6 FAQs about [Kyrgyzstan inter-seasonal energy storage project]

Does Kyrgyzstan produce electricity in winter?

The volume of water in the winter is typically not enough to generate the winter electricity needed. To meet the energy gap, Kyrgyzstan imports electricity from the neighbouring countries (i.e., Tajikistan and Kazakhstan), especially during winter. During summer, the average flow of a river is higher as compared to winter ( Gassner et al., 2017 ).

Why does Kyrgyzstan need a new focus on hydropower generation?

The Kyrgyz government needs to change the focus from hydropower generation as it suffers from variable hydrology and seasonal demand issues towards more diversified and reliable energy resources to produce power. On the contrary, Kyrgyzstan is blessed with plentiful renewable energy (RE) resources (other than hydro resources) ( IEA, 2020 ).

What is Kyrgyz energy policy?

Outlook to the Kyrgyz energy policy To unleash the RE capacity, the Kyrgyz government introduced the law titled “Renewable energy sources (RES)” in December 2008 ( Ministry of justice of the Kyrgyz Republic, 2008 ). Kyrgyzstan was the first country in Central Asia who implement RE-based law.

How does Kyrgyzstan meet the energy gap?

To meet the energy gap, Kyrgyzstan imports electricity from the neighbouring countries (i.e., Tajikistan and Kazakhstan), especially during winter. During summer, the average flow of a river is higher as compared to winter ( Gassner et al., 2017 ). Fig. 1 gives the comparative impression of residential consumption in winter and summer. Fig. 1.

Does Kyrgyzstan have energy insecurity?

Kyrgyzstan – a Central Asian country – faces a high degree of energy insecurity. Especially the Kyrgyz power sector suffers from outdated infrastructure and is not capable of fulfilling the growing and fluctuating inter-seasonal energy demand.

How has Kyrgyzstan changed its energy policy?

However, the energy policy of Kyrgyzstan was adopted several times since it was implemented. The updated policy draft brought crucial changes to the planning and operation of renewable energy sources. Such changes are imperative to document for the private investors as well as for stakeholders.
