Lessons from the history of independent system operators in the energy
Independent system operator. Electricity transmission. Gas transmission. 1. Energy market liberalisation and system operation. The electricity sector in many countries was, until the early 1990s, dominated by relatively large integrated utilities that operated along the different stages of the value chain.
To adapt to the physical characteristics of energy storage, some foreign independent system operators have explored the market participation mechanisms for new energy storage. In China, a series of domestic power system reform documents have emphasized the importance of capacity remuneration mechanisms to encourage new
