HOUSTON – February 10, 2015 – Think Energy, the retail electricity provider established by GDF SUEZ Energy
Resources NA to serve residential and small commercial customers, announced the launch of residential service in
Massachusetts, a significant step in the company’s strategic growth efforts.

focus on delivering competitive fixed-price plans that allow customers to budget with more confidence.

“At GDF SUEZ Energy Resources, we have a strong commitment to transparency that’s woven into the fabric of
every aspect of our business – from our service offerings for large commercial and industrial customers to the plans
we deliver small commercial and residential consumers through the Think Energy brand,” said Henry. “Being open
and truthful about costs helps keep the ‘unknowns’ to an absolute minimum, and our customers appreciate that.”

John Henderson, senior vice president of retail markets at GDF SUEZ Energy Resources, who leads Think Energy,
added that the company’s financial strength and stability have also been key factors behind the recent growth.

and tomorrow,” explained Henderson. “In the end, we understand that users want the certainty of competitive
pricing with the comfort of knowing we will honor our commitments. That’s what we work to deliver every day, and
