Funny you should mention that. National Grid announced yesterday that they plan to invest £60billion over the next five years. They will partially fund this with £7billion from investors, and by cutting dividends, and by selling a gas asset. I believe this is double the investment in the previous five years, but I can't find the figures now
I applaud them for not acting like our privatised water companies, which raised money by huge loans which the customers pay the interest on, and handing it out to shareholders, leaving the companies crippled by debt, and underinvested, with filthy infrastructure.
