Frequently asked questions about the OpenEI MCP Server
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.
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.
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.
