Texas is in the middle of an unprecedented power demand surge. AI data centers, crypto operations, and expanding oilfield activity are competing for limited generator inventory. While competitors quote 60-day lead times, Caliper deploys in days. Our fleet is maintained, ready, and backed by 24/7 field support. ISNetworld verified and operating from Houston, San Antonio, and Lufkin — we cover all of Texas.
50 kW to 400 kW units available for short-term, long-term, and emergency deployment anywhere in Texas.
We don't just drop a generator and leave. Our crews handle delivery, placement, fuel connection, and commissioning. Your site is producing power the same day.
Generator down at 2 AM? We answer. Our field technicians are on call around the clock to keep your operations running.
Our units run on wellhead natural gas — no diesel logistics, no fuel trucks, no waste. Use the gas you're already producing.
