Two scenarios with different reduction target have been examined: higher ambition scenario where emissions are restricted to 10% above 1990 levels in 2021 and 2.5% in 2030, and moderate ambition scenario where emissions are restricted to 25% above 1990 levels in 2021 and 15% in 2030. In order to provide insights into the optimal timing of emission reductions, both of these cases have also been run under cumulative constraints, that is, rather than having the specified annual targets, there is a carbon “budget” set for 2015–2030 (44Mt and 26Mt for higher and moderate ambition cases, respectively), reflecting the same ambition as the above cases but providing flexibility to reduce emissions in the most cost-optimal way. The results show that most of the CO2 reductions are in the power generation sector, which is not surprising as this tends to be the most carbon intensive sector. The higher ambition case is considerably more expensive than the reference case, with costs 1.9% higher, while the increase under the moderate ambition case is 1%. Under a cumulative constraint, the additional costs are reduced to 1.5% and 0.6% respectively, highlighting the importance of the timing of action.

The implementation of the adopted feed-in tariffs is discussed taking into account the proposed installed capacity limits, level and duration of support for the RES plants, system costs, market prices and the overall impact on the Macedonian

The objective of CoolHeating was to support the implementation of "small modular renewable heating and cooling grids" for communities in South-Eastern Europe. CoolHeating transferred knowledge from partners in countries where renewable district heating and cooling examples exist (Austria, Denmark, Germany) to countries where there are less examples in the sector (Croatia, Slovenia, Macedonia, Serbia, Bosnia-Herzegovina). Core activities, besides techno-economical assessments, included measures to stimulate the interest of communities and citizens to set-up renewable district heating systems as well as the capacity building about financing and business models. The outcome was the initiation of new small renewable district heating and cooling grids in 5 target communities up to the investment stage.
