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.
En virtut d'un pla de cinc-anys publicat aquesta setmana, la Xina té com a objectiu reduir els costos d'emmagatzematge de la bateria al voltant d'un 30 per cent l'any 2025, obrint el camí perquè les indústries locals dominïn el mercat mundial l'any 2030. A més, el quinzè cinc{0} {4}}el pla anual elaborat per la Comissió Nacional de Desenvolupament i Reforma (NDRC) i l'Administració Nacional d'Energia (NEA) presta especial atenció a l'emmagatzematge d'aire comprimit i preveu que aquesta tecnologia realitzi aplicacions d'enginyeria en unitats de 100 MW de capacitat.
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.
A més, Xin va dir que SGCC també té previst augmentar la seva capacitat de transmissió d'energia entre-provincials i donar suport a l'augment de l'energia solar i eòlica a les zones del desert occidental. Finalment, va dir que l'operador de la xarxa també buscarà implementar una transmissió de corrent continu flexible, centrals elèctriques virtuals, seguretat i estabilitat de grans xarxes elèctriques i canviadors de voltatge d'ultra-alta tensió-, entre altres tecnologies.
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.
Però malgrat els seus plans de descarbonització, la Xina continua comptant amb una gran part de les addicions mundials de carbó. Un informe recent publicat per tres grups de reflexió i grups de pressió ambientals descobreix que la Xina acull el 55% del gasoducte mundial per a noves instal·lacions de carbó i, juntament amb l'Índia, Vietnam, Indonèsia, Turquia i Bangla Desh, representa conjuntament el 82% dels plans de noves centrals de carbó.
