A green light for usage-based billing at Time Warner Cable.

Time Warner Cable announced its intention to expand its usage-based billing system for broadband beyond southern Texas, and is now considering new pricing tiers that will emphasize usage levels over broadband speeds, according to CEO Glenn Britt.

Appearing at the industry-sponsored Cable Show in Boston, Britt suggested consumers can “save money” opting out of unlimited broadband with its Internet Essentials program, which provides a $5 discount for customers who agree to keep their usage below 5GB per month.  The company is now also considering additional service tiers that will offer different usage allowances at progressively higher prices.

Britt insisted the company will retain the option of unlimited use service, but did not specify whether that would be sold at the same price customers currently pay for the cable company’s Internet service.

Federal Communications Commission chairman Julius Genachowski yesterday told cable industry executives he supports usage-based pricing, making it unlikely the FCC will intervene if companies substantially raise broadband pricing.

In 2009, consumers and elected officials protested the cable company’s earlier experimental foray into usage pricing which would have tripled the price of unlimited broadband service to $150 a month. The company quickly relented after customers picketed the cable operator in Rochester, N.Y., and Greensboro, N.C., in a campaign coordinated by Stop the Cap! The cities of Austin and San Antonio, Tex. also made their opposition clear through public meetings and input from local officials.
