"When politicians in berlin decide on the energy transition, nothing has happened yet. A frustrated eon employee expresses what many people are thinking in connection with the energy turnaround decided by the federal government at the drop of a hat. Although there is a precise timetable for decommissioning the last nuclear reactors, there is no timetable for how the missing electricity could be replaced. Example franconia: here, the grafenrheinfeld nuclear power plant is to be shut down on 31 december 2011.12.To be shut down in 2015.
Thuringian power bridge
Wind energy from the far north to replace nuclear power. As far as the plan. A route would be necessary, which transports the current from north to south. However, this does not yet exist. In concrete terms, we are talking about the so-called "thuringer strombrucke", to travel from halle/saale via redwitz to schweinfurt.
For this purpose, a new route must be built on the thuringian and partly also on the bavarian side. Planning, regional planning procedure, planning approval and finally the actual construction, all this takes time. It is therefore more than questionable whether the required route will be available at all when grafenrheinfeld is shut down in 2015. Insiders now believe that the thuringian electricity bridge will not be ready before 2017. Will the nuclear power plant then remain on the grid for longer??
Electricity purchase from abroad could become necessary
Rudolf boll, press spokesman for the federal network agency, points out that his agency decided in august 2011, in response to a request from the government, that there was no need for a longer operating time for any nuclear power plant. A statement, however, with which one wanted to commit oneself only up to the year 2013. And after that? Hours the routes to the verfugung, gives it no problems, so the lapidare bescheid. If not, instead of extending the term, it is also possible to temporarily obtain the missing electricity from abroad, for example from austria.
The time for the new construction of the line from thuringia towards redwitz, it could indeed be scarce. Three years have already passed since the energy line expansion act (enlag) was passed in 2009. During this time, only 214 kilometers, or just under twelve percent, of the required 1834 kilometers of transmission lines could be built. The federal network agency therefore realistically assumes that a large part of the enlag projects will be put into operation later than originally planned. 15 of the 24 projects are expected to be delayed between one and five years.
Tennet is responsible for the upper franconian section of the line to redwitz. Their press spokesman markus lieberknecht is optimistic. He thinks the timetable for completing the line by 2015 is ambitious, but feasible.
But only if everyone at the political level pulls in the same direction. What does not happen. Because thuringia's minister-president christine lieberknecht (CDU) has problems with citizens' initiatives that oppose the new route. Since her bavarian colleague horst seehofer (CSU) likes to talk about making bavaria self-sufficient in energy, she naturally likes to question the thuringian power bridge – because it is not needed then.
Eon wants to take gas-fired power plants off the grid
not very helpful, says the tennet spokesman. Especially since the line between redwitz and schweinfurt also has to be expanded. However, this is only about upgrading the existing 220 kv line to 380 kilovolts.
What if the schedule cannot be met? Then, in the event of the failure of grafenrheinfeld without replacement, the tension balance in the network could be disturbed, it says. A problem that had to be solved, if necessary, by diverting electricity via foreign countries.
Projects such as those of the energy supplier eon do not fit into the picture at all. Three gas-fired power plants in southern germany are to be shut down, including franconia I in nurnberg. The plants had too low an efficiency, were uneconomical.
This of course runs counter to the energy policy thinking that would like to replace the lack of nuclear power with renewable energy. Since this is not always possible in the event of darkness and no wind, gas-fired power plants have always played a central role in such considerations as a reserve source of energy.
An eon spokesman in dusseldorf denies that decisions have been made to shut down gas-fired power plants.
But: the company must of course pay attention to profitability. It is well known that the gas-fired power plant franken I, with an efficiency of just over 40 percent, is anything but economical. A closure is therefore said to have already been announced to the federal network agency.
The construction of new gas-fired power plants would remain. But: the current market conditions were not conducive to this, eon said.
