A company doing businesses more than five decades in the Triangle could start trading publicly as early as tomorrow in an effort to tap into the "Smart Grid" technology trend and raise more than $250 million on Wall Street.

Elster Group filed for an initial public offering on Sept. 13 and has been negotiating the value of its stock with prospective institutional buyers. Once the financial institutions commit to a price, the shares will begin trading publicly.

Elster is floating 16.2 million American Depository Shares that it hopes will be valued between $16 and $18 per share.
