Electricity Units
Average kW × equivalent hours/day × operating days. This gives estimated monthly kilowatt-hours (kWh), not a machine guarantee.

OWC Machine Running Cost & Electricity Calculator
Estimate what an organic waste converter could cost to operate at your site. Calculate electricity units and monthly expense separately from labour, additives and maintenance. All figures are adjustable planning assumptions—not published energy ratings or a quotation.

Estimate Your OWC Operating Cost
Enter measured or supplier-confirmed values wherever possible. Connected load (kW) is not the same as actual average consumption (kW); heating duty-cycle, ambient temperature, waste moisture and processing schedule affect actual kWh.
1. Waste & electricity inputs
2. Other monthly operating costs
Understand the result
How the Calculation Works
Power Cost
Estimated kWh × ₹/unit + optional incremental fixed charges. Local tariff, demand charges and billing rules vary.
Total Cost / Kg
(Electricity + incremental labour + consumables + maintenance + other costs) ÷ monthly kg. Higher utilisation spreads fixed costs over more waste.
An 18–24 hour processing cycle does not mean heaters and motors consume full connected-load power continuously. Use actual interval meter readings for meaningful comparisons.

What Changes Real OWC Running Cost?
Heating duty cycle
Heater on/off time, moisture content and insulation can materially change consumption.
Waste and segregation
Excess water, non-biodegradables, plastics and fibrous contaminants change processing and maintenance needs.
Machine utilisation
Nominal 100 kg/day capacity does not mean a site always processes 100 kg every day.
Operator workflow
Waste collection, sorting, loading, removal and curing are facility activities that may require labour.
Electricity billing
Tariff slabs and fixed/demand charges depend on the customer's connection and utility.
Spare parts and service
Replacement heaters, shredder blades, bearings and scheduled preventive maintenance affect total cost.

Capacity should be selected from measured daily segregated waste, waste characteristics, installed electrical capacity and actual operating schedule—not the lowest calculator result alone.

OWC Electricity & Cost FAQs
How many electricity units does an OWC machine use?
Actual usage depends on the model, heating duty cycle, waste moisture, insulation and operating practice. Multiply measured average kW by equivalent daily hours and operating days for a planning estimate; request model-specific readings from DSC Engineering.
Does 5 kW connected load mean 5 units per hour all day?
Not necessarily. Five kW running continuously for one hour would consume 5 kWh, but connected load is not proof of continuous average consumption. Motors and heaters can cycle on and off.
Does this include machine purchase and installation?
No. This calculator is an operating-cost tool. Purchase price, installation, infrastructure, freight, taxes, depreciation and finance are outside the calculation.
Does higher capacity automatically mean cheaper composting?
No. Total cost per kg depends on utilisation, power, labour, maintenance and waste characteristics. Oversized equipment can increase underutilised fixed costs.
Can I use this estimate in a tender or quotation?
Use it for early feasibility only. Tender and contractual estimates need verified model-specific electrical measurements, duty cycle, site utility tariff and commercial terms.
Is wet waste converted directly into ready-to-use compost?
Not necessarily. Depending on the technology and feedstock, processed material may require additional curing and quality checks before use as mature compost.
