Recently, the Albanian government has compiled national energy strategy with a special focus on promoting the use of renewable energy sources (RES) which identifies a target of 42% of the final energy consumption from RES by 2030. In this paper, analyses are conducted in order to investigate to which extent and way the absorption capacity of the power system from RES electricity can be improved. As an effective approach of implementing wind power, fostering the accommodation of renewable energy sources, especially on large-scale, a detailed techno-economic analysis of the 164 MW installed grid-connected wind farm, considered as a potential source, Korça district is analyzed. Conjoining two different types energy tools, RETScreen, a tool used on plant scale level and EnergyPLAN model applied for large energy system on national level including all energy sectors an optimization process is notably focused to attain 42% of the final energy consumption from RES by 2030, which was highly preformed in EnergyPLAN model. The results execute in EnergyPLAN identifies that the wind power capacity should be at least1850 MW and an installation cost not more than 1.1m€/ MW considering a bench mark price of electricity €76/MWh. The results of the study highlight the importance of high levels of RES integration which not only reduces greenhouse gases but will technically favor the creation of a flexible and sustainable energy system over time. Finally, the need for a sustainable and clear national energy model is inevitable, reshaping key points factors that hamper the integration on large-scale of wind power in Albania.

“…The software allows to analyse the optimization opportunities, including sensitivity analysis, depending on optimization variables and local weather data obtained from international statistical weather databases [16]. The program has also the ability to calculate energy balances on each possible configuration generated by the different components that form an investigated HES solution [17].…”

The paper investigates hybrid energy systems that could be applied in case of a swimming pool complex in order to reduce exploitation costs and increase renewable energy usage. The presented approach starts with the assessment of the chosen building at the level of energy consumption, and utility costs, along with two proposed system configurations: one proposed by the RE-COGNITION innovation project, and one proposed by the authors based on the market solutions. The mentioned cases represent two hybrid energy systems using conventional sources, renewable energy, and highly efficient cogeneration units. The two proposed system configurations are simulated using the HOMER Pro program which allows a wide analysis along with techno-economic indicators of the different scenarios. Results and comparisons are presented to highlight the feasibility of the two proposed cases.

“…There exist a number of papers published with the results gained by using the RETScreen. Vollaro et al have used in combination the TRNSYS and RETScreen for calculation model to optimize the design of low impact energy systems for buildings [15]; in their work, Ramli et al did the comparison of Renewable Energy Technologies Using Two Simulation Softwares: Homer and RETScreen [16]; Lalita P. et al have analysed the Energy Comfort Management in Energy Efficient Building using the RETScreen software with a case study [17].…”

An energy performance study of a building using the Montenegrin and European Standard on Energy Building Performance and the RETScreen software to compare the results from analysis for a one chosen hospital building is presented. In this study, the appropriate mathematical model of calculation is performed for the purpose of the analysis, using Excel software and algorithm which has been proposed by the above mentioned standard (the monthly method). The inspection of the current conditions of hospital building in Prizren, Kosovo is done and energy efficiency measures are proposed for improving the conditions of stay. All data are collected and gained through the inspection, and calculations are performed for existing and proposed condition of the building. The obtained results for both models are compared and show that most of the energy indicators have small differences in percentage among each other. There is a difference in carbon dioxide emission reduction between two models, due to the fact that calculations with the European standard resulted in the need of higher energy for cooling after the energy efficiency measures (14.75 megawatt hour), and considering that the source of energy for cooling is electricity, in terms of the Carbon dioxide equivalent emission, this means 21.21 tons Carbon dioxide equivalent, more to be emitted after the energy efficiency measures.
