Business Editors

DENVER & WYOMISSING, Pa.--(BUSINESS WIRE)--April 4, 2001

Metretek Inc., a Florida-based subsidiary of Metretek Technologies Inc. (Nasdaq:MTEK), and UGI Energy Services Inc., a subsidiary of UGI Corp. (NYSE:UGI), today announced an agreement to test-market Metretek Inc.'s PowerSpring(TM) Internet-based energy management software with customers of GASMARK, a $300 million (sales) business unit of UGI Energy Services that assists consumers in the purchase and transportation of energy.

Metretek Inc. ("Metretek Florida") is one of the leading suppliers of automatic meter reading ("AMR") equipment in the country. UGI Energy Services is a supplier of energy to commercial and industrial customers.

The pilot program, scheduled to last a year, is designed to obtain feedback from energy purchasers regarding the commercial application of PowerSpring's energy management system.

With PowerSpring's user-friendly Internet-based software solution, an energy buyer's purchasing decisions are enhanced with access to near-real-time energy consumption information. AMR devices for the program are designed and manufactured by Metretek Florida.

According to Carl Myers, vice president and general manager of UGI Energy Services, the PowerSpring technology will enable GASMARK as an energy provider to monitor its larger customers' usage for more accurate balancing and scheduling information.

"Moreover," said Myers, "it will clearly be of value to our customers if, especially given the current volatility of the energy markets, we can provide them with the tools to make better energy purchasing decisions. We believe this is an area where -- in facilitating the rapid and timely communication of information -- the flexibility and power of the Internet can greatly benefit both GASMARK and its customers."

In addition to energy consumption information, said Ron McKee, president of Metretek Florida, PowerSpring offers graphing capabilities and other data such as historical and forecasted weather information by specific location, NYMEX exchange information, A.G.A gas storage data and relevant energy news.

"We believe this is an excellent product that will quickly demonstrate its value to consumers and suppliers alike. We are delighted to initiate this pilot program with a partner of GASMARK's experience," said McKee, "and we are optimistic that its success will warrant its expansion into an ongoing service option for all GASMARK customers."

Metretek Technologies Inc. through its subsidiaries -- Metretek Inc. ("Metretek Florida"); Southern Flow Cos. Inc.; and PowerSecure Inc. -- is a diversified provider of energy measurement products, services and data management systems to industrial and commercial users and suppliers of natural gas and electricity.
