    A substation is an integral part of electrical generation, transmission and distribution system. It is an assembly of equipment in an electric power system through which electric energy is passed for transmission, transformation, distribution, or switching. Substations may be owned and operated by an electrical utility or by large industrial or commercial customers. Generally substations are unattended, relying on SCADA for remote supervision and control. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. Substations generally have switching, protection and control equipment and transformers. Substations may be on the surface in fenced enclosures, underground, or located in special-purpose buildings. A grid station is actually a point in the chain of electricity transmission and distribution where power is directed onto the power lines and transformers before it reaches the consumer. In Pakistan, National Transmission and Dispatch Company (NTDC) has control over all properties, rights, assets, obligations and liabilities of 220 KV and 500KV grid stations and transmission lines network. This project deals with 220KV to 132KV under construction Gas Insulated Switchgear (GIS) substation located at Shalamar town, Lahore. This project will be first of its kind because mostly the analysis done before was on 132KV to 11KV substation. Following are objectives of this project. Things to know about the project are written below This project is funded by JICA(Japan International Cooperation Agency) This project is conducted by NTDC (National Transmission and Despatch Company) so it is acting as a client. Contractors of this project are PEL (Pak Elecktron Limited) and NEIE (New England Industrial Engineering) Consulting firm hired for the designing of this project is BARQAAB BOD NTDC approved to award the subject of contract to manufacturers on 21 may, 2010 Notification of contract was issued on 24 may, 2010 Supply from Mangla power plant is taken at 220kv Kala Shah Kaku Substation From 220kv Kala shah Kaku NTDC had laid transmission lines to 220Kv Ravi Road Substation Between 220kv Kala Shah Kaku Substation and 220kv Ravi Grid Station a transmission line is drawn out to 220kv Ghazi Road Grid Station & 220kv Shalamar Town Grid Station 220kv Shalamar Town Grid Station and 220kv Ghazi Road are connected via a transmission line 220 kv Kala shah kaku, Ravi, Ghazi and Shalamar Grid Stations makes up an interconnected system
