Renewables Boss Shocked by Plunging Battery Prices and Soaring Concrete Costs

Anthony Fowler, CEO of Tilt Renewables, has expressed surprise at the sharp drop in battery storage prices – a win for the clean energy transition. However, this progress is being offset by an unexpected challenge: rising civil construction costs, especially something as basic yet essential as laying concrete slabs for large-scale projects.

Tilt is constructing its first major battery in Victoria’s Latrobe Valley. The cost of battery cells and modules has dropped so dramatically that the company is even considering extending storage duration. Fowler says this trend opens up possibilities for more flexible and efficient energy storage solutions in Australia.

While battery prices improve, balance-of-plant costs, including civil works and labour, are spiking. Fowler points out that building infrastructure in Australia is becoming prohibitively expensive, especially when compared globally. These increasing costs could threaten the financial viability and public support of renewable projects.

Despite cost pressures, Tilt Renewables is moving forward with projects like the 100 MW/200 MWh battery in Morwell, adjacent to Victoria’s brown coal heartland. They're also eyeing new battery projects in South Australia and considering storage additions to their solar farms in Nyngan and Broken Hill.

While solar is no longer a primary focus, Tilt has a growing wind portfolio, including the 1.33 GW Liverpool Plains wind project in NSW, the 288 MW Palmer wind project in South Australia, and plans for projects in Western Australia and South Australia. However, the company notes capital costs are still hovering around $3 million per megawatt, with no sign of decline.

Fowler highlights a major obstacle: delays in planning and environmental approvals. He warns that if timelines don’t improve, Australia may struggle to reach its 82% renewable energy target. Accelerating grid connections and regulatory approvals is now a top priority.
