Can You Sell Electricity Back to the Grid in Portugal?
If you’re an international homeowner in the Algarve, either living there permanently or managing a holiday property, you may be wondering if you can sell surplus solar energy back to Portugal’s electricity grid. The answer is yes—you can sell any excess energy and contribute to the grid while lowering your energy costs. Here’s a guide on setting up a self-consumption system that lets you produce, consume, and even sell solar power back to the grid.
Step-by-Step Guide to Sell Electricity Back to the Grid in Portugal
Setting up a solar system in Portugal that enables you to sell electricity back to the grid involves a few important steps to ensure compliance with regulatory standards:
Step 1: Determine Your Profile
Identify your energy profile and what you aim to achieve with the solar system. Decide if you want to produce electricity just for personal use or if you also want to inject surplus energy into the grid.
Step 2: Consult with an Authorized Technician
Work with a licensed technician to design and install your system. They’ll help you select the right equipment and navigate the registration process. For convenience, check the list of accredited technicians on the DGEG website, or consult our team at Voltaicos.
Step 3: Register on the DGEG Self-Consumption Portal
If your installation exceeds 700W or you wish to sell electricity back to the grid, register on the DGEG Self-Consumption Portal. You’ll need:
- Your Point of Delivery Code from your electricity bill
- Your NIF Number (tax identification)
- Installation details, including the authorized technician’s information
Step 4: E-REDES Analyzes Your Request
After you register, E-REDES will assess the setup. If the requirements are met, they’ll approve the application and provide a link to track the installation’s progress.
Step 5: Meter Verification by E-REDES
E-REDES will inspect your meter to ensure it’s suitable for tracking both consumption and surplus. If upgrades are necessary, they’ll handle it at no additional cost.
Step 6: Certify Your Installation for Large Systems
For systems over 30kW, certification by the DGEG is required, which involves an inspection to ensure compliance with national standards.
Step 7: Start Consuming and Sell electricity back to the grid in Portugal
With certification complete, you can begin consuming the energy you produce and selling any excess to the grid. Use the Production Point of Delivery Code (CPE) provided by E-REDES to manage and track your contributions.
Step 8: Monitor Your System Using the E-REDES Digital Counter
The E-REDES Digital Counter and app let you track your energy production and grid contributions, so you can stay on top of usage and earnings.
How Much Can You Earn from Selling Electricity Back to the Grid in Portugal?
The rate to sell electricity back to the grid in Portugal can reach up to €0.08 per kWh. Although this rate varies based on contract terms and grid demand, it provides an effective way to offset energy costs. The income you receive depends on several factors:
- System Size: Larger systems can generate more surplus energy, increasing potential earnings.
- Household Consumption: The less energy you use, the more surplus you have to sell.
- Seasonal Production: Sunny months, especially in the Algarve, generate higher output, boosting potential returns.
Selling back to the grid lets you maximize your solar system’s value and contribute clean energy to Portugal’s grid, benefitting both your budget and the environment.
