DC solar fees

DC solar fees: what’s happening with them?

Washington, DC, like many areas in the U.S., has some great incentives if you’re looking to go solar. Recently, however, some residents have received an unpleasant surprise after their installer submitted the permit application for their system: additional fees, which are noted to be necessary to update the grid in order for it to support solar in their area. In this article, we’ll break down these fees, reference some first-hand information from local DC installers, and share what you can ask and do if you learn of additional potential fees when looking to go solar in the DC area.


Key takeaways


  • Pepco is one of the leading electric utilities in the DC area, serving almost 900,000 customers.
  • Approximately 15 percent of DC residents who apply for solar permits on their homes are getting letters notifying them of additional fees (at an average of $9,560 in fees) necessary to install solar at their home.
  • Local DC installers are helping residents navigate the fees and how to make going solar as affordable as possible.
  • Whether you live in DC or elsewhere in the U.S., you can use the EnergySage Marketplace to find trusted installers in your area to go solar and compare quotes from them.

DC’s electrical market and solar incentives

Pepco (Potomac Electric Power Company) currently provides electricity to 894,000 customers throughout the District of Columbia (DC) and Maryland. DC is often cited as a leader of laws and policies that address both the impacts of climate change as well as energy unaffordability and inequity. Specifically, DC has mandated a 100 percent Renewable Portfolio Standard (RPS) by 2032 and the Mayor has announced a policy to become carbon neutral by 2050. Solar is a necessary and essential component to meeting these climate and clean energy objectives and the DC Council has gone as far as mandating that 10 percent of the renewable energy portfolio must be met from solar facilities located within DC by 2041.

Pepco and DC in general promote some very favorable conditions for going solar due to a few main factors:

Net metering

In DC, if you produce more electricity than you use in a month, your next month’s electricity bill will be credited with your excess energy through net metering. If your solar system is under 100 kW, you’ll be credited at the full retail rate. If you’re a business owner and your system is over 100 kW, you’ll be credited at the generation rate. These credits never expire, and they may be used in winter months when you’re producing less energy. You do have to apply for net metering through Pepco, which your installer will help you with.

SRECs

Solar renewable energy certificates (SRECs) are a performance-based solar incentive that allow you to earn additional income from solar electricity generation. In DC, as a homeowner, you can earn one SREC for every megawatt hour (MWh), or 1,000 kilowatt hours (kWh), of electricity your solar system generates. 

Pepco doesn’t manage SRECs in DC; rather, they’re administered by the D.C. Public Service Commission administers. DC has some favorable SRECs, trading at $382.50 as of March 2022. If you have a 10 kW solar panel system, it will produce about 10 to 13 MWh of electricity per year on average, which will earn you 10 to 13 SRECs annually. So, at the current SREC rate, you’d earn $3,825 (or more) annually. If you live in DC, you can visit the Public Service Commission website to see detailed information on SRECs or apply for them. 

What solar fees are some DC residents seeing?

The fees residents are getting charged by Pepco vary depending on the specific area they’re located in: there’s no set fee showing up in these instances and some people aren’t getting charged any fees at all. However, according to a survey in the DC area by The Chesapeake Solar & Storage Association’s (CHESSA) that was sent to installers, the average upgrade cost was $9,560, which is obviously a substantial amount added to the average overall cost of going solar, which usually ranges between $25,000 and $30,000 prior to any incentives and rebates.

CHESSA surveyed installers and found that 94 projects were reported to have received requirements for solar system downsizing, distribution system upgrades, or both, beginning in April 2021. Detailed data showed that projects averaged a 5 kW downsizing requirement per project and/or a $9,560 upgrade cost per project. (A project refers to an individual home’s solar panel installation, though some of these projects may be commercial or industrial solar projects). 

What are some other DC solar costs?


In addition to the fees we’re discussing in this article, some of the other costs associated with going solar that are more specific to DC include:

  • Potential increased installation costs for flat roofs: In the DC area, flat roofs are common. Installing solar on flat roofs may mean added installation costs in the form of specialized equipment, but you can work with your local solar installer to design the best option for your specific roof and home.
  • Net metering application fee: Pepco does have an application fee to apply for net metering, which is either $100 or $500, depending on your solar system’s size. Your installer will help you apply for a net metering interconnection through Pepco’s online as part of the installation process.

What’s the overall estimated impact to DC solar?

A 6.8 kW solar system would usually power the average American household, though your needs will vary depending on various factors such as the size of your home and your energy usage. In CHESSA’s survey, the average system included was 7.7 kW – and of the 907 systems included, approximately half were asked to downsize. At an average downsize request of 5 kW per system, that implies a 500 kW total potential reduction in annual residential capacity throughout the DC area.

CleanGrid Advisors, who ran the survey for CHESSA, analyzed these downsizing and upgrade cost requirements to the District’s total annual volume of residential interconnections, and determined that approximately 200 solar projects each year could be affected in DC. This represents 500 kW annually in potentially lost system capacity (people having to reduce the size of their solar system) and/or over $1,600,000 in required system upgrade costs. 

Why increases in solar may require upgrades to electrical grids


It is legitimate that some electrical grids may require updates — but that’s not usually because of solar. Many electrical grids have dated infrastructure and are looking to make updates, specifically focusing on increasing the capacity of renewable energy to reduce the reliance on fossil fuels for homeowners and businesses in the area. DC isn’t the only area to face this issue — others like Hawaii addressed upgrade costs by adding a small fee of approximately $1 per month to electrical bills to cover electrical grid upgrade costs. So, while upgrades may be necessary, charging residents upgrade fees to use renewable solar energy is a bit counterintuitive to these goals.

What options do you have if you get a letter indicating additional fees from Pepco?

One of the best things you can do is touch base with your solar installer immediately. They have likely dealt with these circumstances before and may be able to help you by either absorbing some of the fees or providing suggestions based on their recent communications with Pepco. You may be able to dispute the upgrade fee, which your installer can also guide you through. 

Another issue you may encounter if you’re a  DC resident trying to go solar is that this process can delay your solar project timeline because of the time needed for your installer to review the information, work with Pepco, and, in some cases, wait for the grid infrastructure upgrades to be made. Fortunately, many DC-area solar installers are helping their customers navigate the process and are in regular conversations with Pepco. They’re also requesting final cost letters from Pepco because in some instances there have been updates provided that an upgrade isn’t needed after all – meaning you wouldn’t have to pay fees! 

What’s the status of upgrade fees? 

Because of the potential negative impact to the DC solar industry, several organizations are working to help DC residents and businesses address this issue. A couple of public filings have recently been submitted, including one from CHESSA on February 17, 2022. Given the significant percentage of solar system installations impacted, the reports that these types of requirements are new, and the substantial downsizing and upgrade costs, CHESSA is requesting in their public filing that Pepco explain the changes, identify the root causes, and collaborate with the industry to minimize capacity losses and costs. Specifically, they want Pepco to take the following two actions:

1. Provide stakeholders with a comprehensive explanation of the change in requirements that occurred in April 2021. The explanation should include any changes to policies, practices, evaluation methods, and other circumstances that have led to these new requirements being imposed. 

2. After providing information on the root causes of the changes, Pepco should work with stakeholders to develop approaches to limiting system downsizing and upgrade requirements.  

Only time will tell what the result will be from these filings, but hopefully some more details will become available and more solutions will arise to help DC customers cover electrical grid upgrade costs and go solar. 

The bottom line about going solar in DC

While additional fees should warrant a reasonable explanation, there are still a lot of great benefits if you’re looking to go solar in DC! So, the reality is that even with fees, you can likely make your money back on your solar investment within a few years (the average solar payback period is 8.7 years on EnergySage). You can determine your individual payback period with the help of your installer and/or lender (if you’re financing solar) by accounting for any fees, installation costs, and financing costs in your calculations.

    200 amp 240 VAC service to a typical modern home can technically pull up to 48 kw from the utility lines. And yet they are limiting systems to 5 kw? I would assume the local electrical infrastructure is in dire need of upgrade.

    On another note, if local utility infrastructure truely is the limiting factor, why not approve/encourage in home grid tie storage so that demand and supply limiting to/from the grid can be implemented by algorithm? It would be more economic and fair to the PV host, and benefit the neighborhood, and utility.
