Harris Township authorizes 60% share of regional solar PPA after prolonged debate over economics and RECs
Summary
After a multi‑hour presentation and public debate about costs, green‑attribute ownership and contract length, the board authorized township staff to execute PPA documents committing Harris Township to purchase 60% of its electricity from a 15‑year solar power purchase agreement (Prospect 14) with Direct Energy servicing and GreenSky managing RECs.
The Harris Township Board of Supervisors authorized township staff to prepare and execute Power Purchase Agreement (PPA) documents committing the township to a 15‑year contract for a portion of electricity from a regional solar array (identified in materials as Prospect 14). The board authorized documents to pursue a 60% purchase commitment as presented by the PPA working group.
Staff described the PPA package as a tri‑party arrangement: Prospect 14 (solar developer) will build a roughly 18‑megawatt array; Direct Energy will act as the retail servicer; and GreenSky (the broker) will monitor invoices and compliance. The PPA contains a fixed PPA price with a small annual escalator and assumes any portion not covered by the PPA is supplied at market rates under a five‑year retail contract. The working group estimated an initial delivered rate in the 7.6–7.9¢/kWh range depending on commitment tier, projected modest savings versus the board’s modeled 8¢/kWh market baseline, and an estimated payback period of roughly 8–9 years under the group’s assumptions.
Board members, the public and working‑group members debated several issues:
- REC ownership: the working group explained Prospect 14 will retain renewable energy credits (RECs) to reduce the PPA cost; the township would buy RECs separately if it wants to claim carbon‑neutral scope‑2 emissions reductions. Staff summarized recommended language that the township may say it is "helping to green the grid" while buying RECs elsewhere to meet scope‑2 accounting.
- Contract length and management risk: critics warned a 15‑year exposure could lock future boards into an unfavorable rate or relationship; supporters said the lengthy contract provides revenue certainty necessary to finance the solar project and yields modest projected savings and greenhouse‑gas reductions.
- Environmental lifecycle concerns: some questioned whether panel recycling and end‑of‑life impacts undermine the project’s environmental benefits; staff and board members noted panel recycling capability exists and that lifecycle impacts are a broader sector issue.
After discussion and a motion to authorize the manager to prepare and execute the PPA documents at a 60% commitment level (Resolution 24‑13), the board approved the authorization by voice vote (board recorded as split votes on the record: three in favor, two opposed). The motion instructs staff to finalize documents and permits the manager to sign as directed once solicitor review is complete.
What this means for township net‑zero claims: staff emphasized that because Prospect 14 will retain RECs, Harris Township would need to acquire RECs separately (through GreenSky or other markets) to account for scope‑2 emissions; the PPA participation alone does not automatically allow the township to claim 100% renewable electricity for greenhouse‑gas accounting.
Next steps: Manager and solicitor will complete contract review and closing checklist items (tri‑party agreements, servicing agreements and board resolution/authorization) and report back to the board. The township will also finalize the chosen percentage of commitment for ongoing budget planning and cash‑flow projections.
