## 1 Introduction  
This study was conducted to examine viable technologies in the Andean regions of South America where the conventional energy supply is inadequate, with limited or even nonexistent access to electricity and gas [1]. Presently, inhabitants of these areas heavily rely on organic fuels derived from their agricultural and livestock practices, such as firewood and dried animal waste, to fulfill their daily heating and cooking requirements [2]. It is imperative to implement performance optimization techniques that ensure economic, social, and environmental sustainability, while also integrating seamlessly into the traditional way of life and gaining acceptance from the local community [3]. Enhancing the availability of modern energy solutions in rural areas is crucial to addressing the challenges faced by these underserved regions and unlocking development opportunities [4; 5; 6]. The analysis of the introduction of biogas technology has been studied in different areas of the world [7]. However, the Andean zone presents particular atmospheric and raw material characteristics that require specific attention. One of the first steps to assess the viability of the implementation of technology based on gas turbines is to analyze their behavior when faced with new fuels [8], considering that determination methods for contaminants such as siloxane have been developed [9]. A low-cost process for emission abatement of biogas internal combustion engines has been developed, and this should be considered [10]. The economy of most Andean communities revolves around self-sufficient agriculture and family farming [11; 12; 13]. Their agricultural practices are predominantly agropastoral and are carried out in semi-arid, high-altitude regions, characterized by a diverse range of microclimates and ecosystems [14]. At higher elevations, the breeding of guinea pigs (_Cavia porcellus_) is one of the primary agricultural activities [15; 16]. Guinea pigs are widely prevalent in rural Andean communities across Peru, Ecuador, Bolivia, and Colombia, having been domesticated between 2500 and 3600 years ago [17]. The production and utilization of guinea pigs hold significant importance for the area's sustainability, reflecting its traditional and ethnic/regional significance [14; 18]. Unfortunately, the potential of guinea pig manure for energy purposes remains largely untapped, and these resources are undervalued [11; 19]. However, exploring the bioenergy conversion of this specific waste is particularly compelling. One viable approach to address the energy needs of Andean communities is through the production of biogas from agricultural and livestock waste using anaerobic digestion (AD) technology. Additionally, wheat and quinoa are crops readily available in these regions. Several studies have explored the application of anaerobic digestion to guinea pig manure [15; 20]. These investigations highlight that anaerobic digestion (AD) holds significant potential for reducing farm waste while simultaneously offering an alternative means to fulfill local energy requirements by converting guinea pig manure into biogas [21]. The applications of biogas as a by-product of livestock activity can be focused on three different technologies: direct combustion in domestic kitchen burners or in gas boilers for heating; the use as biofuel in internal combustion engines; use as a biofuel in gas turbines. The application of biogas obtained from the fermentation of guinea pig waste in gas turbines has been little studied to obtain electricity in economically disadvantaged Andean areas. Therefore, this research is of great importance, since it explores a field that is necessary to analyze. The objective of this work was to evaluate this process through a computerized mathematical model to predict the behavior of this resource in gas turbines. This study uses the results of the evaluation of the productivity of co-digestion systems of guinea pigs, with wheat and quinoa previously tested by [PERSON] et al. [22].
