WHES partnered with Tesseract Energy to deliver a 200kW\u002F466kWh PC-G1 energy storage system, giving the site a flexible, AC-coupled platform to turn solar generation into a controllable, revenue-generating asset rather than a fixed-output resource.\n\nThe result is a system built around four coordinated applications — PPA support, solar storage, self-consumption optimisation, and demand control — running from a single all-in-one enclosure.\n\n**Engineered for Flexibility**\n\nThe PC-G1's AC-coupled configuration was central to the design. Rather than tying storage directly to the solar array, AC coupling let the system integrate cleanly with the site's existing PV and switchboard infrastructure, reducing installation complexity while giving the site independent control over charge and discharge behaviour.\n\nThat flexibility is what makes the four applications possible from one system:\n\n- PPA support — the battery helps the site meet the performance and delivery terms of its power purchase agreement\n- Solar storage — excess on-site generation is captured rather than exported at low value\n- Self-consumption — stored energy is prioritised for on-site use, reducing reliance on grid import\n- Demand control — the system discharges during peak demand periods to manage the site's capacity charges\n\nBecause the PC-G1 ships with an integrated EMS, the site avoids the cost and complexity of a separate third-party controls layer — a meaningful simplification for C&I operators who don't want another system to manage.\n\n**A Partnership Built for Delivery**\n\nTesseract Energy managed delivery for this installation, working alongside WHES to get the system commissioned and operating outdoors on-site in NSW. The project reflects the kind of collaboration WHES is building across the Australia C&I channel — pairing WHES's Bloomberg NEF Tier 1-rated hardware with experienced local delivery partners who understand the site-specific realities of commercial energy projects.\n\n**Built for the BESS5 Opportunity**\n\nThis system also lands squarely in the sweet spot of NSW's new BESS5 incentive, commencing 1 September 2026. BESS5 covers C&I batteries from 200kWh up to 30MWh — exactly the bracket this 466kWh system sits in — and it carries one hard requirement most competitors haven’t met: UL9540A certification. WHES's C&I range already holds it.\n\nFor sites like this one, that means access to a rebate that the government's own figures show cutting payback periods roughly in half — from 7–10 years down to as little as 3.8–6.5 years. It's a strong reason for installers and EPCs to bring WHES into future C&I projects ahead of the September launch.\n\nThere's a second tailwind arriving right after: from 1 October 2026, businesses installing eligible systems up to 1MW can access upfront STC incentives, cutting upfront costs by an estimated 20–30%. Stacked with BESS5, it makes projects like this one — and the wider PC-G1 range — an even easier case for C&I customers to act on now rather than wait.\n\n**The Outcome**\nNow live and operating, the system gives the site a genuinely flexible energy asset — one that can flex between self-consumption, demand management, and PPA-linked operation depending on what delivers the most value at any given time. It's a practical demonstration of what a 200kW-class C&I system can do for a business's energy costs and reliability, and a template WHES is looking to replicate across the NSW market as the BESS4\u002FBESS5 rebate scheme comes online.\n\n**Product Featured**\n\n![Description](https:\u002F\u002Fwww.whes.com\u002Fstatic\u002Fpic\u002F8af5849c9fcd465fb4eb4d9f9b4d0c17.png)\n",true,"C&I,energy storage,PC-G1","2","200kW\u002F466kWh","New South Wales, Australia",1,1787903817,{"caseStudyInfo":24,"relatedList":25},["Reactive",7],[],1787903827431]
