NATIONAL GRID ACHIEVES SUCCESSFUL WINTER PEAKING PROJECT IN NORTHEAST WITH SUPPORT FROM NG ADVANTAGE

Frigid Temperatures and Winter Storms Sparked Demand Across Northeast − NG Advantage Provided Safe and Reliable CNG Service in New York

COLCHESTER, VT – NG Advantage, the pioneer in virtual pipeline CNG service, which is majority-owned by Clean Energy Fuels (NASDAQ:CLNE), successfully served National Grid with a three-month winter peaking project at a facility in New York State. During this winter’s extremely low temperatures, NG Advantage offered the utility a CNG solution capable of delivering 15,000 Mcf a day to support spikes in demand and ensure reliable heat for New York residents.

“Based on the limited availability of natural gas supplies in the Northeast, National Grid determined that for this past winter, working with a virtual pipeline energy company was a necessary short-term fix to help meet the energy needs of our customers through the use of this non-pipeline solution,” said John Vaughn, Vice President of Energy Procurement at National Grid. “NG Advantage demonstrated a strong commitment to safety and was poised to provide the relief for winter peaks when we needed it.”

Every cold snap requires additional energy to meet increasing demand. This is especially challenging given the constrained natural gas infrastructure in the Northeast. To prepare for winter months, National Grid was looking for temporary compressed natural gas injection services for relief during winter peaking times.

“As the temperatures dropped and customer demand for natural gas increased, National Grid turned to NG Advantage to help supplement their supply,” said NG Advantage CEO Rico Biasetti. “With our tremendous record on reliability, safety, and compliance, this utility knew they could count on NG Advantage to deliver. As we continue to grow throughout the Northeast, we will look to expand these and other relationships with utilities and power generators to ensure service reliability to their customers during the most adverse weather conditions.”
