Across the United States, developers and hosts/customers are using power purchase agreements (PPAs) to finance solar energy projects. In fact, PPAs have been a big contributor to the staggering growth of the solar sector over the past decade. As the demand for solar energy generation has skyrocketed in recent years, the financing mechanisms used in the development of solar PV projects have also diversified. A PPA is one such mechanism used in solar project financing and development.



What is a Power Purchase Agreement?

A power purchase agreement is a buying structure for purchasing renewable energy. A PPA is a straightforward, effective way for organizations to procure renewable energy in large quantities. As the name implies, a PPA involves an agreement between the concerned parties, the solar developer and the consumer/host, wherein the developer takes care of the entire solar panel installation process on the host’s property, from beginning to end. The PV system installation comes at little or no cost to the consumer/host, who is essentially purchasing the services of the solar system as opposed to the system itself.



There are a number of different types of PPA, from physical PPAs to sleeved PPAs and virtual PPAs, all of which can be used to deliver renewable energy in sufficient quantities to meet sustainable energy requirements or commitments. For a more in-depth explanation of power purchase agreements and how they work, please consult our article:

What are the Different Types of Power Purchase Agreement?

As noted, there are a number of different PPAs, with physical PPAs and virtual PPAs making up the bulk of transaction mechanisms in the sector, alongside sleeved PPAs which are an increasingly popular approach.



  • Physical Power Purchase Agreement

  • Virtual Power Purchase Agreement

  • Sleeved Power Purchase Agreement

What are the Benefits of a Solar Power Purchase Agreement?

By removing many of the barriers commonly associated with the outright purchase of a solar PV system, a solar power purchase agreement makes the process of going solar simpler and more affordable for many people. Some of the key benefits of a PPA include:



  • No Upfront Costs/Minimal Upfront Costs: A solar PPA offers an immediate benefit to the host/customer. The developer handles financing, procurement, and installation—the host/customer simply goes solar and begins saving on their utility bill as soon as the system is operational.

  • Low Risk: With a PPA, the developer is solely responsible for all PV system performance and maintenance, taking on any risk and relieving the customer/host of any responsibility.

  • Cheap Energy: Typically, there are two pricing plans available with a solar PPA, a fixed escalator plan or a fixed rate plan, both of which lead to savings for the customer/host. 

  • Increased Property Value: It’s been shown that a solar panel installation, as a long-term, transferable project, contributes to increased property values. If the customer/host decided to sell their property, they would see the benefit of this value increase, without even owning the panels themselves.

  • Tax Credit Leverage: As solar developers are capable of utilizing tax credits to reduce the overall cost of a PV system—more so than a typical solar customer—a solar power purchase agreement allows for optimal leveraging of available tax credits.

Power Purchase Agreements: State by State

Most states have statutes which refer to PPAs, or offer a definition, and fifteen states have enacted legislation to authorize and regulate power purchase agreements. Below, we’ve outlined PPA statutes for the fifteen states in question.



Arkansas

Ark. Stat. Ann. §23-18-108 (House Bill 1633, 2015)

Utilities are authorized to enter into PPAs. However, utilities are prohibited from entering into PPAs longer than five years, or recovering PPA costs via rates unless the commission finds that:



  1. The cost is reasonable.

  2. The agreement provides savings for retail customers.

  3. It’s required by public necessity.

  4. It’s necessary to ensure incremental supply to rectify shortage.



Colorado

Colo. Rev. Stat. §40-2-123

A utility, with commission approval, may enter into a PPA with the owner of an ‘integrated gasification combined cycle’ (IGCC). Public utility costs associated with the PPA may be recovered through a rate adjustment clause.



Connecticut

Conn. Gen. Stat. Ann. §16a-3f

The commissioner of Energy and Environmental Protection has authority to solicit proposals from renewable energy sources. If the proposals are found to be in the interest of ratepayers, they may be selected to meet up to 4% of the state’s load distribution. The commissioner also has the authority to direct electric distribution companies to enter into PPAs for terms below 20 years. PPAs must be approved by the Public Utilities Regulatory Authority and costs incurred by the distribution companies may be recovered through electric rates for customers.



Delaware

Del. Code Ann. tit. 29, §8057(d)(1)(a)

Cash grants from Delaware’s ‘Green Energy Fund’ may be paid to customers who have entered into a PPA for renewable energy technology, and have placed the technology into service.



Hawaii

Hawaii Rev. Stat. §269-16.22

Electric utility companies are allowed to recover all costs arising as a result of a power purchase agreement. Recovery comes through customers via one or more surcharges established by the public utilities commission.



Iowa

Iowa Code Ann. §476.6A

Owners of ‘alternative energy production facilities’ who have not entered into a PPA with a public utility, and will be/are attached to electric transmission/distribution lines, must give notice to the public utility prior to construction or alteration.



Michigan

Mich. Comp. Laws Ann. §460.60

Public utilities with more than 500,000 customers in the state are required to enter into PPAs for the purchase of capacity & energy from resource recovery facilities that incinerate qualified landfill gas, solid waste scrap tires. However, this statute does not apply after 120 MW of capacity in a utility service territory have been contracted OR more than 30 MW of scrap tire fueled capacity has been contracted and is in commercial operation. 



Mich. Comp. Laws Ann. §460.6s

Any electric utility proposing a PPA for a period of six years or longer must apply to the commission to seek a certificate of necessity that:



  1. The terms of the PPA represent the most reasonable, prudent means of meeting that power need.

OR

  1. The price specified in the PPA will be recovered via rates from the utility’s customers.



The application must be granted by the commission if the following criteria are satisfied:



  1. The utility has demonstrated a need for the power that would be supplied.

  2. Information shows that the utility will comply with all state & federal environmental standards.

  3. The price of power in the PPA is reasonable, and the result of competitive solicitation.

  4. The PPA represents the most reasonable means of meeting power needs.



Once the PPA is used, the commission should include all reasonable costs for which a certificate of necessity has been issued in the utility’s retail rates. Where a certificate of necessity has been granted, the commission cannot bar the recovery of the PPA costs. The utility must also file annual reports to the commission regarding the status of the PPA, including details of costs and project scheduling.



Montana

Mont. Code Ann. §69-8-419

The commission must adopt rules that establish minimum filing requirements and standards for evaluating the reasonableness of power purchase agreements.



Mont. Code Ann. §69-8-421

A 180-day deadline is established for the commission to rule on applications for approval of a PPA from an existing generation source. A 270-day deadline is established for the commission to rule on applications for approval of a PPA that would result in new electricity generating resources. The commission also has the authority to inquire into a public utility’s management of a PPA, and to disallow rate recovery for costs arising as a result of the utility’s failure to reasonably manage electricity resources in accordance with statutes and commission rules.



Nebraska

Neb. Rev. Stat. § 70-1904

C-BED project developers and electric suppliers are authorized to negotiate mutually agreeable PPA terms. C-BED projects operating under a PPA are not eligible for any net energy billing. 



New Hampshire

N.H. Rev. Stat. Ann. §362-A:4-c

The commission is mandated to independently, expeditiously consider all power purchase agreements regardless of the status of any other such pending renegotiations.



New Jersey

N.J. Stat. Ann. §48:3-61

Electric public utilities are permitted to recover stranded costs related to long-term and short-term PPAs with other utility companies and nonutility generators through ‘market transition charges’ to customers. Additionally, the Board is authorized to approve the ‘buyout or buydown’ of PPAs with nonutility generators, or new PPAs that result from renegotiation, restructuring, or termination of previous power purchase plans, if the Board determines that this will result in the reduction of a utility’s stranded costs.



Oregon

Or. Rev. Stat. §758.525

Electric utilities must offer to purchase energy or capacity from ‘cogeneration facilities or small power production facilities’. The price for a purchase cannot be below the utility’s avoided costs.



Rhode Island

R.I. Gen. Laws §39-26.6-11

Electric distribution companies are not required to enter into PPAs for the procurement of the state’s renewable energy distributed-generation capacity requirements under the RI ‘Renewable Energy Growth Program’. 



Virginia

Va. Code §56-594

Upon written request from a ‘customer-generator’, their electric supplier shall enter into a PPA consistent with the minimum contract requirements established by the commission. The PPA must obligate the supplier to purchase excess electricity at the rate provided for in a net metering standard contract/tariff approved by the commission. When entering into a PPA, the statute gives the ‘customer-generator’ a one-time option to sell any renewable energy certificates (RECs) to the supplier at an amount established by the commission. 



If the supplier in question has an RPS plan approved by the commission, all costs incurred by the supplier to purchase excess electricity and RECs are recoverable through its Renewable Energy Portfolio Standard rate adjustment clause. If not, all costs are recoverable through the supplier’s fuel adjustment clause. Suppliers are obligated to enter into power purchase agreements until the rated generating capacity owned and operated by ‘customer-generators’ reaches 1% of each electric distribution company’s adjusted Virginia peak-load forecast for the prior year. 



Washington

Wash. Rev. Code §80.04.570

PPAs for ‘coal transit power’ must be approved by the commission in an adjudicative procedure. All PPAs must allow for modification in the event of new/revised emissions performance standards from state or federal law. The commission may only approve if the terms provide adequate protection to ratepayers and the electrical company, if the resource is needed to serve ratepayers, and if the resource is cost-effective. A mechanism has also been established to set recovery costs in rate setting. 



Wash. Rev. Code §80.80.060

Electrical companies are not permitted to enter into a long-term financial commitment unless base load electrical generation under the commitment complies with greenhouse gas (GHG) performance standards. The commission will make a decision regarding any prospective power purchase agreement based on GHG emissions standards. The commission cannot decide based on actual cost, or recovery of costs.
