Spinning reserves refer to an ancillary service with the purpose of providing online reserve capacity synchronized to the grid and ready to meet electric demand within 10 minutes of a dispatch instruction by a grid operator. In more general terms, spinning reserves are reserves that are quick to come online and are typically used as bridge power to supply the grid with energy until longer-duration assets can come online. In the absence of spinning reserves, a system operator would typically shed load until the system is back in balance, or slower ramping assets can come online. Systems especially constrained, such as power grids in Hawaii and India, operate this way.
The spinning reserves market is specific to a grid system and depends on generation or load events. Grid systems are facing more instability as energy mixes change rapidly – particularly as intermittent renewable energy systems come online – and load profiles also become more unpredictable, especially in markets experiencing volatility in domestic or industrial load, such as China and Germany, respectively. Opportunities in the spinning reserves market will hinge on key-market structures which are also expected to change over time.
