Tasmanian households and businesses could see downward pressure on electricity bills following a significant federal investment of up to AUD$1.5 billion into two major renewable energy projects. The Cellars Hill Wind Farm and Weasel Plains Solar Farm have secured government-backed revenue support through the Australian Government’s Capacity Investment Scheme (CIS), a move announced in late May 2026 that underscores Tasmania’s growing role in the national clean energy transition.
These two projects, with a combined generation capacity of 541 megawatts (MW), are projected to power approximately 160,000 Tasmanian homes, bolstering the state’s energy security and contributing to its ambitious goal of 200% renewable energy by 2040. The announcement, made by Federal Assistant Minister for Climate Change and Energy, Josh Wilson, highlights the strategic importance of Tasmania’s renewable pipeline.
Driving Tasmania’s Renewable Future
The Cellars Hill Wind Farm, with a planned capacity of 341 MW, and the 200 MW Weasel Plains Solar Farm are being developed by Gamuda Renewable Pty Ltd, a subsidiary of Malaysian infrastructure group Gamuda Berhad, in partnership with Alternate Path and local landowners, the Downie family. Both facilities are strategically located near Bothwell in Tasmania’s Central Highlands and will connect to an existing 220-kilovolt transmission line, facilitating efficient grid integration.
Construction of the Weasel Plains Solar Farm is anticipated to commence in early 2027, with the Cellars Hill Wind Farm expected to begin development in 2028. This phased approach to construction will generate an estimated 500 jobs during the build phase, followed by 22 ongoing operational and maintenance roles, providing substantial economic benefits for regional communities.
“This outcome confirms the strength of our renewable energy pipeline and Tasmania’s vital role in powering Australia’s energy future,” stated Tasmanian Minister for Energy and Renewables, Nick Duigan, following the announcement. “These two projects, with a combined value of up to $1.5 billion, have the capacity to generate up to 500 megawatts of clean, reliable energy, enough to power approximately 160,000 homes.”
The Capacity Investment Scheme Explained
The Capacity Investment Scheme (CIS) is a federal initiative designed to accelerate renewable energy deployment across Australia by underwriting investment in new clean energy generation and dispatchable capacity. By providing revenue certainty through long-term contracts, the CIS aims to reduce investment risks for developers and attract private capital into critical energy projects. These Tasmanian projects are part of a broader round of successful bids under the CIS, which is crucial for achieving Australia’s target of 82% renewable electricity by 2030.
The scheme offers a government-backed revenue safety net for up to 15 years, ensuring that projects remain financially viable even during periods of market volatility. This mechanism is vital for de-risking large-scale renewable developments and encouraging the rapid build-out of infrastructure needed to replace retiring coal-fired power stations. The federal government recently opened registrations for CIS Tender 9 on May 25, 2026, targeting an indicative 5 GW of renewable generation capacity across the National Electricity Market (NEM), excluding New South Wales.
Complementing State-Level Investments
This federal funding complements significant state-level commitments in Tasmania’s energy sector. The 2026-27 Tasmanian Budget, announced on May 22, 2026, committed AUD$1.8 billion towards energy generation and network asset upgrades. This includes approximately AUD$880 million for Hydro Tasmania to modernise its hydropower system and AUD$970.5 million for TasNetworks to progress Stage 1 of the North West Transmission Developments project, which is critical for the Marinus Link connection to the mainland.
These combined federal and state investments are designed to future-proof Tasmania’s electricity supply and enhance its export potential as a net energy exporter. The Marinus Link, a proposed undersea interconnector, is expected to unlock additional Hydro Tasmania returns of around AUD$470 million per year once operational, further supporting essential services within the state.
Broader Implications for Australian Energy Consumers
The success of projects like Cellars Hill and Weasel Plains under the CIS demonstrates a concerted effort to expand Australia’s renewable energy capacity, which is expected to translate into more stable and potentially lower electricity prices for consumers over the long term. As more renewable energy comes online, the reliance on volatile fossil fuel markets diminishes, providing greater energy security.
For homeowners considering their energy options, the ongoing shift towards renewables and supportive government policies highlight the increasing viability of clean energy solutions. Understanding how these large-scale projects integrate with the grid and impact wholesale prices can inform decisions around household energy consumption and investments. For those looking to minimise their energy expenditure, strategies such as optimising energy use during off-peak hours can be highly effective.

The federal government’s continued investment through schemes like the CIS, coupled with state-specific initiatives, is accelerating Australia’s transition to a cleaner, more reliable, and ultimately more affordable energy future. These latest Tasmanian projects are a tangible step towards that goal, promising both environmental benefits and economic stability for the state.
