Solar The highest solar potential is estimated for Kazakhstan with 3,760,000 MW of solar PV (UNIDO and ICSHP, 2016). An estimate by the Central Asia Data Gathering and Analysis Team (CADGAT) is 6684 TWh/year (Eshchanov et al., 2019).
In Tajikistan, the solar PV potential is estimated at 195,000 MW (UNIDO and ICSHP, 2016).
The Central Asian region is endowed with a sizeable potential for small-scale hydropower (Table 1). In Kazakhstan, the estimated potential is 4800 MW for plant capacity of up to 35 MW, and 2707 MW for less than 10 MW (UNIDO and ICSHP, 2016).
Addressing these barriers will help Central Asian countries reach a higher level of energy security, through diversification of sources, provision of access to a greater number of people, and greening of the energy supply.

Meanwhile, electricity produced at solar power plants amounted to 563.14 million kWh in 2019 (QazaqSolar, 2020a), and in the first quarter of 2020, production was at 196.17 million (QazaqSolar, 2020b), which increased to 603.41 million kWh in the first half of 2020 (Ministry of Energy of Kazakhstan, 2020).
In Kyrgyzstan, the solar PV potential is 267,000 MW (UNIDO and ICSHP, 2016). With solar insolation of 1000–1700 kW/m 2 (or 1500–1900 kW/m 2 (ESMAP, 1997)), the potential for solar energy is estimated at 490 GWh/year for thermal and 22.5 GWh/year for electric energy (Asian Development Bank, 2014, Stamaliev, 2010, Umbriel Temiraliev, 2015).
