A complete illustrated engineering reference for the design of a 160 MW on-site power plant serving a hyperscale data center campus. This book presents a fully integrated design package covering 2N generation redundancy with six 35 MW gas turbines, twenty 10 MW reciprocating engines, a 100 MW / 400 MWh battery energy storage system, dual 230 kV utility interconnections, and a 99.999% availability target. Eleven illustrated chapters guide the reader through every engineering discipline in the project lifecycle: • Chapter 1 — Project Overview & Design Basis: site load profile, design criteria, regulatory framework, and preliminary scoping. • Chapter 2 — Master Site Planning: campus layout, fuel storage, transmission corridors, and infrastructure sequencing. • Chapter 3 — Power Generation Systems: gas turbine selection, combined-heat- and-power integration, reciprocating engine packages, and paralleling schemes. • Chapter 4 — Electrical Distribution: 230 kV switchyard, 33 kV collector system, transformer sizing, protection coordination, and cable routing. • Chapter 5 — UPS & Backup Generation: battery energy storage architecture, static UPS design, diesel standby generation, and transfer switching. • Chapter 6 — Control Systems & SCADA: distributed control architecture, protection relay settings, alarm philosophy, and cybersecurity requirements. • Chapter 7 — Mechanical & Thermal Integration: cooling water systems, waste- heat recovery, fuel gas conditioning, and HVAC for auxiliary buildings. • Chapter 8 — Civil & Structural Design: foundation engineering, structural steel design, seismic analysis, drainage, and paving. • Chapter 9 — Environmental & Regulatory Compliance: air permitting, noise assessment, stormwater management, and environmental monitoring. • Chapter 10 — Reliability Engineering & Commissioning: availability modelling, factory acceptance testing, site commissioning, and performance testing. • Chapter 11 — Design Deliverables & Drawing Packages: drawing register, specification structure, and design governance. Three appendices round out the package: Appendix A lists key applicable standards (IEEE, IEC, NFPA, NERC, ISO); Appendix B provides a 60-term technical glossary; and Appendix C reproduces 70 CADD-quality engineering drawings spanning single-line diagrams, site plans, UPS room layouts, equipment arrangements, protection schemes, grounding systems, and civil details. The book contains over 100 full-colour technical illustration plates — each optimised for on-screen reading — making it an essential reference for power engineers, data center infrastructure designers, project managers, and students preparing for work in the hyperscale computing sector.
