Grid-Connected Solar Power Generation
SectorMost major industry classification systems use sources of revenue as their basis for classifying companies into specific sectors, subsectors and industries. In order to group like companies based on their sustainability-related risks and opportunities, SASB created the Sustainable Industry Classification System® (SICS®) and the classification of sectors, subsectors and industries in the SDG Investor Platform is based on SICS.

Business Model Description

Invest in or provide project financing for large-scale ground-mounted and floating Solar PV power generation to supply the generated capacity to the national grid for residential and industrial/commercial consumption.

Over 50 solar ground mounted on-grid plants and 40 private sector companies contributing to about 100 MW capacity (17). In case of Solar PV rooftop industry, about 450 project developers/service providers registered at SLSEA (18). Examples of companies active in the IOA space:

WindForce ventured into solar in 2016 with its domestic and overseas solar power projects in Ukraine, Uganda and Pakistan. In 2021 it had 10 (6- SL and 4 - overseas) ground mounted solar and 2 rooftop solar projects with a total capacity of 136.23 MW. All projects have been successful in generating electricity for national use (10).

Regen Renewables (Pvt.) Ltd was established in 2013. The company is the recipient of a Presidential Award in 2017 from the Ministry of Power & Energy and Sri Lanka Sustainable Energy Authority for the contribution to the "Battle for Solar Energy", National Programme for the promotion of rooftop solar PV (11).

Nikini Solar, in 2008, was the first company in Sri Lanka to enter into a net metering agreement for its Solar PV System at their head office with the Ceylon Electricity Board. It is a division of Nikini Automation Systems (Pvt.) Ltd., and is an all-in-one solar energy provider. The company provides grid connected solar PV systems for domestic, industrial and commercial establishments. (12)

Expected Impact

Solar-based electricity generation to serve household, commercial, industrial, e-mobility needs and increase the proportion of RE in the total energy mix

Indicative ReturnDescribes the rate of growth an investment is expected to generate within the IOA. The indicative return is identified for the IOA by establishing its Internal Rate of Return (IRR), Return of Investment (ROI) or Gross Profit Margin (GPM).
15% - 20% (in IRR)
Investment TimeframeDescribes the time period in which the IOA will pay-back the invested resources. The estimate is based on asset expected lifetime as the IOA will start generating accumulated positive cash-flows.
Medium Term (5–10 years)
Market SizeDescribes the value of potential addressable market of the IOA. The market size is identified for the IOA by establishing the value in USD, identifying the Compound Annual Growth Rate (CAGR) or providing a numeric unit critical to the IOA.
> USD 1 billion
Average Ticket Size (USD)Describes the USD amount for a typical investment required in the IOA.
> USD 10 million
Direct ImpactDescribes the primary SDG(s) the IOA addresses.
Affordable and Clean Energy (SDG 7) Responsible Consumption and Production (SDG 12)
Indirect ImpactDescribes the secondary SDG(s) the IOA addresses.
Climate Action (SDG 13) Industry, Innovation and Infrastructure (SDG 9) Sustainable Cities and Communities (SDG 11)
