Grid-scale storage to stabilise Nepal's power system and unlock its hydropower potential.
Typical Outcomes
10 MWh – 100+ MWh · MW-class PCS
System Scale
10–500 MWh
Capital Cost
USD 180–250/kWh (at scale)
Revenue Streams
Ancillary services, arbitrage, capacity
Project Payback
7–12 years (project finance)
Nepal's hydropower-rich grid faces a fundamental paradox: monsoon surplus and dry-season deficit, with limited cross-border export capacity. Utility-scale BESS (10 MWh – 100+ MWh) enables NEA and independent power producers to shift generation, provide frequency regulation, defer transmission upgrades, and export more cleanly. Arsa Energy, as Nepal's official Hithium partner, supplies containerised Hithium ∞Power8 systems — the world's first 8-hour native BESS — from 2 MWh per container to 100+ MWh projects.
Grid frequency regulation (primary & secondary)
Transmission congestion relief & deferral
Monsoon surplus storage & dry-season dispatch
NEA substation-level peak shaving
Renewable energy firming (solar + wind + BESS)
Spinning reserve replacement
Capture Monsoon Surplus
Nepal exports hydropower during monsoon at low prices and imports expensive power in dry season. BESS enables shift-and-dispatch, reducing import bills by USD 20–50M annually at scale.
Frequency Regulation Revenue
A 10 MW / 10 MWh Na-ion BESS providing ancillary services to NEA can generate USD 800,000–1.2M in annual revenue under a proposed ancillary services market.
Defer Transmission Capex
Terai corridor transmission lines running at 85–95% capacity can be relieved by strategically placed BESS — deferring NPR 100–500 crore in upgrades by 5–10 years.
World-First 8-Hour Technology
Hithium ∞Power8 is the world's first native 8-hour BESS — delivering 50%+ lower LCOS vs 2-hour systems for long-duration grid applications.
Every solution is delivered as a complete, commissioned system — not a parts list.
