Grid-forming BESS not yet confirmed for minimum system strength in Australia as AEMO launches fault current trial

Curated by · TechCapsules ·

AI-summarised brief · reviewed before publication

The Australian Energy Market Operator (AEMO) has launched a trial to determine if grid-forming battery energy storage systems (BESS) can provide protection-quality fault current, a critical requirement for minimum system strength in the National Electricity Market. While grid-forming inverters have demonstrated voltage waveform stability, they have not yet been confirmed to meet the higher fault current standards historically supplied by synchronous machines. This technical uncertainty persists as coal-fired generation retires, increasing reliance on alternative solutions. AEMO’s 2026 General Power System Risk Review identifies grid-forming BESS as a potential supplement to synchronous condensers. The trial aims to verify if inverter-based technologies can deliver fault current with sufficient magnitude and duration for reliable protection systems. This assessment carries significant commercial weight, particularly after Transgrid reported a 38% cost increase for synchronous condensers, with Phase 1 costs reaching AU$1.13 billion. Consequently, Transgrid has proposed substituting 900MW of grid-forming BESS for two planned synchronous condensers, pending confirmation that the technology can credibly contribute to system strength levels under National Electricity Rules.

💡 Why It Matters

  • · With synchronous condenser costs surging to AU$1.13 billion, validating grid-forming BESS as a viable alternative is essential to prevent further budget overruns in Australia’s grid modernization.
  • · Success in this trial could redefine infrastructure procurement strategies, allowing operators to bypass expensive mechanical solutions in favor of scalable, inverter-based technologies.

Blocking New Imported Inverters Will Cost America

The FCC on August 2 added foreign‑produced solar inverters to its “Covered List,” barring import of any new models regardless of the manufacturer’s country, including allies such as Germany’s SMA. The rule cites “unacceptable risks” to U.S. national security and personal safety, but exempts previously approved units and those already in service. Critics argue the ban blocks advanced, grid‑interactive inverters that use solid‑state silicon‑carbide technology, improve efficiency, reduce copper use, and enable functions such as battery integration, vehicle‑to‑grid and real‑time load management. Without these capabilities, utilities may rely more on fossil‑fuel peaker plants and curtail excess rooftop solar, raising overall electricity costs and slowing the transition to distributed renewable energy. Domestic manufacturers lack R&D pipelines, forcing prices for U.S. installers.

💡 By shutting out the most efficient, smart inverters, the ban forces utilities to keep fossil‑fuel generators online, directly inflating electricity rates for American consumers.

Concerns over lack of clarity, transparency as US bans foreign power inverters

Concerns over lack of clarity, transparency as US bans foreign power inverters

The Federal Communications Commission’s Public Safety and Homeland Security Bureau announced on July 28 that all newly manufactured “connected power inverters” produced outside the United States are barred from import. The rule targets inverters with Wi‑Fi, cellular, Bluetooth or similar radio‑frequency components that enable remote monitoring or control, labeling them national‑security risks. While the FCC says previously sold or installed units are exempt, it offered no clear guidance on enforcement dates, the definition of “previously authorised” or how the Buy‑America Act’s 65 % domestic‑content threshold applies. Industry experts warn the ambiguity could force a de‑facto ban on most foreign‑made inverters, threatening supply chains for battery‑energy‑storage and solar projects that already rely on imports for up to 60 % of demand in the United States.

💡 The opaque rule could create an immediate inverter shortage, forcing developers to redesign projects or adopt costly work‑arounds and slowing renewable‑energy storage deployment.

‘You cannot build a whole electricity system purely on solar hybrids’: Squadron…

Australia’s National Electricity Market has surpassed 50% renewable energy penetration, driven primarily by solar and battery storage. At the Australian Clean Energy Summit 2026, industry leaders acknowledged this milestone but warned that current investment signals are insufficient for the next phase of grid transition. Squadron Energy CEO Rob Wheals stated that relying solely on solar hybrids would require five times more infrastructure, emphasizing the need for a diversified technology mix. Nevenka Codevelle of AusEnergy Services highlighted Australia’s status as the world’s third-largest market for utility-scale battery storage. However, executives noted that capital is flowing disproportionately to solar and storage due to favorable economics, leaving other essential grid technologies underfunded. James Katsikas of EDF Power Solutions argued that Australia must improve its investment framework to compete globally for foreign capital, citing India’s streamlined development processes as a benchmark. The panel concluded that maintaining the ambition and courage of the first half of the transition is critical to overcoming the tougher challenges ahead in securing a reliable, diversified energy system.

💡 Australia’s heavy reliance on solar and storage creates a structural vulnerability that threatens grid stability as coal exits. Without policy reforms to attract capital for diverse technologies, the country risks inefficient infrastructure expansion and increased costs for consumers.

Samsung SDI is on track to commence lithium iron phosphate (LFP) battery cell production in the United States during the third quarter of 2026. The South Korean manufacturer reported a return to operating profit for the second quarter, marking its first profitability in seven quarters. Revenue reached KRW3.77 trillion, an 18.5% year-over-year increase, driven by strong demand for energy storage systems and high-power batteries for AI data centers. The company attributed this turnaround to a better product mix, favorable US advanced manufacturing production credits, and robust sales in Europe. Samsung SDI aims to secure additional capacity for US battery energy storage system cell manufacturing to meet surging demand. The firm previously debuted its Samsung Battery Box solutions, which utilize domestic production to qualify for tax incentives. With Chinese imports facing restrictions under the One Big Beautiful Bill Act, Samsung SDI is capitalizing on repurposed production lines to serve the growing utility-scale storage market.

💡 The shift to domestic LFP production allows Samsung SDI to bypass new trade barriers that exclude Chinese cells from US tax credits. This strategic pivot secures a competitive advantage in the rapidly expanding American energy storage sector.
