Cummins and NRG Launch Major Technology Platform to Reduce Energy Costs for Large Businesses

—New Solution Simplifies Customer Integration to Deliver Reliable,
Cleaner Energy and Reduce Stress on Grid—

COLUMBUS, Ind. & PRINCETON, N.J.–(BUSINESS WIRE)–#BackupGeneration–Today Cummins Inc. (NYSE: CMI) and NRG Energy, Inc. (NYSE: NRG)
announced a strategic partnership to deploy a resilient, cleaner and
cost-effective distributed energy platform for commercial and industrial
customers. This easy-to-implement solution provides customers an
opportunity to transition to a smarter energy consumption model. The
platform, with a preliminary estimated hundreds of megawatts capacity or
enough to power tens of thousands of homes, enhances a customer’s energy
usage through Cummins-powered generators and NRG distributed energy
resource capabilities.

The companies see the solution potentially saving customers up to 15
percent over their current energy costs, often at no enrollment expense.
Beyond giving customers more control over their energy future, the
platform is expected to significantly reduce environmental impact and
grid stress. The platform architecture allows for more capacity to meet
expanding market needs.

While the formal partnership is new, the companies have successfully
implemented distributed energy models for several customers over recent
years and are now ready to bring this proven, cost-effective solution to
more customers throughout the northeast United States.

“Reliable power remains critical in the overall distributed energy
equation, and this model leverages Cummins’ expertise in making power
generation equipment for the most harsh and demanding of operating
conditions,” said Norbert Nusterer, President – Power Systems Business,
Cummins Inc. “Having deployed several hundred megawatts and delivered
strong economic returns and reliability to customers, this partnership
is intended to expand on the experience we have gained. Our partnership
with NRG brings together nearly 125 years of energy leadership to give
more customers new ways to achieve their goals in environmental
stewardship and cost and risk reduction.”

“Cummins and NRG have a shared vision to use new technologies, like this
platform, to provide customers with reliable power and help navigate the
increasingly complex energy market,” said Robert Gaudette, President of
NRG Business Solutions. “This is just one example of how we can continue
to optimize new and existing energy technologies so customers can use
less, and pay less, for electricity. The power producer of tomorrow will
do more than just move electrons; it will direct them where needed most
– with measurable benefits for the customer, the grid and the
environment.”

Cummins and NRG will form a joint development team to pursue solution
sales, and market and maintain energy assets to guarantee outcomes for
end-use customers.
