FOREWORD I2I

This document “KOC Standard for Electrical Supervisory Control and Data Acquisition
(E-SCADA) System for Substation” (KOC-E-027, Rev. 2) is intended to provide the
minimum requirements for E-SCADA System to be installed at various KOC Facilities in

incorporation of Energy Conservation measures (Metering & Monitoring Energy Consumption),
Information Security requirements, revisions of relevant International / National Standards and
latest technological developments in this field.

This Standard has been approved by the Standards Team in consultation with the ESTC
Sub-Committee (Technical) for use throughout the Engineering and Operational Functions of
Kuwait Oil Company (K.S.C.).

This Standard sets out to achieve the following objectives:

a) To provide technical guidance and establish the base document for developing project /
equipment specifications for Electrical Supervisory Control and Data Acquisition
(E-SCADA) System with a view to achieve uniformity, quality, reliability and efficiency in
an economical manner.

b) To assist the designers by providing technical information and engineering practices for
establishing the basis for E-SCADA System to be installed in electrical Substations to
