Solar & Storage Live 2026: From “What is flexibility?” to “How do we make it work?”

Last week, the Joulen team attended Solar & Storage Live UK 2026 in Birmingham, and one thing was immediately apparent: the industry is moving faster than ever.

The event felt noticeably busier than previous years, with packed exhibition halls, crowded conference sessions, and a constant flow of conversations across the solar, battery storage, EV, and energy management sectors. While the technologies on display continue to evolve, the biggest change was the nature of the conversations being held.

A few years ago, much of the discussion centred around explaining flexibility and educating the market on the potential value of flexible assets. Today, that conversation has shifted dramatically.

The question is no longer "What is flexibility?"

The question is now "How do we actually make it work for our sites and customers?"

The market has moved beyond theory

One of the strongest themes from this year's event was the growing maturity of the flexibility market.

Asset owners, installers, developers, energy management providers, landlords and facility managers increasingly understand that flexibility can create significant additional value from energy assets. The challenge is no longer awareness; it is implementation.

Organisations are actively looking for practical routes to market, proven operational models, and trusted partners that can help them access flexibility and trading revenues without creating additional complexity for their customers.

This represents an important shift for the industry. Flexibility is moving from an emerging concept into a commercial reality.

Commercial & industrial opportunities are expanding rapidly

Another key takeaway was the significant growth in interest across the commercial and industrial (C&I) sector.

Businesses are investing heavily in on-site solar generation, battery energy storage systems (BESS), EV charging infrastructure, and energy management systems. As these assets become more widespread, attention is naturally turning towards maximising their value.

Many organisations are beginning to recognise that these assets can do far more than simply reduce energy bills. When intelligently managed, they can participate in flexibility and trading opportunities that generate additional revenue streams while supporting grid stability.

The scale of opportunity across the C&I market is substantial, and it was encouraging to see so many organisations exploring how they can monetise flexibility alongside their traditional energy savings objectives.

Residential battery flexibility continues to grow

While commercial and industrial applications attracted significant attention, the residential market remains incredibly strong.

The appetite for residential battery optimisation and flexibility services continues to increase, driven by growing battery adoption, dynamic tariffs, and greater consumer awareness of energy costs.

Homeowners are increasingly looking beyond simple self-consumption models and are seeking ways to unlock further value from their battery systems. This trend is creating significant opportunities for installers, manufacturers, aggregators and energy management providers that can offer compelling flexibility propositions.

Residential flexibility is no longer a niche concept. It is rapidly becoming a fundamental component of the modern smart home energy ecosystem.

Flexibility is expanding beyond batteries

Perhaps one of the most interesting developments from this year's event was the growing focus on flexibility from technologies beyond battery storage.

Heat pumps, HVAC systems, hot water systems and other controllable electrical loads are increasingly being recognised as valuable flexible assets in their own right.

As the market matures, there is a growing understanding that the future energy system will require orchestration across multiple technologies rather than relying on batteries alone. The ability to intelligently coordinate generation, storage, heating, cooling and electric vehicle charging will be critical to maximising both customer value and grid benefits.

This broader view of flexibility creates exciting new opportunities for technology providers and asset owners alike.

How Joulen Can Help

The conversations we had throughout the week reinforced a simple message: organisations want practical ways to unlock value from their assets.

Whether you are:

• An installer looking to enhance your customer offering
• A solar or battery developer seeking additional revenue streams
• An EMS or HEMS provider wanting to integrate flexibility and trading services
• A landlord looking to maximise returns from building infrastructure
• A facility management company managing large and complex energy estates

There is an opportunity to generate additional value through flexibility and energy trading.

At Joulen, we help organisations access these opportunities by connecting, optimising and trading flexible energy assets across residential, commercial and industrial portfolios. Our platform enables asset owners and technology providers to participate in flexibility and energy markets while maintaining a simple and seamless customer experience.

Looking ahead

Solar & Storage Live 2026 demonstrated that the energy transition continues to accelerate. The technologies are maturing, asset adoption is increasing, and market participants are becoming more sophisticated in how they think about value creation.

The industry's focus is no longer on whether flexibility works.

It is on how quickly organisations can implement it and start benefiting from it.

For businesses investing in solar, battery storage, EV charging, heat pumps, HVAC systems and other flexible technologies, the opportunity has never been greater.

The future of energy is flexible, and it is already here.
