Slightly off topic - the determination of "reliable" normal power can change with time. Look at the Texas area after last winter. Look at New Orleans after the last 24 hours. Just because an area was served by reliable power in the psat, things do change. Have the engineer of record determine if standby power is required. As Craig stated, many factors can influence the decision.
On a personal note, I have specified, designed, installed, tested, and maintained thousands of diesel driven fire pumps systems. Thet do make a good option where normal and or standby power is an issue.
