BRAZIL -- It's one of those stories everyone's talking about, at least in Brazil's wind energy space. And it should come as no surprise. Under its newly launched energy expansion plan, the government intends to boost installed wind power generation capacity to 11.5 GW by 2020 from a mere 1.5 GW now, bringing new and exciting investment opportunities for developers and entrepreneurs.
...According to Baitelo, the expansion is so aggressive that wind farms could very well overtake natural gas thermal plants as Brazil's second-power generation source in five years, moving right behind the number one source — hydroelectric power.
...She says a significant addition of 100-meter towers in recents years has sharply boosted windmill's generation/cost equation (as the new towers produce significantly more electricity) compared to the older facilities running on 50-meter towers.
She says some developers' plans to begin building 120-meter towers should boost productivity even more. At the same time, Melo claims Brazil has become the world's most coveted wind power market.
