability between the control group and the test group.
  • In all areas studied, it was conclusive that proximity to an existing solar facility did not have an impact on property values.  This conclusion was reaffirmed by property assessment and sales professionals.

Refer to the CohnReznick Property Value Impact Study dated May 2020.

  • Colliers International analyzed tax assessment and property sale values for properties adjacent to two
    recent utility-scale solar projects in Hawaii (Waianae and Waihonu). Residential properties adjacent or
    in close proximity to the solar farms increased in value over 3-4 years between 8% to 35%.

Refer to the Colliers International Memorandum RE Market Pricing Study: Property Tax Assessment & Price Changes to Land Adjacent to Solar Farms dated November 22, 2018.

At present, Innergex anticipates that upon completion of construction and during normal operations of the Project there will only be security lighting in use for the Project. The Project is expected to include a security fence with gates. A security light will be installed at the gate(s). Depending on the location along the fence line, the light will be at least 250 feet away from the nearest residence.

The light will have a motion sensor which will activate for the safety of authorized personnel, in those rare circumstances, that they may need to access the site at night. In addition, light from the security light will be shielded and directed downward to prevent upward radiation, and fitted with non-white light bulbs to the extent possible. Lighting should be situated so that light does not shine on and reflect off the solar panels. Thus, even assuming light from the security light can be seen from Maui Meadows residential development, it is not expected to have a significant impact on recreational stargazing or other similar activities by nearby residences. Apart from the security light at the gate(s), no other security lights, or any other types of lights or lighting, will be used after completion and during regular operation of the Project unless otherwise directed by Maui Electric Company or code compliance.
