An emergency ordinance set to go into effect 1 July and affecting production through 2016 will halve the green certificates issued to wind producers to one certificate per megawatt hour of production from a previous two.
The second green certificate will still be issued, but only beginning 1 January 2018. Details of delayed certificate payments, which will be made in steps through 2020, must still be settled by energy regulator ANRE.
The ordinance is widely seen as a response to industrial consumers' complaints the green certificate scheme was costing them too much.
Market players have been bracing themselves for negative legislative developments after a draft law began circulating which would have cut the maximum price for green certificates. The ordinance makes no mention of that.
Romania's installed wind capacity stands at about 2.1GW, nearly half of which began operating last year. The mood has soured this year, and new capacity is expected to fall short of the roughly 1GW initially expected.
