What TagEnergy does
TagEnergy, S.A. is a Lisbon-headquartered Independent Power Producer founded in 2019 by Impala SAS Group and now controlled by TagHolding SAS, a joint venture between Impala and Exor N.V., with Mirova and Omnes as additional institutional shareholders. The company develops, finances, constructs, owns, and operates utility-scale wind farms, solar farms, and battery energy storage systems (BESS), with an aggregated portfolio exceeding 12GW across the UK, Australia, Spain, Portugal, France, Germany, and Japan. Its flagship asset, the 1,333MW Golden Plains Wind Farm in Victoria, is the Southern Hemisphere's largest onshore wind farm; the company also operates the 240MW/480MWh Cernay-lès-Reims BESS (France's largest operational battery) and a six-site 320MW UK BESS portfolio.
TagEnergy commercializes electricity through long-term Power Purchase Agreements (PPAs) with utilities and hyperscalers, virtual tolling agreements for storage capacity, and merchant sales into wholesale markets such as Australia's National Electricity Market. Named offtake counterparties include Snowy Hydro, EnergyAustralia, Amazon Australia, and Ingka Investments (IKEA), while the in-house TagX platform supports trading and dispatch optimization. Revenue is recognized through contracted subscription-style offtake and usage-based merchant and grid-services streams; pricing is bilaterally negotiated and not publicly disclosed. The business model is asset-heavy and capital-intensive, funded to date by a €450 million equity raise (2022), a €570 million green bond (2023), and partnerships with development banks and institutional co-investors such as Banque des Territoires.
The company pursues a merchant-first development model — exemplified by Golden Plains being advanced without pre-secured PPAs — and has built an in-house execution stack combining project development, procurement (Tesla Megapack, Vestas turbines), construction oversight, and asset management across five-plus geographies. Headcount is concentrated in Lisbon, London, Paris, Sydney, Melbourne, and Madrid, with senior leadership drawn heavily from ex-Neoen executives.

Revenue model
- Power Purchase Agreements (PPAs): Long-term contracts with corporate and utility customers to offtake renewable energy generation. Examples include agreements with EnergyAustralia (40% of Stage 2 capacity), Snowy Hydro, and Amazon Australia.
- Virtual Tolling Agreements: Long-term storage capacity contracts where partners like Snowy Hydro pay for access to battery storage capacity without building, owning, or operating their own facilities. The 15-year, 105MW agreement with Snowy Hydro provides predictable revenue streams.
- Merchant Electricity Sales: Direct sale of electricity generated from wind farms into wholesale energy markets. The Golden Plains Wind Farm operates on merchant basis with some capacity traded in the National Electricity Market (NEM).
- Grid Services and Energy Arbitrage: Revenue from providing grid stability services, capacity during peak demand periods, and energy arbitrage through charging during low-price periods and discharging during high-price periods.
- Carbon Credits and Renewable Energy Attributes: Sale of Renewable Energy Certificates and attributes to corporate buyers seeking to offset their carbon footprint, including partners like Ingka Investments claiming electricity output and renewable energy attributes.
