An intensive development of the use of wind and solar power threatens the stability of the Czech power grid. Recent projects to develop wind and solar energy have been approved by the authorities of the Czech Republic. However, the main distributors of energy, power generation capacity in the latter is four times what the country’s electricity grid could integrate safely.
The Czech Association of regulating societies electro-energy (CSRE) has pointed out that the effect of the total installed capacity of these projects amounted to 8063 MW (noting that the gap between actual output and installed capacity of such projects is potentially broad, as subject to the vagaries weather), and that the operators had already signed framework contracts for the connection of these new energy sources to the network to nearly 2,352 MW of installed capacity. In this context, the association has expressed concern, saying that the Czech power grid could integrate more than 1,650 MW by 2012, approximately 2,200 MW of installed capacity. Petr Zeman, Director General of the operator CEPS and a member of the CSRE, has asked the legislature to act quickly or risk having to manage network congestion by 2011.
‘s generous feed-in tariffs Solar energy has also caused an intensive development of the sector that threatens traditional retailers, in particular hydropower. But according to Mr. Zeman, it is vital to maintain large reserves of conventional energy sources to balance the distribution system grid and to be able to offset the volatility and crashes in the production of renewable energy.
Mr. Martin Roman, CEO of the company CEZ, also reported that rates of energy were highly overvalued and castigates the feed-in tariffs for solar power, arguing that the costs to consumers could s’ raise nearly 50 billion euros over the next 20 years.
