  • Reliable power for a remote mine

    ...upply local communities. A planned mine expansion would require additional power, and hence new generation capacity. Providing additional power would have to address the reliability of the local network, which was already under strain from growth in demand from both the mine and the community. This case outlines how we helped the mine manager think about the risks and opportunities associated with the power system upgrade. The purpose was to suppo...

  • Gas-fired power station cost and schedule uncertainty

    ...of the construction had already been completed. A primary function of the power station was to service a power supply agreement with a large industrial customer. The capital and operating costs would be important in final negotiations about the power tariff, as well as determining the profitability of the plant for our client. Commercial arrangements had been agreed with the customer and preliminary contracts were in place. The customer was expan...

    ...We conducted a safety integrity level analysis of the concept design for a power station burner management system. The Koniambo Nickel Project in New Caledonia included a coal fired power station with 2 x 160 MW fluid bed boilers and steam turbines plus 2 x 80 MW diesel-fired combustion turbines; we conducted technical reviews, focused on technical risk, HAZOP studies, technical compliance with contract specifications, interfaces with the processi...

  • Replacing a high-voltage power line

    ...e proposed for a regional area. The purpose of the project was to: Provide power to existing and proposed energy users in the region, including industrial and mining customers Support the installation of new sources of sustainable power generation, including wind farms. The existing 132 kV transmission lines servicing the area did not have sufficient capacity to meet the increasing needs of the region, so significant network enhancements were requ...

  • Enhancing HV power distribution

    ...al in the long-term. The new mine was estimated to require nearly 100MW of power in its first phase, with an additional 150MW as Phase 2 came on stream shortly afterwards. The power infrastructure connection was divided into 5 sections, summarised in Figure 1 and Table 1. Not all of the components were in the project scope. Approach We conducted a workshop to investigate and model the uncertainties in the cost estimate for the transmission line, f...

  • Reliable power for a remote mine

    ...he owners and operators of a remote mine to examine the reliability of its power supply. There was no access to the regional electricity grid, so the mine generated its own power to meet its current needs as well as those of surrounding communities. A planned mine expansion meant that the power generation and distribution capacity for the plant needed to be upgraded. This prompted the need for a risk assessment. This case discusses the importance...

  • Business case for a wind farm

    ...mon connection to the electricity grid. The central issue surrounding wind power is supply reliability. While the turbines themselves are proven and reliable, wind itself fluctuates so it cannot be relied upon as a base load power source. However, in the proper locations, wind can be an excellent source of cost effective generation into the grid. New technologies are: Increasing the efficiency of harnessing wind power Improving the cost effectiven...
