An Act providing for energy efficiency and conservation plans with inclusion of mechanical insulation.

SB 758, the "Mechanical Insulation Act," prevents Pennsylvania's Public Utility Commission from rejecting energy efficiency plans submitted by electric distribution companies solely because they include mechanical insulation. The bill requires that such insulation be proven cost-effective using a specific "total resource cost test" approved by the Commission. This directly affects electric companies developing energy conservation plans and the Commission's review process. The law takes effect 60 days after enactment.
