Diesel only moves one way — up.
Fuel prices climb year after year, and every hike lands on your bill. Our per-unit rate is fixed for the entire term — no fuel surcharges, no escalation, no surprises.
Drop-in for your DG
LiFePO4 systems sized to replace 50 kVA–5,000 kVA diesel sets. Instant switchover, no fuel, no soot, near-silent — designed for industrial duty.
Zero investment
You pay nothing upfront. Just a fixed per-unit rate — billed exactly like your diesel, except about half the cost. We own, install, and maintain the battery system.

After a 5-year term we transfer the system to you outright. It's built for a 10-year life — so you keep 5 years of effectively free power.
