Note: (1) risk of blackouts at the end of the 90s, (2) problems in planning (wrong projections of electricity demand), (3) cheap and easy financing, (4) the economic boom led to a considerable growth in demand, (5) positive signals by the government for investments in renewable energy, (6) positive signals by the government for investments in CCGTs, (7) easy granting of administrative permits by the regions (AACC), and (8) overcapacity is an inherent problem for electricity systems with a high RES penetration.
