Major Infrastructure Expansion to Support Regional Growth The Board unanimously approved two significant substation projects totaling over $60 million to address growing electrical capacity needs in the Coachella Valley. The Cook Street Substation (nearly $40 million) will serve the western end of the valley near the new Acrisure Arena, while the Avenue 58 Substation expansion ($23.25 million) will add a fourth transformer to meet unprecedented development demand. Both projects utilize innovative funding structures where cities, counties, and private developers jointly fund construction in exchange for 20-year capacity reservations, with IID contributing up to 20% based on system reliability benefits.
