Reserves for new cogeneration

Two reserves for cogeneration are formed and, which are part of the reserve for new entrants for each year of the period.

– reserve of allowances for emissions from power generation of new natural gas cogeneration.

– reserve of allowances for emissions from generation of heating from new entrants with cogeneration in the scheme. It reflects the transformation of an installation with thermal power below 20 MW in a cogeneration with thermal power over 20 MW, and it is included in the trading scheme.

The volume shows total emissions in the country from electric energy generation of new natural gas cogeneration and increases the emissions in the cogeneration sector. The increase is determined on the basis of expected production of electric energy from a new cogeneration with an emission factor 0,33 t CO₂/MWh. This factor is applied in case the conditions (fuel consumption) for heat generation remain the same after the introduction of the cogeneration. The purpose of this reserve is to promote Government’s policy on support of effective cogeneration.

The volume of – is equal to the volume of emissions form heating generation of new entrants with cogeneration in the scheme, which will transform a heat installation with thermal power under 20 MW into a cogeneration with thermal power over 20 MW, and this way it is included in the scheme. This reserve is neutral regarding the overall emissions for the country. It increases allowances available in the sector cogeneration for new entrants in the scheme and reduces, by the same quantity, the emissions in the group of non-participants.

The volume of the reserves is determined on the basis of Bulgaria’s targets regarding introduction of new highly effective cogeneration. For a target of 18% , the reserve is determined as the difference between forecasted and target production of electric energy is multiplied by an emission factor 0,33 t CO₂/MWh. The quantity of allowances for heat generation installations of below 20 MW power is set to 20% of the allowances allocated to the production of electric energy.
