China sheds light on transition to subsidy-free solar

An emphasis on grid-parity PV has been hammered out in the latest policy document to emerge after several weeks of haggling in Beijing. Chinese analyst AECEA says the success of the subsidy-free effort will hinge on the ability of power companies to transmit and guarantee consumption of the power generated by new projects.

China’s National Energy Administration (NEA) has given the broadest hint yet of its likely roadmap for the transition to ‘grid-parity’ solar.

The Work Plan for the Construction of Unsubsidized (Grid-Parity) Projects for Wind & Solar PV consultation paper released by the NEA yesterday is the latest document to emerge from weeks of negotiations between the Beijing authorities and solar industry stakeholders in the Chinese capital.

The emphasis on prioritizing PV projects that operate without central subsidies is clear is the document, with the NEA still making only vague noises about its intent to establish a national bidding process to permit subsidized schemes “in the months ahead”, according to Chinese consultancy AECEA, which has reported the contents of the consultation paper.

According to AECEA, the paper posits a freeze on bidding rounds for subsidized PV projects until the first batch of unsubsidized schemes is dealt with. Under the terms of the consultation paper – which would govern policy until the end of next year, to run alongside China’s 13th Five-year Plan – details of the first round of unsubsidized ‘grid-parity’ schemes would have to be submitted to national authorities by April 25.

Abolish or reapply

When that deadline expires, in two weeks’ time, priority would be given to historic projects which were secured in the expectation of FIT payments but which opt to become grid-parity facilities. After those, new grid-parity schemes would be considered and subsidized projects would be given “last” priority, reported AECEA. Details of subsidized PV projects would have a deadline of May 31 for submission to the authorities.

Projects which have yet to start construction two years after securing approval – or within any previously agreed extension period – must either resubmit their bid applications under the new regime or be abolished under the consultation paper, with AECEA estimating 7.8 GW of such projects would face that decision under the quota system plus a further 32 GW of capacity outside the quota.

AECEA states the success of a grid-parity policy push would hinge on the ability of China’s state-owned grid companies – the State Grid Corporation and the China Southern Power Grid Corporation – to guarantee transmission and consumption of all the solar power generated by subsidy-free projects under PPAs of at least 20-year durations, a commitment they and other grid operators are bound to according to the consultation paper.

Transition period

The analysts also report the document states the NEA intends to finalize details of its previously trailed green electricity certificate program by the end of June. The renewable obligation scheme has been highlighted by some analysts as another key factor in the push for grid parity solar.

AECEA warns the disruptive nature of the potential new policy would make it impossible to reliably estimate how much solar capacity will be added in China this year, with current estimates hovering around the 40 GW mark. The analyst states the consultation paper stakes out the territory for a Chinese solar market comprising grid-parity and subsidized PV until the end of next year, ahead of a hoped-for subsidy-free marketplace from 2021 onwards.
