As centrais nucleares são essenciais na competitividade da UE |
O estudo, que será divulgado em Dezembro, construiu cinco cenário de mix energético e concluiu (realces meus):
Of the five scenarios examined, the highest electricity prices are forecast in a “high renewables” scenario which envisages more supply of North Sea off-shore wind plus “significant” concentrated solar power – plants that concentrate the sun’s rays to produce steam and drive a turbine – and micro power generation from solar and wind.
Average electricity prices for households and businesses would rise “strongly up to 2020-2030” under all scenarios, the document says, and the highest prices would occur after 2030 if renewable sources of power, such as wind and solar, make up a large share of energy production. For example, average prices for households could jump by more than 100 per cent by 2050 if this were the case but only by 43 per cent under a scenario that assumed more nuclear power and carbon capture and storage were used.
The report suggests this would be partly due to new infrastructure investments but it also appears to assume that conventional fuel plants would not run as much as they do now, meaning higher prices would have to be charged to cover initial investment costs.Em Portugal este fenómeno motiva a existência de CMECs. O relatório europeu tem o bom senso de admitir que é por causa das renováveis que a produção termoeléctrica trabalha menos horas e por isso tem de ser paga para estar disponível. A APREN e a imprensa nacional pró-renovável acham que não.
Nos EUA o EPRI já tinha chegado à mesma óbvia conclusão há anos. Fiz eco disso há já mais de 2 anos, aqui:
