ENGAGEMENT OF BIOMASS CHP FOR POWER GRID BALANCING IN UKRAINE

Work is aimed on determination of possibilities of biomass CHP engagement for power grid balancing in Ukraine. The principal technical possibility for biomass CHP (existing and greenfield construction) engagement for balancing is considered and confirmed. The technical concept for biomass CHP switch from baseload regime into balancing regime has been developed. For effective operation on the peak load market, the existing biomass CHP shall be additionally equipped with boiler and turbine of higher capacity to provide possibility of additional peak electricity supply to the grid. As one of the possible decisions for stimulation of biomass CHP/TPP operation in balancing regime, the mechanism for provision of incentive tariff for peak hours (morning and evening peaks) has been proposed. According to the calculation, the respective incentive tariff to stimulate biomass CHP investor for balancing operation shall be 0.273-0.279 EUR/kWh depending on the electricity supply scheme and for the ratio between balancing and baseload capacities as 6/3. It was demonstrated, that for more large-scale projects and for smaller ratio between balancing and baseload capacities, the respective tariff will be lower.
