This study develops and tests a methodology that can be utilized for a reconnaissance level assessment of electric power supply alternatives for medium-scale mining in northwestern British Columbia. The study is organized into four parts. Part one characterizes the public planning framework of the study area. Present and future use trends of the region's natural resources, in particular minerals and energy, are reviewed, and a typology of public preferences for their development is established. Part two carries out a literature-based review of the conceptual basis of normative decision-making. Specific energy project evaluation approaches are introduced. This establishes a theoretical framework for constructing the methodology. Part three presents the energy project assessment methodology. Part four applies the methodology to the RED-CHRIS deposit. Salient features of parts three and four which form the core of the study, are outlined below. Energy Project Assessment Methodology The central part of the study proposes a strategic, reconnaissance-level methodology for evaluating energy supply alternatives for medium-scale mining. Its scope is defined by; a) inclusion of strategic elements such as emphasis on priorities, analytical continuity, robustness, and adaptiveness, and b) adoption of a reconnaissance approach which reflects an intention to accommodate preliminary information at an appropriate level of complexity and comprehensiveness. The essence of the methodology entails three inter-related components: 1) Core Information Environment - Identifies and focuses on defining the energy supply issues for a particular undeveloped mineral deposit. 2) Basic Evaluation Environment - Assesses the viability of potential alternatives through the application of multiple criteria and formal decision-making procedures. 3) Peripheral Evaluation Environment - Assesses strategic information which is independent of the focused problem, but can exert an influence on the outcome of both the core and basic environments. Each component contains strategic data bases and analytical processes that assist the analyst to proceed from initial problem identification to selection of alternatives. Within and between the three structural component information is refined in an iterative fashion. This maintains a current perspective on the problem environment and leads to a more confident appraisal of the favoured energy alternatives for a mineral deposit. Case Study Analysis: RED-CHRIS copper-gold deposit situated southeast of Iskut was selected for a case study application of the methodology. Typical production schedule ranging from 8 to 20 years would require corresponding installed electrical capacity of 7.5 to 23.5 Megawatts. Key points which emerged from an analysis of this deposit's energy supply alternatives form the mine planner's perspective are: 1) Interest groups concerned with planning, developing, or regulating energy supply for RED-CHRIS include: a) Mineral deposit owners whose objective it is to maximize profit b) Societal interests whose objective it is to maximize economic, social and environmental well-being aspects of the project. c) Public policy interests whose objective it is to maximize economic, political, and social welfare within national and provincial energy policy. 2) Energy supply candidates identified and examined, include: diesel-electric, high voltage grid extension, small-hydroelectric, coal and biomass-fired generation, natural gas, peat, geothermal, wind and solar. 3) Comparison of different small-scale energy applications for remote areas is made difficult because of technical, political, and environmental uncertainties. 4) Satisficing and Dominance can be successfully applied from the mine planner's perspective to key decision criteria to narrow the various energy supply alternatives. 5) Small-hydro is the most favourable alternative at this juncture, followed by diesel. Coal-fired generation and biomass are comparable, and may be more favourable than diesel under certain circumstances. Other alternatives are presently unsuitable. General Conclusions: Application of the methodology is limited by the interaction between analytical design, available physical resources, and uncertainty in the operating environment, human values and external decisions. The methodology appears sufficiently robust and comprehensive to be adapted to other deposits in the region. Commonly shared information requirements combined with the iterative nature of information processing, can be used to reduce the resource demands and improve the efficiency of subsequent applications. Finally, it is recommended that the value sensitivity of the methodology be tested by applying it from more than one perspective to the same deposit. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Thesis (MBA (Business Management))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: The world today is facing many energy challenges such as power outages experienced internationally and in South Africa. The demand for energy is constantly increasing and is creating environmental problems such as climate change, which is presently a major concern to society. This study is an attempt to establish how energy saving mechanisms such as the elimination of non-essential power can add economic value within the mining industry. This paper examines the effect of non-essential power and how it could assist companies to reduce their energy consumption, aid local power utilities in a crisis and maintain normal production levels. This research report was based on an investigation for power saving opportunities at a mining company during a power crisis. The paper looks at energy efficiency and the barriers to the adoption of energy savings. Companies in general do not have a structured way of addressing non-essential power saving. Companies are not aware of the value such initiatives could have on corporate responsibility and sustainable reporting. The benefits of energy efficiency and nonessential power on the triple bottom line are not clearly documented in literature. When comparing the impact of non-essential power on the triple bottom line, it became obvious that further research is required in order to prove whether it influences the social aspect. The impact of power generation on the global environment has not been clearly calculated and linked to the value of saving power. The literature review highlighted that companies are focusing on long-term initiatives instead of smaller initiatives, which requires less effort. During the investigation of the mining company, it was found that not much effort was made during the design stages in separating the electrical circuits from non-essential and essential power. The author concludes that switching off non-essential power held economic and environmental benefits for the mining company. The author therefore concludes that switching off non-essential power impacts positively on the economic and environmental part of the triple bottom line. It was found that the elimination of non-essential power is easy to implement with minimum investment and effort. Furthermore, the savings from these initiatives could easily be measured to calculate the return on the investment. / AFRIKAANSE OPSOMMING: Ons kry deesdae al meer te doen met uitdagings soos internasionale en plaaslike kragonderbrekings in die energiebedryf. Die aanvraag vir energie verhoog deurlopend en veroorsaak omgewingsprobleme soos klimaatsveranderinge, wat ‘n groot bekommernis is vir die samelewing. In hierdie studie word gepoog om vas te stel hoe energie besparings meganismes soos die eliminering van nie-noodsaaklike krag ekonomiese waarde kan voeg tot die mynboubedryf. Die uitwerking wat nie-noodsaaklike krag het en hoe dit maatskappye kan help om kragverbruik te verlaag terwyl produksievlakke steeds gehandhaaf word, is hier ondersoek. Plaaslike kragvoorsieners kan ook baat vind hierby in krisistye. Hierdie navorsingsverslag is gebaseer op ‘n ondersoek van krag besparings geleenthede by ‘n mynmaatskappy gedurende ‘n krisistydperk van kragonderbrekings. Die verslag kyk na die doetreffendheid van energieverbruik, asook na die hindernisse wat ondervind word in die inwerkingstelling van energie besparings inisiatiewe. Maatskappye het in die algemeen nie ‘n gestruktureerde metode om die probleem rakende nie-noodsaaklike krag aan te spreek nie. Hulle is nie bewus van die nut wat sulke inisiatiewe kan hê op korporatiewe verantwoordelikheid en volhoubare verslaggewing nie. Die voordele wat energiebesparing en die eliminering van nie-noodsaaklike krag op die ekonomie, gemeenskap en omgewing het, word nie duidelik geboekstaaf nie. Verdere navorsing moet gedoen word om die impak van energiedoeltreffendheid en nie-noodsaaklike krag op die sosiale aspek te bewys. Die uitwerking wat kragopwekking op die globale omgewing het is nog nie bereken en verbind met die waarde daarvan op kragbesparing nie. Die verslag beklemtoon dat maatskappye fokus op langtermyn inisiatiewe in plaas daarvan om te kyk na kleiner inisiatiewe wat minder moeite en tyd sal verg. Die ondersoek by die mynmaatskappy het getoon dat daar nie klem geplaas is op die onderskeiding tussen nie-noodsaaklike en noodsaaklike krag met die installering van die elektriese stroombane tydens die ontwerpstadium nie. Daar is gevind dat die afskakeling van nie-noodsaaklike krag ekonomiese en omgewingsvoordele vir die maatskappy inhou. Daar is tot die slotsom gekom dat die afskakeling van nie-noodsaaklike krag in die algemeen dus ‘n voordelige uitwerking het op die ekonomie en omgewing. Dit is maklik om te implementeer met minimum moeite en belegging. Die besparings deur middel van hierdie inisiatiewe kan ook maklik gemeet word om die opbrengs op die belegging te bereken.
