The state government on Tuesday took a decision to encourage large-scale private investment in the hydropower sector by introducing a separate policy for Pumped Hydropower Storage(PHS) Projects through Public Private Partnership (PPP). The decision was taken in a cabinet meeting chaired by Chief Minister Eknath Shinde.
Under this technology, two reservoirs are connected through a tunnel or underground pipe at different heights. If there is more electricity production and less demand, these projects pump water from the downward reservoir to the upward reservoir. In case higher energy is required, water is released from the higher reservoir to the lower one via a turbine to produce the required power instantly. The system works well for grid stability and maintaining peak power.
According to an official, currently 10,757 MW of non-conventional energy is produced in the state.
By 2025, this energy capacity is targeted to reach 25,000 MW. But the energy generated by solar as well as wind is not sufficient.
As a result, gaps in renewable energy capacity may pose challenges to the grid as a whole. As such, the energy storage system has huge significance since It can balance the grid by providing energy from energy storage systems to other conventional power plants.
“In case of interruption in power generation or breakdown, energy can be available from this system. The Union Ministry of Energy has also decided to encourage PHS projects in the country,” the official said, adding that the policy will encourage development of megawatt level energy storage capacity from the PHS system, encourage existing pumped hydro solar hybrid power projects, inter-basin transfers and attract private sector investment.
“The developer in this context will be selected through direct allotment or competitive tender process through mutual agreement. Capacity can be increased through the energy storage system through the Udchan project. Moreover, it is eco-friendly and cheap,” the official added.
