Commercial Property Assessed Clean Energy (C-PACE)

What is C-PACE?
Commercial Property Assessed Clean Energy (C-PACE) is a financing mechanism designed to encourage energy and water efficiency improvements, renewable energy systems, and building resiliency projects for commercial properties. As a voluntary, open-market financing model, C-PACE allows commercial property owners to secure private low-interest, long-term loans for eligible energy improvements whereby the loan is placed on the property as an assessment and is repaid through the county property tax system. The financing arrangement then remains with the property even if it is sold, facilitating long-term investments in building performance. The longer-term payback allows the efficiency improvements to pay for themselves over time.

Around the country, C-PACE financing has been used for HVAC upgrades, boilers, chillers and furnaces, automated building controls, high efficiency lighting, building envelopes (insulation, windows, etc.), low-flow fixtures, solar, geothermal, electric vehicle charging stations, and other energy improvement projects. Oklahoma’s C-PACE project eligibility and other program guidelines are currently being developed. Program completion and launch in Tulsa County is expected no later than Fall 2020.

C-PACE encourages economic development through private investment in smart energy solutions for Oklahoma’s commercial buildings..

How is C-PACE Different?
Unlike traditional loans for building improvements, C-PACE can provide up to 100% financing for program-eligible improvements. C-PACE loans are tied to the building’s county property tax record as an assessment and repaid as an additional line item on the property tax bill. No down payment is required nor is the property owner required to give a personal guarantee on the loan. The lenders enter into loan contracts directly with the property owners and the county bills the annual payment on the property tax statement and remits that payment to the original lender. If the property is sold, any remaining assessment can be passed to the new property owner.

C-PACE in Oklahoma
Oklahoma’s C-PACE enabling legislation was effective November 1, 2019.  To create an active program, counties must pass resolutions authorizing C-PACE voluntary special assessment liens and establish the program.  Tulsa County became the first in Oklahoma to pass a resolution in September 2019 expressing intent to implement C-PACE.  INCOG is working with the county and other partners throughout the state to create a C-PACE Program Administrative Platform template that will work statewide for any county choosing to initiate a program.  Consistency in policies, procedures and guidelines throughout Oklahoma assures streamlined processes for counties and program participants. The intent is to have C-PACE active in 2020.
