Environment and sustainability
Introduction
New Zealand’s power intend to build a 66kv/11kv substation near MIT Manukau campus in Auckland. The proposed substation will have 66kv high voltage incoming line with several 11kv feeder lines going out. The incoming 66kv voltage will be stepped down to 11kv voltage through two 23MVA transformers [1]. The stepped down voltage will be evacuated and sent through the existing distribution line via underground cable. The built structure will take 3500m2 of the site which include the transformer, switchgears and the bus bars. There will be a switching control room of size 10*6.3*5m, about the size of a double garage. The site will be finished with natural colors (brown and green).
Objectives
New Zealand’s power key activity is to design and develop substation to supply energy for MIT Tech Park.
The main objective of New Zealand’s power is to ensure that supply of electricity is secure, reliable and affordable, service levels are met and maintained and investment is financially sustainable for short and long-term. [2]
This design and installation plan sets out overall framework for how New Zealand power addresses the needs through ensuring a robust approach in developing a substation.
Purpose
New Zealand’s power undertake projects to ensure that service levels, stakeholder interest and regulatory requirements are met for its electricity distribution networks.
The plan illustrates how New Zealand’s power achieves this by outlining management plan, budget plan, objectives, specification and strategies adopted by NZ’s power for its substation.
Technical specification
Two three phase 23MVA transformers will be used to step down 66kv to 11kv, which will then be carried by 4 feeder lines. As 66kv line enters the substation it will pass via C.T and V.T for protection purposes. These transformers will be protected by surge diverters in case of lighting strike, connected in series with transformer. Two 11kv SF6 circuit breaker will be installed in which protects the assets, in case of any faults with in the system occurs. As nursing department is to be considered as well, there will be one harmonics filter supplying pure active power to the buildings as some of the equipment’s are very sensitive to distorted signals in the system. All the voltages and currents will be closely monitored with SCADA software. For inspection purposes advanced mobility tools will be running on tablets which increases productivity.

Project scope management plan
The scope of the project was developed by data collection process. A thorough analysis was done on client’s feedbacks and the current employees. From that information, project team developed the management plan.
This project includes designing and installation of 66-kv/11-kv substation which can supply the load to the tech park.
The project manager, client and the employees will play a key role in achieving the deliverables. As such, team member, project manager and client should know their duties. The table below outlines key roles of the personnel:

Work Breakdown Structure (WBS)
The project is broken down in 5 phase namely; designing, site preparation, procurement, installment of equipment and cleanup and commissioning. Each of this phase is then sub divided into other tasks which will require no more than 40 hours of work a week per worker and not less than 4 hours.
The diagram below shows how the structure will be divided and sub divided for the deliverable of the project.
Time management plan
Time management plan is developed by skillful people and from past experiences. Employee’s feedback was also taken into account when making the time plan. The project will be completed in four months, including all other factors which can cause delay to the project.
All the team player plays an important role in achieving the deliverables. Project manager will keep the record of the progress of the project and will pass over information to the employees and the clients whenever required. The table below shows how the task will be done:

Cost management plan
The cost management plan will define how the money will be used throughout project life cycle. The Performance of the project will be measured using Earned Value Management. The following metrics will be used:
- Schedule variance(SV)
- Cost Variance(CV)
- Cost Performance Index(CPI)
- Schedule Performance index(SPI)
The ratio for CPI and SPI are set to be 0.9 and 1.1, any ratios above or below the margin are questionable and the project manager will try to communicate the issue over the monthly meeting. In the case of extremes the project manager will come up with a Cost Variance Corrective Action Plan.
Various cost estimating techniques have been used to come up with a cost effective plan.

Quality management plan
There is no quality management plan drawn up for this project. All the quality checks will be conducted by the project manger.
Risk management plan
The approach to the risk management plan is a methodological process by which the project team identifies and access any risk involved. Every effort will be made to proactively identify risk in order to develop and implement mitigation strategies. The most likely and high impact risk had been taken into account when developing the time management plan.
On the completion of the project the project manger will analyze the risk and the risk management plan. Based on this analysis the project management will identify and make improvements on how to avoid them in future projects.
Change management plan
This the general change management plan for the company which is implemented on each and every project that we handle. The list below shows how the plan works:
- Identifying the need for the change
- Log the change in the logbook
- Evaluation of the change
- Submit change request to the client
- If the client aggress on the change, project manager will implement the change.
Anyone from the client, stakeholder, project manager or other workers involved in the project can submit their change.
Ethical issues
This project will adapt with strong New Zealand code of ethics set up by engineering New Zealand.
All the employees will work with integrity, this will be achieved by assessing the characters of the employees.
Project manager will be required to report to stakeholders regarding any conflict of interest.
Employees will be required to act professionally and with the standards, this will be achieved by training employees.
Project manager are required to provide clients with fair, honest, complete and accurate information of the progress or any conflicts of interest in a timely-manner.
All the team members are required to maintain privacy of the client and the project unless granted permission to do so.
All members are required to take responsibility for their own action.
All members are required to interact with team and clients in a professional manner by respecting their culture or ethics. This will be achieved by educating project manager about the community.
Environment and sustainability
No harm will be caused to the local community and the bio diversity nearby during the course of this project. If required we will seek community feedback and explain them the importance of the substation. All the resources will be used effectively to complete the project on time and not exceeding the budget. Whenever required toolbox will be held to let the employees know about the potential hazard and how to avoid them.
