Origin Energy: An Australian Powerhouse in Electricity, Gas, and Solar

By Brendan Bostock | 27 May 2026

TL;DR: Origin Energy is one of Australia's largest integrated energy companies, providing electricity and gas to millions of customers across the eastern states. They also offer solar panel and battery installations directly, alongside various solar-friendly electricity plans and feed-in tariffs. They hold a significant position in both traditional energy supply and the growing renewable energy sector.

What Is Origin Energy's Core Business in Australia?

Origin Energy operates as a major integrated energy company across Australia, involved in energy generation, wholesale, and retail. The company supplies electricity and natural gas to approximately 4.5 million customer accounts, primarily in Queensland, New South Wales, Victoria, South Australia, and the Australian Capital Territory. This broad reach makes them a household name for many Australians seeking essential energy services for their homes and businesses. Origin also manages one of Australia's largest energy generation portfolios, including gas-fired power stations and an increasing number of renewable assets.

How Big is Origin's Customer Base?

Origin Energy serves a substantial portion of the Australian energy market. With over 4.5 million electricity and gas customer accounts, they are a dominant force, particularly in the competitive eastern states. This large customer base allows them to offer diverse product lines and invest in infrastructure and new technologies, including solar and battery solutions. Their scale means they interact with a significant number of Australian households daily, making their policies and offerings impactful across the energy sector.

What Types of Energy Services Do They Offer?

Beyond standard electricity and gas supply, Origin offers a variety of energy services. They provide installation and financing options for solar panels and home battery storage systems, helping customers generate their own power. Origin also sells LPG cylinders for homes and businesses, demonstrating their wide scope in energy provision. Additionally, they operate broadband internet services, often bundled with energy plans, to provide a more comprehensive utility offering for their customers.

How Does Origin Support Solar Customers?

Origin provides several services specifically tailored for homeowners adopting solar power. They directly facilitate the installation of solar panel systems and battery storage, helping customers generate and store their own renewable electricity. Once solar is installed, Origin offers a range of electricity plans designed to maximise savings for solar households, including competitive feed-in tariffs (FiTs) for surplus energy exported back to the grid. They aim to make the transition to solar straightforward, from initial consultation to ongoing energy management.

Origin's Solar Installation Services

Origin Energy acts as an authorised installer for solar panel systems and home batteries. They offer a selection of solar panel brands and battery solutions, including models from reputable manufacturers. Customers can receive a comprehensive quote for a new system, often including installation, system design, and assistance with government rebates such as the Small-scale Technology Certificates (STCs). This "one-stop shop" approach simplifies the process for many homeowners looking to install solar.

Solar-Specific Electricity Plans and Feed-in Tariffs (FiTs)

For solar owners, Origin offers various electricity plans with different feed-in tariff structures. These FiTs represent the credit received for each kilowatt-hour (kWh) of excess solar energy exported to the grid. While specific rates vary by state and plan, Origin's FiTs typically range from around 4 cents to 8 cents per kWh. Some plans also feature higher peak usage rates balanced by more attractive off-peak or solar export rates, allowing solar customers to choose a plan that aligns with their usage patterns. It is always wise to compare their current offers against those from other retailers.

What Role Does Origin Play in Australia's Renewable Transition?

Origin Energy is actively involved in Australia's shift towards renewable energy, both through direct generation and enabling customer-side renewables. They operate several renewable energy assets, including the Stockyard Hill Wind Farm in Victoria, one of Australia’s largest, and the Mortlake Power Station, which can run on gas and supports grid stability as more intermittent renewables come online. Origin aims to progressively retire its coal-fired power station, Eraring, by 2025, which represents a significant step in decarbonising its generation portfolio. They also invest in virtual power plants (VPPs) and grid-scale batteries to integrate more renewable energy efficiently.

Origin's Renewable Energy Generation Assets

Origin owns and operates a diverse portfolio of generation assets that contribute to the National Electricity Market (NEM). This includes substantial investments in wind and solar farms. The Stockyard Hill Wind Farm provides 530 MW of clean energy to the grid, complementing other renewable projects and long-term power purchase agreements (PPAs) with third-party renewable generators. Origin also explores pumped hydro energy storage solutions, such as the Shoalhaven Hydro Scheme, which plays a crucial role in grid stability and energy storage.

Future Directions and Green Initiatives

Origin has outlined clear plans to accelerate its renewable transition. The planned closure of Eraring Power Station by 2025 highlights a commitment to moving away from coal. In its place, Origin looks to develop large-scale battery storage solutions, like the 700 MW battery proposed at the Eraring site, to support the grid during peak demand and integrate more renewable power. They also pursue green hydrogen projects and carbon reduction initiatives to meet their stated climate targets and support Australia's broader energy transformation.

How Does Origin Compare to Other Australian Energy Retailers for Solar?

Origin stands out due to its comprehensive, integrated service model, from generation to retail and direct solar installation. While many retailers offer electricity plans, fewer provide in-house solar panel and battery installation services across multiple states. Origin's size means they often have a wider array of plans and competitive bundling options, but smaller, often state-specific, retailers sometimes offer niche plans or higher feed-in tariffs tailored to specific regions. Customers often weigh Origin's broad service offering against potentially higher FiTs or specialised customer service from smaller providers.

Feed-in Tariffs and Plan Options

When comparing Origin's solar offerings, their feed-in tariffs typically fall within the middle range of the market. While some smaller retailers might offer promotional FiTs above 10 cents per kWh in certain areas, Origin's standard rates often sit between 4 and 8 cents per kWh, depending on the plan and location. However, Origin’s plans often include other benefits, such as bill credits, discounts on supply charges, or competitive usage rates, which can balance out a lower FiT for some households. It is important to consider the total value of the plan, not just the FiT.

Customer Service and Support

Origin provides customer support through various channels, including phone, online chat, and a dedicated mobile app. Their size means they process a large volume of customer inquiries daily. Many solar customers find the Origin app useful for tracking their energy usage and solar generation. Like any large company, customer service experiences can vary, but Origin invests in digital tools to enhance the customer experience, particularly for those managing solar assets. Regular online reviews and independent energy ombudsman reports offer insights into customer satisfaction levels across the industry.
