Representative Business, Corporate, and Commercial Litigation Matters

  • Calfee is providing legal strategy and defense of a complaint filed against an independent organization that manages and administers significant energy markets in North America. Specifically, Calfee is assisting the client in the defense of a complaint brought by a national solar energy trade association, alleging that the client's Tariff is unjust and unreasonable.
  • Calfee is providing direction on legal and regulatory strategy, draft filing, and pre-filed testimony and assisting in regulatory compliance and discovery processes for an independent organization that manages and administers significant energy markets in North America. Specifically, Calfee manages the stakeholder processes and presentations and assists with the client’s compliance with FERC Order No. 2222 directing RTOs to allow distributed energy resources (DER) to participate in wholesale electricity markets. This matter is of high importance to the client and involves FERC’s direction in Order No. 2222 and removes barriers to allow DERs to participate in wholesale markets, therefore expanding the grid to previously precluded resources. The rules developed through the stakeholder engagement and filings related to this FERC’s mandate will allow the expansion of wholesale market participation to aggregations of smart residential devices like thermostats and electric vehicle chargers.
