Understanding Your BGE Bill: What You'll Learn in This Guide

Baltimore Gas and Electric (BGE) serves over 1.3 million customers across central Maryland and Washington, D.C., providing natural gas and electric services to homes and businesses. Your BGE bill can seem complicated with multiple charges, rates, and line items that vary month to month. This free informational guide walks through the different parts of your bill so you can understand what you're paying for and why costs might change from one month to another.

The guide explains how BGE calculates your charges based on usage measured in kilowatt-hours (kWh) for electricity and therms for natural gas. It covers the difference between supply charges, delivery charges, and various fees that appear on your statement. By learning what each section means, you can track your own consumption patterns and understand how seasonal changes affect your costs.

BGE customers pay an average of about $110-$140 per month for combined gas and electric service, though this fluctuates based on usage, time of year, and your service plan. Winter months typically show higher bills due to heating needs, while summer months may increase if you use air conditioning heavily. The guide provides information about these seasonal variations so you know what to expect throughout the year.

Understanding your bill structure helps you identify billing errors, spot unusual charges, and make informed decisions about your energy use. The guide includes real examples of typical bills from different seasons, showing how the same household's charges might look in January versus July. This educational resource does not provide billing services but rather helps you interpret the information already on your statements.

Practical Takeaway: Keep several months of your BGE bills together as you read through this guide. Comparing your actual bills to the examples in the guide makes the information more meaningful and helps you spot patterns in your own usage.

Breaking Down Your Bill: Understanding Each Charge

Your BGE bill contains several distinct sections, each representing a different type of charge for the services you receive. The first major component is the supply charge, which represents the cost of the actual gas or electricity you consume. This charge is calculated by multiplying your usage (measured in kWh or therms) by the rate per unit. BGE's rates vary based on your service classification—residential customers pay different rates than commercial customers—and may also differ based on the time of use or your specific rate plan.

The delivery charge is separate from the supply charge and covers the cost of maintaining the infrastructure that brings gas or electricity to your home. This includes the poles, wires, pipes, maintenance crews, and technology systems that ensure reliable service 24 hours a day. The delivery charge is typically higher in winter for gas service because BGE must maintain system capacity to meet peak demand when heating needs are greatest. For electricity, the delivery charge is more consistent year-round.

Beyond supply and delivery, your bill may include several other charges and fees:

• Regulatory assessment fees that fund oversight of utility services
• Municipal tax, which varies by your location within BGE's service territory
• Miscellaneous surcharges related to environmental programs or system improvements
• Late payment fees if your previous bill was not paid by the due date
• Reconnection fees if service was disconnected and then restored

Some customers may also see credits or adjustments on their bills. These might reflect seasonal rate adjustments, billing errors from previous months, or credits from energy conservation programs. The guide provides examples showing how each of these elements appears on an actual bill and explains why they might be present or absent from your specific statement.

Practical Takeaway: Look at your most recent BGE bill and identify each major section. Use the guide's explanations to write down what each charge represents in your own words. This simple exercise helps the information stick with you for future reference.

Reading Usage Patterns: How Your Consumption Shows Up on Bills

One of the most important sections of the BGE bill payment guide covers how usage is measured and reported. Your gas usage is measured in therms, with one therm equaling approximately 100,000 BTUs (British Thermal Units) of heat. Your electric usage is measured in kilowatt-hours, or kWh. BGE determines your usage by reading your meter each billing cycle, which typically spans 28 to 35 days depending on meter reading schedules.

The guide explains that BGE has modernized its metering with smart meter technology across most of its service area. Smart meters allow for more frequent readings and can provide customers with detailed usage information through online portals. If you have a smart meter, you may be able to view your usage data hourly or daily, which can help you understand which activities or times of day use the most energy. For customers without smart meters, traditional monthly readings provide your usage information.

Seasonal variations have a major impact on your usage and bill amounts. According to BGE data, residential customers' gas consumption typically peaks in January and February when heating demands are highest. In January, the average residential customer uses around 80-100 therms compared to about 5-10 therms in July. Similarly, electricity usage peaks in summer months around June through August when air conditioning runs frequently, compared to lower winter usage (excluding electric heating).

The guide walks through how to calculate your own usage rate and compare it to similar households. This helps you understand whether your consumption is typical or whether changes in your bill might indicate new habits, equipment changes, or efficiency improvements. For example, the guide provides examples of usage trends from households that added insulation, replaced HVAC systems, or changed thermostat settings, showing how these actions appear as usage changes on bills over time.

Practical Takeaway: Record your meter readings from the past 12 months of bills. Create a simple chart showing your usage by month. This visual representation helps you see your personal usage patterns and understand which seasons drive your higher bills.

Rate Structures and How They Affect Your Costs

BGE offers several different rate structures and service plans, and understanding which one applies to you is key to understanding your bill. The most common residential plan is the standard tariff, which charges a set rate per kWh for electricity and per therm for gas regardless of time of use. However, BGE also offers time-of-use rates in some areas, where the price per unit varies depending on what time of day or season you use the energy.

Time-of-use rates typically charge higher prices during peak demand periods (usually late afternoon and evening on weekdays) and lower prices during off-peak times (typically nighttime and early morning, plus all day on weekends in some plans). For customers who can shift their energy use to off-peak times—by running laundry, dishwashers, or pool pumps during cheaper hours—time-of-use rates may result in lower overall bills. However, customers whose usage is concentrated during peak times may pay more under these plans compared to standard rates.

BGE also offers the BGE Budget Billing program, which is informational material about options that may be available. This program averages your expected annual energy costs and divides them into equal monthly payments, making budgeting more predictable. The guide explains how this program works and notes that while it doesn't change your total annual costs, it does change when those costs are spread across the year. During low-usage months, you pay more than your actual consumption; during high-usage months, you pay less than your consumption. An annual true-up reconciles any differences.

The guide provides information about how rate changes work. BGE's rates are regulated by the Maryland Public Service Commission, and rate cases can result in changes to the charges shown on your bill. The guide explains the general timeline of rate cases and notes that information about rate changes is typically sent to customers in advance, allowing you to understand when and why your per-unit rates might increase or decrease.

Practical Takeaway: Review your bill to identify which rate plan you're on. Visit BGE's website to compare how your current plan's charges compare to other plans that may be available in your service area. Understanding your options helps you make informed decisions about whether a different rate structure might better match your usage patterns.
