Estimates, not advice

GridArb's results are estimates from backtests on past prices and published rules. They are not financial, legal or engineering advice, and past prices do not guarantee future revenue.

You decide and you execute

GridArb gives recommendations. It does not bid into PJM or sign anything for you. It does not move money or contact utilities, PJM or anyone else for you. Any bid, contract or dispatch is your decision and your action (or your operator's).

What is not modelled

Interconnection studies and upgrade costs, permits, site work, real vendor quotes, taxes beyond the ITC rate you choose, and regulation revenue. Check these before you commit money.

Fair use

Plans have the monthly limits shown on the plans page. Automated scraping and attempts to get around the limits are not allowed.

Payments

Paid plans open the payment provider's checkout when it is available; until then, Request access sends your details to the GridArb operator.
