Te globl energic sector accounts for tha largeset share of greenhouse gas emissions, plating the electrical grid at the center of te climate electricety demand rises due to electrification of transport, heating, and industry, the need to decarbonize supply is urgent. Power system geers are te technical architekts and operators manageming this transformation.

Te Evolving Mandate of tha Power System Engineer

Te traditional mandate of a power system engineer focused on predicable, unidictional power flow from large centrald generators to end users. Te net- zero transition fundameny disapts this model.

This shift exaps adopting probalistic risk ement over deterministic planning. Power systematic planners today are systemators, date, date, data scitate sciners.
