Current Status of Domestic Shared Energy Storage: A Deep Dive into China’s Energy Revolution

Shared Energy Storage: The New “Airbnb” of China’s Power Grid

Imagine a giant, grid-connected “charging” (power bank) that multiple energy providers can rent on demand. That’s the essence of China’s booming domestic shared energy storage sector. As of 2025, shared (chǔ néng, energy storage) projects are reshaping how renewable energy is stored and distributed nationwide. For instance, the 355MW/920MWh shared station in Chengde, the largest of its kind, now acts like a community battery for wind and solar farms. But why is this model gaining traction? Let’s unpack the trends, challenges, and real-world examples driving this energy revolution.

From Pilot Projects to Powerhouse: The Rise of Shared Storage

China’s shared market is exploding faster than a lithium battery in a heatwave (don’t worry, safety protocols are in place!). Consider these stats:

• 54.91% of new energy storage projects in 2023 were shared systems
• 60.64GW of new shared capacity expected from 2024–2028
• Over 15 provinces have rolled out supportive policies, including Shandong’s groundbreaking 2023 model converting dedicated storage to shared systems

Take the Datang Minning 100MW/200MWh project in Ningxia. This “” (grid-forming storage) pioneer uses cutting-edge tech to stabilize local power supply while earning revenue through multiple channels. It’s like a Swiss Army knife for the grid – multifunctional and always handy!

Four Money-Making Moves for Shared Storage Systems

How do these giant batteries turn a profit? Let’s break down their revenue playbook:

1. Capacity leasing: Renting out storage space to renewable plants (like office subletting for electrons!)
2. Ancillary services: Getting paid for grid stabilization – the “yoga instructors” of the power system
3. Spot market trading: Buying low (when wind blows at night) and selling high (during daytime peaks)
4. Capacity compensation: Earning subsidies for being on standby – the energy equivalent of a retainer fee

The Huadian Haixi 270MW project in Qinghai, currently China’s largest (single-unit) shared station, leverages all four strategies while surviving -30°C winters. Talk about cold hard cash!

Challenges: Not All Sunshine and Lithium Rays

Despite the hype, shared faces hurdles thicker than a battery’s casing:

• Economic viability: Some projects still rely on policy crutches. As expert Wu Junhong notes, “Shared’s necessity ties directly to mandatory renewable storage policies”
• Market mechanisms: Only 20+ provinces have clear rules for as independent grid participants
• Tech diversity: While lithium dominates, innovators like the 100MW (vanadium flow battery) project in Jilin prove alternatives work even in extreme cold

Remember the (shared bike) bubble? Industry leaders are determined not to repeat that “bike graveyard” scenario. The key lies in smarter policies – like Fujian’s station that doubles as a (offshore wind) stabilizer while trading on energy markets.

The Future: Where Policy Meets Power Electronics

Three trends are electrifying the sector’s roadmap:

• Mega projects: National initiatives like the 2027 are pushing GW-scale deployments
• Tech hybridization: Projects like Minning’s 20% + 80% hybrid showcase adaptive solutions
• Provincial competition: From Shandong’s market reforms to Yunnan’s pilots, regions are racing to innovate

As Chen Haoyong from South China University of Technology quips: “Shared is like co-raising a child – everyone chips in, everyone benefits”. With projects now storing enough juice to power 1.5 million homes daily (look up’s 240MWh beast), this “energy babysitting” model might just save our green power future.
