Standardized PPA is the key to solar structured deals

John Joshi believes we all need to take charge of our energy future and developing a robust SPPA (standardized power purchase agreement) market if we are to ramp up adoption of solar energy by consumers and commercial customers. In this piece, he explains why.
Standardized PPA is the key to solar structured deals

In a previous article, I wrote about the developments with Bank of America, Prologis and NRG Energy and the DOE loan guarantee for a portfolio of distributed solar projects in the US. I observed that the framework that these firms had developed along with the DOE program could be a harbinger for a solar securitization market. I noted that for the market for solar structured transactions to grow within a capital markets approach, it would require standardization of solar power purchase agreements and lease contracts. In this article I will explore a standardized PPA in more detail.

A solar PPA is an agreement between a developer/investor of solar energy and a customer/off-taker to purchase the solar power at an agreed upon price in a long-term contract. The developer/investor installs, maintains and retains ownership of the solar facility on a customer facility – be it a rooftop or other property. The customer pays only for the power generated by the facility and not for the cost of the equipment and installation costs. On-going operation and maintenance is also the responsibility of the developer / investor. A solar PPA agreement reduces the risk and cost for the customer by eliminating out of pocket capital expenditure. The agreement also locks in energy costs for 15 to 25 years, thereby reducing energy cost volatility for the off-taker.

The basics of a solar PPA cover:

Financing / Management

- Developer / Investor secures financing for the project

- Sells electricity at the contract price for the term of the contract

- Construction of Construction / Modification of Design

- Warranty / Insurance / Sales Tax / Income Tax / Property Tax

- Contractor Responsibility and Status Reports

Regulation / Regulatory Issues

- Conforming to State and local codes

- Permitting / Liens and Easement Rights

- Hazardous Materials

Contract Timeline

- PPA term (5 to 25 years) and contract price

- Escalation clause if any

- Location of Facility

- Extensions / Early Purchase Option / Residual / Salvage Value

- End of Term Purchase Option / Transfer of Ownership

Operation and Metering

- Grid Connection and Initial Period / Operation Period

- Site Access Rights and Security

- Standards for Operations and System Shut Down / Decommissioning

- Billing / Invoice Delivery / Payment / Dispute Resolution

- Net Metering & Utility Credits and Interconnection

Sales of Electricity

- Metering and Delivery of Electricity / Limits on Obligation to Deliver

- Remote Monitoring / Meter Testing

- Solar Incentive Programs / Ownership of Tax Attributes

The above outlines some of the key issues, though not by any means comprehensive, covering a solar PPA. Standardized PPA contracts for the solar and renewable energy sources will reduce costs for investors / developers and off-takers and allow for more efficient analysis by the rating agencies and capital market investors.

Capital Markets stake holders – investors, deal arrangers and rating agencies prefer to have standard well defined structures that can be replicated and can be assessed using standardized risk assessment metrics. Standardization allows for economies of cost and allows for the development of standard models which can be used to develop a rating and risk criteria by all stakeholders.

Third-party models and analytics can provide access to robust models for analysis, thereby increasing the number of investors who can participate in transactions. Liquidity is a key need of investors and deal arrangers so that a robust market for a new asset class can be developed.

As I noted in previous articles, a liquid, transparent and standardized process for solar PPA securitization will benefit all stakeholders by providing transparency, broader appeal to investors, lower cost and wider access to capital, resulting in broader adoption of solar energy by consumers and commercial customers.

What are the next steps for a standardized SPPA? A consortium of stakeholders and industry associations have to work together to develop something that is workable. This would include representation from investor groups, deal arrangers, rating agencies, law firms, EPC firms, manufactures and regulators to develop the standards for adoption by the industry.

We all need to take charge of our energy future and developing a robust SPPA market is an important step towards achieving that goal. Please feel free to contact me and offer your comments on this important issue.
