A difficult puzzle is called upon to solve the RIS for its industry green energythat is to say investors in RES and storage.
The most important problem is so -called cannibalism, that is, the more the installation of photovoltaics is enhanced, the more their economic viability decreases. Now, energy storage comes to solve the problem of lost green production at noon, but she also has the same problem. As storage units are installed in our country, the revenue of the electricity market will be reduced. The reason is simple: the price difference between noon and evening, on which they are based to make profits will be constantly reduced. When this difference falls below a point, then investments are now unprofitable.
As a result, we reach a paradox: that more storage heals photovoltaics, but damages the same and vice versa more photovoltaics heal storage, but harm themselves.
The solution for the dilemma is to secure revenue for projects outside the electricity market. But as the RIS is no longer willing to offer subsidies, the only choice left is the so -called bilateral contracts. Producers and consumers conclude agreements on predetermined quantities and a specific price over a long time.
However, the development of bilateral contracts is still lagging behind in our country, which was raised by producers and industries at a conference held yesterday. In any case, it is a complex tool with high technical and legal costs.
A second idea that has fallen on the table is to provide the state guarantees for the projects, but to date it has not progressed.
NTUA Professor Pantelis Capros, who is head of the workshop that develops EU computing models. In action, he warned by saying:
“If there is no serious green portfolio support program with guarantees, and not with a subsidy, then it will fall out and we will have overturns.”
