Renter / Low Income Focus

Overcoming the Barriers

Increase incentives and/or financing options to encourage landlord and low income customer conversions

Municipal & State Facilities Focus

Develop programs for municipal customers to purchase equipment to convert to natural gas. Municipal & state facilities can act as anchor customers for broader expansion.

Build on Existing Energy Efficiency

Leverage existing energy efficiency programs to more aggressively grow natural gas access and defray inside the home conversion costs (i.e., provide higher incentives for high efficiency gas heating installations).
