IRS releases solar Investment Tax Credit qualification guidance

investment tax credit

The Internal Revenue Service (IRS) released guidance establishing when construction starts for solar projects under tax law, allowing developers to invest with confidence in new solar projects.

“The IRS has taken an important step forward with this guidance and provided certainty that will help solar project sponsors finance and build more solar,” Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association (SEIA). “Our members have been working hard to secure financing for projects and keep them on track to meet critical development and construction milestones. This guidance provides them with a strong timeline for keeping up momentum for new projects.”


The guidance, Notice 2018-59, provides two methods to establish when construction of a solar facility starts to qualify for the solar investment tax credit (ITC):

(1) starting physical work of a significant nature or

(2) meeting the ‘five percent safe harbor test’ (i.e., paying or incurring five percent or more of the total cost of the facility in the year that construction begins).

“In the absence of this commence construction guidance, tax equity partners were growing cautious about project risk,” Hopper continued. “Solar projects are helping modernize and secure our energy infrastructure, creating jobs and bringing clean energy to communities around the United States. We look forward to working with the IRS to ensure the guidance is implemented in a way that keeps this solar economic engine moving forward.”

Midwest Values: How to identify market opportunities outside of solar hotbeds

A good starting point for identifying an advantageous solar market is to look at the average retail cost of electricity. For behind-the-meter (BTM) solar projects, high retail electricity prices enable solar project economics to look more attractive. The opposite is also true. Low prices make it hard for projects to pencil out. This is a primary reason why the Midwest rooftop solar market has lagged behind other regions of the country that have experienced more rapid growth.

The U.S. Energy Information Administration (EIA) is a great resource for sourcing impartial information on energy costs throughout the country. EIA publishes a monthly report which shows the average price of electricity for each state by sector of use. Below is a summary of EIA energy cost data for the five biggest Midwestern states, in comparison to California, the leading BTM solar state in the country.

Looking at the average retail electricity price by state provides a high-level filter for identifying viable BTM solar market opportunities. But the statewide average blended rate does not tell the full story. In order to really pinpoint tangible customer opportunities, we need to look at both the utility level and rate tariff level. It is not uncommon for there to be a wide amount of variance between different rate schedules within a given state. For example, the average residential cost of electricity could be 13 cents per kilowatt-hour, but specific rate schedules could range from under $0.10/kWh to over $0.20/kWh.

retail electricity prices

It’s also important to point out that the average cost of electricity is not the same as the average blended savings of a solar project. When it comes to quantifying how much solar is worth, average blended savings, which is sometimes referred to as the value of solar, is the truest representation of value. The calculation for average blended savings is very simple: first year dollar savings divided by total first year solar production. This expresses the value of solar on a $/kWh basis. We published a video tutorial entitled “How to Accurately Calculate the Avoided Cost of a Solar Project,” which explores this concept in depth.

Accurately calculating the value of solar for a specific customer requires good software. This is especially true in instances where the utility rate tariff is complex, like a rate schedule that has time-of-use (TOU) rates, demand charges or an inclining or declining block structure. Energy Toolbase specializes in objectively quantifying the avoided cost on complicated rate structures. Our software platform is used by solar companies of all shapes and sizes in markets throughout the United States to accurately and transparently determine savings for a given customer. Let’s look at two rate schedules in the state of Illinois.

illinois rate schedules

The Ameren Illinois Co. rate schedule features a declining block structure, meaning the energy used above the 800 kWh threshold is priced at a lower rate. Assuming a high usage customer of 1,250 kWh month of usage, Energy Toolbase calculated the customer’s average blended cost of energy at $0.114/kWh. Assuming an 11.2 kW DC solar system, which offsets 90 percent of annual kWh usage, the value of solar is calculated at $0.102/kWh. Note: In a deregulated state like Illinois, be mindful of which entity is billing the generation supply charge, which will affect the customers’ $/kWh volumetric energy rate.

The ComEd, BES-Medium schedule is a typical C&I rate in that it has $/kWh energy, $/kW demand, and $ fixed charges. Assuming a customer uses 10,000 kWh month and a peak demand of 50 kW, Energy Toolbase calculated the customers average blended cost at $0.108/kWh. Assuming an 80 kW DC rated solar system, offsetting 80 percent of annual kWh usage, the value of solar would come in at $0.079/kWh.

These are two generalized examples. Other customers on these same rates could have very different average blended cost and value of solar calculations, especially if the $/kWh generation supply charge was meaningfully different. Therefore, when searching for favorable market opportunities we recommend running several sample projects to establish the range for both cost and savings.

California to launch three programs to improve low-income community access to solar

thumbs up

Right on cue after our Install Inequality feature this week, the California Public Utilities Commission (CPUC) adopted three new programs to promote the installation of solar energy to serve customers in disadvantaged communities.

“Transitioning to a clean economy must include all Californians. Targeting solar investments in low income and disadvantaged communities will help ensure that all Californians have access to all the benefits of solar, whether on their roofs or nearby in their neighborhoods,” said Commissioner Martha Guzman Aceves.

The programs approved include

1) The Disadvantaged Communities – Single-family Solar Homes (DAC-SASH) program, modeled after the existing Single-family Affordable Solar Homes (SASH) Program, will provide up-front financial incentives toward the installation of solar systems for low income homeowners. The program will be available to low income customers who are resident-owners of single-family homes in disadvantaged communities. The incentives will assist low income customers in overcoming barriers to the installation of solar energy, such as a lack of up-front capital or credit needed to finance solar installation.

2) The Disadvantaged Communities – Green Tariff (DAC-Green Tariff) program will provide a 20 percent bill discount to customers in disadvantaged communities. This will allow customers to choose clean energy options without the need to own their home and without the cost of installing their own solar systems. The program is modeled after the existing Green Tariff portion of the Green Tariff/Shared Renewables Programs. It will be available to customers who meet the income eligibility requirements for the California Alternate Rates for Energy (CARE) and Family Electric Rate Assistance programs.

3) The Community Solar Green Tariff program is similar to the DAC Green Tariff program, and will also provide a 20 percent bill discount. This program will allow primarily low income customers in disadvantaged communities to benefit from the development of solar generation projects located in or near their communities. The communities will work with a local non-profit or local government “sponsor” to organize community interest and present siting locations to the utility; the sponsor can also receive an incentive for its efforts.

Both the DAC-SASH and DAC-Green Tariff programs will be funded first through greenhouse gas allowance proceeds. If such funds are exhausted, the programs would be funded through public purpose program funds.
