FMI Weather + Fingrid Wind/Solar Nowcast Feed (itulo/fmi-fingrid-nowcast)

Hourly joined feature feed combining Finnish Meteorological Institute (FMI) WFS point weather forecasts across Finland's primary wind, solar, and demand hubs (Oulu, Vaasa, Pori, Helsinki, Lappeenranta) with Fingrid Open Data wind generation forecast (245), solar generation forecast (248), electricity consumption forecast (166), and actual wind generation (75).

Ships as both a Pay-Per-Event Apify Actor (itulo/fmi-fingrid-nowcast) and an open-source stdio MCP Server (src/mcp-server.js).

Independent Tool Notice: Not affiliated with or endorsed by Fingrid Oyj or Ilmatieteen laitos (FMI). Uses zero Nord Pool or ENTSO-E day-ahead electricity exchange price data.

Built for EV Smart-Charging, Home Automation & Nordic Energy Analytics

• EV Smart-Charging Windows (isEvChargeRecommended): Ranks the next 36 hours by renewable share (windSolarSharePct) and low residual load (residualLoadMW) without relying on restricted power-exchange spot prices.
• Wind Hub & Storm Cut-Out Risk (fmiStormCutoutRisk): Weights Ostrobothnia & West Coast wind hubs (Oulu, Vaasa, Pori) and flags turbine storm cut-out risk when hub gusts approach 25 m/s.
• Demand-Weighted Heating Degree Hours (fmiHeatingDegreeHoursC): Computes hourly heating demand pressure across southern and northern population centers alongside 1-hour wind & residual load ramps (windRamp1hMW, residualRamp1hMW).

Connect to Claude Desktop, Cursor & MCP Clients (Model Context Protocol)

You can use itulo/fmi-fingrid-nowcast as a live tool inside Claude Desktop, Cursor, Windsurf, or any MCP-compatible AI agent in two ways:

Option A: Hosted Apify MCP Server (@apify/actors-mcp-server)

Zero local setup required. Add this to your claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json) or Cursor .cursor/mcp.json:

{
  "mcpServers": {
    "fmi-fingrid-nowcast": {
      "command": "npx",
      "args": [
        "-y",
        "@apify/actors-mcp-server",
        "--actors",
        "itulo/fmi-fingrid-nowcast"
      ],
      "env": {
        "APIFY_TOKEN": "YOUR_APIFY_API_TOKEN"
      }
    }
  }
}

Option B: Local Stdio MCP Server (Open-Source CLI)

Run the bundled stdio MCP server (src/mcp-server.js) directly on your machine. Exposed MCP tools: fmi_fingrid_nowcast, fmi_station_weather, fmi_fingrid_licence_info.

{
  "mcpServers": {
    "fmi-fingrid-nowcast-local": {
      "command": "node",
      "args": [
        "/absolute/path/to/tools/fmi-fingrid-nowcast/src/mcp-server.js"
      ],
      "env": {
        "FINGRID_API_KEY": "YOUR_FREE_FINGRID_API_KEY"
      }
    }
  }
}

n8n, Make.com & REST API Integration (One-Call Sync JSON)

Trigger itulo/fmi-fingrid-nowcast synchronously and get the normalized JSON dataset items back in a single HTTP request — ideal for n8n HTTP Request nodes, Make.com, Zapier, or cron webhooks:

• Method: POST
• Endpoint: https://api.apify.com/v2/acts/itulo~fmi-fingrid-nowcast/run-sync-get-dataset-items?token=YOUR_APIFY_API_TOKEN
• Headers: Content-Type: application/json

cURL Example

curl -s -X POST \
  "https://api.apify.com/v2/acts/itulo~fmi-fingrid-nowcast/run-sync-get-dataset-items?token=${APIFY_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"mode":"joined_nowcast","places":["Oulu","Vaasa","Pori","Helsinki","Lappeenranta"],"hoursBack":6,"hoursAhead":36,"topN":6,"includeStationBreakdown":false}'

Frequently Asked Questions (FAQ)

How does this actor combine FMI meteorological forecasts with Fingrid grid forecasts?

It fetches hourly HARMONIE-MEPS surface weather point forecasts from the Finnish Meteorological Institute (FMI WFS 2.0) across Finland’s primary wind, solar, and demand hubs (Oulu, Vaasa, Pori, Helsinki, Lappeenranta) and joins them by UTC hour with Fingrid Open Data wind generation forecast (245), solar forecast (248), consumption forecast (166), and 15-min actual wind generation (75).

What derived energy & EV smart-charging signals are included?

Each hourly record includes capacity-weighted hub wind speed (fmiWindSpeedWeightedMs), max hub wind gusts & storm cut-out risk (fmiStormCutoutRisk at >=25 m/s), demand-weighted temperature & heating degree hours (fmiHeatingDegreeHoursC), 1-hour wind and residual load ramps (windRamp1hMW, residualRamp1hMW), and an EV smart-charging recommendation rank (isEvChargeRecommended, nowcastScore).

Does weather_only mode work without a Fingrid API key?

Yes! Set mode: "weather_only" (or call the fmi_station_weather MCP tool) to run 100% keyless using only FMI WFS open data. For joined_nowcast or ev_charging_windows, pass your free fingridApiKey.
