A microgrid is a localized energy system that can operate connected to the main grid or independently. It integrates distributed generation (solar, wind, gas turbines), storage systems (BESS), and demand-response tools.
The Cost Landscape: Industrial Electricity in Spain
For electro-intensive consumers in Spain, the effective cost is approximately €59.37/MWh after compensations and subsidies.
LCOE of Microgrids
Assuming a 20MW data center microgrid: weighted average LCOE ~€58-60/MWh, putting microgrids at parity with Spain's electro-intensive tariff.
Why This Matters for Data Centers
- Cost predictability: Lock in LCOE for 15-20 years
- Resilience: Independence from grid congestion
- Green positioning: Reduce Scope 2 emissions
- Regional advantage: Additional layer of cost optimization
