Supply of reactive power and maintenance of reactive power reserves
The aim of the reactive power tariff is to guide the use of reactive power optimally, considering technical aspects such as transmission capacity. From 2016 onwards, the guideline for 'Supply of Reactive Power and Maintenance of Reactive Power Reserves' was reformed with regard to pricing and monitoring of reactive power.
Transition to the new pricing
The new pricing will be introduced gradually starting from the beginning of 2017:
- In 2017 for reactive power exceeding the reactive power limits, a third of the unit price will be charged (333 €/MVAr, month), reactive energy 5 €/MVArh.
- In 2018 for reactive power exceeding the reactive power limits, two thirds of the unit price will be charged (666 €/MVAr, month), reactive energy 5 €/MVArh.
- From 2019 onwards, for reactive power exceeding the reactive power limits, a unit price of 1000 €/MVAr, month and a reactive energy fee of 5 €/MVArh will be charged.
The fifty highest exceeding hours for each month are excluded in the invoicing of reactive power. If a power plant, with power exceeding 10 MW, is not used for local reactive power compensation, the impact of the power plant can be deducted from the connection point measurements.
The operation and maintenance of the reactive power is agreed in the Main Grid Contract 2016 Appendix 1 Main Grid Service Terms and Conditions and in the Reactive Power and Reactive Power Reserves.
Reactive power reserves
From 2016 onwards, the reactive power reserves are based on obligation. The operational and structural requirements for reactive power reserves are defined in detail in the Specifications for the Operational Performance of Power Generating Facilities (VJV2013).
