A summary of BGE's residential rate plans

Baltimore Gas & Electric Company offer three main plans for residential customers: the R plan, RL plan, and EV plan.

The first plan, known as Schedule R, is a fixed rate plan where you'll pay different rates in summer and winter. The RL and EV plans are both Time-of-Use rate plans. Time-of-Use refers to a billing system where electricity usage is charged at different rates depending on what time of day the power is used. Such rate plans usually include a Peak period (electricity at a high price) and Off-Peak period (low cost electricity).

A "Tiered rate plan" is a rate plan where the amount you pay per kWh for electricity increases as the quantity of electricity consumed increases. Generally there is a baseline allowance of a certain number of kWhs (kilowatt hours) per month that are charged at a cheaper rate, and then usage above this allowance is charged at a higher rate.

A "Time of Use" rate plan is an electricity plan where the amount charged per kilowatt hour (kWh) is determined by the time of the day and the season of the year in which it is used.

Time-of-Use plans will typically have "peak" periods with higher rates and "off peak" with lower rates.

The idea behind time of use billing is to get customers to use less power at peak periods (when most people use a lot of power). Peak periods put a lot of strain on the grid. This is why time of use billing is being implemented by all major utilities. It is an attempt to encourage consumers to help spread out the load, and thus reduce investment needed to support brief periods of extremely high usage.

If customers can adjust their habits to use appliances at non-peak times they have to potential to significantly lower their electricity bills. Although, as power at peak times is much more expensive, if you continue to use lots of power at peak times your bill could be higher.

Schedule R

This plan has a Delivery Service Customer Charge of $7.90 per month, and this amount will be charged each month regardless of the amount of power you use. The plan also has an Energy Delivery service charge of $0.03147 $/kWh, which will be added onto the total rate.

The "bundled" (total of all charges) rate per kilowatt hour for the Winter season (between the months of October and May) is $0.11365, and for the Summer season (between June and September) is $0.1082. More info on the schedule R can be found here.

How do I work out if I am on the cheapest BGE rate plan for my usage pattern?

To do an exact rate comparison requires collecting your detailed usage data for the last 12 months. This is known as Interval Data and sometimes also called Green Button Data. This data can be used to calculate precisely the rate plan that would result in the lowest cost for your particular needs. Calculating the best rate plan with Green Button Data will give you the most accurate results.

BGE offer 3 different plans to residential customer, and if you don't have an electric vehicle, you have only two plans to from which to choose. The R and RL plans are quite similar price wise, and you should not expect to see much of a difference from switching from one to another, unless you can really limit your usage during peak hours.

How do I get my interval data for the last 12 months?

This data is available from BGE. If you have a login you should be able to download the data. Alternatively you could ring them and ask for them to send you the green button data for the last 12 months. If you own your home and it is a single family dwelling then a really good way to get this data for free is to request solar quotes from local solar companies.

Generally solar offers much bigger savings than swapping plans (as the plans are designed to give the same overall cost to average consumers) and a solar designer will usually need to get this same data to work out what size solar system would cover your bill and to forecast savings accurately for you. Solar companies will usually retrieve and analyze your interval electricity usage data for free in the hope of winning your solar business.

How much can I save per month by swapping to my cheapest plan?

For most people the amount you can save by swapping plans is minimal because electricity plans are approved by the Public Utilities Commission (PUC) and are designed to work out roughly the same in terms of total costs for consumers with average consumption patterns. In most cases savings will be between $0-$10 per month but could be much larger for high energy users or for homes and businesses with non-typical usage patterns. If you really want to save money on your electricity bills, go solar.

Our data shows in Maryland, a 7.78 kW solar system (100% offset of a typical monthly bill of $150) will typically pay for itself in 7 years and 8 months, and has the potential to save more than $50,000 in avoided utility costs over the lifetime of the system (25 years or more). Yes, installing solar could save you $50,000 over 25 years. Going solar has never been easier, and the available incentives make the system thousands of dollars cheaper. There are even option where you can install solar for $0 upfront. Solar is a no-brainer, talk to local solar installers about your options or use this free calculator to see how much solar can save you.
