The rapid growth of renewable energy is transforming grid operations globally. Services like inertia and reactive power, once inherent to traditional thermal generation, are now procured through ancillary service markets to maintain system stability. Power-electronics-based assets, such as battery storage and inverter-based resources, are well-suited to provide these services, unlocking new revenue opportunities in emerging markets. Siemens Energy collaborates with investors, developers, and operators to capture this value, optimize project economics, and improve long-term investment outcomes.
