“…Obviously, the intrinsic intermittent characteristic of RES requires a considerable amount of energy storage capacity. However, if properly managed, storage facilities can enhance the dependability of energy systems and decrease electricity costs [20].…”

The energy transition towards a scenario with 100% renewable energy sources (RES) for the energy system is starting to unfold its effects and is increasingly accepted. In such a scenario, a predominant role will be played by large photovoltaic and wind power plants. At the same time, the electrification of energy consumption is expected to develop further, with the ever-increasing diffusion of electric transport, heat pumps, and power-to-gas technologies. The not completely predictable nature of the RES is their well-known drawback, and it will require the use of energy storage technologies, in particular large-scale power-to-chemical conversion and chemical-to-power re-conversion, in view of the energy transition. Nonetheless, there is a lack in the literature regarding an analysis of the potential role of small–medium CCHP technologies in such a scenario. Therefore, the aim of this paper is to address what could be the role of the Combined Heat and Power (CHP) and/or Combined Cooling Heat and Power (CCHP) technologies fed by waste heat within the mentioned scenario. First, in this paper, a review of small–medium scale CHP technologies is performed, which may be fed by low temperature waste heat sources. Then, a review of the 100% RE scenario studied by researchers from the Lappeenranta University of Technology (through the so-called “LUT model”) is conducted to identify potential low temperature waste heat sources that could feed small–medium CHP technologies. Second, some possible interactions between those mentioned waste heat sources and the reviewed CHP technologies are presented through the crossing data collected from both sides. The results demonstrate that the most suitable waste heat sources for the selected CHP technologies are those related to gas turbines (heat recovery steam generator), steam turbines, and internal combustion engines. A preliminary economic analysis was also performed, which showed that the potential annual savings per unit of installed kW of the considered CHP technologies could reach EUR 255.00 and EUR 207.00 when related to power and heat production, respectively. Finally, the perspectives about the carbon footprint of the CHP/CCHP integration within the 100% renewable energy scenario were discussed.

“…The transition in these countries will be complicated due to additional flexibility and storage demand to compensate extra energy requirement in the winter time, when RE generation may be limited. Assembayeva et al [26] discuss the perspectives of RE integration in the power sector of Kazakhstan and the impact of storage in such a system. This study shows that an energy system with a high share of RE in the power supply is feasible, however an option of a 100% RE system is not tested.…”

“…Institutional barriers include the absence of a clear national program for renewable energy development, a lack of specific action plans and instruments, a lack of concrete competitive legislation and regulation relating to the newly developed renewable energy market (Karatayev and Clarke, 2014). Another group of scholars lead by Assembayeva et al (2017) found new ways of solving mentioned above problems through storage technologies of renewable energy integration in Kazakhstan. Model proposed by them determines the optimal way of implementation of energy storage technologies and renewable energy sources.…”

Renewable energy attracts wide attention of world due to high importance and relevance. The study is devoted to this topic and aims to identify critical Project Management (PM) (further PM) knowledge areas those affect efficiency of green energy project, and to reveal PM tools those increase an efficiency. The study investigates 253 high-tech projects from Kazakhstan and compares green energy projects with projects from other industries like Information technologies (further IT), nanotechnologies and communications. Authors use PM Planning Quality (PMPQ) (further PMPQ) model for measuring the efficiency of these projects and for identifying critical factors of efficiency. Results show that IT projects have highest level of efficiency (cost overrun -12,2%, schedule overrun -2,8%, project performance -8,8), when green energy projects show average level of efficiency (cost overrun -45,13%, schedule overrun -6,2%, project performance -7,5). Research findings link these results with use intensity of PM processes. Project efficiency evaluation has also revealed critical knowledge areas for green energy projects like project schedule management, communication management, risk and quality management. Thus, authors have suggested tools and techniques from revealed knowledge areas for improving efficiency of project.
