The buyer hurts here

Industrial batteries are bought blind, then operated by spreadsheet.

Sizing is a wild guess.

A 4 MWh purchase decision is made from a one-page utility bill and a vendor sales sheet. Most plants land on 30% to 60% under-sized within two years.

52% of post-install regrets cite under-sizing

Peak shaving runs on autopilot.

Stock battery firmware ships generic dispatch curves. Plants that could earn $400K a year in demand-charge cuts capture $90K to $150K and never know the gap.

60% to 75% revenue left on the table

Warranty data is a black box.

Owners learn cells are degrading from a vendor email six months after the fact. By the time a claim is filed, the warranty window has shifted and the value of the asset has dropped 12% to 18%.

Average claim is filed 7 months late

03 of 14 · Why Now
Three curves crossed this year

Industrial battery storage is suddenly the cheapest tool a plant has.

SHIFT 01

Battery cost crossed the operating cost of a peaker plant.

$330 / kWh, 2020 to $118 / kWh, 2026

Lithium iron phosphate is now the default chemistry for industrial sites. ROI math that needed 9 years now needs 28 months.

SHIFT 02

FERC Order 2222 brought distributed assets into wholesale markets.

Behind-the-meter only to PJM, ISO-NE, CAISO live

The same 4 MWh battery now stacks demand-charge savings with day-ahead ancillary revenue. Two revenue streams from one asset.

SHIFT 03

IRA Section 48E pays a 30% to 50% credit on storage placed in service.

No storage credit, 2022 to $36B installed pipeline, 2026

Industrial buyers are signing 2026 orders today. The question is no longer whether to deploy storage. It is which operator owns the analytics layer.

04 of 14 · Solution
What we do

The analytics layer that makes every industrial battery earn its full revenue.

Greenroot reads the live signals coming off any battery, any inverter, any utility tariff. We turn that stream into a daily dispatch plan that captures 2 to 3 times the revenue a stock controller would.

No new hardware. We install behind the meter in under a day and start earning within a week.

Right-size before they buy.

30-day load study from a single CT clamp. Spec the asset that pays back in 30 months, not 80.

Dispatch every hour, every tariff.

Live demand-charge shaving plus wholesale arbitrage, tuned to the plant's actual production schedule.

Warranty defense, built in.

Cell-level degradation reports filed automatically. Claims land in 18 days, not 7 months.

What competitors cannot copy in six months

Three compounding moats, each tied to data we already own.

Proprietary degradation corpus

1.4 billion cell-cycles observed across six OEM chemistries. The corpus that lets us predict cell failure 90 days early grows every minute every site is live.

1.4B cycles · 6 OEMs · 26 sites

Tariff library

412 US utility tariffs decoded into structured rules. New entrants need three years and an army of analysts to rebuild what we already ship in production.

412 tariffs · 47 states · updated daily

Switching cost on a 10-year asset

The battery sits for 10 years. The first analytics layer to prove itself owns the dispatch contract for the life of the asset. We are first on every site we win.
