"The prices for balance and non-balance are almost equal. They are higher than the revenue that is available from the power plants - a new methodology of the Energy and Water Regulatory Commission, introduced on May 1," explained Velin Bogdanov of the National Association of PV Plant Owners, which is organizing the national protest. In his words, the most vulnerable are the owners of small plants and almost all of them are facing bankruptcy.

The protesters have vowed to take their protest to the Energy and Water Regulatory Commission if there is no solution to the problem. "If this does not end, everyone will go bankrupt in three months," Velin Bogdanov added.
