It is reported that India and the United States have agreed to establish a 5-year research program valued at 30 million U.S. dollars for the purpose of developing smart grid and energy storage technologies. "Smart grids and energy storage technologies will transform our power generation and consumption patterns and reduce carbon emissions by expanding the use of renewable energy sources." US Energy Secretary Moniz said that "cooperation with India will accelerate the introduction of technologies that help reduce technology Cost and solution to improve grid reliability. " The United States-India Partnership for Clean Energy (PACE), the United States Department of Energy (DOE) and the Indian Ministry of Science and Technology (MST) have pledged to invest 1.5 million U.S. dollars each year to extend their research efforts in five years. It is worth mentioning that the United States and India's private sector will help the government to complete the plan, the total investment over the next five years will reach 30 million U.S. dollars. In 2009, the two countries set up PACE to support the research and deployment of clean energy technologies. PACE is the core mechanism of bilateral energy R & D cooperation between the United States and India and mainly covers three areas: research (PACE-R), deployment (PACE-D) and acquisition (PEACE). Subsequently, the leaders of the two countries established a new energy smart city partnership through a series of initiatives to promote India's efforts to build an efficient urban energy infrastructure; launched a new project to expand grid-connected renewable energy in India; stepped up " Energy-for-energy access "project; release more private sector investment; establish a new clean energy financing forum to promote investments and trade in clean energy projects. In 2012, India and the United States launched three studies focusing on solar energy, building energy efficiency and a new generation of biofuels. Today, the fourth study will focus on smart grids and energy storage technologies. The Indian government had previously introduced the National Solar Initiative (NSM), which aims to achieve 20 GW of solar energy by 2022. However, with the recent trade disputes over the import of solar panels and components used in the project, the already growing bilateral cooperation between the two countries has encountered obstacles. In February this year, the WTO made a ruling favorable to the United States in the case of the United States v. India's solar panels and battery components. In April, India decided to appeal the ruling. As countries successively ratify and implement the "Paris Agreement" adopted at the Paris Climate Conference, the two governments led by Modi and Obama also started to discuss the issue of jointly coping with global warming. Despite trade disputes between the two sides, the United States is likely to still support India in reaching the development goal of renewable energy. India had promised at the Paris conference that by 2030 its domestic share of non-fossil-fuel power generation will rise to 40%. In March of this year, India first time put energy storage projects as a necessary condition for solar bidding. This is good news for battery makers, suggesting that the new market, with its huge potential, is open. India's state-owned solar company's general manager said the company will do its job in implementing the government's green goal, with a bidding of 100 megawatts of energy storage for a tender of 750 MW for Andhra Pradesh in southern India. The purpose of the pilot program is to ensure a stable supply of clean energy electricity.
