The energy firm said the new roles are in addition to the 1,500 posts it announced last year. However, Scottish Power said the jobs are dependent on Ofgem putting in place the approval and funding regime for the extra spending.
Ignacio Galan, chairman of Scottish Power, said: “We are investing £4 billion between now and 2014 in the UK, representing 40 per cent of our global investments, with two-thirds of this investment planned for Scotland.
“On the back of our long-term investment plans, we are creating 4,000 jobs in our networks business alone, which will see our company continue to grow and help to boost the Scottish economy.”
