Billion Watts has signed a joint development agreement with Australian developer Enervest to accelerate the development of a 50-megawatt (MW) portfolio of distributed solar and battery storage projects across New South Wales and Victoria.
The partnership will focus on a 50MW/200MWh portfolio comprising 10 sub-five MW sites across the two states.
By connecting directly to local distribution networks rather than high-voltage transmission lines, the small-scale assets will enhance local grid stability, system strength, and power resilience.
Under the agreement, Billion Watts, a subsidiary of the Taiwan-based integrated energy platform, Billion Electric Co., will deploy development capital and oversee system integration and asset strategy.
Enervest, meanwhile, will lead project origination and local development. The partners expect all 10 sites to secure development approvals and formal Offers to Connect by June 2027.
Operating within Australia’s National Electricity Market (NEM), the batteries will capitalise on highly diversified revenue models.
The assets will drive commercial value through energy arbitrage, charging when solar power is cheap and discharging during peak demand, as well as participating in Frequency Control Ancillary Services (FCAS) markets to keep the grid stable.
Billion Watts Director Elaine Chen said distributed storage was rapidly emerging as a vital asset class for modern power systems, offering unique deployment flexibility and risk diversification.
“Australia is a highly attractive market with its mature regulatory framework and stable demand,” Chen said.
“By collaborating with local partners, we are accelerating our asset deployment to ultimately build a robust, cross-regional energy portfolio platform.”
Looking ahead, Billion Watts will continue to deepen its presence in Australia, scaling distributed energy projects to build a portfolio of energy assets with stable, long-term returns.
Enervest CEO Ross Warby said the partnership enabled a structured expansion of the developer’s sub-five MW platform.
“Distribution-connected assets are becoming increasingly important in maintaining local reliability,” Warby said.
“By developing projects across multiple regions, we are building a repeatable model that supports more efficient portfolio delivery at scale, while delivering certainty and long-term resilience for communities and network operators.”
