What we cover

The beats.

Six categories shape how we cover the energy transition. Each gets its own visual identity, its own data sources, and its own angle on the story.

Dispatch

Flagship reporting on the people, projects, and capital shaping the buildout. Long-form data stories with a single thesis.

Anchor
Growth

DER adoption, VPP enrollment, residential storage, EV-grid integration. The retail edge of the energy transition.

DER · VPPs
Policy

FERC, state regulators, ISO market design, interconnection reform. Where rules become market structure.

Regulation
Capital

Climate VC rounds, M&A, infrastructure funds, PPAs, and the financing structures behind the buildout.

VC · M&A
Markets

Wholesale prices, capacity auctions, ancillary services, and the unit economics that sit underneath every project decision.

ERCOT · CAISO · PJM
Grid Tech

Software, hardware, and AI infrastructure reshaping how power moves. From DERMS to data centers.
