Sri Lanka eversure energy systems

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 ].

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.

What is the cheapest energy system in Sri Lanka?

Solar PV accounts for 84% of the total PED, indicating that the core of the cheapest energy system for Sri Lanka is driven by a Power-to-X economy, where majority of the energy demand can be met by direct electrification, enabled by low-cost solar PV electricity within the island [ 51 ].

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.

What is the final energy demand of the Sri Lankan energy system?

The final energy demand of the Sri Lankan energy system, indicated as fuel, heat and electricity are given in Fig. 5 (a). The higher electrification across all the energy sectors in the BPS results in a higher electricity demand for the final energy system, with 70% of the total FED.
