E.ON: boom in the development of photo-voltaic power plants and the need to balance the stability of the transmission and distribution network
In 2010, the Energy group E.ON is also supporting the connection of recoverable energy sources into its distribution network; however, it cannot satisfy all applications and continue to maintain the stability of the distribution network. E.ON responds to the call of the company ČEPS to stop the issuing of positive decisions to applications for the connection of new wind and photo-voltaic power plants applied for all required outputs. This does not concern sources which have been obligatorily approved for connection by our company.
During the last few days, the company E.ON Distribuce, a.s. received a request from the company ČEPS regarding the suspension of the issue of approval for applications for the connection of new wind and photo-voltaic power plants (VTE and FVE). According to the company ČEPS, the reason for this request is the exceeding of the safe limit of output of installed and already approved power plants which have been approved for the connection of their outputs into the electrification system of the Czech Republic. The connection of further production sources not approved by distribution companies may threaten the safe and reliable operation of the electrification system. Exceeding the safe limit would consequently require the disconnection of existing wind power plants and photo-voltaic power plants. The disconnection of these sources concerns their common operation, mainly to prevent the occurrence of a status of emergency in the electrification system.
In the past, the company E.ON Distribuce has declared several times its support for the connection of recoverable sources. It wants to contribute to the commitment of the Czech Republic towards EU Directives for an increase in the ratio of the production of energies from recoverable sources up to 13 % by 2020. Within the previous two years alone, the ratio of installed output of recoverable sources in the supplying territory of the company E.ON Distribuce increased 100 times from 7 MW (in 2008) to an expected total of 750 MW (in 2010). The enormous interest of investors in fast connection of this renewable energy, as well as other new recoverable sources (mainly FVE), at present significantly exceeds the transmission possibilities of the distribution system of the company E.ON and threatens the safe and reliable operation of the system. After performing a detailed analysis of the status of the connection of wind power plant and photo-voltaic power plants, the management of the company decided, with immediate validity, to satisfy the request of the company ČEPS. "This decision was supported by the fact that since May last year we have had to gradually suspend the issue of consent for the connection of these sources in our distribution territory in cases when the investor requires connection of a source with an output higher than 250 kW," stated the spokesperson of the company, Vladimír Vácha.
"We share the opinion of the company ČEPS that further connection of the above-mentioned facilities would threaten the stability and safety of deliveries in the whole distribution network in the Czech Republic and the distribution network of the company E.ON Distribuce, a. s.," added Vladimír Vácha.
Further details will be published on the Internet pages of the company E.ON Distribuce, a. s. and on the pages of the company ČEPS.
The E.ON energy group in the Czech Republic belongs to the group E.ON Energie AG. E.ON Energie AG is the largest private provider of energy services in Europe, and supplies electricity and gas for about 15 million customers. Czech energy group E.ON supplies electricity in South Bohemia and South Moravia for 1,4 million customers and has achieved the market share of about 20 %. In the gas area, it has a more than 4.000 km long network, and supplies gas for 110.000 customers in South Bohemia.
