But Baltimore County resident Michelle Breau says she soon discovered the deal offered by the Constellation vendor wasn't all that she believes she was promised.
Feeling deceived, Breau says, she tried to get out of the contract within the three-day cancellation window guaranteed by state law, but found it wasn't easy. So she filed a complaint last month with state energy regulators.
Breau believes she was misinformed.
"If had the correct information, then I would have never gone through with it," she said.
As the number of Maryland residents who switch to alternative energy suppliers has grown in the last two years, so have concerns about marketing and sales tactics. The state Public Service Commission, which oversees the power industry, received 552 consumer complaints against power suppliers last year, up from 316 in 2010.
The PSC regulates third-party suppliers, and Maryland laws provide protections for consumers. Still, some suppliers have been fined for operating in Maryland without a license, and the state energy regulator has accused others of misleading marketing practices.
Industry representatives say they take customer complaints seriously. "In order for this to thrive as a market, we have to make sure we do this right," said Robert Barkanic, the state chair for Maryland, Delaware and District of Columbia at the Retail Energy Supply Association, which represents 20 suppliers, including Constellation.
The state deregulated its energy market more than a decade ago, but only recently have residential customers have begun shopping around to find better deals with suppliers other than their utilities.
Two years ago, only 5 percent of the state's nearly 2 million residential customers got their electricity from a third-party supplier. By October 2011, the most recent month for which data was available by the PSC, the portion had climbed to almost 20 percent.
In Baltimore Gas and Electric's service territory, more than one in four customers have switched to an alternative supplier. BGE serves 1.1 million residential customers in Baltimore and surrounding suburbs.
Paula Carmody, who represents residential utility customers in Maryland as the state People's Counsel, said her office is seeing more door-to-door and telephone solicitations from suppliers. "That increases the opportunity for problems to occur," she said.
The Public Service Commission has initiated cases against some companies for what it says are deceptive marketing practices.
Last year, the commission fined Connecticut-based North American Power and Gas $100,000 for making misleading advertisements and ordered the supplier to suspend all telemarketing activities in Maryland. A separate investigation into Viridian Energy for alleged deceptive marketing practices is pending.
Barkanic, of the Retail Energy Supply Association, noted that the number of complaints last year represented less than 1 percent of the almost 390,000 Maryland residential customers who buy power from alternative suppliers.
"We want to make sure we address every single one," Barkanic said. He said the group has a set of principles governing marketing practices.
The trade group would also like to see more programs to explain choices to consumers. A Public Service Commission working group recently recommended an overhaul of the agency's website to develop an educational campaign, including creating a cost calculator to help consumers assess the impact of different deals.
Carmody, the People's Counsel, said consumers should not feel pressured to respond to salespeople or sign a contract immediately when they are solicited by phone or in person. She suggests that consumers request price and other contract terms in writing "so that they could look at it at their leisure."
Third-party suppliers must be licensed by the Public Service Commission, and some jurisdictions, such as Howard County, require door-to-door salespeople to obtain peddler's licenses.
The Office of People's Counsel provides a consumer rights handbook for electric choice on its website. The Retail Energy Supply Association also has a brochure.
Constellation said Breau's experience was not typical. Spokeswoman Maureen Brown said company records show that two complaints related to door-to-door sales were filed with the Public Service Commission as of June.
The PSC reported 64 complaints of all kinds against Constellation and BGE Home in 2011, up from 27 the year before.
Constellation has acquired three companies in the past year to expand its business of selling power in states where residents can choose their electric suppliers. That business now has 1.1 million retail customers in Maryland, New Jersey and Illinois, among others.
The company, which is trying to sell itself to Chicago-based Exelon Corp., uses two vendors for its door-to-door marketing efforts in Maryland.
Brown said Constellation salespeople go through background checks and extensive training and must pass a written certification test. The company uses a third-party vendor to verify sales and also follows up with another customer satisfaction call.
"It's fair to say that we would like to have 100 percent customer satisfaction, and we're certainly committed to that," she said, adding that the company would work with Breau to address her complaint.
But "like any company, we do have instances where the sales transaction has elements that are not to the customer's satisfaction or where the particular standard of training was not executed properly," Brown added. "We can't claim perfection. We could certainly learn from all these experiences and try to get better."
Breau, who works in health care sales, agreed to sign up with Constellation and BGE Home on Dec. 19 based on information she said was provided by the sales agent.
But after reading through the paperwork the next day, Breau said she realized that BGE Home's natural gas price was higher than BGE's, so she attempted to cancel the deal for both electric and gas supply immediately.
While she was able to easily cancel the electric portion, Breau said she was told by BGE Home that it could not guarantee that the contract would be canceled by the Jan. 1 start date. Breau then filed a complaint with the Public Service Commission.
Last week, the commission forwarded Breau a letter from BGE Home, which said she would be switched back to BGE as her natural gas provider on Feb. 1. BGE Home would reimburse Breau for any charges exceeding what she would have paid through BGE in January, according to the letter. Breau would also receive a $50 gift card.
In the letter, BGE Home said it would use Breau's complaint to "educate our outside sales staff to avoid any customer issues or concerns moving forward."
Still, Breau said she was disappointed with her experience.
"I could not imagine a corporation like Constellation Energy would conduct business in this matter," she said.
For your protection
What you should know when you get a call or solicited at home:
•Ask for ID. Door-to-door salespeople must identify themselves and the companies they represent. Some jurisdictions, such as Howard County, also require sales agents to get a peddler's license.
•Ask for written materials and a contract. Salespeople must provide you with a copy of a contract with the company name, date and address. You must sign the contract.
•You have the right to cancel the agreement within three business days of the transaction. The sales agent must provide a Notice of Cancellation form.
•In telemarketing solicitations, the supplier must record the conversation to get your consent for a contract.
•The supplier also must disclose terms of the contract during the call and send you a written agreement within three days.
