Diesel Generator Market Dynamics

Driver: Growing demand for uninterrupted & reliable power supply.

Due to the undeniable importance of a consistent and uninterrupted power supply in fostering the prosperity of contemporary societies, the reliance on electricity has become increasingly apparent. In today's digital economy, which operates round the clock, electricity serves as a linchpin across various sectors, from sustaining critical medical equipment in hospitals to facilitating remote work and virtual meetings. The recent challenges precipitated by the Covid-19 pandemic have only reinforced the pivotal role electricity plays in our daily lives.

As outlined in the IEA World Energy Outlook, the proportion of electricity in final energy consumption has steadily climbed from 15% in 2000 to 20% today, with projections indicating a further increase to 24% by 2040 if current trends persist. In alignment with the objectives of the Paris Agreement, the Sustainable Development Scenario emphasizes the potential for enhanced electrification across diverse sectors, foreseeing electricity accounting for 31% of final energy consumption by 2040. This trajectory underscores the escalating demand for electricity as a cleaner and more sustainable energy option. Against this backdrop of mounting electricity demand, diesel generators emerge as pivotal components in ensuring reliability during power grid outages or disturbances. As industries, commercial entities, and residential communities endeavor to mitigate the repercussions of electricity disruptions and sustain operational continuity, the reliance on diesel generators is poised to grow. This evolving trend underscores the indispensable role diesel generators play in furnishing backup power solutions and addressing the evolving energy requisites of modern societies.

Restraint: Rapidly growing renewable energy technology.

The growth of renewable energy technologies has been propelled by various factors, including escalating concerns over supply disruptions and the volatility of fossil fuel prices. Globally, energy consumers are increasingly embracing on-site renewable energy systems and transitioning towards electrified technologies across diverse sectors. For instance, the buildings sector witnessed a significant surge in heat pump installations in 2022, marking a notable 10% increase over the previous year, with Europe experiencing a particularly remarkable 38% growth. Similarly, the attractiveness of rooftop solar installations surged amid the rise in fossil fuel prices. In energy-intensive industries, worries about energy expenses and security drove a notable 21% uptick in corporate power purchase agreements (PPAs) in 2022. Renewable-powered industrial parks gained traction for providing insulation against energy price fluctuations and supply interruptions. Moreover, the transport sector grappled with rising energy costs, resulting in doubled energy bills for many public transport operators in Europe, although those with existing PPAs experienced more stable costs. The electrification of road transport continued its upward trajectory, witnessing unprecedented investment in electric vehicles and associated charging infrastructure, particularly in Asia. Several Asian nations implemented bans on internal combustion engine vehicles, further stimulating demand for electric alternatives. In agriculture, there's a discernible shift towards self-sufficiency and additional income generation through the adoption of renewable energy solutions like agrivoltaics, geothermal, and bioenergy. Solar water pumps, prevalent in the Asia Pacific region, have significantly enhanced agricultural productivity. As renewable energy technologies continue their expansion, there could be a potential impact on the demand for diesel generators. The increasing affordability and appeal of renewable energy alternatives may lead to a downturn in diesel generator demand, particularly in sectors such as buildings, industry, transport, and agriculture, where renewable energy solutions offer cost savings, energy security, and environmental advantages.

Opportunities: urbanization and industrialization.

During a special meeting, the President of the United Nations Economic and Social Council (ECOSOC) underscored the critical role of infrastructure, industrialization, and innovation in global poverty eradication efforts. Emphasizing the importance of Sustainable Development Goal 9 (SDG 9) focusing on these aspects, ECOSOC President Frederick Shava emphasized the necessity of prioritizing these goals in national, regional, and global policymaking. Urbanization presents a significant opportunity for industrial and infrastructure development, with the projected doubling of the population in emerging market cities by 2030, leading to an addition of two billion people to urban areas. However, this rapid urbanization also brings challenges, including the requirement for resilient infrastructure and industrialization in rural areas. Diesel generators can play a crucial role in addressing the energy needs of rapidly expanding urban centers and industrial hubs. As cities grow and industries flourish, the demand for reliable and uninterrupted power supply rises. Diesel generators offer a dependable backup power solution, ensuring continuous electricity supply during grid outages or fluctuations.

According to estimates by the UN Economic Commission for Africa (UN-ECA), Africa needs approximately USD 93 billion over the next three years to upgrade its infrastructure. Diesel generators can contribute to closing the infrastructure gap by providing reliable power for industrial operations, urban infrastructure, and rural electrification initiatives. Furthermore, diesel generators can support sustainable industrialization by offering affordable and clean energy solutions. As the international community commits to supporting infrastructure development and sustainable industrialization, diesel generators emerge as a viable option to meet the increasing energy demands of urbanization and industrial expansion.

Challenges: Stringent government regulations

According to the Renewables 2023 Global Status Report, the year 2022 witnessed a global expansion of climate commitments, with 10 countries revising their Nationally Determined Contributions (NDCs) to align with emissions reduction targets under the Paris Agreement. However, out of the 193 countries that have signed agreements, only 25 have set goals for achieving net-zero emissions. Climate policies enacted by various nations are focused on decarbonizing energy usage across diverse sectors, albeit with progress varying by region. In 2022, approximately 80 new renewable energy policies were introduced worldwide, primarily in the form of fiscal or financial incentives. These policies were implemented across 49 countries, with the majority concentrated in Europe, Latin America, and Asia.

Within the buildings sector, policies supporting the adoption of renewables, such as rooftop solar and geothermal heat pumps, were in place in 52 countries, featuring both fiscal and regulatory incentives. In the industry sector, 19 countries implemented policies incentivizing or mandating the use of renewables, primarily through renewable energy mandates and fiscal incentives. Notably, the European Union's Carbon Border Adjustment Agreement (CBAM) introduced a carbon tax on imports to EU member countries, expected to accelerate global industrial sector decarbonization. In the transport sector, 61 countries had renewable energy mandates or enabling policies, predominantly focusing on biofuel blending mandates and setting targets or bans on internal combustion engine vehicles. Regarding agriculture, 14 countries established targets and policies for renewables, primarily for solar-powered irrigation and agrivoltaics. These climate policies and renewable energy targets adopted by various countries could have implications for the market. As countries prioritize the adoption of renewable energy and enact policies to decarbonize different sectors, there may be a decrease in demand for diesel generators, particularly in industries and sectors where renewable energy alternatives are encouraged or mandated. Additionally, the transition towards renewable energy sources may result in a shift away from fossil fuel-based power generation, which could impact the market for diesel generators.
