GridPinn
Behind-the-meter energy storage, financed, installed, and operated for demand-charge relief

Commercial and industrial electricity bills are dominated by demand charges: the kilowatts you peak at each month. A battery that shaves 30 minutes of peak demand pays for itself in a few years. Most businesses can’t front the capital, don’t want to operate the asset, and don’t have someone in-house who understands dispatch.
The thesis: Sell a demand-charge reduction service. The battery is an implementation detail. GridPinn finances, installs, and operates the storage. The customer signs a long-term bill-split contract. Everyone wins: the customer gets a lower bill with zero capex, GridPinn captures the spread, utilities get a predictable peak-shaving asset.
What was built: Landing page, pitch, financing model sketch. See gridpinn.com.
Why it’s parked: This is a capital-heavy business that needs project financing, utility relationships, and a team that can deploy hardware. The thesis is sound. If you’re in cleantech finance or storage ops, take it.
