Enosi's solar matching surges in Italy with Plenitude

Australian clean energy technology company Enosi says demand for its solar energy-matching technology has surged in Italy through Plenitude's Adopt a Panel programme, which signed up more than 82,000 customers within 10 months.

The programme is aimed at renters and apartment dwellers, who often cannot install rooftop solar but still face high electricity costs. It uses Enosi's Powertracer platform to match a customer's electricity use with an allocated share of output from a large solar farm, then applies bill credits based on the production of those panels.

Customers pay a monthly fee to rent access to a panel allocation. When they use electricity tied to their panel's generation, that energy is free, creating an incentive to shift consumption into daytime periods when solar output is available.

Adopt a Panel has expanded quickly in Italy. The 31 MW Porto Torres solar farm in Sardinia has already been fully allocated, subscriptions are filling for a second solar farm, and a third project is in planning.

The pace of take-up points to demand beyond the usual base of environmentally minded early adopters. Enosi says the product has found a market among consumers excluded from direct participation in the energy transition because they do not own suitable property or cannot make upfront investments.

Access gap

The Italian rollout also highlights a broader issue in Australia and other markets where rooftop solar has spread unevenly. Renters and people living in multi-unit buildings often have limited access to the lower electricity costs available to households that own homes with solar panels and battery storage.

In Australia, about 30% of households rent, and only a small share of apartment buildings have rooftop solar, according to Enosi. That leaves a large section of consumers more exposed to volatile energy prices, while households with their own generation gain more control over bills.

Policy efforts are starting to address that imbalance. Australia's emerging Solar Sharer model is due to begin on July 1, but Enosi drew a contrast between its time-matched approach and measures that require retailers to price electricity at zero during specific hours regardless of whether solar generation is actually available.

It argues that the Italian model shows retailers can offer a mainstream product linked to actual renewable generation without taking on that risk. The system matches energy by time of production and consumption rather than relying on broad monthly averaging.

Changing demand

The argument comes as energy markets are increasingly shaped by supply security, affordability and grid resilience. Higher power prices and concerns about exposure to global fuel markets have pushed more consumers to look for ways to tie their energy use to domestic renewable supply.

That has made the timing of energy use more important. Instead of treating clean electricity as interchangeable across long periods, retailers and technology providers are starting to build products around when generation occurs and whether consumers can respond to those signals.

Enosi Chief Executive Officer Steve Hoy said: "Plenitude's success reflects a deeper shift in how electricity is generated, valued and consumed, and the ability of energy matching to unlock value for the consumer, the energy supplier and the renewable energy generator.

"Energy is no longer something that can be averaged out over a year and assumed to be equivalent.

"The grid is dynamic, increasingly decentralised, and shaped by what happens at specific times of the day. Now that consumers can see and benefit from when clean energy is actually produced, it changes behaviour and it changes demand."

Supporters of this approach say it can lower costs for consumers by moving demand into periods of strong solar output. They also argue that shifting usage away from evening peaks can ease pressure on the grid and reduce the system costs associated with high-demand periods.

For retailers, the appeal lies in linking customer offers to traceable generation rather than offering blanket discounts that may not align with supply. For generators, it creates a direct retail route to consumers who want a defined relationship with a renewable asset but cannot host one themselves.

Australian relevance

The Italian experience is likely to be watched closely in Australia as governments, retailers and technology companies search for ways to broaden the benefits of renewable energy. If access remains concentrated among property owners, the risk is a two-tier market in which one group can generate, store and manage electricity costs while another faces rising bills without equivalent options.

Plenitude's rollout suggests there is strong consumer demand for products that close that gap. With one solar farm fully subscribed and further projects being lined up, the model offers evidence that matched solar access can attract large numbers of mainstream households rather than a narrow niche of specialist customers.
