A 1987 BI No. 304, entitled “Transmission Plant--
Systemwide--Miscellaneous--1987”, approved in 1986, budgeted $9.8
million for transmission lines, substations, relay projects, and
miscellaneous projects. ER No. 3276, approved in late 1987/early
1988, authorized the expenditure of $738,140 to replace five 230-
kV transmission breakers at the St. Lucie plant. On the basis of
a study by the system planning department, the ER states that the
then-existing breakers would become overstressed because of the
500-kV transmission expansion. A 1989 BI No. 267, entitled
“Transmission Plant--Systemwide--Miscellaneous--1989”, approved
in 1988, budgeted $23,456,000 to, inter alia, upgrade and replace
various transmission lines. ER No. 5334, approved in late
1988/early 1989, authorized the expenditure of $1,192,967 to
install one 500-kV bus tie breaker at the Poinsett substation.

$3,401,908 to install a 500-kV 2 breaker terminal.80 A 1988 BI
No. 264, approved on October 15, 1987, entitled “Transmission
Plant Systemwide Miscellaneous--1988”, budgeted $12,045,000 to,

three locations. ER No. 3216, approved in late 1987/early 1988,
authorized the expenditure of $1,257,310 to add two 230-kV MVAR
80 Mr. Sanders testified that this expenditure was “an
