This investment was made when British International Investment was named CDC Group.

Our investment

Description of the investment.

Our investment in the company will fund approximately 295 megawatts of greenfield renewable energy generation capacity across India, Sri Lanka, Vietnam, Bangladesh, and Indonesia. This new capacity will increase the supply of renewable power for businesses, estimated to avoid 326,000 tonnes of carbon dioxide emissions each year. Our investment will help accelerate the uptake of renewable energy and help catalyse the sector’s growth in the region.

Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.



Increase the share of renewable generation in the energy mix to avoid greenhouse gas emissions (SDG 7.2 and 13.a).


  • Direct: Through funding the development of approximately 295 megawatts of greenfield renewable energy generation capacity in India, Sri Lanka, Vietnam, Bangladesh, and Indonesia to displace on-grid electricity consumption from primarily fossil fuel thermal generation sources.


Stakeholder Geography Characteristics



How much?

Scale Depth/Duration

Our investment is estimated to avoid over 326,000 tonnes of carbon dioxide emissions each year - 80 per cent in India, 15 per cent in Sri Lanka and 5 per cent across Vietnam, Indonesia and Bangladesh.


  • Financial additionality: Capital is not offered in the market in sufficient quantity and on suitable terms to meet the scale of India’s renewables targets. Mezzanine financing for commercial and industrial solar in other target markets is unavailable in sufficient quantity given the sector’s nascency.
  • Market: The commercial and industrial solar business model remains relatively nascent in some South Asian markets, and therefore executing projects in Sri Lanka and Bangladesh may contribute to catalysing the market in the medium to long term through a demonstration effect.

Grid score

Grid Score

To help us direct our investments, we previously used a tool called the Development Impact Grid. It scored investments out of four, based on two factors: the difficulty of investing in a country and the propensity of the sector to generate employment. This tool was used for investments until the end of 2021. Since 2022 it has been replaced by the Impact Score.



External Risk
  • Market: Relates to the risk of regulatory and/or policy adverse changes which could affect the viability of pre-construction distributed solar projects and therefore prevent impact from occurring. However, projects are likely to remain commercially viable even in the event of moderate changes.
Execution Risk
  • Relates to the risk of delay in completion of projects, for example, due to land acquisition or approval requirements. We consider this low risk because Fourth Partner has demonstrated execution capabilities in India.
Unexpected Impact Risk
  • Risk of negative impact on Indian distribution companies’ financial sustainability due to reduced revenues from C&I customers. We consider this low because C&I solar currently represents less than 1 per cent of total power generation in the market.

Environmental and social information

  • Environmental and social summary

    A high-level description of the environmental and social aspects of the investment. This may include a summary of key environmental and social risks identified during environmental and social due diligence (ESDD); key elements of an environmental and social action plan (ESAP); or ways in which we plan to support the investee improve environmental and social standards, such as through their environmental and social management system (ESMS); as well as any other priority areas agreed with the investee.

  • Environmental and social risk

    A risk category rating, which indicates the level of environmental and social risk associated with an investment. For an explanation of the categorisations used, see here. We consistently provide an environmental and social risk category for all investments screened from 2023 onwards.

Environmental and social summary

We continue working on the ESAP and areas of focus that were identified at the time of the main investment via regular engagement with the environmental and social manager.

    The geographical region where the country is located. We currently invest in Africa, South Asia, South East Asia and the Caribbean. In 2023, BII’s investment mandate was extended allowing it to invest in regional funds linked to Ukraine, with the majority of activity expected to begin post-war. Investments outside these regions were made prior to 2012 under previous investment mandates.

    South Asia

    We prioritise those sectors that facilitate development and need our capital the most. Our priority sectors contribute towards many of the Sustainable Development Goals. They range from investing in the power infrastructure that will provide people with better access to electricity, to investing in financial institutions that direct capital to the individuals and businesses that need it the most.


    We provide capital in the following ways: directly – through direct equity, direct debt, guarantees and other non-intermediated financial instruments; and indirectly – principally through investment funds.

    For direct investments and fund investments, this is the date BII committed capital to the investments. This is typically the date on which legal agreements are signed by all parties.

    For the portfolio companies of our fund investments, this is the date (either the month or the quarter) on which the fund committed capital to the portfolio company.

    For direct equity investments, this is the date at which British International Investment exited the investment.

    For debt investments, this is the date at which the final debt repayment was made.

    For funds, this is the date at which the fund was terminated.

    For underlying fund investments, this is the date at which the fund manager exited the investment.

    The total amount committed, per financial instrument, per investment, on the date BII becomes subject to a binding legal obligation to provide funding or assume a contingent liability. This information is provided in US dollars.
