FRANKFURT, Nov 13 (Reuters) - A 55 billion euro ($58.45

billion) investment programme by Germany's biggest power

producer RWE up to 2030 will be kept in principle, but

curbs in 2025 and 2026 mean the sum could be spent later, the

firm's CFO told reporters on Wednesday.

"We will invest 2 billion euros less in those two years. I

don't think we will add those (figures) in later years (up to

2030)," said CFO Michael Mueller after the company announced a

1.5 billion euro share buyback programme and posted better than

expected nine-month earnings, which drove up shares.

"But the total 55 billion as a total programme is an

investment in the transformation of our company and I would

stick to that," he added.
