Estimate Solar Energy Generation for Any Location
Calculate how much electricity a solar installation would generate at any UK location based on irradiance and panel configuration.
Check Live Electricity Prices by Region
Get current electricity prices for any UK region to optimise energy usage and reduce bills.
Quick answer: Use the Energy Data tool through ToolRouter to check live electricity prices by region directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolElectricity prices in the UK vary significantly by region and fluctuate throughout the day, but most consumers and businesses have no visibility into these changes. Smart appliances, EV chargers, and battery storage systems can all be scheduled to use cheaper electricity — but only if you know when and where prices are lowest.
The electricity_prices skill returns live and forecast half-hourly electricity prices by region, including the wholesale rate. You can identify the cheapest periods in the next 24 hours, compare regional pricing, and plan high-consumption activities accordingly. The data is suitable for both manual planning and automated energy management systems.
Homeowners with solar panels or EV chargers, building managers optimising commercial energy costs, and developers building smart home integrations all rely on this data to make time-of-use decisions that meaningfully reduce energy bills.
How to check live electricity prices by region with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude interprets electricity pricing data in plain English — identifying the cheapest windows of the day, explaining what price spikes mean for your bill, and recommending when to run dishwashers, charge EVs, or export solar energy. It turns half-hourly price tables into actionable daily schedules without requiring any technical knowledge.

How to check live electricity prices by region with Claude
Once connected (see setup above), use the Energy Data tool:
- Ask: "Get electricity prices for the South West region for today using energy-data"
- Claude returns half-hourly prices for the requested region
- Ask: "When are the cheapest three hours to run high-consumption appliances today?"
- Request: "How much could I save by shifting my EV charging to off-peak times?"
Example prompt for Claude
Try this with Claude using the Energy Data tool
Get electricity prices for the North West region for today. Identify the cheapest four-hour window and the most expensive period, and recommend when I should charge my EV.
Tips for Claude
- Ask for tomorrow's forecast prices the evening before to plan the next day's schedule
- Compare your current tariff rate against the live wholesale price to understand your margin
- Ask Claude to set a simple rule: "tell me if prices drop below X pence per kWh today"
ChatGPT presents electricity pricing as structured daily schedules and written summaries, making it easy to produce energy cost reports, advise tenants on bill reduction, or create briefings for building management teams. It adds the explanatory layer that transforms raw price data into actionable guidance.

How to check live electricity prices by region with ChatGPT
Once connected (see setup above), use the Energy Data tool:
- Ask: "Get electricity prices for the London region for today using energy-data"
- ChatGPT returns a full day's pricing schedule
- Request: "Format this as a table showing cheap, medium, and expensive periods"
- Follow up: "Write a brief energy-saving tip sheet based on today's price pattern"
Example prompt for ChatGPT
Try this with ChatGPT using the Energy Data tool
Pull electricity prices for the East Midlands for today and tomorrow. Identify the best times to run energy-intensive appliances and write a practical daily energy schedule.
Tips for ChatGPT
- Ask for a traffic-light summary (green/amber/red by hour) for quick visual scanning
- Request a comparison between today's prices and a typical day to spot unusual patterns
- Use this to produce weekly energy briefings for building management or tenants
Copilot brings live electricity pricing into your development environment, making it straightforward to build smart scheduling features, energy cost calculators, and demand-response integrations. The structured half-hourly data maps directly to time-series charts and scheduling logic without additional transformation.

How to check live electricity prices by region with Copilot
Once connected (see setup above), use the Energy Data tool:
- In Copilot Chat: "Get electricity prices for the South East region for today using energy-data"
- Copilot returns structured half-hourly price data
- Ask: "Write a function that finds the lowest-cost N consecutive hours in this dataset"
- Request: "Generate a TypeScript interface for the electricity price response"
Example prompt for Copilot
Try this with Copilot using the Energy Data tool
Fetch electricity prices for Yorkshire for the next 24 hours and return as a JSON array with timestamps and pence-per-kWh values, ready to feed a scheduling algorithm.
Tips for Copilot
- Build a "find cheapest window" helper function and reuse it across all scheduling features
- Cache prices with a 30-minute TTL to avoid redundant API calls in your application
- Use half-hourly timestamps as keys to align price data with smart meter readings
OpenClaw automates electricity price collection across multiple regions on a scheduled basis, feeding energy management systems, demand-response platforms, and cost analysis pipelines with consistent, timely data without manual intervention.
