Does it reasonable to include grid-side energy storage costs in transmission and distribution tariffs? Benefit evaluation based on economic externality
View DetailsGrid companies, which invested in 89% of China's total pumped storage capacity, can now recoup the capex, fixed operating costs, and finance costs with a reasonable rate of return in the form of stable capacity charges.
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power is available, or during a weather event that disrupts electricity generation.
Fitch Ratings-Hong Kong-23 May 2023: China's more granular power transmission and distribution (T&D) tariffs, effective from 1 June, will enhance pricing transparency, support the stable business profile of power grid operators and will encourage power trading and grid-side investment, says Fitch Ratings.
The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
The higher T&D tariffs in certain regions will support the asset-based return model of grid companies, which underpins the companies' credit profiles. The costs carve-outs and elimination of cross-subsidies will also improve the transparency of the asset-based returns.
