It is interesting to note that when power prices tumbled at the beginning of the year shares prices in power companies did not fall. In fact rumours of mergers and acquisitions forced some them to remain steadfastly high. International Power for example bashed through the £4 mark with fund managers and traders sighting it as a takeover possibility. Furthermore, Scottish and Southern a company that has doubled in value over the last three years also remains very high.

As oil prices and metal prices continue their summer surge the likes of Rio Tinto and also Anglo American have continued to rise setting new highs as the value of their commodity rises. Power prices do not look like rising dramatically and will continue to follow gas power and emissions prices, but the share prices can lead investors to look at the raw commodity in more detail, and green power shares have rocketed. Clearly some people feel that this market has upside potential.
