Your EnergyVision bill consists of a fixed and a variable part. Each year, you receive 1,000 kWh of green electricity at a fixed price, which remains the same for 10 years. But how do we distribute these 1,000 kWh, and how can you make the most of them? We’re happy to explain.
How do we distribute the 1,000 kWh of green electricity?
This electricity comes directly from our local solar energy production. We spread the 1,000 kWh over 12 months based on the synthetic (solar) production profile (SPP). This means that you receive a larger share in the sunny summer months and a smaller share in the darker winter months when the sun shines less. This way, your consumption is optimally aligned with the natural production of solar energy. The table below shows exactly how we calculate the monthly distribution.
Month | Average solar energy (SPP) | 1.000 kWh from the sun |
January | 2,0082 % | 20,082 kWh |
February | 4,3071 % | 43,071 kWh |
March | 8,4879 % | 84,879 kWh |
April | 11,5057 % | 115,057 kWh |
May | 13,9814 % | 139,814 kWh |
June | 14,0998 % | 140,998 kWh |
July | 13,8771 % | 138,771 kWh |
August | 12,1248 % | 121,248 kWh |
September | 9,1899 % | 91,899 kWh |
October | 6,1864 % | 61,864 kWh |
November | 2,8930 % | 28,930 kWh |
December | 1,3387 % | 13,387 kWh |
Total | 100,00 % | 1.000 kWh |
At the end of last year, the Flemish Utility Regulator (VREG) approved these percentages for 2025.
How to use this green electricity smartly?
Since your 1,000 kWh comes from solar energy, it is best to plan your electricity consumption mainly during the day, when the sun generates the most energy. Good to know: this fixed rate does not apply to electricity consumed during the night rate, as the sun does not generate energy at that time. By timing your energy use wisely, you can maximize the benefits of your contract.
Customer for less than a year? Here’s how it works!
We distribute the 1,000 kWh over 12 months. If your billing period is shorter, we calculate your share based on the solar production profile.
What will change from August 1, 2025?
We’re bringing more of our sunshine to you, at a fixed price!
As of August 1, 2025, we are slightly adjusting our tariff structure. This allows us to provide you with even more energy from our own solar parks, at the advantageous fixed price of 9 cents per kWh.
What exactly is changing?
We’re switching to a new distribution of solar hours: no longer just on weekdays, but now 7 days a week. This means we can allocate more solar energy to your weekend consumption, even if that’s registered on your night meter.
What does this mean for you?
If you have a day/night meter and use more energy during the weekend, a larger portion of that electricity will now be billed at the favorable fixed price. If you have a 24-hour meter, you won’t notice any difference.
Why this change?
We want to make maximum use of our own solar production and deliver it directly to you as much as possible. Thanks to this change, we can guarantee more of that solar power at a fixed, attractive price, without you needing to do anything.
