However, there are quite a number of challenges that hinder the integration and proper implementation of large-scale storage of renewable energy systems. One of the foremost issues is the capital-intensive nature of the rudiments of a storage device such as batteries, pumped hydro storage, and compressed air storage among others.
Renewable energy is derived from clean natural energy sources like sunlight, wind, tidal waves, biomass, and thermal energy stored in the Earth''s crust. Moreover, these energy sources are abundantly available and accessible in some form in many geographies. Furthermore, renewable energy helps reduce energy imports and the usage of fossil fuels.
A community or utility MG is usually fairly similar to an island MG. The key distinction is that there will be no connection to the power grid in most cases. If the distance between the island and the mainland allows it, a cable connection to the utility grid on the mainland may be possible in a few cases. On the other hand, depending on the
However, with the rise of distributed generation and energy self-sufficiency, indeed the notion of ''grid defection'' (coined by the Rocky Mountain Institute), 80 there are new challenges for distributors and these may influence their approach and encourage greater reluctance to connect storage and RES-E quickly and as a priority.
Energy storage systems can store surplus energy and provide power when energy shortages occur since renewable energy sources are unstable and uncertain in production.

Grid-scale storage plays an important role in the Net Zero Emissions by 2050 Scenario, providing important system services that range from short-term balancing and operating reserves, ancillary services for grid stability and deferment of investment in new transmission and distribution lines, to long-term energy storage and restoring grid operations following a blackout.
However, with the rise of distributed generation and energy self-sufficiency, indeed the notion of ''grid defection'' (coined by the Rocky Mountain Institute), 80 there are new challenges for distributors and these may influence
Grid integration of RESs may lead to new challenges related to power quality, reliability, power system stability, harmonics, subsynchronous oscillations (SSOs), power quality, and reactive power compensation.
