RenewCo Energy targets $65 million after 36 battery deferrals

By Daniel Okafor

RenewCo Energy reports $39.0 million in revenue and 134% growth, and targets $65 million in installed sales over the next 12 months.

Founded in 2021 by Mark Summerville and Matthew Summerville, RenewCo Energy has its head office in Lane Cove West, NSW. The company lists 60 employees, operates in the Power & Utilities industry and lists renewcosolar.com.au as its website. Its present scale rests on a model built around direct delivery rather than outsourced installation.

RenewCo's business now spans solar, batteries, EV charging and heat pumps. The company says design, installation and support sit within one organization. That structure gives customers one accountable provider from the first consultation onward and gives RenewCo tighter control over its booked work.

The figures capture momentum, but RenewCo's account also shows how sensitive the model can be to policy timing and operating capacity.

Why did the Summervilles reject fragmented solar sales?

RenewCo says Matthew Summerville had spent years working in solar when frustration with the after-sales process took hold. The problem began after many systems were sold.

RenewCo says sales businesses outsourced installation, installers could disappear after a job finished, and homeowners sometimes had to chase different companies when they needed support. That chain of handoffs drove the founders' pitch.

RenewCo says it deliberately chose not to pursue only customers looking for the cheapest solar deal. Continuity after installation mattered as much as securing the sale.

After saving for eight years, Matthew Summerville launched RenewCo with his father, Mark, in 2021. The new company designed, installed and supported home energy systems itself. Customers dealt with one company from the first consultation onward. The founders sought to keep post-sale support under one roof.

What did the May 2024 incentive announcement cost?

RenewCo's operating model faced a serious test in May 2024, when the New South Wales government announced a household battery incentive almost six months before its scheduled start. The announcement changed customer timing while RenewCo held a pipeline of booked work.

RenewCo says 36 of its 40 booked battery installations were deferred. Those deferrals pushed $3.6 million in revenue back and created a $450,000 cash-flow hit in four weeks.

RenewCo kept its team in place while changing how it forecast demand, bought materials and scheduled work during the incentive delay, rather than rushing customers into early installations. The company used the slowdown to improve training, quality control and internal systems.

Those changes gave RenewCo a platform for the next demand shock. The company had preserved its operating capacity and rebuilt the processes supporting that capacity instead of relying on short-term sales tactics.

Did the operating reset handle the rebate surge?

Those changes soon faced another test. RenewCo says a later federal rebate triggered a 400% surge in leads. Demand rose just as the company had revised forecasts, purchasing and scheduling.

RenewCo says the rebound tested the same internal systems rebuilt during the slowdown, and those systems absorbed the extra demand without adding back-office staff. The company did not need to expand its administrative organization to handle the increase.

The first shock tested whether RenewCo could carry capacity through a lull; the second tested whether it could process a surge. RenewCo reports that its team absorbed both changes without adding back-office personnel.

Where does RenewCo expand next?

RenewCo now wants to take the business beyond NSW, with Queensland first on its expansion list. Queensland will be the first test of the direct-service model outside the company's home market.

Over the next 12 months, RenewCo targets $65 million in installed sales while considering acquisitions of other operators across its solar, battery, EV charging and heat-pump business. Acquisitions remain under consideration rather than completed transactions, according to RenewCo.

Expansion gives RenewCo more scale and more product lines, but it also puts direct delivery under greater pressure. RenewCo says the central challenge is growing without recreating the fragmented model the Summervilles set out to avoid.

RenewCo's next proof point is Queensland: whether new categories and possible acquisitions can scale direct design, installation and support without recreating the fragmentation its founders set out to avoid.
