The transformation of the energy system toward a climate-neutral electricity supply is creating new requirements for market models and contractual structures. In this context, Power Purchase Agreements (PPAs) are emerging as a key instrument for securing renewable energy generation over the long term and meeting the growing demand from industry and commerce for reliable green energy. In the context of a 24/7 energy supply, the focus is on how PPAs can address the volatility of renewable generation, regulatory requirements, and systemic challenges. This session highlights PPAs as a strategic building block for combining security of supply, investment incentives, and climate goals.
