Gas vs Grid: The True Cost Comparison for Industrial Operators in Dubai

For industrial operators in Dubai, the question of whether to stay on the DEWA grid or invest in on-site gas generation is increasingly relevant. With industrial electricity tariffs structured to penalise high consumption and peak demand, the economics of self-generation deserve serious scrutiny. This article breaks down the true cost comparison.

Understanding DEWA's Industrial Tariff Structure

Dubai Electricity and Water Authority (DEWA) applies a tiered tariff structure to industrial consumers. High-consumption users typically pay more per kilowatt-hour than low-consumption users, and peak demand charges can add significantly to monthly bills. For energy-intensive operations running heavy machinery, compressors, or cooling systems around the clock, these tariffs accumulate rapidly.

The Cost of On-Site Gas Generation

On-site gas generation has three cost components: capital expenditure on equipment and installation, ongoing fuel costs, and maintenance. For a well-specified system running on natural gas or LPG in Dubai, the all-in cost of electricity generation is typically lower than DEWA industrial tariffs at high consumption levels. The crossover point — where on-site generation becomes cheaper — depends on your load profile, hours of operation, and gas supply terms.

A Realistic Scenario

Consider a manufacturing facility consuming 2 megawatts continuously. At DEWA industrial rates for high-tier consumption, monthly electricity costs can exceed AED 400,000. A 2.5MW gas generation system, sized with redundancy, can typically produce that same electricity for AED 250,000 to AED 300,000 per month including fuel, maintenance, and amortised capital costs — a saving of AED 100,000 to AED 150,000 every month.

Hybrid Approach: Get the Best of Both

Many Dubai industrial operators are adopting a hybrid approach: maintaining their DEWA grid connection for low-load periods and regulatory compliance while deploying on-site gas generation to cover high-load operations and peak shaving. This hybrid model minimises capital risk while capturing the majority of the savings available from self-generation.
