Potential developers will soon be invited to submit proposals for energy storage demonstration projects in India, with the Power Grid Corporation of India (PGCIL) and the country’s Ministry of New and Renewable Energy (MNRE) actively seeking demonstration projects.
Last week, MNRE issued a request for comments, observations and feedback on a draft ‘Expression of Interest for Energy Storage Demonstration Projects for Supporting Renewable Energy Generation’. The ministry referred to the important role energy storage could provide in assisting the integration of renewable energy sources. It will consider both small and grid-scale projects.
The invitation from MNRE to stakeholders will look at installing four demonstration projects. These will examine key types and uses of energy storage, beginning with the integration of large-scale wind and solar resources into India’s transmission grids. MNRE will also look at proposals for demonstration projects working with rural micro-grids, micro-grids for commercial, industrial, residential, defense and other applications and also at large-scale standalone storage systems.
PGCIL on the other hand, is inviting tenders for three categories of 500kW/250kWh energy storage demonstration projects. It will examine lithium-ion, advanced lead acid, with the third category of projects to include large-scale sodium nickel chloride (molten salt), alkaline, and flow batteries. Citing a predicted 33GW of renewable energy to be added to the grid by the end of 2017, PGCIL says batteries could “ensure stability of the grid balancing mechanisms”.
The news follows last week’s publication by MNRE of guidelines for the next round of its national solar programme, expected to begin later this year.
