MTM is committed to minimising the impact of its activities on the environment. Accordingly the design of the Standardised Modular s shall source and promote a product range which will minimise its environmental impact over its entire asset life cycle, including construction, ongoing operation and disposal. In particular, MTM has a focus on reduced electrical losses in its substation equipment. 8 Type Approval The Modular s shall be subject to MTM s type approval process. 9 System Requirements The system requirements for the following systems will be specified separately: High Voltage Distribution System (22kV) Essential Services Distribution System (2.2kV, 1.0kV and 650Vac) Industrial Power Supply System (22kV,11kV, 6.6kV) 1500V DC System Refer to ELECTRICAL NETWORKS PRINCIPLES AND PERFORMANCE (L1-CHE-STD- 015) for the definitions. 10 Functional Requirements The functional requirements of the, dictated by the System Requirements, will be specified separately for each Standardised Modular and its individual location on Form Number L4-CHE-FOR-016.

9 11 User Requirements 11.1 Design Criteria The following objectives should be realised: Through standardisation of layout and design achieve improved cost effectiveness in construction, installation and ongoing maintenance Reduced delivery time Improvement on the current functionality, reliability and maintainability Avoidance of design change from location to location. More flexibility and reduced costs of future upgrades or additions. The configuration of modules shall be able to be expanded or altered with the minimum of works, by the installation or removal of a module/s and the necessary interconnections. The footprint of each Module shall be optimised, to ensure a minimum size is realised whilst achieving required clearances and maintainability of equipment. The interfaces between the standard functional blocks and between the blocks and external connections will be managed by MTM to be consistent, which will help create a Plug-and- Play setup that will minimise Project Management and external design costs as far as practicable. The achievement of standardisation may encompass off site construction and testing techniques and transportable plant to provide the opportunity to minimise site installation and commissioning time, on site civil works and the required footprint. If this technique is used, the Standardised Modular shall be transportable in a non-divisible assembly if possible. The Head of Engineering/Electrical may vary the extent of site building, installation and testing works subject to site conditions, cost, maintainability, constructability and other factors Process for Module Determination of Module Configuration Owing to the variable nature of the configuration of the Modules, it is vitally important that the system requirements are determined in the planning stage of a project. The process for determination of the system and functional requirements and ongoing design shall follow L1-CHE-MAN 01. The effective and efficient management of the procurement of equipment is dependent on these processes being followed, particularly for protection and control and other electrical system interfaces.
