Introduction
Power and electricity industry fundamentals are often missing among new joiners, analysts, lawyers and finance staff who work on generation contracts, network tariffs or regulatory filings, so meetings with engineers and system operators stall on basic terms and decisions rest on misread figures. This Core Concept programme explains how electricity is produced, moved, controlled, priced and regulated, from volts and kilowatt-hours to plant economics, substations, frequency control, tariffs and renewable integration. Participants prepare a Power System and Sector Briefing for a case utility.
Course Objectives
- Explain voltage, current, power, energy, three-phase supply and power factor when reading plant data, bills and network reports
- Compare thermal, combined cycle, nuclear, hydro, solar, wind and storage plants on role, capacity factor and levelised cost
- Describe how transmission lines, substations, switchgear, distribution feeders and protection deliver supply to customers
- Interpret how system operators balance demand, hold frequency, schedule reserves and restore supply after outages
- Assess utility business models, cost of supply, tariff structures and market arrangements that shape sector revenues
- Prepare a Power System and Sector Briefing that sets out fleet, network, tariff and energy transition issues for a case utility
Target Audience
- Early-career staff in generation, transmission and distribution companies who support engineering, planning or commercial teams
- Analysts in regulatory bodies and energy ministries responsible for reviewing licences, tariffs and performance reports
- Finance, investment and audit staff responsible for budgets, project appraisals or lending in the power sector
- Legal and contracts staff who draft or administer power purchase, connection and supply agreements
- Commercial, customer service and human resources staff in energy companies who need a working picture of the power system

Why Attend This Course
- Leave with a Power System and Sector Briefing for a case utility, tested in a peer challenge session
- Follow engineering, system operation and regulatory discussions without losing the thread on units, voltage levels or reserve terms
- Move in week two from the physical grid to control centres, regulation, tariffs, markets and the energy transition
- Compare how the power sector works with peers from utilities, regulators, independent producers, lenders and law firms
Conclusion
A power sector makes sense to non-specialists once the physics, the assets and the money are seen as one chain. Week one builds that chain from electrical quantities and generation technologies to transmission, substations, distribution feeders, protection and metering, closing with a guided plant-to-customer case. Week two adds control centre operation, frequency and reserves, reliability, power quality, grid codes, safety, utility models, tariffs, market arrangements and renewable integration. The capstone turns both weeks into a Power System and Sector Briefing for a case utility.
