Stem and CPower Announce Energy Management Partnership

Demand response, intelligent energy storage leaders to jointly offer
integrated demand-side solutions

MILLBRAE, Calif. & BALTIMORE–(BUSINESS WIRE)–Stem,
Inc., the leader in intelligent energy storage services, and CPower,
the leader in demand response (DR) and demand-side energy management
services for commercial and industrial customers, announce a new
partnership to deliver a unique demand-side energy solution to customers
across the U.S., starting in California.

The partnership will combine Stem’s energy storage services with
CPower’s demand response and curtailment services to offer customers an
integrated solution for managing electricity demand. In so doing, Stem
and CPower co-optimize two increasingly important resources at the
customer facility level to provide customers with both a steady revenue
stream and substantial energy savings, all while alleviating stress on
the grid.

The Stem-CPower partnership is ideal for commercial, industrial, and
institutional customers who are interested in optimizing operations,
increasing profitability, and advancing sustainability. Customers can
now take advantage of the confluence of energy management technologies
and smart grid opportunities by automatically reducing load when prices
peak, earning revenue through DR, and supporting a modern, resilient
grid for their community.

“Stem’s wide and deep experience with intelligent energy storage
solutions enables substantial savings opportunities and more delivered
value for our customers,” said John Horton, CPower’s President and CEO.
“As peak demand charges rise and time-based rates become more complex,
customers are looking for expert advice on how to automate energy
curtailment and reduce costs. This unique partnership creates a
comprehensive demand management solution that is easier and more
valuable for customers, defending against high electricity prices and
paying for demand flexibility in tandem.”

Stem and CPower’s collaboration benefits the grid by reducing the demand
for electricity when the grid is stressed, when electricity prices are
volatile, and when less-flexible generation assets can not immediately
respond. Through Stem-CPower partnership, utilities are able to dispatch
fast-acting, highly-reliable virtual power plants that combine and
coordinate stored energy and load flexibility for maximum impact. Both
companies are proven execution leaders of dynamic, digitally-driven
aggregation networks, serving major utilities with modular capacity and
resources to be instantly applied to address any locational issue, for
example in the CAISO markets.

“We’re excited to offer our customers more options for demand response
participation. CPower’s unparalleled DR expertise and industry-leading
technology platform will deliver increased revenue opportunities for our
customers,” said John Carrington, CEO of Stem. “Stem and CPower can
maximize a customer’s ‘save and earn’ abilities, allowing customers to
maximize their savings from peak demand management, while also
maximizing their earnings from flexible, controllable loads.”
