South Africa considers 5GW solar power park

CAPE TOWN (Reuters) - South Africa will test investor appetite this year for a solar park that could cost 150 billion rand and generate 5,000 megawatts of power, a government spokesman said on Thursday.
Africa's largest economy is increasingly turning towards renewable energy sources to help plug a chronic power shortage and decrease its dependence on the coal-fired power stations that provide most of its electricity.
Initial projections showed the park (...) could start in 2012, depending on investor response, government spokesman Themba Maseko told journalists.
Maseko said a feasibility study by the Department of Energy and the U.S-based Clinton Climate Initiative, had identified Upington in the semi-arid Northern Cape region as a potential site.
"As soon as the feasibility study is completed...it would be presented to an investors conference to test the appetite of investors to actually support an initiative of this nature," Maseko said.
State-owned power utility Eskom (...) with the help of a World Bank loan, is developing a 100 MW concentrated solar power plant, estimated to cost about 7 billion rand, also in the Northern Cape region.

Curiosamente nunca é claro se os 5G são de potência instantânia máxima ou anual média estimada (ou qualquer outra).

Quando vejo estas notícias gostaria de fazer umas contas, mas sem essa informação a notícia não se pode interpretar.

Num local (Upington) cujo potencial é 1670kWh/W/ano, se for 5GW (que é o que está escrito) produziria 5GW x 1670GWh/GW/ano = 8350GWh/ano.
Se eles quisessem dizer 5GWh/ano, a potência instalada seria 5 GWh/ano / 1670GWh/GW/ano = 3MW.
Um investimento de 150x10^9 rand = 15x10^9 euros corresponderia a 3€/W no primeiro caso e 5000€/W no segundo. Claramente que o que está escrito está correcto.
