TL;DR: Australia is undergoing a major energy transition by expanding the Small-scale Renewable Energy Scheme (SRES) to 1 megawatt and investing $100 million in the Distribution Connected Accelerator Program (DCAP). These initiatives target the "missing middle" of energy generation—specifically industrial, agricultural, and mid-scale community solar-battery projects—by slashing upfront costs, speeding up grid approvals, and overcoming traditional financing barriers.
Bridging the "Missing Middle" of Australia's Renewable Transition
For over a decade, Australia's renewable energy landscape has been characterized by two extremes. On one end of the spectrum, residential rooftop solar has experienced massive popularity across the country. Almost 4.5 million Australian households have installed rooftop solar panels, creating a combined residential solar capacity of approximately 22 gigawatts. On the other end, massive utility-scale solar and wind farms have been developed to feed the main transmission lines.
However, this leaves a significant gap in the center of the market—what Climate Change and Energy Minister Chris Bowen terms the "missing middle." While residential solar panels are highly visible from airplanes flying over Australia's capital cities, industrial zones and commercial corridors remain largely bare. Despite having vast, empty rooftop spaces ripe for solar generation, commercial and industrial enterprises have only installed a combined 5.6 gigawatts of capacity. Most of this existing capacity is represented by small-scale systems operating below 100 kilowatts.
According to findings from the Institute for Energy Economics and Financial Analysis, the technical rooftop potential for solar on commercial, industrial, and agricultural buildings exceeds 80 gigawatts. Failing to utilize these large agricultural sheds, factories, logistics warehouses, and supermarket roofs represents a massive missed opportunity for national productivity. Unlocking this capacity not only reduces energy bills but also frees up capital for businesses to reinvest into their daily operations.
To address this gap, the federal government is launching major parallel initiatives. By expanding existing commercial solar schemes and offering dedicated capital financing, the government intends to help businesses, farmers, and local communities deploy mid-scale solar systems and localized battery storage at a much faster rate.
The Expansion of the Small-scale Renewable Energy Scheme (SRES)
To directly address the upfront cost barrier for businesses, the federal government is expanding the Small-scale Renewable Energy Scheme (SRES). Since its inception in 2011, the SRES has driven residential solar adoption by allowing solar installations to generate certificates that are traded on the open market. However, because the scheme was historically capped at 100 kilowatts, most commercial and agricultural properties could not benefit from it. A 100 kW system is sufficient for a household but far too small for a large factory or commercial warehouse.
Under the newly announced expansion, the SRES threshold will be increased from 100 kilowatts to 1 megawatt. This policy change will slash the upfront installation costs of commercial and industrial solar systems by approximately 20 percent. This change represents a major financial shift for businesses:
- Small to Medium Retailers: A retailer installing a 250 kW solar system is estimated to save almost $70,000 in upfront installation costs.
- Large Commercial Complexes: A large retail complex or logistics warehouse installing an 850 kW system can expect to save more than $230,000 on upfront costs.
By lowering the financial entry barrier, the government expects a rapid increase in mid-scale solar installations across the commercial sector. This expansion leverages an established open-market certificate system to provide immediate relief to agricultural and industrial operators.
Accelerating Grid Approvals via Regulatory Reform
Lowering the upfront cost of equipment is only one part of the equation; physical connection to the electricity grid is another hurdle commercial operators face. Historically, businesses and farmers have faced long delays when attempting to get commercial-scale solar installations approved by network providers.
To resolve these bottlenecks, Minister Chris Bowen has announced that he will ask the Australian Energy Market Commission (AEMC)—the nation's energy watchdog—to ensure that network providers approve commercial and industrial solar installations at a much faster pace. These regulatory changes are designed to streamline the grid connection process, ensuring that businesses do not have to wait years to begin generating their own clean energy.
This regulatory push has been welcomed by commercial operators across the country. Maggie Jarrett, the business development manager for See Saw Wine—a winery located on the New South Wales Central Coast—expressed strong support for the changes, noting that faster approval times and reduced upfront costs will make it easier for agricultural businesses to invest in clean energy.
Unlocking Private Capital: The Distribution Connected Accelerator Program (DCAP)
In addition to the SRES expansion, the federal government is addressing financing barriers for mid-scale, community-level energy projects. The government has announced a $100 million investment through the Clean Energy Finance Corporation (CEFC) to establish the Distribution Connected Accelerator Program (DCAP).
Developed in partnership with Infradebt, the DCAP is a specialized financing initiative designed to help small and medium-sized renewable energy projects get built sooner. The program aims to accelerate up to 16 hybrid solar, battery storage, and battery retrofit projects toward construction in 2027.
DCAP will primarily support projects up to 5 megawatts in size. While 5 MW systems are too small to be classed as utility-scale developments, they are large enough to power entire local communities and businesses. Crucially, systems of this size are small enough to connect directly to existing parts of the local distribution network (the "poles and wires" that already exist). This bypasses the need to wait for major, multi-billion-dollar transmission line projects to be completed, allowing clean energy to connect to local grids faster and at a lower cost.
Overcoming Financing Barriers for Mid-Scale Projects
Many technically viable mid-scale projects fail to secure funding because traditional project finance is geared toward much larger developments. Banks and institutional investors often prefer to finance multi-hundred-megawatt utility projects, leaving smaller community-level hybrid projects without access to capital.
DCAP resolves this market failure by providing concessional senior debt. Infradebt, which has financed over 80 infrastructure projects (including more than 40 distribution-connected renewable energy projects) over the past 13 years, will select applicants through a competitive process. This program builds upon a previous $150 million CEFC commitment to Infradebt, bringing a powerful combination of capital and expertise to the mid-scale sector.
By offering concessional senior debt, the program reduces finance barriers, helping technically viable hybrid solar and battery projects access the capital they need. Minister Bowen emphasized that this funding is designed to unlock private investment, get projects built faster, and deliver a more reliable electricity system while putting downward pressure on energy bills.
Integrating Batteries: Lessons from the Residential Sector
The push for commercial battery integration follows a successful trend in the residential market. The introduction of the Cheaper Home Batteries Program in 2025 offered a subsidy covering approximately 30 percent of the upfront cost of home battery systems. This program revitalized residential solar installations, which had begun to slow down, by encouraging households to pair their solar arrays with energy storage.
By applying similar principles to the commercial sector through the DCAP and SRES expansions, the government hopes to duplicate this success. Facilitating the rollout of hybrid solar and battery systems ensures that commercial energy generated during the peak of the day can be stored and used when grid demand is highest, stabilizing the network for all users.
