The Republic of is a in the region of . During the colonial period most large companies were owned and run by Europeans, and operated under concessions from the colonial government. After independence in 1962, the state took over operations of several of the companies. Subsequently the state founded a number of state-owned companies to handle specific sectors of the economy, such as sugar, cotton, textile. [pdf]

Under the direction of the national “Guiding Opinions on Promoting Energy Storage Technology and Industry Development” policy, the development of energy storage in China over the past five years has entered the fast track.
Among them, Pumped Hydro Energy Storage (PHES) accounted for the largest proportion of the total installed capacity of energy storage in China, close to 99%, followed by electrochemical energy storage that is being rapidly developed in recent years.
Even though several reviews of energy storage technologies have been published, there are still some gaps that need to be filled, including: a) the development of energy storage in China; b) role of energy storage in different application scenarios of the power system; c) analysis and discussion on the business model of energy storage in China.
It also introduces the application scenarios of energy storage on the power generation side, transmission and distribution side, user side and microgrid of the power system in detail. Section 3 introduces six business models of energy storage in China and analyzes their practical applications.
Second, there is still a lack of effective market mechanisms in energy storage industry. At present, the application of energy storage in China is mainly distributed power generation and grid connection of micro-grid and renewable energy. There were few applications of power transmission and distribution and auxiliary services.
While it is true that the development of China's energy storage industry has moved from a technical verification stage to a new stage of early commercialization, the industry still faces many challenges which hinder development, and true "industrialization" has not yet materialized.

Solar energy is widely available in Armenia due to its geographical position and is considered a developing industry. In 2022 less than 2% of Armenia’s electricity was generated by solar power. The use of solar energy in Armenia is gradually increasing. In 2019, the European Union announced plans to assist Armenia towards developing its solar power capacity. The initiat. . According to the , Armenia has an average of about 1720 (kWh) solar energy flow per square meter of horizontal surface annually and ha. . As of April 2019 ten 1 MW strong solar stations are installed. Solar and wind stations account for less than 1% of total installed electricity generation capacities. In April 2019 it was announced that German company Das En. In this article, we address the current state of solar energy in Armenia, potential investments and industrial developments in the solar energy sector. [pdf]
