The Case for Corporate Solar

Signature Flight Solar Project

The U.S. is surpassing its energy transition phase and quickly normalizing renewable energy as a major resource for clean and reliable power. American businesses are at the forefront of this movement, with many companies creating internal policies for renewable energy procurement. Solar has become a major component in the sustainability initiatives of corporate entities, and solar project economics continue to become more attractive as equipment costs decline and available project structuring alternatives increase. Many U.S. CEOs are taking note of these favorable returns, and top executives from our clients – Bloomberg L.P., Swiss Re, Ricoh and more – have already begun pushing the “solar agenda” in their companies.

Onsite vs. Offsite Solar – greatest returns vs. greatest scale  

One of the key considerations for a corporation looking to go solar is deciding where to put the photovoltaic (PV) array. Many customers are considering utility-scale offsite solar projects. These grid-connected projects can allow customers to “go green” on a larger scale than with distributed generation (DG) projects, where the energy is produced where it is consumed. Utility-scale projects can provide greater contributions to internal renewable goals and RE100 certifications by letting corporates purchase bigger quantities of renewable energy, yet they typically yield smaller economic returns than onsite DG projects. Financial returns will vary, but the most profitable solar projects tend to take advantage of state, federal and utility incentives, and directly offset onsite electricity consumption. They also offer the most visibility for companies looking to publicize their sustainability initiatives and provide a way for companies to tap into solar energy directly for their day-to-day operations.

DG Solar remains heavily untapped, and the U.S. has an abundance of roof space available for new, onsite solar projects. Onsite DG should be the first step in your company’s solar procurement – monetizing your roof can yield strong economic returns before looking to offsite for greater scale.

Evaluating onsite solar includes looking at the physical attributes of the building (how many panels can fit on the building), the building’s energy usage, the solar resource (how “sunny” it is), the historical weather data and the available state, federal and utility-sponsored incentives. The size and usage of the building dictate the size of the solar PV system; typical corporate solar projects range in size from 500 kW to 2 MW. The solar resource and weather data help estimate how much energy the panels will produce per annum, and the available incentives improve the financial returns of the investment.

Favorable Utility Rates and Interconnection Policies

There are a variety of ways states use utility rates to encourage onsite DG:

  • Net-metering: The customer realizes the full retail credit for any solar energy generated by the system that is pushed onto the grid (after their onsite load is fully satisfied).
  • Feed-in-Tariff (FIT): The utility purchases a customer’s solar energy at a fixed price (PSEG-LI and LADWP currently have very strong FIT programs running).
  • Value of Distributed Energy Resources (VDER): New York is leading the way by assigning value to the total benefits that solar creates for the electrical grid (not just the monetary value of the energy itself). This includes a “stack” of values based on zonal energy prices, environmental attributes, capacity and the system’s benefits to reducing demand on the local distribution system.
  • Virtual Net-metering: In some states, a solar system can be designed offsite but corporates/rate-payers within the utility zone can get a dollar-for-dollar reduction on their bills using the full retail credit of the energy produced by the system.

Distributed Generation Incentives: States and Utilities

In addition to favorable energy rates, there are various state-level policies that further strengthen returns on onsite solar projects. Many of these policies stem from state-level Renewable Portfolio Standards (RPS) which requires that a certain portion of the energy production come from renewables.

  • Solar Renewable Energy Credits (SREC) Markets: SRECs are allotted for every MWh of solar energy produced and can be sold to the market for revenue.
  • Performance-Based Incentive (PBI) measures: PBIs are usually fixed rates ($/kWh) for a finite period of time and rely on the proper performance of the system.
  • Request for Proposals: Organizations can write a proposal to get state/utility-provided monetary incentives and to have multiple solar developers compete for a project installation.
  • Property-Assessed Clean Energy (PACE): System owners can receive financing through a lien on the property – the owner will pay back the loan through additional payments on their property taxes.

Companies can also take advantage of federal incentives: the Investment Tax Credit and the MACRS and Bonus depreciation schedule.

Financial Pathways to Solar

Owning a solar system is not the only way that a corporation can go solar at an eligible site. Creative financial structuring alternatives are opening the market to companies without available investment capital or tax liability –­ previous limiting factors for going solar. Third-party ownership alternatives provide no capital outlay options for corporations looking to take advantage of solar energy. These alternatives can be through solar operating leases, roof or site leases, or PPAs (Power Purchase Agreements). Third-party owned agreements give companies flexibility in using solar energy and can allow a pathway to ownership over time.
