System operators may also choose to have the electricity generated from renewable energy sources promoted by bonus payments at a statutorily set level per MWh (Clause 1.1. Price Resolution by the Energy Regulatory Office No. 2/2010).

Operators of systems for the generation of electricity from renewable energy sources are paid this bonus on top of the normal market price for electricity. Operators of systems generating renewable electricity for auxiliary consumption only are also entitled to the payment of this bonus (Chapter 2 § 4 Cl. 16 Act No. 180/2005 Coll.).

From 1 March 2011, the tariff will only apply to roof-top and wall-mounted photovoltaic systems with a capacity of up to 30 kW (from 1 March 2011: Chapter 1 § 3 Cl. 5 Act No. 180/2005 Coll.).

The level of the bonus is exclusive of VAT and is regulated according to the size of the system and the commissioning date. 4.5 – 13.66 CZK/kWh (approx. 18 – 55 cents/kWh) (Clause 1.9 Price Resolution by the Energy Regulatory Office No. 2/2010). The claim for payment is legally guaranteed for 20 years.

The Energy Regulation Office determines the Green Bonus for the following calendar year for the various different technologies used for the generation of electricity from renewable energy sources( Chapter 2 § 6 Cl. 1 Act No. 180/2005 Coll.). The Green Bonuses are adjusted annually to the Index for Industrial Production for existing systems.
