Energy Efficiency Project Planning Resources

Start planning your next project and take advantage of some of our highest incentives ever.

Energy efficiency is a good investment, but where do you start? With a wide range of energy-efficient technologies and energy-saving opportunities available to businesses today, determining which projects to pursue is often the biggest challenge. Potential savings and project payback may vary based on factors such as type of facility, hours of operation, and age of equipment — among others. That's why we've pulled together the resources below to help you select, prioritize, and plan your projects so you can benefit from increased incentive levels in the upcoming program year.
