Energy and utilities litigation is distinctive because the underlying dispute frequently starts, and sometimes ends, inside a regulatory forum rather than a court: state public utility commissions and, for interstate matters, the Federal Energy Regulatory Commission set the rates a utility may charge, review whether costs were prudently incurred before allowing recovery, and approve or reject the terms on which utilities interconnect and serve customers. A ratepayer or competitor challenging utility conduct typically must exhaust the applicable agency process before a court will hear the dispute, and the standard of review that follows — often deferential to agency fact-finding — shapes what is realistically achievable once the matter does reach litigation. Prudence review sits at the center of many rate disputes: a utility that made a reasonable decision at the time, even one that turned out poorly, is generally entitled to cost recovery, while imprudent spending is not, making the timing and information available to decision-makers a recurring factual battleground.

Because utilities operate as regulated monopolies or hold market power within a service territory, disputes also arise over interconnection terms for new generation, curtailment and dispatch decisions, and whether a utility's conduct toward competitors or independent power producers violates its tariff obligations or applicable open-access rules. These cases often braid together contract claims under interconnection or power purchase agreements, statutory claims under state or federal energy statutes, and administrative review of the agency decision itself, so a single dispute can proceed on parallel tracks with different standards, different records, and different timelines. Intervenors — competing generators, consumer advocates, or large industrial customers — frequently participate directly in the agency proceeding itself, shaping the record before any court ever sees the case. The regulatory record compiled at the agency level frequently becomes the primary evidentiary record for any later judicial review, which raises the stakes of the initial agency proceeding well beyond its own outcome, since a gap or concession made during the administrative phase can be very difficult to revisit later.

The choice of forum and the exhaustion requirement usually resolve before the substantive dispute does, since a party that skips or shortchanges the agency process risks losing the claim on procedural grounds regardless of merit. Prudence disputes turn heavily on the information available at the time a decision was made rather than hindsight, so the strength of contemporaneous documentation often outweighs the ultimate outcome of the utility's decision. Because rate cases affect an entire customer class and interconnection disputes affect an entire generation queue, settlement posture is frequently shaped by precedential exposure across future proceedings, not just the dollar amount in the case at hand.
