Final Consolidated Infrastructure Development Framework Version: Budget-Reconciled and Technical Review Edition EXECUTIVE SUMMARY Fiveo1 Energy Holdings, LLC proposes a phased infrastructure development program for Santa Catalina Island focused on renewable generation, battery storage, grid modernization, critical infrastructure resilience, energy management technology, and long-term utility infrastructure support. The program recognizes Southern California Edison (SCE) as the existing electric utility serving Catalina Island and does not assume ownership or operational control of SCE assets, retail service authority, franchise rights, or public utility status. All activities are intended to occur through lawful agreements, approved interconnections, infrastructure partnerships, service contracts, power purchase agreements, storage agreements, and required regulatory authorizations. The project objective is a resilient, financially sustainable, technically reliable, environmentally compliant electric infrastructure platform capable of supporting Avalon, Two Harbors, public agencies, businesses, residents, visitors, water systems, wastewater systems, emergency services, and future electrification requirements. VERIFIED SYSTEM CONDITIONS Santa Catalina Island operates as an electrically isolated system. The island is not interconnected with the California mainland transmission network. Electricity is supplied from local generation resources centered at the Pebbly Beach Generating Station. Historical engineering studies documented approximately: 29.1 GWh annual electricity consumption 5.5 MW peak demand 0.9 MW minimum demand 3.31 MW average continuous load Engineering studies have evaluated future planning scenarios approaching 7 MW peak demand. The historical generation inventory documented in public technical studies included: Six diesel generators totaling approximately 9.4 MW Twenty-three propane microturbines totaling approximately 1.5 MW One sodium-sulfur battery system rated at 1 MW and 7.2 MWh Historical generation nameplate capacity: 10.9 MW Historical total capacity including battery discharge capability: 11.9 MW All future engineering shall be based on verified operating data, equipment condition assessments, dispatch records, and approved planning assumptions.

The plan is structured to operate within existing regulatory frameworks, utilize verified engineering standards, maintain service continuity, preserve public safety, and require documented technical, financial, environmental, contractual, and regulatory validation before any capital construction commitment is authorized. All budget totals in this final version are mathematically reconciled and internally consistent. The Phase 0–1 development authorization is corrected to $5.0 million to $9.4 million, and the total program capital budget remains $70 million to $143 million.
