Market intelligence across generation, grid, and energy transition.
1,860+ published studies covering renewables, transmission & distribution, storage, oil & gas, and digital energy — sized bottom-up and top-down, validated by our dedicated Energy & Power research team, and delivered with country-level detail.
The Energy & Power Research Team
This vertical is covered by a dedicated research group inside Fundamental Business Insights that tracks the global energy and power industry full-time. Our analysts follow generation-mix shifts, grid modernization spend, storage economics, upstream/downstream oil & gas activity, and decarbonization policy as they happen — not just at the point a report is commissioned.
Every estimate in this vertical is built from primary conversations with utilities, equipment OEMs, and energy developers, and cross-checked against regulatory filings, national energy statistics, and project-level capacity data, then reconciled through both bottom-up and top-down modeling before an internal quality review.
Who we interview
Utility planners, grid operators, project developers, and upstream & downstream oil and gas executives.
Policy fluency
Analysts track subsidy regimes, grid codes, and decarbonization mandates so capacity and demand forecasts reflect real timelines.
Capacity & project modeling
Forecasts factor in installed capacity pipelines and project commissioning timelines, not just end-market demand curves.
