State Grid Corporation of China (SGCC), which operates roughly 80 percent of the nation's electricity grids spanning across 26 provinces, has unveiled plans to massively expand its battery storage fleet and pumped hydro storage capacity and thus help the nation move towards its decarbonization goals.
SGCC Chairman Xin Baoan said Wednesday in a commentary published in the state-owned People's Daily that SGCC aims to have 100GW of battery storage by 2030, up from 3GW today. This is a very ambitious goal, given that BloombergNEF forecasts that all of China will have about 96GW of battery storage by 2030.
De acordo com um plano de cinco-anos divulgado esta semana, a China pretende reduzir os custos de armazenamento de bateria em cerca de 30% até 2025, abrindo caminho para que as indústrias locais dominem o mercado global até 2030. Além disso, o décimo quinto quinto{ {4}}plano anual elaborado pela Comissão Nacional de Desenvolvimento e Reforma (NDRC) e pela Administração Nacional de Energia (NEA) dá atenção especial ao armazenamento de ar comprimido e prevê que essa tecnologia realizará aplicações de engenharia em unidades de 100 MW de capacidade.
But SGCC's plans don't end only with battery storage, the grid operator is also planning to increase its pumped storage capacity from the current 26.3GW to 100GW by 2030. This builds on its announcement in January when it said it had commissioned the world's largest pumped-hydro facility. Located in Hebei province, the 3.6GW Fengning Pumped Storage Power Station consists of 12 reversible pump generating sets with a capacity of 300MW each and has a power generation capacity from storage of 6.612 billion kWh. To put SGCC's plans into perspective, China is targeting 120GW of operational pumped-hydro facilities by 2030, according to the NEA.
Além disso, Xin disse que o SGCC também está planejando aumentar sua capacidade de transmissão de energia entre-províncias e apoiar o desenvolvimento de energia solar e eólica nas áreas desérticas do oeste. Por fim, ele disse que a operadora de rede também buscará implementar transmissão CC flexível, usinas de energia virtuais, segurança e estabilidade de grandes redes elétricas e comutadores de derivação de ultra-alta tensão-, entre outras tecnologias.
According to Xin, SPCC made these plans to align with the Chinese government's dual carbon goal to reach peak carbon emissions by 2030 and achieve carbon neutrality by 2060. China's decarbonization policy has already created pressure on state-owned enterprises mandating energy storage with the order to build renewables-plus-storage projects introduced for the very first time by the NEA last April.
In terms of supporting policies, NEA, the country's major energy policymaking authority, has already launched a series of incentives and advisory documents with an eye on the interim goal to deploy 30GW of energy storage capacity by 2025. In addition, several provinces have also released policies supporting storage for renewable energy installations.
Mas, apesar de seus planos de descarbonização, a China continua respondendo por uma grande parte das adições globais de carvão. Um relatório recente publicado por três think tanks e lobistas ambientais descobriu que a China abriga 55% do gasoduto mundial para novas instalações de carvão e, juntamente com Índia, Vietnã, Indonésia, Turquia e Bangladesh, respondem conjuntamente por 82% dos planos para novas usinas de carvão.
