ENTSOG Southern Corridor (SC) Gas Regional Investment Plan (GRIP) 2014-2023 / Main Report
Indeed, a sustainable and reliable growth of green electricity sources is heavily dependent on the back-up solutions put in place to substitute the renewable electricity streams when wind is not blowing or sun not shining. As natural gas is the fossil fuel having the least impact in terms of CO ² emission, CCGTs represent the most appropriate solution to fulfil RES back-up function without running the risk to waste the environmental gain provided by green energy sources. The situation in several selected countries is presented below.
3.5.1 GREECE RENEWABLES
In Greece the renewables have an important share in power generation, about 14.1% (2012), with hydropower being the most important. The share of renewables in power generation is expected to reach 29.6% by 2023 and, according to the forecast, wind and solar will contribute most to this increase. The difference between the historical value in 2012 and the forecasted value in

Figure 3.13: Power generation of Greece by source (historical and forecast)
Figure 3.14: Forecast of power generation in Greece from Renewable Energy sources from 2009 to 2012
2023 is 9,093GWh which is more than 240%. If we compare this increase with the difference between the historical and forecasted power generation figures for Greece (Figure 3.13) it results that the renewables can provide the additional power gener- ation demand for the next 10 years.
