An extra 310 miles (500km) of lines is needed over the next five years in central and southern Scotland.
As part of its investment, SP Energy Networks will begin work to build 12 new substations, upgrade 450km of existing circuits and 87km of overhead lines and replace 35km of underground cable by 2031.
The investment also includes two new subsea electrical superhighways off the east coast of Scotland.
A growth in renewable generation in Scotland is expected to far exceed the amount that can be consumed, and so much of it will have to be exported to England.
Mr Anderson said: “We need to get the electricity moving around the country if we want the whole of the country to benefit from this.
“Some of this will be strengthening existing lines, putting more capacity through them, then there are also new lines.
“For any community being impacted there will be a engagement process, looking at what we’re doing, how we’re doing it, when we’re doing it and where the line goes, and where the substation goes.
“All the local communities will be involved in that debate to get this done in a way that is a beneficial to everybody.”
