About OpenEI MCP Server
Access the National Utility Rate Database through OpenEI — the most comprehensive source for US electricity rate data maintained by the Department of Energy. Connect OpenEI to your AI agent to instantly query utility rates by address or coordinates, analyze rate structures across residential, commercial, and industrial sectors, retrieve complete tariff details including time-of-use periods and demand charges — all through natural conversation.
GitHub Copilot Agent mode brings OpenEI data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 10 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
What you can do
- Location-Based Rate Lookup — Find all applicable utility rates by providing a street address or GPS coordinates.
- Sector-Specific Rates — Query residential, commercial, or industrial electricity rates separately.
- Complete Tariff Analysis — Retrieve full rate structures including time-of-use periods, seasonal variations, demand charges, and energy charges.
- Utility Company Research — Search and browse US electric utilities, get company details and service territories.
- Solar Feasibility Studies — Instant rate quotes for solar ROI calculations and net metering analysis.
- Energy Cost Modeling — Access detailed rate structures for accurate energy cost projections.
- Demand Charge Analysis — Understand demand charges for commercial and industrial facilities.
- Rate Comparison — Compare rate options across different utilities and locations.

OpenEI MCP Tools for VS Code Copilot (10)
These 10 tools become available when you connect OpenEI to VS Code Copilot via MCP:
get_commercial_rates
Use lat/lon or address to identify the location. Returns all available commercial tariffs including general service, large power, and time-of-use rates. Essential for commercial solar installations, demand response analysis, and business energy cost modeling. Get commercial electricity rates for a location
get_industrial_rates
Industrial rates typically include the lowest per-kWh costs but may have complex demand charges and power factor adjustments. Use for heavy manufacturing energy cost analysis, load forecasting, and industrial facility site selection. Get industrial electricity rates for a location
get_rate_detail
Returns the full rate structure including energy charges, demand charges, fixed charges, minimum charges, time-of-use periods, seasonal variations, and applicable taxes. Use this after identifying a rate ID from get_utility_rates to get exhaustive details for cost modeling or bill analysis. Get detailed information about a specific utility rate/tariff
get_rates_by_address
Simply provide a street address and the API will geocode it and identify the serving utility and applicable rates. Perfect for solar installers providing instant rate quotes to customers, or homeowners checking their electricity rates. Returns all available rate options at that address. Get utility rates for a specific street address
get_rates_by_coordinates
Automatically identifies the serving utility for that location and returns applicable rates. Essential for solar installers, energy consultants, and site selection analysis. Returns residential, commercial, and industrial rates if available. Set detail=full for complete rate structures. Get utility rates for a location using GPS coordinates
get_residential_rates
Perfect for homeowners comparing electricity costs, evaluating solar ROI, or understanding time-of-use rate options. Returns all residential tariffs including tiered rates, time-of-use plans, and electric vehicle charging rates. Get residential electricity rates for a location
get_utility_detail
Returns the utility name, address, contact information, service territory, owned generation resources, and associated rates.
