    About eXtensa

    eXtensa is the active energy management platform for commercial and strata sites in Western Australia. We operate the batteries, solar, load, and tariff position on sites where energy is a material cost.

    Why We Exist

    The rules under your bill changed. The response didn't.

    The WA electricity market has been quietly restructuring for years. Network tariffs, reserve capacity charges, alternative electricity service regulation, distributed PV controls. The rules underneath every WA commercial energy bill have moved.

    The response on most sites hasn't. Solar systems were installed in 2018 and haven't been re-examined since. Batteries were sized against a business case nobody is operating against. Tariffs were chosen by a person no longer at the company. Load is running on schedules set when the building was commissioned.

    eXtensa exists to close that gap. We operate the assets on commercial sites against the WA market as it is today, not as it was when those assets were installed.

    What We Believe

    Four positions we don't move on.

    Software, Not Hardware

    We don't install. We operate.

    We don't sell batteries, panels, or chargers. We work with whatever's on site and whoever installed it. That boundary keeps us honest about what's worth doing.

    WA-Only

    One market. Run properly.

    We operate in Western Australia. The WEM, Western Power, and the WA regulatory environment. We're not a national platform retrofitted to fit. We're built for one market.

    Aligned Commercial Model

    If it doesn't perform, we don't get paid.

    Our revenue is tied to the value the platform creates on your site. There is no flat subscription that runs whether the platform earns or not.

    Transparent by Default

    Every decision auditable.

    We don't run a black box. The platform's decisions, every interval, are visible and explainable. You see the same view your operator does.

    What We Do

    Six capabilities. One platform.

    Active management of batteries, solar, flexible load, tariff and supply structures, EV charging, and bidirectional vehicles. Six capabilities running on one platform, on commercial and strata sites across Western Australia.

    The Team

    Operators. Not vendors.

    The team behind eXtensa has been operating commercial energy assets, embedded networks, and behind-the-meter sites across Western Australia for years. We've run the bills, signed the supply contracts, dealt with the curtailment events, and seen the difference active management makes on real sites.

    We built eXtensa because operating that way at scale needed a platform. The platform is what we now run for other sites.

    Where We Are

    Perth-based. WA-only.

    We're based in Perth and we operate only in Western Australia. Every site we manage is on the WEM, served by Western Power, and subject to the same regulatory environment we live in.
