stations for load management in the electricity grid. PSS would be in high demand for meeting peak load demand and storing the surplus electricity as India graduates from an electricity deficit to an electricity surplus. They also produce secondary /seasonal power at no additional cost when rivers are flooding with excess water. Storing electricity by other alternative systems such as batteries, compressed air storage systems, etc is costlier than electricity production by standby generator. India has already established nearly 4785 MW pumped storage capacity which is part of its installed hydro power plants. Wind power India has the fourth largest installed wind power capacity in the world. As of 31 December 2017, the installed capacity of wind power was 32,848 MW an increase of 4148 MW over the previous year Wind power accounts for nearly 10% of India's total installed power generation capacity and generated 52.666 billion kWh in the fiscal year 2017-18 which is nearly 3% of total electricity generation. The capacity utilisation factor is nearly 16% in the fiscal year 2017-18. The Ministry of New and Renewable Energy (MNRE) of India has announced a revised estimation of the potential wind power resource (excluding offshore wind power potential) from 49,130 MW assessed at 50m Hub heights to 102,788 MW assessed at 80m Hub height at 15% capacity factor. Solar energy India's solar energy insolation is about 5,000 T kWh per year (i.e. ~ 600 TW), far more than its current total primary energy consumption. India's long-term solar potential could be unparalleled in the world because it has the ideal combination of both high solar insolation and a big potential consumer base density. Also a major factor influencing a region's energy intensity is the cost of energy consumed for temperature control. Since cooling load requirements are roughly in phase with the sun's intensity, cooling from intense solar radiation could make perfect energy-economic sense in the subcontinent located mostly in the tropics. Installation of solar power PV plants requires nearly 2.0 hectares (5 acres) of land per MW capacity which is similar to coal-fired power plants when life cycle coal mining, consumptive water storage & ash disposal areas are also accounted for, and hydropower plants when submergence area of the water reservoir is also accounted. 1.6 million MW capacity solar plants can be installed in India on its 1% land (32,000 square km). There are vast tracts of land suitable for
