Financial Payback and Annual Savings for the Infinity Turbine IT250, IT1000, and IT10MW Systems

Financial Payback and Annual Savings Analysis

A detailed look at operating costs, annual savings, and payback periods for Infinity Turbine systems ranging from 250 kW to 10 MW, showing how high efficiency supercritical CO2 turbines outperform purchased grid electricity.

Financial Payback and Annual Savings Analysis

Below are the assumptions used for the comparison:

Key Assumptions

• Heat rate: 10,000 BTU per kWh

• Natural gas price: $10 dollars per MMBTU (average US commercial retail rate)

• Electricity value: $0.20 dollars per kWh

• Continuous operation: 24 hours a day, 365 days a year

• Hours per year: 8760

Gas Fuel Cost per kWh

10,000 BTU per kWh equals 0.01 MMBTU.

Natural gas at $10 dollars per MMBTU results in a fuel cost of $0.10 dollars per kWh.

Value of Produced Electricity

Electricity worth $0.20 dollars per kWh.

Fuel cost $0.10 dollars per kWh.

Net savings per kWh produced: $0.10 dollars.

Annual Operating Savings

Savings = Output in kW multiplied by hours per year multiplied by savings per kWh.

IT250 System

• Output: 250 kW

• Annual kWh: 250 x 8760 = 2,190,000 kWh

• Annual savings: 2,190,000 x $0.10 = $219,000

IT1000 System

• Output: 1,000 kW

• Annual kWh: 1,000 x 8760 = 8,760,000 kWh

• Annual savings: 8,760,000 x $0.10 = $876,000

IT10MW System

• Output: 10,000 kW

• Annual kWh: 10,000 kW × 8760 h = 87,600,000 kWh

• Annual savings: 87,600,000 kWh × $0.10 = $8,760,000

Payback Period Calculations

Payback equals system cost divided by annual savings.

IT250

• Cost: $999,000 dollars

• Annual savings: $219,000 dollars

• Payback: $999,000 divided by $219,000

• Payback: 4.56 years

IT1000

• Cost: $3,000,000 dollars

• Annual savings: $876,000 dollars

• Payback: $3,000,000 divided by $876,000

• Payback: 3.42 years

IT10MW (10,000 kW system, $30,000,000 USD)

• Annual electricity produced

10,000 kW × 8760 h = 87,600,000 kWh per year

• Annual savings

87,600,000 kWh × $0.10 = $8,760,000 USD per year

•Simple payback

$30,000,000 ÷ $8,760,000 = 3.42 years

Summary

Using a heat rate of 10,000 BTU per kWh and a standard commercial natural gas price of $1.00 per therm, the cost to generate power is approximately $0.10 per kWh. When compared with a grid electricity rate of $0.20 per kWh, users save $0.10 for each kilowatt hour produced on site. For continuous year round operation, the IT250 yields savings of $219,000 dollars per year with a payback of 4.56 years. The IT1000 and IT10MW systems achieve payback in about 3.4 years with annual savings of $876,000 dollars and $8.76 million dollars respectively. These results show that natural gas turbine generation provides substantial economic benefits for data centers, industrial users, and any facility operating around the clock.
