Solar Securitization and the Solar Access to Public Capital (SAPC) Working Group

Background & SAPC Presentations

NREL's Solar Access to Public Capital (SAPC) working group was designed to open capital market investment for solar assets via securitization and other financial innovations. SAPC was a three-year initiative that ended in September 2015. SAPC membership included over 440 organizations such as top residential and commercial solar developers, law firms, investment banks and capital managers, rating agencies, independent engineers, and other key stakeholders in the solar finance space.

SAPC encompassed numerous initiatives, described below, to build consistency and quality in the asset class, provide investors the data and other tools necessary to minimize due diligence cost and time, and ease a pathway to securitization and other investment mechanisms across the solar development community.

SAPC Standard Contracts

The following documents were designed to improve consumer transparency, reduce transaction costs in the solar asset contracting process, and facilitate the pooling of the associated cash flows so that they may be securitized and sold in the capital markets.

Residential Contracts

Commercial Contracts

Best Practices of Installation and Operation and Maintenance (O&M)

Several SAPC subcommittees were dedicated to asset quality to improve investor confidence assets are well built and well maintained. Installation Best Practices (referred to as Quality Assurance Protocols) were developed by a subcommittee focused in this area, see below. O&M Best Practices and an O&M cost model were developed by a relevant subcommittee on that task.

oSPARC Performance Data

The Open Solar Performance and Reliability Clearinghouse (oSPARC) database is available for pubic evaluation and data contribution. The database was developed by the SunSpec Alliance in collaboration with NREL and the SAPC process.

Mock Filings with Rating Agencies

SAPC members developed two mock filings to foster dialogue with the rating agencies and the solar community: one for a pool of residential leases and another for a pool of commercial PPAs. The SAPC Legal subcommittee developed the following mock securitization term sheets (i.e., legal descriptions of the securitization structure, managing entities, and cashflow waterfall) to facilitate comprehension of solar securitization and potentially reduce transaction costs for new securitizations to reach the market. The SAPC commercial term sheet includes a novel approach to raising debt by promoting a "tandem" structure that includes both tax equity and securitization debt in the initial capital stack.

The tandem structure is available here. The residential term sheet will be available soon.
