Re: Is it a losing battle ?
Integrated generator-suppliers don't have any real advantage, and in fact three of the larger suppliers are at various stages of selling or closing all of their upstream generating assets (one announced, one inevitable, and one an "emergent strategy". Funnily enough there's not a big queue of buyers.
Sort of proves the point that what started out as a market with several players is consolidating into a few big players, who were big in the first place, just as we're seeing with the MNO's. [Aside: Three might not have been 'big', but Hutchinson Whampoa...]
