1. A. This chapter applies to a small generator facility seeking to interconnect and operate in parallel with the electric distribution system. All small generator facilities shall interconnect under requirements in this chapter or under the physical interconnection requirements of the PJM Interconnection, LLC under the authority of FERC.

2. B. A small generator facility seeking to interconnect and operate in parallel with the electric distribution system under this chapter shall meet one of the following criteria:

   1. (1) The small generator facility is a qualifying facility pursuant to the Public Utility Regulatory Policies Act that intends to make sales at a rate approved by the Maryland Commission;
   2. (2) The small generator facility is not a qualifying facility pursuant to the Public Utility Regulatory Policies Act and does not intend to make sales of wholesale electric energy through the PJM Interconnection, LLC;
   3. (3) The small generator facility intends to make sales of wholesale electric energy through the PJM Interconnection, LLC at an electric distribution interconnection facility where there has been no prior FERC jurisdictional service;
   4. (4) The small generator facility intends to make sales of wholesale electric energy through the PJM Interconnection, LLC only at an electric distribution interconnection facility through participation in a distributed energy resource aggregation; or
   5. (5) The small generator facility will be interconnected to an electric distribution circuit and its energy will not be transmitted across state lines for a wholesale customer other than the electric distribution owner.
3. C. Market processes under FERC jurisdiction that are administered by the PJM Interconnection, LLC may not impede the interconnection timeline requirements in this chapter unless the utility has good cause to believe that equipment upgrades exceeding minor equipment modifications and related modifications to the interconnection agreement will be needed to facilitate these market processes. In these cases, the utility shall notify the interconnection customer in writing of their rationale to delay approval of the interconnection request until the conclusion of the PJM Interconnection, LLC's market process study.
4. D. In situations where an interconnected small generator facility project intends to change their energy sales strategy from market processes under FERC jurisdiction to retail processes under this chapter, the small generator facility shall submit an interconnection request.
