How can Sri Lanka meet its energy needs?

This research demonstrated how, through a supply of renewables and the use of energy storage, the hourly energy demands of Sri Lanka's power, heat, transport, and desalination sectors can be met in the BPS. Solar PV, including prosumer solar PV, provided up to 86% of the annual energy demand of the country by 2050.

Can Sri Lanka reinvent its energy system?

As global energy systems shift hastily away from the disruptive use of fossil fuels, the current crisis in Sri Lanka presents an opportunity to reinvent the energy system to one that is based on abundant indigenous renewable energy (RE) resources and able to meet the country's growing energy demand [ 2, 12 ].

Does Sri Lanka have an energy transition pathway?

Sankey diagram of the energy system in Sri Lanka in 2020. Fig. 2. Overview of the steps taken to define and identify the least cost energy transition pathways for Sri Lanka up to 2050. In this research, three pathways projecting the development of Sri Lanka's energy sectors in Fig. 1 up to 2050 are analysed.

What are Sri Lanka's energy policies & strategies?

Sri Lanka's energy policies and strategies strongly focus on developing conventional and nonconventional renewable energy sources for generating power. Promoting domestic energy resources has become one of the main policy components in Sri Lanka.

How efficient is Sri Lanka's energy system?

In Fig. 3, the average efficiency of the complete energy system in 2020 is estimated to be just under 60%. These numbers highlight the inefficiency and high costs, while the ongoing energy crisis indicates the fragility of the existing energy system in Sri Lanka.

Can battery storage meet the final energy demand of Sri Lanka?

Battery storage plays a significant role from 2030 onwards while meeting 34% of the final electricity demand in 2050. Results indicate that the increasing total final energy demand of Sri Lanka can be met through renewables-based electricity and a diverse mix of technologies.
