The council's documents show the Latvian company submitted a preliminary non-binding electricity purchase-sale contract signed with Baltiyskaya AES, an enterprise established by Russia's Rosenergoatom, which built the nuclear power plant in Kaliningrad.
The construction was halted in May, 2013 after more than a fifth of the work was completed. Baltiyskaya AES says it sells electricity.
The Russian news agency Interfax reported in July that Rosenergoatom planned to conserved the unfinished nuclear facility and allocate 0.464 billion roubles for the purpose this year.
