Natural Gas Power Solutions for Your Industry

Flexible natural gas gensets have gained popularity across industries due to their low total cost of ownership, reliable continuous power support, and effectiveness as emergency backup solutions. Here are examples of industries Cat Electric Power serves.

MUNICPAL UTILITIES

Strengthen grid resilience with assets designed for continuous operation and rapid dispatch during peak demand.

MANUFACTURING

Reduce operational expenses with CHP solutions that utilize waste heat to lower utility bills and improve overall facility efficiency.

HEALTHCARE

Get reliable backup power and generate demand-response revenue with Cat natural gas gensets for hospitals and healthcare facilities.

LANDFILL & WASTE MANAGEMENT

Capture your landfill’s methane and turn it into a valuable energy source that can lower long-term costs and reduce emissions.

DATA CENTERS

Protect the rapidly growing amount of data in your facility with 24/7 continuous power that’s quiet and fuel efficient.

WASTE WATER TREATMENT

Lower your community’s treatment costs with a biogas solution. Convert leftover sludge to energy with an efficient natural gas genset.

Determine Your Fuel Choice: Natural Gas vs. Diesel

If you need a power solution but still aren’t sure if gas is the right choice for you, view our quick and simple comparison below.

of

Natural Gas

Lower emissions: Natural gas fuels generally produce lower NOx, sulphur dioxide, and CO₂ than diesel.
Long-term savings: There are typically lower average fuels costs with gas products, lowering your total cost of ownership.
Fuel versatility: Many Cat^® generator sets can be configured to use propane, natural gas blended with hydrogen, and other low-emission fuels. Facilities which produce organic waste can even route the gases to their generator sets as fuel for even greater savings.
Savings from CHP: With combined heat and power (CHP), excess heat from natural gas generators can be safely captured and used for building heating or to heat water, thereby saving energy.

of

Diesel

Lower initial investment: Typically, diesel generator sets require lower up-front investment.
Small and powerful: Diesel power solutions generally accept transient loads better than gas products, especially with larger load steps.
Mobile products: There is a wider range of diesel mobile products available for easy transporting and fast installation.

Support Demand Response

What is demand response?

Demand response programs are a way for energy utility providers to stabilize the grid when energy demand soars. These programs encourage energy users to reduce or shift their power usage during peak consumption times to protect against blackouts and rising prices.

How can your business Benefit?

Our natural gas gensets can help large commercial and industrial energy users access new revenue. Get compensated for the excess power your gas genset produces when participating in a demand response program and exporting excess power to the grid.

Why is demand response important?

As the threat of power outages increases, demand response participants can reduce demand on the utility supply, especially in the event of a grid emergency. Demand response programs combined with natural gas gensets can meet your business’ needs while helping your community have reliable power.

Biogas and Combined Heat and Power

These enhancements are compatible with natural gas gensets and can take your power solution to the next level of efficiency.

BIOGAS

Transform organic waste to energy. Power a natural gas genset with biogas to reduce greenhouse gas emissions, eliminate odor issues – and amplify long-term savings.

COMBINED HEAT AND POWER (CHP)

Maximize the benefits of biogas with CHP. Use waste heat from your natural gas genset to produce thermal energy for heating, cooling, hot water, and industrial processes.

Power Through Outages

Deliver dependable backup power with industry-leading Cat natural gas standby generators. Be prepared for long outages or when diesel fuel isn’t available. Our standby gas generators are designed for rapid response to run without interruption thanks to longer maintenance intervals.
