Transforming Maryland’s Electric Grid (PC44)

With a goal of ensuring that Maryland’s electric grid is customer-centered, affordable, reliable and environmentally sustainable, the Public Service Commission initiated a proceeding, titled Public Conference 44 (PC44) to launch a targeted review of electric distribution systems in Maryland. This proceeding builds on two Commission technical conferences held recently that examined rate-related issues affecting the deployment of distributed energy resources (such as solar) and electric vehicles.

This proceeding aims to explore issues that will maximize benefits and choice to Maryland electric customers and, in particular, assess how the evolving electric grid impacts low- and moderate-income ratepayers.

In the Commission’s initial notice, seven topics were suggested for consideration in this proceeding. After reviewing written and oral comments, the Commission issued a notice on January 31, 2017 establishing guiding principles and amending the list of topics to better align with possible long-term outcomes. They include:

1. Rate Design
(Molly Knoll and David Littell, Workgroup Leaders)
2. Electric Vehicles
(Case No. 9478; Amanda Best, Workgroup Leader)
EV Pilot Fact Sheet
3. Competitive Markets and Customer Choice
(Rule Making 62; Joey Chen and Molly Knoll, Workgroup Leaders)
4. Interconnection Process
(Rule Making 61; John Borkoski, Workgroup Leader)
5. Energy Storage
(Kristin Lawrence, Workgroup Leader)
6. Distribution System Planning (if sufficient funding available)
