Design Structure of Battery Energy Storage System: The design structure of a Battery Energy Storage System can be conceptualized as a multi-layered framework that seamlessly integrates various components to facilitate energy flow, control, and conversion. Here's a breakdown of the design structure: 4. Application Scenarios and Design Requirements
Energy storage is used to facilitate the integration of renewable energy in buildings and to provide a variable load for the consumer. TESS is a reasonably commonly used for buildings and communities to when connected with the heating and cooling systems.
Besides, CAES is appropriate for larger scale of energy storage applications than FES. The CAES and PHES are suitable for centered energy storage due to their high energy storage capacity. The battery and hydrogen energy storage systems are perfect for distributed energy storage.

Similar to the country's total energy system, the power sector relies heavily on natural gas (AEtN, 2016). The electricity network in Bolivia is broken into two classifications: the National Interconnected System (SIN) and the Isolated Systems (SAs).
Residential heating demands in Bolivia are quite low, though they do notably increase throughout the transition as access to energy services increase, except for biomass for cooking, which is phased out by the end of the transition. Heating demands are projected to increase from 52 TWh in 2015 to 205 TWh in 2050. Fig. 12.
Simulations performed using the LUT Energy System Transition model comprising 108 technology components show that electricity demand in Bolivia would rise from the present 12 TWh to 230 TWh in 2050, and electricity would comprise 82% of primary energy demand.
This transition for Bolivia would be driven by solar PV based electricity and high electrification across all energy sectors.
Heating demand in Bolivia transitions from a system dominated by natural gas and biomass to a largely electrified heating sector. Because of the low cost of renewable electricity, electric based heating will drive the transition for Bolivia's heat sector. Fig. 13.
Using Bolivia's own excellent solar resources to generate synthetic fuels in BPS-1 and BPS-2 would result in energy independence and security. Due to the lack of GHG emission costs in BPS-3 fuel costs remain for the fossil fuels used in the heat and transport sectors. Fig. 23.
