The renewable energy sector is experiencing unprecedented growth. Its global market size hovered at $1.21 trillion in 2023 and is projected to expand at a compound annual growth rate of 17.2% between now and 2030. This remarkable trajectory is driven by a confluence of factors, including increasing environmental concerns, stringent regulations to reduce greenhouse gas emissions, and a global push toward sustainable energy solutions.

In 2023, the world witnessed a staggering 50% increase in renewable energy capacity additions, reaching nearly 510 gigawatts. Solar photovoltaic (PV) energy led the surge, accounting for three-quarters of new installations worldwide. The growth extended across the globe, setting new records in energy deployment.

As the sector expands, efficient supply chains become critical. The ability to source materials, components, and equipment in a timely and cost-effective manner will play a critical role in meeting ambitious energy renewal targets. However, the industry faces significant challenges, with supply chain disruptions threatening to impede progress and inflate costs.

What are the key renewable energy supply chain challenges?

The renewable energy sector is currently grappling with a complex web of supply chain challenges that threaten to impede its rapid growth and ambitious goals. These hurdles are multifaceted, ranging from raw material scarcity to extended lead times and construction material shortages. As the industry strives to meet the increasing global demand for clean energy solutions, these supply chain issues have emerged as critical bottlenecks that require immediate attention and innovative solutions.

The interconnected nature of these challenges amplifies their impact on the entire renewable energy ecosystem. From project conception to completion, each stage of renewable energy development is affected by these supply chain constraints.

Raw Material Scarcity

Sustainable growth in the renewable energy sector heavily depends on a steady supply of critical raw materials, many of which face increasing scarcity. Lithium, cobalt, and graphite are among the most crucial elements experiencing shortages. They are essential components in various renewable technologies, particularly in energy storage systems and electric vehicle batteries.

Demand for these materials is projected to skyrocket by 2030, with some estimates suggesting a sevenfold increase for certain elements. This exponential growth in demand is primarily driven by the rapid expansion of the renewable energy sector and the electrification of transportation.

The scarcity of raw materials significantly impacts the renewable energy market. Price volatility has emerged as a major concern, with sudden spikes in material costs affecting project budgets and overall feasibility.

Additionally, supply chain constraints are creating uncertainty in the industry, potentially slowing the pace of renewable energy adoption and threatening to derail climate change mitigation efforts.

Extended Lead Times

Many of the challenges in procuring essential components cause extended lead times that disrupt project timelines. Critical elements such as batteries, inverters, and turbines—the backbone of renewable energy systems—now require ordering months or even years in advance of project completion.

Global supply chain disruptions extended the timeframe for advance orders, increased demand, and caused manufacturing bottlenecks. Some components that previously required an 8-week lead time now require up to 35 weeks or more for delivery.

These extended lead times profoundly affect project planning and execution. Developers must now factor in these delays when creating project timelines, often resulting in longer overall project durations. It forces companies to adapt their strategies, including earlier procurement processes, more flexible project schedules, and the exploration of alternative suppliers or technologies.

Construction Material Shortages

In addition to grappling with shortages of specialized components, the renewable energy industry also faces a scarcity of basic construction materials. Items such as cabling and semiconductors—crucial for the construction and operation of renewable energy facilities—are in short supply.

These shortages are having a significant impact on the construction phases of renewable energy projects. Delays in obtaining necessary materials can lead to project setbacks, increased costs, and potential contractual issues. In some cases, the lack of basic materials has forced developers to pause or reschedule construction activities, further complicating project timelines.

Companies are diversifying their supplier networks, stockpiling critical materials when possible, and exploring alternative materials or designs to mitigate these shortages.

What are the consequences of supply chain disruptions?

The renewable energy sector’s ambitious growth trajectory is facing significant headwinds due to persistent supply chain disruptions. These challenges, ranging from raw material scarcity to logistical bottlenecks, have far-reaching consequences that ripple through the entire industry.

As the sector grapples with these issues, three primary areas of concern have emerged: project delays, cost overruns, and increased pressure on profit margins. These interrelated consequences are impacting individual projects and threatening the overall pace of the global transition to clean energy.

Project Delays

One of the most immediate and visible consequences of supply chain disruptions in the renewable energy sector is the widespread delay of projects. These delays not only affect the projects themselves but also have broader implications for energy policy, climate goals, and investor confidence in the sector.

• Extended construction timelines. With critical components facing long lead times, construction schedules are stretched beyond initial projections. This dramatic increase in wait times is forcing project managers to revise timelines repeatedly, often pushing completion dates by months or even years.
• Postponed installations. Many projects slated for completion in early 2023 were pushed back because of supply chain challenges. The ripple effect caused by those delays continues to impact the industry’s ability to meet renewable energy targets and commitments.
• Cascading delays. The interconnected nature of renewable energy projects means that a delay in one area can have far-reaching effects. A shortage of inverters, for instance, can hold up the entire solar farm installation, even if all other components have arrived.

Cost Overruns

Supply chain disruptions are leading to significant cost overruns across the renewable energy industry. These cost overruns are not just isolated incidents but are becoming a systemic challenge for the industry, threatening the economic viability of many renewable energy projects.

• Rising material costs. The scarcity of raw materials and critical components had led to sharp price increases. Polysilicon—a key material in solar cell production—has seen dramatic price fluctuations, directly impacting the overall cost of solar projects.
• Increased financing costs. Project delays can cause extended financing periods, leading to higher interest payments. The recent rise in interest rates has further complicated matters because clean energy projects are more sensitive to interest rate increases due to their high upfront capital requirements.
• Renegotiation of contracts. The volatility in costs has forced many companies to renegotiate power purchase agreements. A significant drop in corporate purchases of clean energy occurred in the first half of 2023, with only 6GW contracted compared to nearly 17GW for all of 2022. This renegotiation process incurs additional costs and can lead to less favorable terms for project developers.

Pressure on Profit Margins

The combination of project delays and cost overruns is exerting significant pressure on profit margins across the renewable energy sector. These pressures on profit margins are not just short-term obstacles but represent a significant challenge to the industry’s long-term growth and sustainability.

As companies struggle to maintain profitability, there’s a risk of reduced innovation and slower adoption of new technologies, which are crucial for advancing the renewable energy sector.

• Squeezed profitability. As costs rise faster than anticipated, projects can see their profit margins erode. This is particularly challenging for projects with fixed-price contracts that were negotiated before the recent surge in costs.
• Investor hesitancy. The financial challenges faced by renewable energy companies are reflected in their stock performance. Clean energy stocks have seen downward pressure, making it more difficult for companies to raise capital for new projects.
• Project cancellations. In some extreme cases, the economic pressures had led to project cancellations. In the offshore wind sector, about half of the U.S. pipeline faced delays or cancellations in 2023 due to rising costs and supply chain challenges.
• Long-term industry impact. Persistent pressure on profit margins could lead to a slowdown in investment in the renewable energy sector, potentially jeopardizing long-term climate goals and the pace of the energy transition.
