Real questions, real data, real answers — from actual Pathfinder sessions.
Pathfinder handles the complexity so you can focus on the insights that matter.
Ask about capacity, costs, emissions, technology deployment, or any aspect of an analysis — in plain English.
Pathfinder understands the structure of energy models, finds the relevant data, computes statistics, and determines the best way to present the answer.
Get interactive charts, maps, infographics, and downloadable data — the kind of outputs that used to take days, delivered in seconds.
Explore how different policy designs affect technology deployment, costs, and emissions across scenarios and regions.
Investigate capacity expansion, transmission buildout, storage economics, and resource adequacy across long-term planning horizons.
Assess technology competitiveness, market sizing, deployment timelines, and risk exposure across a wide range of plausible futures.
Extract data for publications, compare model outcomes, and build on EER's analytical foundation with full export capabilities.
Pathfinder gives you access to a curated set of datasets — available as part of a core subscription or developed during consulting engagements. These datasets are the fuel behind a natural language interface that lets you ask questions about our models, data, input assumptions, outputs, insights, and key takeaways.
Subscribe to continuously updated datasets from our flagship analyses — including the Annual Decarbonization Perspective for the U.S. and Europe. New results are delivered as they're published, giving you a living connection to the most current energy transition research available.
Datasets produced during consulting engagements live in Pathfinder alongside everything else. Your team can return to any past analysis, ask new questions, build new charts, and extract new value — long after the engagement is complete.
Across every dataset, you can explore capacity and deployment, generation and dispatch, investment and system costs, technology mix and market share, operational behavior, emissions trajectories, storage, transmission, and more — all through the same conversational interface.
RIO is the only capacity expansion model that co-optimizes across the entire energy economy — electricity, pipeline gas, hydrogen, liquid fuels, heat, and transport — in a single solve. Pathfinder lets you explore every dimension of that output.
Not just the power sector. RIO simultaneously optimizes investment and operations across electricity, pipeline gas, hydrogen networks, liquid fuels, industrial heat, and transportation — capturing the sector coupling that drives real-world economics.
From Allam-cycle power plants, molten salt reactors, and next-generation geothermal to iron-air batteries, compressed air, vanadium redox flow, liquid air, and CO₂ dome storage — plus electrified DRI steel, Fischer-Tropsch synthetic fuels, and thermal energy storage. RIO models technologies other platforms don't even have categories for.
Hourly dispatch for every energy carrier — not just electricity, but hydrogen, pipeline gas, heat, and liquid fuels. This temporal granularity is what makes it possible to accurately value flexible resources, long-duration storage, and variable renewables.
Transmission topology, pipeline routing, and distribution feeder capacity are co-optimized with generation and storage — not treated as fixed inputs. The model decides what to build, where to build it, and when.
Technology adoption isn't prescribed — it can be solved. RIO can endogenize consumer-level decision-making across vehicles, heating systems, industrial processes, and appliances, letting the economics determine the pace and direction of electrification.
Demand response, managed EV charging, flexible industrial processes, and thermal storage are optimized as system resources — capturing the full value of load flexibility alongside supply-side investment.
ENSEMBLE is an automated scenario generator built on top of RIO. Rather than finding a single least-cost answer, it systematically explores hundreds of near-optimal system configurations — delivering far greater coverage of potential futures and richer technology deployment pathways than traditional scenario analysis can achieve.
Traditional models produce a single "optimal" pathway that depends heavily on input assumptions. ENSEMBLE generates 100+ complete system solutions, each within a small cost tolerance of the true optimum, revealing the diversity of viable futures the energy system could take.
Pathfinder makes this data accessible by automatically computing ensemble statistics — median, P5–P95 percentile bands, standard deviation — and presenting results through purpose-built fan charts and uncertainty visualizations.
Hand-crafted scenarios explore a handful of futures. ENSEMBLE algorithmically finds orders of magnitude more viable configurations — capturing interactions and trade-offs that scenario analysis misses entirely.
Every run is a complete, internally consistent system solution with its own technology mix, capacity deployment, and operational pattern — not a sensitivity on a single variable.
Some investments appear in virtually every near-optimal solution. Others swing dramatically. ENSEMBLE shows you which decisions are robust — and where flexibility has the highest value.
Emporium is our production cost model — simulating real-world electricity market operations with detailed unit commitment, multi-sector coupling, and hourly price formation across interconnected regions.
Through Pathfinder, every simulated market price, dispatch decision, and revenue stream becomes explorable and downloadable. Explore locational marginal prices, generator revenues, curtailment economics, storage arbitrage value, and reserve costs — then export the raw data for your own analysis.
Paired with ENSEMBLE, Emporium becomes even more powerful. Running market simulations across hundreds of alternative capacity buildouts reveals that deployment uncertainty — not fuel prices or demand growth — is by far the greatest source of risk to market revenues. Pathfinder lets you explore that risk surface directly.
Pathfinder is also the platform for interacting with our custom visualizations, geospatial analyses, and other research products.
Downscaled mapping of candidate project areas, land-use impacts, siting constraints, and transmission corridors — the same spatial detail behind our landmark national analyses.
Visualizations designed to tell the story of the energy transition — not generic charts, but narrative-driven graphics that surface the insights and communicate them clearly. Generated on the fly and fully interactive.
Download any result as CSV, or generate polished PDF reports and PowerPoint presentations ready for stakeholders and decision-makers.
