This case study was developed using data from secondary sources. The data was collected from the organization’s website, annual reports, press releases, published reports and documents available on the internet.

According to the International Energy Agency’s (IEA) World Energy Outlook (WEO), 775 million people worldwide would not have access to electricity even by 2022, with the majority of them living in sub-Saharan Africa (SSA) (Cozzi et al., 2022). In SSA, energy poverty had been a serious issue over the years. According to the IEA, 600 million people lacked access to electricity in 2019, while 900 million people cooked with traditional fuels (Cozzi et al., 2022). A World Bank report from 2018 said many SSA countries had energy access levels of less than 25% (Cozzi et al., 2022). Energy poverty in SSA hampered sustainable development and economic growth.

Despite significant efforts to address this poverty, Africa remained the continent with the lowest energy density in the world. Although solar and other energy-saving products were appealing, their adoption rates were modest, and their distribution strategies were not particularly effective. The lack of electricity exacerbated a number of socioeconomic problems, as it increased the demand for and use of wood fuel, which caused serious health problems and environmental harm.

While working in Uganda, Katherine Lucey (Lucey) saw that having no electricity had negatively affected women’s health in particular because it was women who were responsible for taking care of the home. These effects were both direct and indirect. The women’s reliance on potentially harmful fuels for cooking, such as firewood and charcoal, resulted in their suffering from respiratory and eye problems, in addition to other health issues. Furthermore, the distribution of energy-saving and renewable energy items was seen as the domain of men, and there was an inherent gender bias in energy decisions. Women were not encouraged to participate in energy decisions, despite the fact that they were the ones managing the home and would gain from doing so. In addition, because there was no light after dusk, people worked less efficiently. Lucey saw the economic and social difficulties that electricity poverty caused for women in rural Africa. She also witnessed how the lives of a few families and organizations changed after they started using solar products. This motivated her to start Solar Sister with the mission of achieving a sustainable, scalable impact model for expanding access to clean energy and creating economic opportunities for women.

Solar Sister collaborated with local women and women-centric organizations to leverage the existing network. Women were trained, provided all the necessary support and encouraged to become Solar Sister Entrepreneurs and sell solar products in their communities and earn a commission on each sale. To provide clean energy at their customers’ doorstep, the Solar Sister Entrepreneurs received a “business in a bag” – a start-up kit containing inventory, training and marketing assistance.

Solar Sister’s business model empowered the women in SSA by providing them with an entrepreneurship opportunity and financial independence. Also, the use of solar products helped them shift from using hazardous conventional cooking fuels and lead a healthy life. The children in their households were able to study after sunset, and people in the community became more productive with access to clean energy.

The COVID-19 pandemic outbreak, however, had a serious impact on Solar Sister. It found it challenging to mentor and encourage new business owners due to restrictions on travel and on group gatherings. The Solar Sisters were unable to do business outside the house either. Their source of income, which they relied on to support their families, was therefore impacted. The COVID-19 outbreak also slowed down the progress achieved by the community over the years and made household energy purchasing power worse. Furthermore, the organization was also grappling with other issues like limited access to capital, lack of awareness and infrastructural challenges. Another challenge lay in monitoring and evaluating the organization’s impact on the last mile.

In the absence of standardized measurement tools and issues in determining the social impact of Solar Sister, it would be interesting to see what approach Lucey will take to measure the impact of Solar Sister on the society. What measurement tool/s will Lucey implement to gauge the social impact of Solar Sister?

The case discusses about how social entrepreneur Katerina Kimmorley founded Pollinate Energy with five of her friends to provide solar lights to the urban slum dwellers in Bengaluru, the capital city of Karnataka, a state in the Southern part of India. The company recruited people known as “Pollinators” for distributing their solar lights to the communities on installments making it affordable to them. To scale-up its sustainable energy initiatives and expand its global reach, Pollinate Energy merged with the US-based solar energy company Empower Generation in 2018 to form Pollinate Group. Since the company was making losses and was a nonprofit organization, the new CEO of Pollinate Group Sujatha Ramani and the senior management team had to tackle the challenge of scaling up the company while financially empowering women microentrepreneurs from marginalized communities.

Study Pollinate Energy’s business model and explore ways in which it can be made sustainable. Discuss the personality traits of Kimmorley which contributed to her success.

CSS 3: Entrepreneurship

Solar energy is on a rising trend internationally and in India. The government target of 100 GW solar capacity by 2022 from the present 12 GW is providing a major push for growth in India. However technological development and market competitiveness are pushing down the prices of solar power. The CEO of Amplus Solar has to deal with these challenges to ensure faster growth. He is analysing various options such as expanding the market to include customers who may not be as credit worthy, expanding to foreign geographies, diversification into providing energy efficiency and other services, and entering other markets such as Renewable Energy Certificates, carbon trading, etc.

This case describes the growth of ReNew Power during its first decade of operation. Sumant Sinha, a first-generation entrepreneur and former banker, founded the company, which grew from a modest generator-cum-developer of wind energy-based electricity to one of India's largest companies in the renewable energy sector. With the entry of large, well-funded players such as Tata Power and Adani Green into the Indian renewable sector by the end of 2020, Sinha had to make a strategic decision: should ReNew continue to organically scale up its presence in an increasingly competitive yet expanding Indian renewable energy sector, should it diversify geographically, or should it pursue emerging opportunities for vertical or horizontal integration within the sector? The case provides an opportunity to discuss how alternative business models and competitive scenarios may facilitate or inhibit the growth of a player in the renewable energy sector.

The learning outcomes of this study are to identify and discuss ways in which energy consumption in a residential educational institute can be reduced by improving demand-side energy management for sustainable development; summarise the challenges that an institute faces in transitioning to a more environmentally friendly mode of operations concerning energy management; illustrate the difference between operating expense and capital expenditure methods used for solar rooftop projects from the perspective of Goa Institute of Management (GIM); and analyse different project proposals for solar rooftop power generation energy using capital budgeting techniques.

Dr Ajit Parulekar, director at GIM, was evaluating the steps taken over the past few years for sustainable energy management to understand their impact and consider ways in which to take the environmental sustainability agenda forward. One of the projects that he was considering was the rooftop solar power plant. GIM had received proposals from several different vendors and evaluated three proposals out of these. He needed to decide on the capacity of the rooftop solar power generation and the type of contract that he should get into for the implementation of the project. This case study describes the differences and highlights the advantages and disadvantages of all the mentioned models with respect to GIM.

This case study is suitable for post-graduate level management students, as well as for undergraduate-level finance and management students.

This case depicts the challenges faced by Exalta in gaining a SCA because of the imitation of its products by competitors. Exalta, formed in 2008, was among the well-known innovative companies in the solar energy industry in India. In the first 12 years, the company focused primarily on unmet customer demand and developed innovative solar products to address those demands. Overall, over 300 products were launched in the initial years to address the new emerging customer demands. Solar AC, bikes and ventilators were among the popular ones. However, all of its product technology was copied by competitors. In 2021, troubled Exalta was incubated at IIT-Kanpur primarily for a single product, “Magic Inverter,” with substantial funding and IP protection. Despite attempts, Exalta could not capture a recognized market share. In this case, the company’s founder and CEO, Ashutosh Verma, is contemplating two options to gain an SCA: hold the existing and new products or fold the old ones and continue with one or two flagship products, i.e. Magic Inverter and Solar AC.

The portable solar cooker case is appropriate for upper division undergraduate and graduate students in entrepreneurship, international, strategy or sustainability courses.

xCRUZA, a small industrial design studio in Buenos Aires, Argentina, has experienced limited success and expansion since the company was founded in 2005. Focusing on eco design principles, xCRUZA has maintained an eclectic design mix pertaining to product development in children's toys, medicine, and cleaning products. Challenged by a struggling Argentine economy, a population not focused on environmental concerns, and a general lack of capital availability, the founders of xCRUZA chose to design, develop, market and sell a portable solar cooker. The cooker was originally designed by two of the founders while studying engineering at university. While innovative and award winning in design, xCRUZA's solar cooker has proven to be a challenge to the founders' success both in getting their product to market and fulfilling the mission of the studio.

The learning objectives for the case include: to explore the challenges of an entrepreneurial start-up dedicated to eco design and sustainability principles, to examine market opportunities and consider approaches to selling in dissimilar markets, generate a discussion on strategies that xCRUZA has and can employ, to analyze the mission and direction of xCRUZA. Are they on the right track?

Fewer than two percent of Guinea Bissau's rural households had access to electricity from the grid. Efforts by the state monopoly to improve that figure by expanding the grid have had little effect, in part because the rural population was sparse. Central Electronics Limited, a public sector based company in India, was assigned to develop economic solar systems as a safe and eco-friendly substitute for the diesel gensets under IBSA (a trilateral, developmental initiative among India, Brazil, and South Africa) with the help of United Nations Development Program. The case provides an opportunity to examine the strategy of a small and poor nation to meet the needs of modern energy sources needed for improvement in health, education, transportation, and commercial development. The case focuses on Guinea Bissau's use of a trilateral partnership to achieve its rural electrification objectives despite several push backs.

Students will demonstrate ability to analyse, comprehend, and evaluate the essence of solar energy as an alternate for costly grid energy in the initial stage of development. It will also provide students to converse with the specific advantages of solar systems over conventional power generating systems and construct a novel solution that serves the needs of various stakeholders at the bottom of the income pyramid.
