FRANKFURT, July 9 (Reuters) - Germany needs investments

of around 300 billion euros ($325 billion) by the middle of the

century to equip its power grids for decarbonisation, state bank

KfW said on Tuesday.

"The necessary expansion of renewable energies makes

suitable and flexible transmission and distribution networks

necessary and requires high investment," KfW said at a capital

markets conference at its headquarters in Frankfurt.

"The means for that cannot come from public funds alone but

must for the larger part be mobilised via private investors or

the capital market," it added.
