Monitor for a contract announcement within the 7-day negotiation window (by June 19, 2026). A successful agreement would be a significant catalyst, while failure could reverse gains. The PREB's threat of fines increases the probability of a deal.
Price Chart
Executive Summary
Greenbriar announced that the Puerto Rico Energy Bureau (PREB) has ordered PREPA and the company to complete negotiations within 7 days for a 40 MW battery storage system, with pricing specified at $24,000/MW/month (4-hour) and $33,000/MW/month (6-hour). The order includes a warning of fines for PREPA non-compliance, increasing the likelihood of a contract. This is a positive regulatory catalyst that could lead to material revenue, separate from an existing 80 MW solar contract.
