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.

FAQ

Frequently asked questions

01

How do I find electricity rates for my address?

Use the get_rates_by_address tool with your full street address. The API will geocode your location and return all applicable utility rates (residential, commercial, industrial). For example, enter '1617 Cole Blvd, Golden, CO 80401' to see rates from Xcel Energy and other providers serving that area.

02

What's the difference between residential, commercial, and industrial rates?

Residential rates (sector 1) are for homes and typically have simple tiered or time-of-use structures. Commercial rates (sector 2) serve businesses and include general service and large power tariffs with demand charges. Industrial rates (sector 3) are for heavy manufacturing with the lowest per-kWh costs but complex demand and power factor adjustments. Use the specific sector tools or filter with the sector parameter.

03

Can I get complete rate structures with time-of-use details?

Yes. Set the detail parameter to 'full' when calling get_utility_rates or get_rate_detail. This returns the complete tariff structure including energyratestructure (time-of-use periods and seasonal blocks), demandratestructure, fixed charges, minimum charges, and tax adjustments. Essential for accurate solar ROI calculations and detailed energy cost modeling.

04

How do I add an MCP server to Claude Code?

Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.

05

Can Claude Code run MCP tools in headless mode?

Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.

06

How do I list all connected MCP servers?

Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
