Corporate Social Responsibility (“CSR”) has been a hot topic for the past few years, with numerous Fortune 500 companies announcing aggressive goals relating to their clean energy usage. To many of these companies, transitioning their energy usage into renewable energy sources plays an integral part in their sustainability goals. Offsetting energy costs through increased use of renewables is not only cost-effective, but such practices allow  for CSR success which has a profound impact on consumers.

Companies have acknowledged that to stay competitive in the market and to increase consumer trust, they must look to what consumers value in a brand. According to a 2015 study conducted by Cone Communication/Ebiquity, “91% of global consumers expect companies to do more than make a profit,” such as “operate responsibly to address social and environmental issues.” The study notes that companies that support social and environmental issues maintain large numbers of consumers that perceive said companies in a positive light (93%), self-identify as loyal to the company (88%), and generally trust the company and its purposes (90%). These are powerful means to grow and solidify a brand, and generate goodwill among consumers.

While the rapid expansion into renewables as a means of CSR can be easily explained by the positive tangible benefits it brings to local communities (like clean air and water), it also doesn’t hurt that often times wind and solar energy represents a cost savings to the business by avoiding more expensive utility-fed power. This is without accounting for the environmental costs savings, such as carbon abatement and water cleanup, which generally occur with greater renewable use. With companies such as Amazon, MGM, Apple, and Salesforce all announcing aggressive sustainability and renewable energy goals, we’re seeing a growing shift away from private sector fossil fuel usage as CSR goals are increasingly prioritized.

Last month, Salesforce made headlines for achieving its net-zero carbon emissions’ goal decades before the goal date of 2050. For years, Salesforce has worked on increasing the energy efficiency of its infrastructure, servers, and buildings to help it obtain the net-zero emissions title. The company was finally able to complete this task by purchasing power through various wind farms in Texas and West Virginia. Salesforce is now striving for a 100% renewable energy goal globally. While they’re headed in the right direction, this will surely prove a greater challenge (and reward) for the cloud-based software company.

Asics, the popular footwear company, announced this week they were expanding upon their sustainability goals by installing a 1MW solar system at its primary distribution center in Mississippi. This system will be the largest privately-owned solar array in the state, and will power 20% of the energy usage at the location.

MGM Resorts International now boasts the largest rooftop array in the United States, with 8.3 MW spanning over 23 acres atop its Mandalay Bay location. At full production, the system will account for 25% of the hotels total energy usage. Not only did the resort install the largest rooftop system, it also paid 87 million dollars to stop purchasing electricity from NV Power, a cost they believe will be recouped within 7 years.

While many companies have reaped the economic benefits of “going green,” a rare few have had the misfortune of their sustainability efforts being scapegoated by critics for plummeting stock prices.  NRG is a well-known example of this. David Crane, the former CEO, had high hopes of transforming the company, only to be fired before his vision could be fully implemented. The company claims it will continue to invest in renewable energy, but will stay away from emerging technologies.  However, for each cautionary tale, there are many more successful ones of transitions into renewable energies.

In the end, these companies are achieving their sustainability goals in large part due to solar power. This can largely be attributed to solar being one of the cheapest and easiest forms of renewable energy available. A 200kW solar array can offset carbon emissions by roughly 250 tons per year:  the equivalent of taking 47 passenger vehicles off the road for one year, or not burning 120 tons of coal. While these figures may seem like a drop in a very large bucket, the reality is every positive action taken, whether it be installing solar or increasing energy efficiency, leads us to a more sustainable, energy secure future that does not rely on carbon–emitting fossil fuels to power our companies and economy.

The asset-backed securities (ABS) market has provided a viable means of financing to several asset classes for decades.  In the solar industry, residential players like Solar City, Sunnova, Mosaic, Spruce, and Sunrun have utilized the ABS market for several years.

Residential securitizations have exceeded $500mm thus far this year, highlighted by Sunnova’s  debut securitization, with several additional financings rumored to be on the horizon for the residential market.

With year-over-year solar market growth exceeding 90% in 2016, the apparent demise of YieldCos, and new institutional capital entering the solar market, it’s likely we will see solar securitization growth in 2017 and beyond. Yet, aside from a few whispers, the C&I market has been absent from a presence in ABS.

Why is C&I late to the game?

Looking at the published assigned ratings from Kroll for each of the residential solar and efficiency financings, and the criteria established by Kroll’s General Rating Methodology for ABS, it was clear that a few boxes need to be checked when looking to the ABS markets:

  1. Volume & Historical Performance
  2. Standardized transaction documentation
  3. Investment Grade off-taker credit rating – utilizing an industry accepted rating scale

Other criteria is certainly considered (resume of sponsor, technology, etc.), however, when comparing residential to C&I based on this criteria, one can see why C&I falls short.

Volume & Historical Performance

The maturity of the residential asset class has led to several large players and billions of tax equity dollars dedicated to a programmatic financing approach, and a high volume of cash-flowing assets, to-date. Relatively higher residential utility rates have allowed for a larger national geographic footprint compared to C&I, providing a long runway for the asset class to mature. Nearly a decade in which developers, investors and energy companies have thrown resources at the industry and fine-tuned their development, construction and operating efforts has led to a high volume of performing assets.

The C&I sector is challenged by a smaller geographic footprint, and is scattered with small to mid-sized developers. These developers, compared to their residential counterparts, are relatively new to the industry, and a large portion develop to sell,not to own. This dilution of assets among a smattering of C&I players, is partially responsible for a lack of aggregated portfolios and thus, volume. Like any other capital intensive industry with long term income potential, the market of institutional investors is impacted by the supply of mature alternative investment opportunities. As new institutional and strategic investors join the solar industry, developers will strengthen their balance sheets and be able to produce a larger volume of cash-flowing assets. That critical mass should be reached soon.


There’s no doubt residential players care deeply about customer acquisition cost. Without a programmatic, inflexible approach, residential solar wouldn’t exist. Utilizing a standardized document set, transaction process and asset management platform not only reduces transaction and operating costs, but it allows for legal and administrative risk mitigation when evaluating asset financings.

With so many small to mid-sized developers having a market presence in C&I, standardization has been absent, based on each developer’s unique circumstances. As an example, a C&I developer may rely upon a regional bank to provide construction and permanent debt on assets developed within the geographic footprint of the bank. The bank’s requirements might be quite different than those in other geographies, or might be less stringent than a larger nationwide bank, especially on topics involving credit and real estate. This variance can find its way into counter party agreements and ultimately prevent documents from being standardized. Another example lies in developers who develop to sell and not to own. A developer who’s looking to offload its projects, may not object to an off-taker having buyout provisions added to a solar services agreement, while those who take a long-term view may very well object. As the challenge for volume production is met by means of new capital invested into C&I, it’s conceivable to believe that larger developers will/can adopt a programmatic approach and standardize documents, process and risk analysis and can look to ABS for financing.


When it comes to credit ratings, the residential market utilizes the most accessible and widely used credit rating scale for consumers; the FICO Score. These scores have been synonymous with mapped default ratings and have been utilized by the ABS market for decades. Most solar securitizations boast average FICO scores of 720-750+.

For C&I a comparable rating scale for unrated entities has not yet been widely accepted by the industry. There are certainly benchmarks that exist that have mitigated risks in the eyes of current equity investors, but none have been universally accepted.

When financing projects with bank debt, most unrated off-takers are subjected to a bank’s corporate credit analysis. Some banks will sign off on the use of a third party’s rating scale (i.e. Moody’s Risk-Calc or shadow ratings), but will still utilize balance sheet & income statement ratio checks.

Is there a scale that can be adopted by the industry?

If there’s anyone that should be answering that question, it’s the rating agency that has assigned ratings to each of the major solar securitizations in recent years; Kroll Bond Rating Agency.

While evaluating credit risk for solar off-takers, Kroll will either a) utilize a public rating or b) conduct a credit analysis in determining probability of default for unrated entities. Each entity’s rating is weighted based on the discounted income attributed to the overall portfolio, and a Monte Carlo simulation is performed in order to forecast defaults.

In evaluating the near ABS miss of AES in 2015, it was clear that a lack of an industry accepted credit benchmarks led to underwriters wanting a higher bond spread than what was offered. In other words, credit risk wasn’t mitigated to a point where the offered spreads were reasonable.

Due to scattered ownership for C&I an absence of data exists to support the accuracy of any particular credit rating benchmark. However, as volume increases, data will exist to serve as a basis for projecting defaults on a go forward basis.

The C&I sector has a few years to answer these questions, before the ITC is stepped down, thus requiring a lower cost of capital. With new capital coming to the marketplace and developers growing their balance sheets & assets under management, we’re nearing the critical mass needed for C&I and ABS to converge.



1st: All Your Batteries Belong to Us

People’s Choice:  REC Chain
Sponsors: SunRun and DSM

The 4th annual Suncode Solar Hackathon, taking place in Oakland, CA on April 8th, 2017, saw a great turnout with fierce competition. The event, sponsored by Sunrun and DSM, and hosted by solar incubator and accelerator company Powerhouse, drew over 150 attendees, forming 23 teams for the competition. The teams were created Friday night, with each team consisting of a few developers and at least one solar industry professional, as suggested by Powerhouse.

The hacking began Friday night with the goal of launching an energy startup aimed at creating a solution to help advance solar industry growth. The teams were given suggested challenge questions to solve, but could solve alternative solar issues identified by their teams. The Sunrun sponsored challenge question that most groups aimed to solve was the following:

“Reimagine the Solar Homeowner Experience. What are customers interested in knowing about? How do they want to interact with the system? How do we maximize value for both the customer and the solar company? At what point in the process do they want a portal? Create a demonstration portal.”

The pitches began at 6:30 and continued into the late evening. Overall, the turnout of the event was great, with only standing room left by the end of the night.

My personal favorite pitch, which ended up being voted the people’s choice award, was REC Chain. The concept was to use Blockchain to validate and facilitate fair trading of Renewable Energy Certificates. The pitch seemed so complex that after the two-minute presentation, one judge asked if they had worked on this project before the Hackathon! The answer was of course no, as all participants were required to only work on their concept the day of the event. Instead, their work highlighted the advances that can be achieved over the course of a day when the bright minds of the California solar industry are gathered together.

While there were a variety of submissions, common themes that came up during the event were optimizing battery storage, qualifying marketing leads, and developing software optimization applications. There were a few that went off the beaten path, such as Independence American Media, which aims to alleviate the partisan nature of our clean tech news. The Energy Escort team also had an interesting app that simplified the process for customers to determine if they are using too much energy in real time. The app screen turns red for electrical overuse at high rate times, yellow if you should slow down on energy use, and green if it made sense to continue consuming energy.

Overall, the event embodied the entrepreneurial startup spirit that I had hoped for, and presented innovative ideas and concepts that addressed top solar industry issues. It will be interesting to follow how the teams that formed during the event develop, as this event has been the breeding grounds of numerous notable solar companies including Utility API, Powerhive, and Sunswarm.
