Custom Commercial Rebates - Business


Arizona businesses, you may be eligible for valuable rebates when you take measures to reduce your natural gas consumption.

Measures that target cost-effective natural gas savings, including retrofits, improvements and first time installations, that exceed current applicable codes and standards, may qualify. We don’t define any specific measure in our program to give your business the highest flexibility on making improvements that make the most sense for your business.

Participants may propose any measure that:
  • Produces a verifiable natural gas usage reduction
  • Is installed in either existing or new construction applications
  • Has a minimum useful life of seven years
  • Exceeds Southwest Gas’ minimum cost-effectiveness requirements
Measures that are excluded from this Program include those that:
  • Are offered through the Smarter Greener Better Commercial Rebates program
  • Rely solely on changes in customer behavior
  • Merely terminate existing processes, facilities, or operations
  • Are not fuel neutral
  • Are required by state or federal law, building or other codes, or standard industry practice
  • Qualify for rebates through any other program offered by Southwest Gas
