As Australia races to decarbonise its grid, a quiet revolution is unfolding – powered not by mega-projects, but by small and mid-scale energy systems delivering big local impact.
Moving with Australia’s power shift is Specialised Energy Solutions (SES), a seasoned full-service energy partner now driving the national rollout of battery and hybrid solar-battery installations for councils, communities and businesses.
With large-scale renewables gaining maturity, SES sees opportunity in the growing demand for energy resilience at the local level – particularly in regional and peri-urban areas where grid capacity is strained and the benefits of distributed energy are immediate.
Smarter, smaller, sooner
“Smaller installations deliver tangible benefits faster,” says Aaron Mulhall, SES General Manager.
“They often come with lower cost barriers and can be deployed where they’re needed most.”
From rural towns managing peak demand to urban councils looking to cut energy bills and emissions, battery energy storage systems (BESS) and hybrid solar + BESS setups are enabling more Australians to store clean energy and use it when it matters.
For SES, the focus on small to medium-scale BESS projects is an expansion of the company’s deep engineering roots. Long known for its work in utility-scale renewables, SES now applies that same rigour to more modest-sized systems, treating every installation as critical infrastructure.
Utility discipline
Smaller projects don’t mean simpler execution. In fact, SES says they often come with their own set of challenges – tight budgets, constrained sites, legacy infrastructure and unique community needs.
“Whether a project is 500 kilowatt-hours [kWh] or five megawatt-hours [MWh], we bring the same engineering, procurement and construction [EPC] discipline,” says Mulhall.
That includes detailed engineering, modular technologies, grid compliance, and hands-on commissioning support.
The aim is to deliver systems that are not only technically sound but also resilient, scalable, and easy to maintain.
Regional sites come with particular complexities, such as limited logistics, resources, and fragile grids. SES tackles these with robust design, flexible delivery models and localised operations. Urban installations, by contrast, demand close coordination with existing infrastructure and careful mitigation of construction disruption.
Where integration matters
For many clients, battery projects still carry an assumption that storage is simply bolted on to solar. SES warns that this mindset can be costly.
“Battery integration is more than adding storage,” says Alba Ruiz Leon, SES Non-Executive Director.
“It requires precise coordination between photovoltaic (PV) inverters, control systems and the grid.”

SES’s end-to-end delivery approach ensures all components work together from day one. That includes navigating regulatory frameworks, commissioning with full visibility, and avoiding compatibility pitfalls that too often surface post-installation.
“We’re often brought in to fix projects that were rushed or underspecified. Even seemingly minor oversights – like installing terminations in wet weather – can lead to catastrophic failures months later,” says Ruiz Leon.
Balancing speed with precision
SES acknowledges that clients want systems delivered quickly, but cautions against cutting corners.
“We explain upfront that speed can’t come at the expense of quality,” says Mulhall.
“Rushing key electrical work, especially under poor site conditions, creates latent defects that surface just after warranty periods. That’s when repair costs skyrocket.”
Instead, SES uses modular designs and proven frameworks to enable fast, clean execution – without compromising on durability or safety.
Every project is backed by rigorous quality assurance and clear client communication about long-term performance and risk.
Maximising uptime
An energy system is only as good as its ongoing performance. This is why SES offers comprehensive Operations & Maintenance (O&M) services, with a focus on reliability, cost-efficiency, and asset longevity.
Its O&M suite includes preventive maintenance, real-time diagnostics, fault response, and lifecycle optimisation. Importantly, SES helps clients pinpoint recurring issues – such as mismatched components or underperforming inverters – and resolves them through technical support and root-cause analysis.
“We treat every project like a long-term partnership,” says Ruiz Leon.
“Our job doesn’t end at commissioning – it truly begins there – we remain committed throughout the asset’s entire lifecycle.”
“We guide clients to make the best long-term decisions. A slightly higher spend today can mean far lower O&M and better energy returns over the system’s life.”
Living values
SES’s approach to project delivery is grounded in three core principles: integrity, innovation and sustainability.
In practice, this means providing clear communication, realistic timelines and transparent pricing to support long-term client relationships. It also means designing site-specific solutions that draw on current technologies in hybrid PV and battery storage, rather than defaulting to off-the-shelf systems.
Sustainability informs both strategic choices and day-to-day decisions, with a focus on building energy systems that offer lasting value to clients while supporting broader decarbonisation goals.
With battery prices falling, market demand rising, and community-led projects gaining momentum, SES believes the next wave of energy transformation will be hyper-local.
“Big or small, every project matters,” says Mulhall.
“This is how we power the future – one installation at a time.”
