AUGUSTA — The chairman of Central Maine Power’s corporate parent confirmed his commitment to a $1.4 billion upgrade to the state power grid during a meeting today with Gov. John Baldacci.

Ignacio Galan, chairman of Spanish utility Iberdrola, met with the governor today at the Blaine House, the governor’s residence in Augusta.

The meeting came a week after the Maine Public Utilities Commission approved the CMP project that includes 440 miles of new and upgraded high-voltage lines, as well as five new substations.

The project will double the backbone of the grid by the time it’s completed in five years, making the grid more reliable and creating capacity for future wind power projects.
