been issuing a bit of capital in recent years, not getting the best return on equity at this point. the yield is also pretty average. in 2009 they retained 6.6b in profits and have only been generating an average return of about 6-7% for the 3 years to 2012(not much better than a savings account). wouldn't recommend it as a long term investment. unless you're planning to buy on the result for a trade, then i have no idea.
an interesting thing i read about energy prices recently was that they are by law linked to cost/value of the electricity generating assets. therefore, if origin/any other supplier unneccesarily incurs capital expenses on their stations, they can bump up their power prices.
