At its third-quarter press convention on 31 July, China’s Nationwide Vitality Administration (NEA) launched a collection of statistics on the ability sector’s 2024 efficiency thus far. One standout determine was the 486 million Inexperienced Electrical energy Certificates (GECs) issued through the first half of the 12 months – a 13-fold improve in comparison with the identical interval final 12 months.
This indicators progress in the direction of the decarbonisation and reform of the ability sector, however such a steep improve in issuances additionally presents administrative challenges: policymakers should now guarantee every GEC is rigorously verified and genuinely displays clear vitality going into the grid.
Every GEC represents 1,000 kWh of renewable vitality. Because the buying and selling scheme started in 2017, 707 million of those digital certificates have been issued. Through the first half of 2024, extra GECs have been created than within the earlier 6.5 years mixed.
The scheme allows renewable vitality turbines to complement their income by promoting GECs, and shoppers to fulfill their compliance or voluntary decarbonisation targets. In China, GECs are the solely technique to show that electrical energy is from a renewable supply. Because the nation strikes to extend its consumption of renewable vitality, GECs have gotten a highly effective accounting instrument for the market.

As inexperienced energy initiatives are pressured into market buying and selling, photo voltaic initiatives may see very weak economics, and perhaps the one factor helpful about their energy is that it’s inexperienced.

Worth discovering within the GEC market
In keeping with Anders Hove, a senior analysis fellow on the Oxford Institute for Vitality Research, this 12 months’s dramatic improve in GEC issuances stems from an NEA coverage activated in August 2023, which expanded the scope of eligible initiatives. It has enabled distributed renewables, offshore wind, and biomass technology corporations to promote GECs. They be a part of large-scale wind and photo voltaic suppliers, which have been included within the scheme since 2017.
Along with issuances, GEC gross sales additionally ballooned over the primary half of the 12 months, although not on the similar price. In keeping with China Electrical energy Council information, 187 million GECs have been traded within the first 5 months of 2024 – a 327 per cent year-on-year improve.
Sharon Feng, managing marketing consultant of China energy market analysis at Wooden Mackenzie, attributes this rising demand to the Chinese language corporations going through worldwide stress to decarbonise in addition to the Chinese language authorities’s push to fulfill the home renewable energy consumption goal.
“Worldwide corporations require their Chinese language operations and provide chains to buy inexperienced energy to fulfill company web zero targets,” Feng explains.
Low costs are additionally contributing to rising GEC gross sales. Presently, GEC provide is outpacing demand, as seen within the disparity between the 486 million GECs issued and the 187 million traded. This imbalance has led to a drop in costs: within the first half of 2023, they ranged from CNY 30-50 (USD 4.25-7.1), however by July 2024, that they had fallen to CNY 1-10.
The August 2023 coverage additionally performed a job in reducing costs. Earlier than then, renewable electrical energy turbines promoting GECs needed to forgo central authorities subsidies. This resulted in a reluctance amongst turbines receiving subsidies to promote GECs for something lower than the subsidy worth.
In keeping with Hove, “earlier than August 2023, the value of GECs was unofficially tied to the subsidy worth. Adjusting that linkage has allowed the value of GECs to fluctuate and the outcome has been cheaper certificates”. This has additionally created a flood of GECs from turbines nonetheless receiving subsidies, which now have a brand new income.
That is a part of the market’s price-discovery course of, which displays rising liquidity. For instance, throughout China’s Labour Day vacation in early Might, GEC costs dipped beneath CNY 1 as factories shut down and electrical energy demand plummeted. Spot electrical energy costs in some areas turned unfavourable because of the noon energy surplus.
Detrimental pricing is a problem for turbines, but additionally an anticipated consequence of ongoing market reforms. As China liberalises its energy sector, unfavourable pricing will probably change into a standard characteristic in spot markets. In 2022, the NEA introduced that by 2030, all renewable vitality turbines should promote their electrical energy at market charges as a substitute of to utilities at fastened costs. This shift forces turbines to seek out methods to remain worthwhile at the same time as electrical energy costs decline with elevated renewable provide.
“Turbines must see a path to revenue so that they have an incentive to construct initiatives,” says David Fishman, a senior supervisor at vitality sector consultancy The Lantau Group. “As inexperienced energy initiatives are pressured into market buying and selling, photo voltaic initiatives may see very weak economics, and perhaps the one factor helpful about their energy is that it’s inexperienced.” On this context, GECs assist stabilise renewable vitality producers’ income streams.
Administrative challenges
Whereas GECs are a key element of a market-driven energy sector, the speedy improve in issuances has created administrative challenges. The NEA’s July assembly recognized points comparable to incorrect or duplicate functions, reflecting the pressure on regulatory oversight because the market grows.
The Chinese language media group Caixin has reported that worldwide recognition of GECs stays restricted, partly as a consequence of issues over double-counting.
Since 2012, Chinese language corporations have been capable of offset emissions utilizing China Licensed Emission Discount (CCER) credit, through initiatives like afforestation or renewable vitality technology. This overlap means the identical renewable challenge may obtain each CCERs and GECs. Because of this, CCERs have been suspended in 2017, the identical 12 months GEC issuance started, although China relaunched the CCER scheme in January this 12 months.
The danger of double-counting persists, nevertheless. Offshore wind initiatives, as an example, can obtain each GECs and CCERs, doubtlessly issuing two credit for a similar unit of fresh electrical energy.
In September, the Ministry of Ecology and Setting issued a coverage doc clarifying that offshore wind turbines who have been issued CCERs weren’t eligible to obtain GECs, and vice versa. Whereas there was no proof of double counting for offshore wind initiatives thus far, the priority stays.
“There’s nonetheless a legacy reputational drawback, stemming from these fears of issuing GECs and CCERs to the identical initiatives,” explains Fishman. “The variety of corporations purposefully double-counting is low, however the greater drawback is that the regulator hasn’t but issued a clearly worded coverage that stops double-counting.”
Policymakers should stability the necessity to stimulate the GEC market and promote renewable vitality improvement with the upholding of rigorous verification processes. That is particularly necessary as a result of most of the main purchasers of GECs are Chinese language corporations doing enterprise overseas – a scandal affecting GEC legitimacy may hurt their sustainability claims.
What’s subsequent for the GEC market?
Along with defending their credibility, one other GEC coverage aim appears to be increasing their function in supporting energy grid flexibility. A July discover introduced that pumped-storage hydropower (PSH) initiatives at the moment are eligible to challenge and commerce GECs. PSH shops extra renewable vitality by pumping water to greater elevations, releasing it to generate electrical energy when wanted.
This marks the primary time that energy-storage initiatives have been permitted to challenge GECs, breaking with worldwide norms. In China, GECs can solely be traded as soon as, that means impartial storage initiatives that buy inexperienced electrical energy can not resell the GECs after they promote saved energy.
“This limitation on secondary buying and selling is unlikely to alter; there appears to be no understanding of why secondary buying and selling could be helpful,” says Hove.
Nonetheless, PSH initiatives are sometimes built-in with hydroelectric turbines, so the identical entity often manages each storage and technology. This implies there isn’t a must switch GECs when the ability is saved, they usually can then be bought with the saved electrical energy.
Not like the extra mature US marketplace for renewable electrical energy certificates, or Europe’s Ensures of Origin scheme (GoOs), China’s GEC system remains to be younger. With buying and selling volumes solely lately taking off, policymakers at the moment are working to handle the challenges of speedy development. The problem for policymakers might be putting the stability between verifying GECs with the required rigour, and incentivising the event of renewable vitality and recent GECs within the first place.
