Clean Energy: How Is India Faring?

304views

The rising annual average global temperature due to global warming is alarming. These changes affect virtually every country in the world, and India is no exception in witnessing extreme weather conditions. To illustrate this, the country faced floods in 2019 that took 1,800 lives across 14 Indian states and displaced 1.8 million people. Overall, the unusually intense monsoon season impacted 11.8 million people, with economic damage likely to be around US$10 billion.

Concerns over rising global temperature causing climate change

According to the latest climate update by the World Meteorological Organization (WMO), there is a 50% probability of the annual average global temperature temporarily exceeding the pre-industrial level by 1.5 °C in at least one of the next five years. As a result, there is a high chance of at least one year between 2022 and 2026 becoming the warmest on record, removing 2016 from the top ranking.

India has also been bearing the brunt of climate change with the average temperature rising by around 0.7°C between 1901 and 2018. The temperature in India is likely to further rise by 4.4°C and the intensity of heat waves might increase by 3-4 times by the end of the century. In the future, India is likely to face weather catastrophes such as more recurrent and extreme heat waves, intense rainfall, unpredictable monsoons, and cyclones, if clean energy transition measures are not taken.

Clean Energy – How is India Faring by EOS Intelligence

India to witness economic losses if initiatives are not taken

The rising population, industrialization, and pollution levels in India are causing emissions (greenhouse gases, carbon dioxide), depleting air quality, and impacting the environment adversely. Also, with coal being a major source of energy in India’s electricity generation, pollution levels are further rising. These factors intensify the need to take clean energy initiatives seriously. If India does not take timely actions to reduce reliance on fossil fuels, it may suffer a heavy loss of nearly US$35 trillion across various sectors by 2070. Industries such as services, manufacturing, retail, and tourism are likely to lose around US$24 trillion over the next 50 years if India neglects climate warnings.

Renewable energy generation in India seeing a boost

The Indian clean energy sector is the fourth most lucrative renewable energy market in the world. As of 2020, India ranked fifth in solar power, and fourth in the wind and renewable power installed capacity globally.

The installed renewable energy capacity in India was 152.36 GW as of January 2022, accounting for 38.56% of the overall installed power capacity. Energy generation from renewable sources increased by 14.3% y-o-y to 13.15 Billion Unit (BU) in January 2022. The Indian government set an ambitious target of achieving 500GW installed renewable energy capacity by 2030, with wind and solar as key energy sources to achieve the target.

The government has been taking several measures to boost the clean energy sector. In the Union Budget 2022-2023, the government allocated US$2.57 billion for Production Linked Incentive (PLI) scheme to boost manufacturing of high-efficiency solar modules. The scheme provides incentives to companies to increase domestic production of solar modules in order to reduce dependence on imports.

Furthermore, the Indian government has undertaken several initiatives to foster the adoption of clean energy practices, one of them being the Green Energy Corridor Project, which aims at channelizing electricity produced from clean energy sources, such as solar and wind, with conventional power stations in the grid. Another project, the National Wind-Solar Hybrid Policy, was rolled out in 2018 by the Ministry of New and Renewable Energy (MNRE) as an initiative to promote a large grid-connected wind-solar PV hybrid system for efficient utilization of the transmission infrastructure and land.

Big-scale projects in development

To meet the growing energy needs of the country, the Indian government is taking measures to look at alternative sources of energy. At the 2021 United Nations Climate Change Conference, India announced its ambitious target of meeting 50% of its energy needs from renewable energy by 2030. In the near term, India aims to achieve 175GW renewable energy installation by the end of 2022.

Besides rolling out various policies and reforms, India has been taking several other measures as well to facilitate the growth of the renewable sector and to meet the energy targets. One such measure is the series of agreements signed by India and Germany in May 2022, which would see India receiving up to US$10.5 billion in assistance through 2030 to boost the use of clean energy. Furthermore, 61 solar parks have been approved by MNRE, with a total capacity of 40GW. Most of these solar parks are under construction.

Apart from the government, also the key industry players see potential in the clean energy market and have ambitious plans to ramp up renewable energy capacity as well as their investments in the sector.

Indian public sector companies including IOC, BPCL, and private sector conglomerates such as Reliance Industries, Tata Power, and the Adani Group have already announced billions of dollars’ worth of investments in renewable energy projects. BPCL is planning to invest up to US$3.36 billion in building a diversified renewables portfolio including solar, wind, small hydro, and biomass. Adani Green Energy is planning to invest US$20 billion to achieve 45GW of renewable energy capacity by 2030. RWE (German multinational energy company) and Tata Power are likely to collaborate to develop offshore wind projects in India. They are planning to install 30GW of wind energy projects by 2030.

Current and future challenges

Despite the measures taken by various renewable industry stakeholders, India still faces several pressing challenges that it needs to overcome.

The solar energy segment accounts for a majority share (60%) of India’s commitment of 500GW by 2030. With the ongoing momentum, India needs to install 25GW of solar capacity each year. In the first half of 2021, India could only add 6GW of renewable energy capacity, indicating a slowdown in the rate of energy addition. Besides the supply chain disruptions caused by the pandemic, another reason for the slowdown could be the high component prices.

India’s solar industry relies excessively on imports of solar panels, modules, and other parts. Before the pandemic, in 2019-2020, India imported US$2.5 billion worth of solar wafers, cells, modules, and inverters. These components have become 20-25% more expensive since the pandemic. To keep the clean energy market economically viable, the Indian government needs to increase the domestic production of solar equipment.

Another issue is the fact that power distribution companies in some states of India do not encourage solar net-metering because of the fear of losing business and becoming financially unstable. Thus, it is imperative for the government to introduce a uniform, consumer and investor-friendly policy regarding buying solar electricity equipment and accessories across all states in India.

Moreover, some solar ground-mounted projects have encountered difficulty because of the opposition from local communities and environmentalists for their negative impact on the local environment. According to energy pundits, rooftop solar installments are more eco-friendly and are able to create substantial employment opportunities. Consequently, increasing the current target for rooftop installations from 40% to 60% is considered to be a viable proposition for the near future.

Wind energy market also faces challenges due to lack of developed port infrastructure, higher costs of installing turbines in the sea, and delays in starting projects due to the pandemic. As a result, India’s first offshore wind energy project in Gujarat is yet to take off after four years of tender announcements by the government to invite companies to set up the project.

Some of the other challenges of wind power generation in India are additional costs including investments needed in transmission assets to evacuate additional power, issues related to ownership of wind plants by multiple owners, low Power Purchase Agreement (PPA) bound tariffs on existing assets, as well as lack of incentives to start new wind power projects.

EOS Perspective

As a large developing economy, India’s clean energy targets and ambitions are not just transformational for the country but the entire planet. The energy targets set by India are formidable, but the transition to clean energy is already happening; however, not without challenges.

With government support and aid, the Indian clean energy sector is likely to overcome some of those challenges. For instance, to reduce dependence on expensive imports, the government started taking measures to boost domestic production of solar modules through its Production Linked Incentive (PLI) scheme. Moreover, in 2017, the government increased taxes on solar panels and modules and hiked the basic customs duty on imports of solar and wind energy equipment to encourage domestic production of this equipment. In the budget for FY 2022, the government injected US$133 million into the Solar Energy Corporation of India and US$200 million into Indian Renewable Energy Development Agency. The capital will be used by these entities for running various central government-sponsored incentive programs to attract foreign and domestic companies to invest in this sector. In fact, foreign investors/companies already see potential in India’s clean energy sector, which led to FDI worth US$11.21 billion between April 2000 and December 2021.

India has immense clean energy potential, which has not been fully exploited yet. The shift to renewable energy presents a huge economic opportunity for India. The clean energy sector in the country has the potential to act as a catalyst for economic growth by creating significant job opportunities. According to a January 2022 report by the Natural Resource Defense Council (NRDC), India can generate roughly 3.4 million short and long-term jobs by installing 238GW of solar and 101GW of wind capacity to accomplish the 2030 goal.

In order for the clean energy sector to meet the energy targets and flourish in the future, it will continue to require government support and brisk actions to overcome the challenges.

Small Hydropower: Sub-Saharan Africa’s Answer to Energy Crisis?

509views

The Sub-Saharan Africa (SSA) region is believed to have bountiful energy resources, sufficient to meet the region’s energy requirements, however most of these resources are largely underdeveloped due to limited infrastructural and financial means. This has led to majority of the countries in the region to have restricted access to electricity, despite the presence of huge waterways, which could boost the hydropower sector’s growth, particularly the small hydropower (SHP) projects – plants with generation capacity between 1 and 20 MW. In recent years, SSA region’s focus has slowly shifted to SHP projects instead of depending on large-scale hydro plants, which are relatively expensive to construct and require longer time to build. However, question remains whether SHP has enough potential to improve electricity supply and reduce power outages across the SSA region.

African continent has approximately 12% of the global hydropower potential, most of which is centered in the Sub-Saharan region due to the presence of vast water bodies. Despite the underlying potential, the region faces massive electricity shortage partially due to under exploitation of hydropower.

Over the years, the SSA region has focused on the development of large-scale hydropower projects to increase its electricity generation capacity. However, recently, the emphasis has shifted to SHP because they are economically viable with almost negligible environmental effect and a short gestation period. Additionally, several small African economies utilize less than 500 MW of electricity annually, which negates the requirement to build a large dam, making SHP a viable option. Further, with comparatively lower overheads and maintenance costs, SHP could play a vital role in solving electrification problem in rural areas.

By 2024, the African SHP capacity is likely to reach 49,706.1 MW, growing at a CAGR of 19.2% since 2016, driven by the tremendous growth opportunities that the region offers. SHP projects are likely to proliferate in the region, owing to low capital investment requirement for installation, which makes SHP a more viable and affordable option than large-scale projects. SHP market still remains quite unexplored due to limited technological and infrastructural capabilities, and lack of sufficient promotion of SHP in national planning schemes.

Nevertheless, in the last couple of years, investments in the region’s SHP sector have increased, with various internationally-funded projects likely to commence installations. Geographically, countries such as Zambia, Uganda, and DRC (Democratic Republic of the Congo) are most suitable for SHP generation, due to the abundant presence of river basins and water resources. These countries depend predominately on hydropower for their energy requirements.

Hydropower is the primary source of power supply in Zambia, with a 99.7% dependency on hydropower to meet electricity needs. However, the country faces massive power outages due to fluctuating water levels, owing to persistent issue of scanty rainfall or droughts in the country, causing turbines to stop functioning to generate electricity. In 2015, the country witnessed a massive drought, which led to a huge decline in electricity generation. Nonetheless, since then, the country’s water level has improved, due to better rainfall pattern, resulting in higher level of power generation (as compared with 2015) through hydropower. The government has been making efforts to develop SHP stations to improve electricity supply – some of the SHP stations in the country include Lunzua, Mulungushi, Chishimba, and Shiwangandu hydropower stations.

Uganda’s power requirement is quite high due to extensive use of electricity in the industrial sector. The supply is always lower than the demand and the country faces frequent load shedding issue. Hydropower, accounting for 80% share in electricity generation, is the main source of power production in Uganda with a number of SHP plants in operation. Uganda’s government supports the hydropower market and has been making consistent efforts to promote SHP projects. For instance, in order to attract investors, the government provides incentives such as VAT exemption on hydropower projects.

DRC has the highest hydroelectricity potential in SSA due to the presence of particularly abundant water resources. Hydropower accounts for a share of 99% in DRC’s power generation. As of 2014, DRC’s total installed electricity generation capacity stood at 2,500 MW against its potential of 100,000 MW. In long term, DRC aims to become a key hydropower exporter in the region.

The SHP market across Zambia, DRC, and Uganda is still developing, with several potential SHP sites that could be harnessed to improve electricity supply. Each country faces its individual set of challenges in terms of SHP development, however, the hindrances seem trivial against the mammoth benefits that the countries could reap through SHP development.

Hydropower in Sub-saharan Africa

EOS Perspective

Hydropower holds a key position in SSA’s energy generation mix and SHP projects have particularly witnessed steady growth in the recent years. However, whether SHP has the potential to alleviate the power crisis in SSA is still debatable.

Is high reliance on hydropower a reasonable approach to overcome energy crisis?

While hydropower plays a dominant role in energizing the SSA region, continued energy crisis across various countries reflects the dangers of over-dependence on one form of energy for power generation. The chronic power shortages, load shedding, and low levels of electricity penetration are a clear indication that the SSA countries are unable to keep pace with electricity demands by heavily relying on a single power source.

Pinning hopes solely on hydropower to alleviate the energy crisis has spelled catastrophe for certain key industries, heavily reliant on electricity for functioning, that are suffering due to the electricity shortage. For instance, in 2014, DRC’s mining sector was adversely hit by the electricity supply shortage and development of new mines had to be frozen. The limited electricity supply situation has not yet improved, as DRC announced plans (in 2017) to import electricity from South Africa to support the struggling mining sector.

A solution to the electricity crisis could be to avoid heavily investing in one source for energy generation as well as to focus on tackling the fundamental vulnerabilities of power sector. In the long term, addressing the energy crisis would demand better management of water resources, continuously growing capacity of existing power plants along with a well-planned diversification of energy generation.

Is SHP a holistic solution to SSA’s energy crisis?

While focusing only on hydropower as a solution to the entire energy crisis situation across SSA countries might not be the best approach, developing SHP for rural electrification could be ideal to eradicate energy poverty across rural communities. SHP alone cannot consistently satisfy the energy demands of SSA countries such as Zambia, Uganda or DRC, but it can surely become the best possible solution to electrify rural areas, as people residing in these communities typically live closer to a river than to a grid.

Rural communities are characterized by much lower electricity access rates as compared with urban areas because people residing in villages typically cannot afford grid connections and in most cases the electricity supply through national grid does not reach the remote areas. SHP could play a major role in off-grid electricity supply that can be used for domestic application in rural households.

Besides the requirement to develop SHP particularly for rural communities, it is also essential for various SSA countries to adopt a cost-reflective tariff, which would ease pressure on public finances and attract more private investments.

Further, focusing only on increasing electricity supply is not a comprehensive solution to the crisis, as certain SSA countries such as Uganda suffer due to high tariff rates, which also need to be monitored. Uganda has one of the world’s highest electricity tariff rates and consumption is partially affected by it due to low affordability. The high commercial and industrial tariffs adversely impact some major industries such as agro processing (agriculture is a core sector of Uganda’s economy). A lower tariff rate could help to boost production across industrial sectors (including agriculture) and improve affordability among households.

Nonetheless, development of SHP projects would certainly help to move closer to eradicating the energy crisis in SSA region but only to a certain extent. It is imperative to take other measures as well to completely tackle the issues of supply shortage and load shedding. Development of SHP projects across the SSA region is challenging, however, navigating through these obstacles would be well worth the efforts, particularly in countries such as Zambia, DRC, and Uganda, where SHP could play a major role in rural electrification.
