Questions

Does GridArb bid for me?: No. GridArb recommends: where to build, what size, and what it earns. It never bids into PJM, signs anything, moves money or contacts anyone for you. You decide and you execute.
What do I get for $500?: The full report for one site: two years of real PJM prices through the dispatch engine, capacity, Regulation and NJ incentives with low / base / high, cost and payback at the NREL benchmark or your quote, the grid-connection picture, and a note from GridArb after a human review. Delivered as a private link within 24 hours of payment.
Where do the numbers come from?: Real PJM day-ahead and real-time prices for the four New Jersey zones, PJM capacity auction results and ELCC rules, and NREL Annual Technology Baseline cost benchmarks. Every report names its sources. The assistant may only repeat numbers that GridArb's engine produced in your conversation.
Are the revenue numbers a promise?: No. They are backtests on two years of real prices. Energy arbitrage is shown at 80% of perfect foresight, and the 15-year view gives low, base and high scenarios. Interconnection upgrade costs, permits and real vendor quotes are not modelled.
What do you store about me?: Your chats, the site details you give and the results, so you can come back to them. Anonymous visitors get a random cookie ID; no IP addresses are stored. You can delete your data at any time. See the privacy page.
