I recall reading that the regulation of these cycles can cost 1% of the power supply used (sorry, can't find the source link). Another reason for the deregulation may be this:

Big names pony up for power-line broadband Current Communications announced Thursday it had received $130 million in investments to accelerate Broadband over Power Line technology. Current uses BPL technology to provide broadband service that runs across power lines, allowing the potential for a new source of retail Internet service as well as accommodating "smart grid" electric meters for utility companies. "This technology provides utilities with a more intelligent, real-time and secure power grid that should help conserve energy, reduce electricity disruptions and protect critical infrastructure," said Alex Urquhart, president of GE Energy Financial Services.
