Over Two Decades of Green Energy

Founded in 2000 in Barcelona, Nexus Energía initially focused on business and industrial clients before expanding into the residential market.

They pride themselves on supplying 100% renewable energy and supporting independent green energy producers across the Iberian Peninsula.

By 2026, they serve tens of thousands of residential customers, though their primary strength remains in the commercial sector where their custom pricing is more competitive.

What Customers Say About Nexus

300+ Verified Reviews

Reviews for Nexus are mixed. While many praise their green credentials and reliable business service, residential customers frequently note that their bills are higher than expected due to steep fixed capacity (potencia) charges.

What we like

  • 100% Certified green energy
  • Solid track record since 2000
  • Clear, simple tariff structures

What to watch for

  • Exceptionally high fixed power (potencia) prices
  • Customer service can be slow for residential clients
  • App is basic compared to modern competitors

Who should avoid Nexus Energía?

"Households with high contracted power (potencia) or very low energy usage, as the high daily fixed fees will erase any savings from the lower kWh price."

Editor's Note: Honest assessment for better matching.

Frequently Asked Questions

Why are Nexus Energía's power prices higher than average?

Nexus has structured their tariffs with a relatively low energy (kWh) price but offsets this with very high fixed capacity (€/kW/day) charges. This means even if you use very little electricity, your minimum monthly bill will remain quite high.

Does Nexus offer gas as well?

Yes, you can bundle your electricity with gas for a single bill, though their gas prices are often tied to standard market fluctuations.
