We have collected Standard Offer Service (SOS) price information for each major local electric company, as well as electricity supply companies who currently offer service to residential consumers in each area. The attached Electric Suppliers Price Chart shows price information for Standard Offer Service offered by the local electric company and the publicly available price offers by electricity suppliers for that service area. We also have noted whether other fees are charged and the length of the contract.
How to Use the Price Comparison Chart
The purpose of this guide is to give you some general price comparison information if you are interested in buying electricity supply from a company other than your local electric company. The chart includes the following price information:
- The “weighted average” for SOS offered by each major local electric company
- The actual SOS summer (June 1-September 30) price
- The actual SOS non-summer (October 1-May 31) price
- The publicly available current price offers of electricity suppliers who we believe are making offers to new customers in the service territory of each company.
The prices listed in the chart include the price for both generation and transmission. The prices on the chart do NOT include other charges, such as the distribution rate, taxes and other surcharges on the local electric company bill. Those charges are paid by all customers, whether you are a Standard Offer Service (SOS) customer or buy your electricity from an electricity supplier.
The charts also include the basic residential rates under which the majority of Maryland residential customers are served. They do not include other special rates, such as time of use rates which vary based on time of day and by peak usage.
What is Standard Offer Service?
Standard Offer Service (SOS) is the electricity supply service provided by your local electric company if you do not choose to buy electricity supply from an alternative electricity supplier.
What is the “Weighted Average?”
The “weighted average” (WA) is provided to you by your local electric company, and is listed on your electric bill. It is the average rate on an annual basis for SOS service from your local electric company. The WA is a 12 month blend of summer and non-summer SOS rates from June 1-May 31. The current WA has been calculated based on the utility’s wholesale contracts. The utilities have not yet contracted for all the power they will need after May 31. Therefore, we can not say what the SOS price will be more than 12 months in the future.
Why do you Include Summer and Non-Summer SOS Rates on the Chart?
There may be a mismatch in time between the annual "weighted average" (WA) and the term of supplier offers. As a result, the comparison between the annual WA and the supplier price offer may not be helpful. For that reason, we are now including the actual summer and non-summer SOS rates that are known at this time in our charts, in addition to the WAs for each company. The actual summer and non-summer SOS rates are the rates that are blended and included in the annual WA.
This Price Information is for Comparison Purposes ONLY and is Subject-to-Change at any Time
We offer this price comparison chart as a guide to give you a general idea of the types of offers currently being made. We have tried to gather accurate information, but since OPC is not the source, we cannot guarantee its accuracy.
- The names of the active suppliers are the companies listed on the website of the Maryland Public Service Commission (PSC) and may change at any time.
- The SOS price information is from the rate schedules for each local electric company that are approved and on file with the PSC.
- The PTC is calculated by your electric company and appears on your electric company bill.
- The price offers and contract terms of the electricity suppliers were obtained from the websites of those companies. The companies may also have other time-limited offers or make targeted offers to certain customers.
- You will be charged the supplier price beginning about 2 to 6 weeks after you sign the agreement.
THE OFFERS AND PRICES ON THE CHART MAY CHANGE AT ANY TIME. You should ALWAYS contact the electricity supplier directly to obtain the most current price offers and all of the contract terms, and read our CONTRACTING GUIDE before entering into an agreement with a supplier. THE PRICE TO COMPARE MAY ALSO CHANGE IN THE FUTURE.
Renewal or Clean Energy Offers
Many of the offers from electricity suppliers are for electricity that is wholly or in part renewable or clean energy, such as wind energy. If a significant portion of the electricity supply offer is for energy generated from renewable sources, the price typically is higher than the price for Standard Offer Service.
Some electric suppliers also offer Green Tag or Renewable Energy Credit (REC) products, which are available as an add-on to your current electricity supply cost. We have NOT included these products in the chart. These products are available for an additional price, above the price of the electricity supply, and represent the additional cost associated with renewable or green electricity generation. If you are interested in these products, you should ask about them when you contact the electricity supplier. You may also get more information about renewable energy, Green Tags, and the Green-e Renewable Electricity Certification Program from the Center for Resource Solutions at 888-63GREEN.
