USFWS to Hawaii: Risks to endangered species from wind

This important letter to the Hawaii PUC warns that wind projects operating in the State are impacting endangered species. To address this situation, US FWS askes the PUC to delay approval of any new wind facility contracts until the proponents make the time to meet with the Service. A portion of the letter is provided below. The full letter can be accessed by selecting the documents link(s) on this page.

Letter Excerpt

Renewable wind energy projects across the State of Hawaii are witnessing higher than anticipated take (e.g., harm, injury, or death) of the Hawaiian hoary bat and other listed species. As a result, the Service and Hawaii Department of Land and Natural Resources, Division of Forestry and Wildlife (DLNR DOFAW) need time to coordinate with each wind project proponent in order to allow for a timely and effective permitting process.

The Service understands that it is the sole responsibility of the independent power producer to complete all environmental compliance steps, and report on the progress of environmental compliance to HECO. However, HECO has not been coordinating with the Service and DOFAW to verify that a wind energy producer has completed the necessary compliance procedures. It has been our experience that wind project applicants do not approach the Service and DOFAW until after finalizing their PPA. Therefore, in most instances, at the time the PPA is submitted to the PUC for approval, the project proponent is still in the process of obtaining Federal and State endangered species permits.

Once the PPA is issued, a Commercial Operations Date or other project implementation deadline and minimum power generation thresholds are set. Due to the endangered species impacts we are currently documenting at other wind facilities, the permitting process for receiving the appropriate federal and state permits arc complex, and may require halting operations during certain times of the day and/or year; implementing low wind speed curtailment regimes; or other measures that limit production ability and affect power production costs. Additionally, for any impacts to listed species that cannot be avoided, permittees are required to offset this impact with compensatory mitigation. Again, the development of these mitigation plans can be complex and challenging to develop, especially if an applicant has already finalized their PPA. These PPA requirements can severely restrict the applicant’s ability to appropriately develop and implement endangered species permit avoidance, minimization and compensatory mitigation measures. This circumstance has led to several existing wind energy facilities operating without the appropriate or in violation of their State and Federal endangered species permits and limits the conservation measures that can be implemented by the wind facilities to reduce impacts.

We believe these challenging circumstances can be avoided with early coordination between the wind energy proponents, the Service and DOFAW prior to negotiation of the PPA with HECO and approval by the PUC. This early coordination would greatly assist proponent’s planning efforts (including operations, power production and financial expectations), make permitting processes and timelines more efficient (less time and cost), and may assist the wind energy company with siting or structural modifications to reduce environmental impacts, increasing the likelihood they can successfully apply for and obtain the necessary endangered species permits. Together, we anticipate these efficiencies will enhance and support the PUC’s approval process by increasing the certainty that projects seeking PPA approval will be able to generate the amount of power and be able to be operational within a specified timeframe.

To address this situation, we ask that the PUC delay approval of any new wind facility PPAs, including the recently submitted Palehua wind facility project, until the project proponent has met with the Service and DOFAW.
