PUBLIC BUILDING
The Phillip Burton Federal Building in San Francisco is the largest federal building in the western US. Built in 1959 this 21-floor multi purpose federal facility has a 24/7 demand for both electricity and heat. A study was completed to first capture and measure the facilities’ energy usage, then select the technology to best fit the load profile and achieve the maximum available energy savings. The Flex turbine MT250 gas turbine was chosen. It provides round the clock power and heat thereby reducing base load power consumption by 250 kW/ht and also generates up to 1.100.000 Btu/hr of hot water for space heating.
Results:
Annual Energy profit $275.000

FACTORY
The Ethicon facility in Cornelia, Georgia – a Johnson & Johnson Company- manufactures surgical and medical instruments. In the process, Ethicon uses both heat and electrical energy on a consistent 24X7X365 basis. The FlexEnergy Inc MT250 gas turbine became an obvious choice as a consistent provider of on site heat and electrical energy. They installed two MT250 gas turbines that deliver 2.200.000 Btu/hr as part of a modified exhaust system that feeds a steam boiler. The heat energy generated by the gas turbines aids in the sterilization process by reducing the amount of natural gas that the existing steam boilers consume for regular operation.
Results:
Boiler Savings: $ 150.000/year
Annual Energy Savings: $ 350.000/year

HOSPITAL
The John Muir Medical Center’s Walnut Creek campus is an acute-care 324 bed facility that in 2007 began construction for a Central Utility Plant expansion with a plan to increase energy efficiency and reduce grid-purchased power. A feasibility study was conducted to predict the facilities’ power and hot water usage, then selected the technology that generates reliable output to best fit the defined profile.
3 Flex Turbine MT250 configuration for a total of 750kW/hr won the bid. To help fix cost and maximize uptime, hospital agreed to a Total Care Service Agreement with FlexEnergy Inc for its low maintenance gas turbine system.
Results:
Boiler Savings: $ 200.000/year
Annual Energy Savings: $ 350.000/year


LABORATORY / OFFICE BUILDING
EMERYSTATION, EMERYVILLE, CA Laboratory / office building
Wareham Development, a forward-looking real estate firl based in San Francisco Bay Area, were seeking to offer their tenants the unique benefit of low cost energy. Distributed generation was chosen to produce the desired result. It limits cost exposure to future rate increases and the thermal energy generated from combustion can be used for space or process heating  for the EmeryStation facilities. By installing 3 250kW MT250s Wareham Development benefits from secure power energy savings and reduced energy cost volatility. The tenants benefit from ultra-clean onsite, reliable power and an installation that is unobtrusive. All 3 units are natural gas fired.
Results:
Annual Emissions: $ 200.000/year
Annual Energy Savings: $ 50.000 to 60.000/year in energy

LANDFILL GAS TO ENERGY
Toland Road Landfill Ventura county CA
Ventura Regional Sanitation District wanted to take advantage of all the landfill gas as it became available rather than waiting 5-10 years for the optimal flow required for a large scale reciprocating engine. With installation of the FlexTurbine system, Ventura County affirms its’ commitment to renewable energy and environmental stewardship. The partnership with Flex Energy will continue to pay dividents in future years as the 9 commissioned 250kW MT250 turbines will increase to 15 to meet the full capacity of Toland Road Landfill.
Results:
Annual Emissions: CARB certified for operation on landfill.
Annual Energy Savings: $ 1.9MM/year in energy savings.
Renewable Portfolio Standard: 2,25 MW towards California’s overall renewable energy goals.
