Grid Reform in Maryland

What is grid reform?

The way we produce and deliver electricity is changing. Distributed solar energy and other renewables are pushing changes to our electrical grids and the rules that manage them.

Grid reform in Maryland

Maryland’s Public Service Commission (PSC) has undertaken a proceeding, PC 44, which may significantly change the rules for how we generate and receive electricity. In January 2017, the Commission announced the formation of several working groups as part of the proceeding, as well as a study to assess the benefits and costs of distributed solar in Maryland.

The working groups will provide commissioners with feedback on the key components of Maryland’s electricity sector that, according to the Commission, are “ripe for action in this proceeding”. Pilot projects, experimental electricity tariffs, and development of rules for these topics may be incorporated into the proceeding, as well. This is our opportunity to ensure Maryland’s community of solar supporters is represented.

We are also working with MEDA (Marylanders for Energy Democracy and Affordability), a diverse network of public interest organizations and residents participating in the PC44 process with the goal of creating a fair, equitable, and democratic transition to a clean, reliable, and affordable energy economy.

About the working groups

The PSC often uses stakeholder working groups to address technical and regulatory issues and provide recommendations. The Commission highly values any consensus positions reached by working group members. Commission staff members lead the groups and are responsible for reporting back to the Commission on what the working group discovered. Over the course of several months, the working groups will meet and examine issues related to the topic and the Commission’s directives for that topic (different types of rates, pilot programs, etc.). During working group discussions, participants will have opportunities to express their views and contribute to the topic at hand. For example, during a discussion about how the value of solar electricity should be compensated at different times of the day, a solar homeowner has a particular perspective to add to the conversation and may be invited to present original commentary.

Working groups will likely be conducted through in-person and dial-in conference calls. In-person meetings will most likely be held in the downtown Baltimore offices of the PSC and should have an option for participants to dial-in and participate remotely.

List of Working Groups

Rate Design

This group will discuss “Time of Use” (TOU) rates, or rates that vary according to when the customer consumes electricity.  Of particular interest will be whether varying electric rates by time of use according to real-time fluctuations in the costs and benefits of distributed solar can serve to empower customers and provide clear market signals. Several of these working groups will consider possible pilot programs. One such pilot could be implementing TOU rates for customers with distributed solar. A pilot of TOU rates for solar customers may, for example, include a higher credit value for energy produced at when the grid needs it most and a lower credit value for when the grid needs it less.

  • February 2017 to June 2017: Develop pilot programs for traditional electric service
  • Spring 2017 to December 2017: Value of Solar study conducted by consultant
  • November 2018:  Value of Solar Final report released
  • July 2017 to June 2018: Traditional electric service pilot programs occur, if approved
  • January 2018 to May 2018: Propose plan to develop DER-specific pilot program

Leader: Jon Kucskar,

Electric Vehicles

This group will discuss electric vehicle (EV) specific tariffs, TOU rates, infrastructure investment by utilities, partnerships for vehicle fleet electrification, and other measures to expand and support electric vehicle use in the state.

  • February 2017 to December 2017: Develop new EV-related tariffs and utility investment in charging infrastructure
  • January 2018 to June 2018: Consider new rate structures for corporate fleets + workplace/commercial chargers

Leader: Marissa Gillett,

Competitive Markets and Customer Choice

This group will discuss developing statewide standards for smart meter data sharing and improving the competition, transparency, and customer-friendliness of retail choice.

  • February 2017 to June 2017: Developer proposal for AMI data sharing system
  • July 2017 to December 2017: Propose retail supply changes to improve competition, transparency & experience

Leader: Odogwuobi Linton,

Interconnection Process

This group will discuss improvements to solar interconnection standards and procedures, the possible mandated use of smart inverters, expanded availability of hosting capacity maps for siting solar and other distributed energy resources, and cost allocation and system capacity issues regarding large and mid-size solar facilities.

  • February 2017 to July 2017: Assess current residential interconnection process
  • August 2017 to March 2017: Develop regulations for residential interconnection improvements
  • July 2017 to June 2018: Assess provision of hosting capacity information to the public
  • July 2017 to June 2018: Review cost allocation and capacity issues for mid-size and large facilities

Leader: Jon Kucskar,

Energy Storage

This group will discuss possible rules to define residential energy storage, its interconnection to the grid, and map out how it’s classified in rules, tariffs, and policies.  It will also determine appropriate criteria for deciding whether utilities should invest in energy storage and how they should be compensated.

  • May 2017 to June 2018: Develop regulations for defining and classifying residential storage
  • May 2017 to June 2018: Develop proposals for storage as a utility asset + non-wire alternatives (NWA)

Leader: Andrew Johnston,

Distribution System Planning

This group will discuss the components of distribution planning, what areas the Commission should focus on, and whether it should authorize a study on key topics.
