Energy Data — Solar estimates and live electricity prices worldwide

Tools / Energy Data

Electricity Prices

Get current electricity prices for any location. Auto-detects region and queries the best source: UK (half-hourly), EU (day-ahead, 40+ countries), Australia (real-time spot), or US (monthly retail by state).

Returns: Current electricity prices from the best regional source — consumer and/or wholesale rates with time series

Parameters

latitude *numberLatitude of the location (-90 to 90)

longitude *numberLongitude of the location (-180 to 180)

Example

Electricity prices in London

curl -H "Authorization: Bearer $TOOLROUTER_API_KEY" \
  -d '{
  "tool": "energy-data",
  "skill": "electricity_prices",
  "input": {
    "latitude": 51.5074,
    "longitude": -0.1278
  }
}' \

Solar Estimate

Estimate solar energy production for any location worldwide. Returns annual and monthly kWh output, solar radiation, capacity factor, and nearest weather station details.

Returns: Annual and monthly solar energy production (kWh), solar radiation, capacity factor, and weather station info

Parameters

latitude *numberLatitude of the location (-90 to 90)

longitude *numberLongitude of the location (-180 to 180)

system_capacity_kwnumberSystem size in kilowatts (default: 4)

module_typestringSolar module type (default: standard)

roof_mountbooleanRoof-mounted (true) or open rack (false). Default: true

tilt_degreesnumberPanel tilt angle in degrees (default: 20)

azimuth_degreesnumberPanel azimuth (180 = south-facing, default: 180)

Example

Solar estimate for a 4kW system in Denver

curl -H "Authorization: Bearer $TOOLROUTER_API_KEY" \
  -d '{
  "tool": "energy-data",
  "skill": "solar_estimate",
  "input": {
    "latitude": 39.74,
    "longitude": -105,
    "system_capacity_kw": 4
  }

Frequently Asked Questions

Does Energy Data work worldwide or only in a few markets?

Solar estimates work globally. Electricity price coverage is regional: UK half-hourly pricing, EU day-ahead pricing, Australian real-time spot pricing, and US state-level retail pricing.

What do I need to provide for an electricity price lookup?

You pass latitude and longitude. The tool uses those coordinates to detect the best regional data source automatically, so you do not need to choose the market yourself.

What do I need to provide for a solar estimate?

Start with latitude and longitude, then optionally tune the system size, module type, roof mount, tilt, and azimuth. If you omit the advanced settings, the tool uses sensible defaults.

Can I use it to estimate solar savings, not just production?

Yes. A common workflow is to estimate annual solar output with `solar_estimate`, then combine that annual kWh figure with local electricity pricing to estimate value or savings.
