How does ICPT ensure fair electricity prices?

Question

Accepted Answer

The Imbalance Cost Pass-Through (ICPT) Mechanism Ensures Fair Electricity Prices Through Transparency and Periodic Adjustments

The Imbalance Cost Pass-Through (ICPT) mechanism is designed to ensure that consumers benefit from transparent and fair electricity prices by reflecting fluctuations in fuel and generation costs. Tenaga Nasional Bhd (TNB) supports this government-mandated mechanism, which has been in place since 2014 and remains relevant in the context of volatile global fuel prices. As a regulated utility, TNB operates under the purview of the Energy Commission (EC), which determines the calculation and methodology for ICPT, subject to government approval every six months.
ICPT Reflects Actual Fuel Cost Fluctuations

The core principle of ICPT is to pass through changes in fuel and other generation-related costs to consumers. For the period of January to June 2020, for instance, global fuel prices saw a significant decline. The average Applicable Coal Price (ACP) was recorded at US$69.5 per metric tonne, which was below the benchmark of US$75 per metric tonne set in the base tariff. Similarly, the gas price for the same period averaged RM26.6 per million British thermal units (mmBTU), lower than the benchmark of RM27.20 per mmBTU. These actual cost reductions were reflected in the ICPT adjustment for July 1 to December 31, 2020, where the surcharge was reduced from 2.00 sen/kWh to 0.00 sen/kWh, directly benefiting consumers.
A Time Lag Allows for System Adjustment

A crucial aspect of the ICPT mechanism is the inherent time lag between fuel price movements and their reflection in consumer tariffs. This lag, typically between six to nine months, is necessary to allow the power sector and the system to adjust. When fuel prices decrease, consumers may only experience a lower tariff approximately 12 months after the initial drop. Conversely, an increase in fuel prices will also be reflected at the consumer level much later. This buffering period ensures that tariff adjustments are not overly reactive to short-term market volatility and provides a more stable environment for both the utility provider and consumers.
Government Approval Ensures Oversight and Fairness

The Energy Commission (EC) is responsible for determining the calculation and methodology of the ICPT. However, these determinations are subject to government approval on a six-monthly basis. This governmental oversight ensures that the mechanism operates within the broader public interest and that any adjustments made are aligned with national energy policies and economic considerations. TNB, as the primary utility company, operates within this regulated framework, committed to providing uninterrupted power supply and maintaining world-class customer service.
Historical Context and Consumer Impact

The ICPT mechanism was introduced in 2014 precisely to address the need for a transparent and fair system in managing the pass-through of fuel cost variations. Prior to its implementation, significant fluctuations in global fuel prices could lead to substantial and sometimes abrupt changes in electricity tariffs, creating uncertainty for consumers. By institutionalising a six-monthly review and adjustment process, coupled with the built-in time lag, ICPT aims to smooth out these variations. This means that while immediate price drops might not be instantly apparent on a bill, the system is designed to pass on these savings over time, ensuring that consumers ultimately benefit from lower input costs when they occur.
