Agricultural Energy Consumption

Summary

Agricultural energy use in Nepal — small in total volume, but strategically central to food security, diesel displacement, and rural electrification outcomes. Agriculture employs ~60% of the workforce but accounts for only 0.95% of final energy — because most farm work is manual and most farm energy is human and animal labour, not fuel.

Coverage / Method

• Data sources: WECS Energy Sector Synopsis FY 2079/80 (agricultural energy balance by fuel); NEA Annual Report FY 2024/25 ("Others" category sales, agricultural feeder references); World Bank Water Sector Diagnostic (irrigation coverage, water demand projections).
• Method: Agricultural energy from WECS sectoral energy balance (on-farm only, excluding agro-processing classified under industrial). Diesel displacement calculation assumes 3× electric motor efficiency advantage over diesel engines. Tubewell counts are estimated from WB Water Sector Diagnostic and NEA rural electrification references.
• Known gaps: NEA does not report agricultural electricity separately (falls under "Others"). Tubewell count (~100,000+) is an estimate, not a registry. Agro-processing energy is classified under industrial, so agricultural energy balance understates total farm-sector energy use.

Caveats

• Agro-processing excluded: WECS classifies sugar mills, tea dryers, and food processing under "Industrial," not "Agriculture." Including agro-processing would roughly double the agricultural energy figure.
• Tubewell count is estimated: ~100,000+ shallow tubewells is an order-of-magnitude estimate, not a verified census.
• Diesel displacement calculation is stylized: Assumes full electrification of all diesel pumps; actual electrification is constrained by grid extension, capital cost, and reliability.
• Single-year snapshot: FY 2079/80 data; agricultural energy mix may shift as electrification and mechanization advance.

Agricultural Energy Mix

The Diesel Dependence Problem

Agriculture is the sector where diesel displacement from electricity would have the clearest and most immediate payoff:

Geographic Concentration

Agricultural energy use follows the farming geography:

1. Terai belt (Madhesh, Lumbini, Koshi, Sudurpaschim southern districts): 80% of tubewell irrigation. Shallow and deep tubewells concentrated in the eastern and central Terai where groundwater is accessible. Diesel pumps dominate (70%+ of tubewells), electric pumps are growing as grid extends.

2. Mid-hills (Gandaki, Bagmati outside valley): Surface lift irrigation from rivers and streams. Smaller schemes, many diesel-powered. Micro-hydro serves some milling and pumping.

3. Mountain region (Karnali, northern districts): Minimal commercial energy use in agriculture — largely rain-fed, manual, and animal-traction.

The Tubewell Electrification Opportunity

Nepal has an estimated ~100,000+ shallow tubewells (STWs) and several thousand deep tubewells (DTWs) in the Terai, predominantly diesel-powered. The government's policy direction — mentioned in NEA's FY 2024/25 report — is to encourage electricity use for irrigation alongside cooking and transportation.

Key enablers for electrification:

• Grid extension into agricultural feeders — NEA is actively extending 33/11 kV lines into rural Terai
• Dedicated agricultural tariff — Nepal has historically had separate irrigation tariffs, though their adequacy is debated
• Solar irrigation pumps — AEPC has deployed thousands of solar irrigation pumps under alternative energy programs (see Rooftop and Solar Home System Deployment for the off-grid solar context)

Key barriers:

• Capital cost of electric pumps — upfront cost is higher than diesel pump sets
• Connection charges — NEA requires transformer and feeder costs for high-load connections
• Reliability in remote areas — power quality and outage frequency in rural feeders remain worse than urban
• Diesel subsidy legacy — diesel has been subsidized or price-controlled, undermining the economic case for switching

Agricultural Electricity in NEA Sales

NEA does not report agricultural electricity separately — it falls within the "Others" category (10.48% of FY 2024/25 sales, 1,183 GWh) which also includes street lighting, temporary connections, and water supply pumping. The actual agriculture-only slice within "Others" is estimated at **200–350 GWh** based on:

• WECS cross-tab showing 315 GWh-equivalent (1,134 TJ) agricultural electricity consumption in FY 2079/80
• Some of that 315 GWh includes water supply pumping for municipal use (classified differently in NEA categories)

The Water-Energy-Food Nexus

Agriculture in Nepal is where the water-energy-food nexus is most visible:

• 75% of Nepal's water withdrawals go to agriculture (irrigation), nearly all from surface sources
• Only ~38% of irrigable land is currently irrigated year-round (WB Water Sector Diagnostic)
• Groundwater irrigation is concentrated in the Terai, where 1.9 BCM is consumed vs 8.8 BCM total recharge — significant untapped potential
• Storage hydropower could enable seasonal irrigation releases that currently can't be scheduled without reservoirs — linking Storage Deficit to food security

The Budhigandaki Hydroelectric Project, West Seti Hydroelectric Project, and Pancheshwar Multipurpose Project projects all have irrigation components in their design mandates, but none are currently under construction. The gap between potential multipurpose storage and actual irrigation delivery is one of Nepal's largest infrastructure underproviders.

Growth Outlook

Agricultural energy demand is likely to grow from a very low base for several reasons:

1. Irrigation expansion — government targets to increase year-round irrigated area from ~38% to >60% by 2035
2. Pump electrification — tubewell diesel-to-electric switching driven by both reliability and cost
3. Climate adaptation — more frequent dry spells require more pumped irrigation to stabilize crop yields
4. Mechanization — tractors, threshers, and powered equipment replacing animal and manual labour as farm labour migrates to cities and abroad

The counter-force is agricultural employment decline — as people leave farming, the energy-per-worker may rise but total agricultural energy could plateau if cultivated area contracts.
