BOSTON — An analysis of the state’s aging natural gas pipelines has found that they are riddled with about 20,000 potentially dangerous and environmentally damaging leaks which may cost ratepayers more than $1 billion.
The analysis was conducted by Home Energy Efficiency Team, a Cambridge nonprofit that mapped the leak data submitted by the utilities under a new state law.
Some leaks are decades old.
Home Energy President Audrey Schulman tells The Boston Globe the leaks are potentially explosive, harm the environment by releasing greenhouse gases, and threaten human health.
Utility companies are addressing the problem.
An Eversource spokeswoman says the company plans to repair about 50 miles of pipe per year.
A National Grid spokeswoman says the company plans to spend $2.4 billion over the next five years repairing pipes.
