Maryland Community Solar Program

Potomac Edison Maryland Community Solar Program – Subscriber Organizations

The Maryland Public Service Commission (PSC) has adopted regulations for a community solar pilot program in Maryland, with an emphasis on providing renewable energy benefits for low- and moderate-income customers. This program allows Potomac Edison customers to participate in a solar array without owning the equipment required to generate solar electricity. Community solar customers are expected to see some savings on their electric bills and all Maryland residents will benefit from more clean energy options.

Individual community solar projects will be operated by subscriber organizations (which can include utilities, retail electricity suppliers, solar developers, etc.). These organizations are approved by the PSC and the electric company serving the location of each project.

In addition, the program will encourage private investment in Maryland’s solar industry and diversify the state’s energy resource mix to meet Maryland’s Renewable Portfolio Standard and Greenhouse Gas Emissions Reduction Act goals.

Procedure to submit Subscriber Organization’s Customer List

Prior to completing the Subscriber Organization Customer List, a Subscriber Organization should already have both the subscriber organization number from the PSC as well as the interconnection number from Potomac Edison.

The completed Subscriber Organization Customer List form must be emailed to Supplier Services using the “Contact Supplier Services” form at by the 20thof each month. Per tariff rules, this form needs to be submitted prior to the start of the generation month in order for the customer information to be reviewed. Once the review has been completed, a communication will be sent to the subscriber organization informing them of the status and if any ineligible customers were found, as these ineligible customers will be treated as unsubscribed energy.  Any unsubscribed energy will be purchased from the subscriber organization at the net hourly, integrated, real-time Locational Marginal Price (LMP) for energy at the Allegheny Power Systems (APS) residual aggregate zone within PJM. All valid accounts will be programmed prior to the last day of the submission month (not the generation month).

Every month, a subscriber organization will be required to submit any changes to their original customer list, such as Add(A), Change(C), Drop(D), or even if customer remains Same(S). The customer list must be received by the 20th of each month prior to the start of the generation month.

Please attach the completed form using the “Contact Supplier Services” form at Select “MD Community Solar” from the web form drop-down selection.


Procedure to request historical usage for a Subscriber Organization’s Customer

Per the PSC Community Solar tariff, a subscriber organization must ensure and certify that any customer’s total subscriptions and net-metered generation do not exceed 200 percent of each customer’s baseline annual usage. As such, a subscriber organization may request a customer’s 12-month historical usage. In order to receive this information, the subscriber organization must provide a customer signed Letter of Authorization (LOA) form as provided below.
