Net Billing: The New Energy Compensation System
An innovative approach to self-generation that revolutionizes how consumers interact with the electrical grid.
What is Net Billing?
Unlike traditional Net Metering, Net Billing focuses on financial compensation for the energy fed back into the grid, offering a more modern and flexible way to manage generated energy.
How It Works in 3 Steps
1. Energy Generation
The photovoltaic system generates electricity, directly covering part or all of your energy needs during daytime hours.
2. Offsetting & Injection
Excess energy not consumed immediately is automatically fed into the distribution grid (HEDNO / DEDDIE).
3. Financial Compensation
The consumer receives a credit/financial compensation for the energy injected, based on a predetermined market purchase price.
Advantages & Challenges
✨ Advantages
Cost Savings: Drastically reduces overall energy expenses.
Sustainability: Contributes to the green transition and carbon footprint reduction.
Flexibility & Autonomy: Offers greater control and energy independence.
⚠️ Challenges
Lower Rate: The selling price of surplus energy is often lower than retail purchase prices.
Regulatory Framework: Requires ongoing monitoring of legislative changes.
Net Billing vs Net Metering
The core differences between the new and older compensation frameworks (Law 5037/2023):
| Characteristic | Net Metering | Net Billing |
|---|---|---|
| Offsetting Method | Energy units are offset (kWh vs kWh). | Monetary value of energy is offset (€). |
| Compensation Rate | 1 kWh injected = 1 kWh retrieved (retail rate). | Wholesale rate, lower than retail price. |
| Surplus Management | Energy storage in the grid for up to 3 years. | Immediate injection with credit compensation. |
| Program Maturity | Older, more established framework. | New framework gradually replacing Net Metering. |
Virtual Net Billing
Allows the installation of a photovoltaic system in a remote location separate from the point of consumption. Established in Greece under Law 5037/2023.
Ideal for: Apartment buildings, businesses with leased premises, and energy communities.
🏢 Net Billing for Businesses
Businesses must prepare their technical studies and documentation to promptly submit applications through the HEDNO platforms.
🔹 Installation of bidirectional smart meters.
🔹 Net Billing contract with the electricity supplier.
🔹 Specialized technical sizing based on consumption profiles.
