The authors discuss a promising high-efficiency power generating technology, the steam-injected gas turbine (STIG). This is a variant of the simple gas turbine wherein steam recovered in a turbine exhaust heat recovery steam generator is injected into the combustor to augment power output and efficiency. The turbine is shown to have a number of desirable characteristics that make it especially relevant today to a utility industry facing a planning crisis. After a review of the uncertainties in utility planning, developments leading to practical STIGs are summarized. Potential central station applications and institutional issues are also discussed.
