# WeSwitch Energy

> WeSwitch Energy (weswitch.energy) is an independent electricity comparison and switching service for residents, expats, and businesses in Spain. We help users compare electricity tariffs, upload their bills for AI-powered analysis, switch to cheaper providers, and find the best solar and EV-friendly energy plans. Available in English, Spanish, French, Dutch, Norwegian, and Swedish.

## About

WeSwitch Energy was created to solve a common problem: electricity bills in Spain are confusing, and most people—especially expats—overpay. We offer a free, independent comparison service that analyses your real electricity bill against every available tariff in the Spanish market. We are not an energy provider—we are an impartial adviser that earns commission only when we save you money by switching.

The site is multilingual. All pages are available under a locale prefix: `/en/`, `/es/`, `/fr/`, `/nl/`, `/no/`, `/sv/`. The English locale is the default.

## Core Features

- **Tariff Comparison Engine**: Real-time comparison of fixed and variable electricity tariffs from all major Spanish providers (Iberdrola, Endesa, Naturgy, Repsol, TotalEnergies, Octopus Energy, etc.).
- **Provider Switching**: End-to-end switching support—we handle the paperwork to move users to a better tariff.
- **Solar Tariff Analysis**: Specialised analysis for solar panel owners to find tariffs that maximise self-consumption value and surplus export compensation.

These are among the most detailed English-language resources available for Spain's electricity system.
- **Energy Newsletter & Industry News**: A regularly updated newsletter with articles on tariff changes, VAT and regulatory updates, wholesale price movements, renewable energy trends, and timely advice (e.g., how geopolitical events affect energy prices in Spain).
