Transmission Rates Keep Climbing

Have you noticed the transmission rate on your energy bill increasing recently? You are not imagining things. In some areas, rates have increased over 75%! Regardless of whether transmission costs are billed by the utility or passed through to you on your retail energy supplier bill, this costly line-item is undoubtedly putting pressure on your energy budget. Understanding and being attentive to transmission rates is the first step in managing and controlling your transmission costs.

How Transmission Costs Are Calculated

Transmission is the part of electric service that deals with transporting electricity from the place of generation to the place on the grid where the power is being consumed. This occurs at high voltages and across long stretches of geography. It is up to the system operator (such as PJM or MISO) to ensure that the amount of MW supplied to the grid at any given moment matches the amount of MW consumed. Given that the transmission grid must be built to deliver power during all conditions, including times of peak usage, transmission costs are assessed based upon peak demand.

Each transmission line has a maximum “carrying capacity” of how much current can be passed through before its thermal limit is reached. When a transmission line is being pushed against its limits, this creates a reliability concern for the system operator, as well as a state of congestion. These conditions can cause local energy price spikes as expressed in the Locational Marginal Price of energy (LMP). Conditions of high congestion imply an inefficient energy market and potentially unreliable status of power supply. In an effort to avoid these conditions, transmission owners invest in system upgrades and improvements. The cost of these upgrades is then incorporated into the transmission rates charged to customers.

So, to maintain the utility’s capacity, reliability, maintenance, and operation of the transmission infrastructure, a rate is determined by a utility-specific formula that is updated and approved on an annual basis. This rate, approved by the Federal Energy Regulatory Commission (FERC), is referred to as Network Integrated Transmission Service or NITS.
