The NCEP T&D Resource Catalog documents an ongoing conversation about the intersection and coordination of the transmission and distribution systems. The documents contained in the resource catalog provide state electricity system decision-makers with examples and resources to support their decision making.

NCEP will update this catalog as new materials become available. Please send any suggestions for additions to the Resource Catalog to Kerry Worthington with your recommendations for where the resource(s) best belong in the tables.

At its 2018 Annual Meeting, NCEP launched the theme, “Transmission & Distribution System Coordination in Planning, Operations, and Markets” in light of the increasing prevalence of distributed energy resources (DERs) on the grid and their current and potential future impacts at multiple levels of the electricity system. NCEP invited expert presenters and hosted a facilitated dialogue on members’ questions and resources that might address their questions. NCEP released a Compendium of Resources based on the meeting in September 2018. Since then, new information has become available at an unprecedented rate, requiring an easy-to-update, accessible location: the Resource Catalog. At each subsequent Annual Meeting, NCEP held expert presentations and a facilitated dialogue, adding those examples and resources to the Resource Catalog.

The Resource Catalog is divided into three main categories with two subcategories, explained below.
Planning – Careful planning of new transmission and distribution infrastructure is critical for the successful integration of distributed energy resources (DERs) to the distribution system without negatively impacting the bulk power system. Several pilot projects and policy approaches have been used to support the planning of transmission and distribution (T&D) infrastructure. This section includes energy efficiency.
Operations – Grid operations are critical to the safe, reliable, and efficient delivery of electricity. Currently, distribution operators and regional transmission operators (RTOs) do not consistently have visibility and situational awareness of the location, status, and output of DERs. In the future, as DERs continue to grow in number and magnitude, T&D operators will need to establish and/or improve coordination and communication with each other in new ways to maintain reliable operation of their respective systems, and with the electric system as a whole. This section includes resilience, reliability, large customers, and electric vehicles.
Markets – Increased adoption of a range of DER technologies has the potential to change or activate retail and wholesale markets (i.e., at the distribution and transmission levels). Key to exploring the potential effects is understanding the benefits and services DERs provide; how utilities, distribution grid operators, and transmission operators value those services; and ultimately working out how and who will transact for these services. This section includes state policies and incentives, rate design, and valuation.
Resources falling into these three categories are then split between either:
(1) an example of a policy or pilot project, or
(2) a resource for either implementation or the marketplace of ideas
For example: “Planning – Example,” “Planning – Resource,” “Markets – Resource”.
