Abstract: Environmental concerns and technology development are driving power systems to a new stage where the increased penetration of renewable energy resources (RES) is replacing the conventional fossil fuel-based power plants. This transition brings the sustainable and ecological credentials but at the same time involves the major challenge
READ MOREAt present, renewables are cheaper than gas. A minimum cost of 69.05 £/MWh is found at a wind penetration of 57%. After this point, the TCoE starts to increase due to the increasing capex of the energy storage, which increases exponentially as the overall penetration of renewables approaches 100%.

READ MORESince 2002, the penetration of non-hydro renewables in supply have increased from only 2 percent to 22 percent in 2012. The bulk of generation from new renewables, as in Portugal, is from wind energy. In 2011, wind energy contributed more than 15 percent of supply; solar more than 3 percent; and biomass nearly 2 percent.
