Back in 2002? I don't think they separated generation and delivery for most utilities, at least in the US. In 1996, federal regulators made it mandatory for utilities with delivery infrastructure to accept generators' electricity on fair/nondiscriminatory terms, and gave them some time to implement policies. Then, the actual generators started negotiating deals, but the early days were a bit chaotic, with issues in California with rolling blackouts, then the Enron bankruptcy, and then generators actually entering long term contracts with some price stability in the early 2000's.
For a typical residential customer who didn't go out of their way to look for side deals with generators, they wouldn't have needed to see their bills be segmented out into generation and delivery, since most of the utilities still already had long term contracts (or owned their own generation facilities) still in effect from before the regulatory reform.
Personally, I didn't see those numbers separated out on my bill until around 2009. And I remember my electric bill in 2000-2005 being roughly 10 cents per kwh, flat rate.
Yeah that was the real problem with hot swappable discs. The kids who actually physically performed that operation were often too impatient and careless to put the disc somewhere safe from scratching, because they wanted to immediately get back to playing.
