Grid-scale battery storage is on a tear. In a single week, utilities and developers on opposite sides of the Pacific announced deals worth billions of dollars and thousands of megawatt-hours, reinforcing the idea that large batteries have moved from experimental curiosity to core infrastructure. Portland General Electric finalized contracts for 650MW of battery storage across Oregon, while Australian developer Edify Energy locked in an EPC partner for 3.6GWh of solar-plus-storage in Queensland. Together, these projects signal that 2026 may become the year grid batteries hit escape velocity. Modern grid management systems coordinate battery dispatch across entire regions. Image: AI-generated Portland General Electric: Oregon's Biggest Clean Energy Deal Oregon-based utility Portland General Electric (PGE) has completed what it calls the largest renewables acquisition in its history. The package spans 1,015MW of combined solar and battery capacity, split between utility-owned assets (42%) and power purchase agreements with third-party developers (58%). Projects are expected to begin serving customers in 2027 and 2028. The contracts emerged from three separate procurement rounds: PGE's 2023 all-source request for proposals, subsequent PPA negotiations, and its 2025 RFP. The Oregon Public Utility Commission oversaw each stage to ensure competitive, transparent bidding. Biglow Optimisation Sherman County, Oregon 125MW solar + 125MW BESS PGE-owned, ~$540M investment. Online late 2027. Wheatridge Expansion Morrow County, Oregon 240MW solar + 125MW BESS Joint ownership, PGE holds 110MW solar + 65MW storage. ~$490M. Meadowlark Battery Washington County, Oregon 200MW BESS Third-party owned, long-term PPA. Online late 2027. Nottingham Battery Washington County, Oregon 200MW BESS Third-party owned, long-term PPA. Online 2028. The four named projects alone account for 650MW of battery storage and 365MW of solar generation. PGE is using existing transmission at the Biglow and Wheatridge sites to reduce interconnection costs, a strategy that more utilities are copying as queue backlogs grow nationwide. PGE is not stopping here. The utility has shortlisted 12 non-emitting projects from its 2025 RFP, targeting roughly 2,500MW of new wind, solar, and storage. It aims to finalize those contracts by the end of Q3 2026, with commercial operation in 2028 and 2029. Australia's Queensland Push: 3.6GWh of Solar-Plus-Storage Large-scale BESS installations are becoming a common sight across Queensland. Image: AI-generated On the other side of the Pacific, Edify Energy has selected DT Infrastructure as the EPC contractor for two massive solar-plus-storage developments in Queensland. The combined capacity is 1,080MWp of solar paired with 900MW/3,600MWh of battery storage. The first cluster, Smoky Creek and Guthrie's Gap in Banana Shire, will feature 720MWp of solar and 600MW/2,400MWh of batteries. The second, Ganymirra and Majors Creek near Townsville, adds 360MWp of solar with 300MW/1,200MWh of storage. Both projects use DC-coupled hybrid configurations, where solar panels feed current directly to batteries through DC/DC converters before a single inversion step for grid connection. DC coupling offers several advantages over AC-coupled systems. It reduces conversion losses by eliminating a second inverter stage, and it allows excess solar generation that would otherwise be clipped to charge batteries directly. Both sites will also use grid-forming inverters, which can synthesize their own voltage and frequency reference rather than relying on synchronous generators. This capability is becoming critical as coal plants retire across eastern Australia. Why It Matters: Queensland's energy roadmap depends on replacing retiring coal capacity with a mix of renewables and storage. At 3.6GWh, these two projects alone could store enough energy to power roughly 300,000 Australian homes for four hours during evening peak demand. Construction is expected to begin in the first and second quarters of 2026, with Edify CEO Ben Warne noting the projects will create hundreds of construction jobs in regional communities. Australia Hits 250,000 Home Batteries Solar-plus-storage installations are scaling rapidly at both utility and residential levels in Australia. Image: AI-generated While utility-scale projects grab headlines, Australia's distributed storage sector is quietly building momentum of its own. Australia's home battery fleet has grown far beyond the early-2026 baseline, with June reporting putting the installed base near 600,000 systems. The federal Cheaper Home Batteries Program is now framed less as a niche household rebate and more as a grid resource that must be coordinated. Those home batteries serve a dual purpose. Homeowners use them to store rooftop solar for evening consumption, cutting their electricity bills. Aggregated into virtual power plants, those same batteries can inject power back into the grid during demand spikes, reducing the need for gas peaker plants. The residential battery boom complements the utility-scale buildout. A grid with both centralized BESS facilities and thousands of distributed home batteries is more resilient than one relying on either alone. Centralized systems handle bulk energy shifting and frequency regulation; home batteries provide local backup and reduce transmission congestion. June 2026 Update: The Boom Is Real, But Coordination Is the Constraint Three months after this article first ran, the storage buildout looks less like a short burst and more like the new operating model for grids with heavy solar penetration. PGE now says 475MW of battery storage procured through its 2021 request for proposals is online and delivering power to the grid. Independent project tracking listed six operating utility-scale battery projects in Oregon in June 2026 with about 523MW of total capacity. That operating base changes the meaning of PGE's newer 650MW battery package. The February deals are not an isolated jump from zero. They are the next tranche on top of a storage fleet that is already dispatching in Oregon, with PGE still targeting roughly 2,500MW of additional clean energy and storage agreements by the end of Q3 2026. Oregon operating storage 523MW Tracked utility-scale battery capacity as of June 2026 Australia connected pipeline 45GW Battery projects counted by AEMO among connected projects Australia home batteries 600K Approximate installed systems cited in June reporting Australia's June 2026 signals are more complicated. AEMO's latest planning work still points to very large storage needs, including tens of gigawatts of battery capacity by 2050, and media summaries of the plan cite 67GW of connected projects with 45GW in batteries. At the same time, AEMO warned that project delays could leave renewables at about 75% of generation in 2030, short of the 82% policy target. The residential battery story is moving even faster than expected. Australia now has roughly 600,000 home batteries, but many are not enrolled in virtual power plants or other orchestration programs. That creates a grid-planning paradox: households are buying the hardware, but system operators cannot count on much of that capacity unless software, tariffs, and customer programs catch up. Updated Read: Battery deployment is no longer the question. Dispatchability is. The next competitive edge belongs to utilities and markets that can turn installed batteries into coordinated capacity during evening peaks, network constraints, and solar oversupply events.
