GLASGOW, UK -- (MARKET WIRE) -- May 12, 2005 --

ScottishPower's PPM subsidiary announces gas storage expansion in the US

ScottishPower's US competitive energy subsidiary, PPM Energy (PPM), today announced the expansion of a gas storage development project in west Texas and the acquisition of a New Mexico gas storage facility. The combined investment is expected to be approximately $120 million and to achieve returns of at least 300 basis points above PPM's weighted average cost of capital.

Expansion of the proposed Waha facility in west Texas from 7.2 billion cubic feet (BCF) to 9.5 BCF is a result of favourable geologic testing of the salt cavern site and strong market demand. Waha is expected to be built in two phases and begin operations by December 2007.

PPM also acquired the 4.5 BCF Grama Ridge facility in southeastern New Mexico from ConocoPhillips of Houston, Texas. PPM plans to expand the Grama Ridge reservoir facility, which has operated since the early 1970s, to 6.0 BCF. Both Waha and Grama Ridge are connected to multiple pipelines in the area.

PPM has announced its intention to triple owned gas storage capacity from present levels to approximately 125 BCF by 2010.
