I wouldn't say that they're comparable other than what they're trying to do. Different company, different management, different technologies, etc.. Unlike the one you mentioned, GESI actually has a paper trail of their progress. Its not smoke & mirror PR's like others that tried & failed.
Being that its a utility company, there's a lot of things involved that regular companies don't have to deal with... such as government regulations to sell/produce electricity.
