Municipality/ Wastewater Treatment Plant
MISSION CRITICAL POWER
In an emergency, seconds can save lives. Leon County and the City of Tallahassee needed backup power for their new 90,000 sq-ft Public Safety Complex. They chose Cat® power systems. Working with their local Cat dealer and building managers, they developed a reliable, fuel-efficient system, so no call is ever dropped – even during a loss of power.
How It Works
A durable engine specifically designed for use with low-energy fuel is the cornerstone of a reliable power system. That engine drives a Cat generator to produce electricity for standby power for municipal buildings.
Cat low-energy fuel generators offer a specialized tolerance to the contaminants in sewage gas fuels by offering additional features that include:
- Crankcase ventilation pump to eject potentially acidic blow-by gases
- Specially designed aftercooler cores, cylinder heads, main bearings, and connecting rod bearings that are hardened against corrosive elements
- Differentiated cooling systems to operate at elevated jacket water temperatures to prevent condensation of contaminants
Heated engine jacket water passes through a plate-and-frame heat exchanger that is connected to the treatment plant's process heat loop. Additional heat can be recovered from the aftercooler circuit as well as the engine's exhaust. The system is typically electrically integrated into the facility via Cat utility grade paralleling switchgear with PLC-based controls that allow electricity to be exported to the grid or used exclusively by the facility.

Biogas Project of the Year
Monogram Snacks has leftover oils and fats that need disposal. To avoid incurring high monthly surcharges for processing wastewater, Monogram built a new clean energy plant. An anaerobic digester breaks down the waste and converts it to methane gas, which is used to fuel a Cat® CG132-08 gas genset, saving on their utility bill. Monogram Foods was recently recognized as the “Biogas Project of the Year” by the American Biogas Council. The Biogas Project of the Year honors an operation that strongly exemplifies financial ingenuity, energy efficiency and sustainable waste treatment.

Providing reliable standby power during extreme weather
The Leon County Government and the City of Tallahassee combined the 911 dispatch and emergency response functions from both locations at a new 90,000-sq-ft Public Safety Complex to improve emergency response time. To provide support for all emergency service functions, the complex requires on-site reliable standby power to continue operations in case of power loss.

Cat® power is always ready
In 2005, Hurricane Katrina brought storm surges between 12 and 15 feet to the New Orleans area. In 2012, the U.S. Army Corps of Engineers awarded a contract to Caterpillar to build three permanent canal closure and pump stations to reduce the risk posed by hurricane storm surges at the mouth of Lake Pontchartrain.
