PPA de-risks your energy strategy
and protects your balance sheet
We cover 100% of the upfront costs. Conserve your cash and avoid adding debt to your balance sheet.
Lock in an electricity rate significantly below your current utility price from day 1.
A fixed-price contract for 10-20 years protects you from future price shocks and provides unparalleled budget predictability.
We provide continuous monitoring, preventative maintenance, and repairs. Your asset is always performing at its peak.
Our returns depend on the system’s output, so we are fully invested in its success. We use top-tier equipment and certified installers.
We bear the technology and operational risks. If the system underproduces or equipment fails, it’s our problem, not yours.
