About GridArb

GridArb is built by one person: Rudra Patel, in Sayreville, New Jersey. It started in October 2026.

Why

A New Jersey battery is a $5 million decision for a 5 MW site, and the first question is always the same: is this site worth the study deposits, the lawyers and the vendor quotes? The honest answers today cost tens of thousands of dollars and arrive months later. GridArb gives a cheap, honest first check in minutes: real PJM prices through a real dispatch optimizer, the capacity, Regulation and incentive rules as published, costs from a named benchmark or your own quote, and a plain list of what it cannot know.

The sample report

GridArb gives recommendations. It does not bid into PJM or sign anything for you. A report is a screening check before you spend on a site, not a bank-ready revenue study.
