The Hellenic Association of Photovoltaic Companies has updated its investment guide for photovoltaics.
In its new revised edition, it includes the changes introduced by Laws 4819/2021 and 4821/2021, such as the submission of a “Producer Certificate Guarantee Letter”, changes in the signing of operating aid contracts, restrictions on the number of projects an investor may implement outside competitive procedures, special conditions for saturated grids, and more.
As stated in the introduction by the Hellenic Association of Photovoltaic Companies (HELAPCO), in recent years there has been a steadily increasing interest in photovoltaic investments and a revival of the market.
This is partly due to the fact that the investment cost of photovoltaics has dropped dramatically compared to the previous decade (a reduction of up to 80% on average). At the same time, the regulatory framework is continuously being adjusted to reflect this new reality.
Today, the available options vary depending on the type and scale of the investment one wishes to make. These options can be summarized as follows:
- Sale of the generated energy to the grid.
- With fixed prices per kilowatt-hour (for systems up to 500 kWp or 1 MWp, specifically for Energy Communities).
- Through participation in competitive procedures for systems with capacity greater than 500 kWp or 1 MWp, specifically for Energy Communities.
- Through direct participation in the wholesale markets of the Energy Exchange.
- Through the conclusion of private power purchase agreements (PPAs) with interested consumers (this option is expected to be practically utilized from 2022 onwards).
- Self-consumption of the generated energy.
- Self-generation with energy net metering (net metering).
- Self-generation with the option to sell up to 20% of the generated energy (applies to businesses).
- Real-time self-consumption with the sale of excess energy (this scheme is expected to be regulated within 2021).
