How Smarter Energy Storage Is Powering the UK’s Net Zero Future
As the UK pushes towards a net-zero grid, one technology is quickly becoming the backbone of this transition: energy storage. But batteries aren’t working alone. Two powerful shifts — co-location and aggregation — are reshaping how we generate, store, and use renewable energy, making the entire system smarter and more resilient.
AlphaESS UK believes energy should be intelligent, connected, and designed to empower everyone. Here’s how these trends are unlocking a cleaner, more efficient future.
Co-location: Making solar and storage work together
Co-location means placing renewable energy generation, like solar or wind, alongside on-site battery storage so that the power created can be used more effectively. Instead of wasting excess energy when the grid cannot absorb it, batteries capture it and release it later when demand is higher.
Across the country, solar farms and other renewable energy sites are already pairing up with batteries to tackle one of the biggest challenges in clean energy: wasted generation. By storing excess solar energy during the day and releasing it during periods of peak demand, co-located systems ensure that fewer clean electrons go to waste.
The scale of the challenge is huge. In 2024 alone, the UK lost up to £6 billion worth of clean energy simply because there wasn’t enough storage to capture it. In places like Scotland, massive wind farms often generate more power than local grids can handle, forcing operators to curtail — or even switch off — production.
This is where storage steps in. By easing grid congestion, batteries allow more renewable energy to reach homes and businesses across the UK. And with AlphaESS’s scalable battery energy storage systems, developers can future-proof their projects, reduce curtailment losses, and unlock greater returns on investment.
Aggregation: The power of everyday batteries
Aggregation refers to linking together many smaller batteries — often in homes or businesses — so that they can operate as one larger, coordinated system. These “virtual power plants” can supply energy to the grid when it’s needed most, while also helping battery owners earn income.
It’s not just about large-scale projects. Homeowners are becoming a vital part of the energy transition thanks to household batteries. With over 1.3 million UK homes already equipped with solar panels, adding storage unlocks even greater value.
By joining virtual power plants, thousands of small batteries can be aggregated into a powerful network. These systems respond to grid needs in real time, helping to stabilise supply while giving homeowners the opportunity to generate income.
AlphaESS smart inverters and monitoring platforms make this simple, offering users full visibility and control over their energy. And through partnerships across the UK, they’re already delivering meaningful savings for households and businesses alike.
