In November 2015, due to the undermining of power lines on the peninsula there began mass power outage in Crimea. Due to a variety of political reasons, the issue of energy supplies to Ukraine has not been fully resolved. Energy blockade of the Crimea is not profitable for Ukraine - it will cause an excess of electricity in existing plants, and following shutdown of some energy blocks, what is dangerous. Besides, Ukrainian nuclear power plants purchase fuel from Russia.
On the other hand, the supporters of the blockade and the complicated relations between the two countries can again undermine this cooperation. Thus, the Crimea faces a necessity of self-sufficiency in electricity.
Russia has launched a power line of 400 MW with the total demand of about 900 MW. By the summer of 2016 they plan to launch the second branch.
However, even the supply of Russian energy in the Crimea does not fully satisfy the peninsula energy needs. Due to the presence of a large number of places not connected to a common power supply system, there is the need to introduce alternative energy sources.
In Crimea there are 7 wind power plants with a total capacity of more than 75 MBt. In 2010-2012. 4 was constructed solar power plants with total capacity of up to 223.7 MBt. In 2015, new "Nikolaevka" solar plant was also put into operation. This means that part of the Crimea can cover some of its energy needs by means of renewable energy sources.
However, the existing solar and wind stations have become not profitable because of the change in tariffs - earlier they were based on the Ukrainian green energy laws, and after the annexation to Russia have come under the Russian laws accordingly. It shows the need for Russia to prepare the legal framework to encourage the development of renewable energy in the region.
Nevertheless, these green power plants can solve an issue of power supply in small coastal regions.
