And the electric power sector is no exception. The sector was grappling with numerous challenges within its supply chain networks even before recent disruptions driven by the pandemic and the Russian invasion of Ukraine. 1 These disruptionsranging from logistics bottlenecks to shortages of raw materials and components and labor shortageshave resulted in rising costs and a scarcity of essential electric supplies. 2 They have also widened the gap between demand and supplies of electrical equipment and components, slowing the clean energy transition. As a result, many electric power and renewable energy companies are revisiting supply chain strategies and rebooting their approach to supply chain risk managementand their boards increasingly expect it. Some are integrating supply chain management deeper into business planning and involving supply chain managers in the capital planning process. They are working to develop more secure and sustainable supply chains, while managing third-party risk to ensure resilience in the face of future disruptions. To better understand the types of supply chain disruptors, their impact on the sector’s operations, and the strategies used to overcome these disruptions, Deloitte surveyed more than 50 electric power and renewable sector executives in the United States. The findings were supplemented by interviews with executives and leaders in utilities and other electric power providers. Using these insights, this report takes an in-depth view of how the electric power sector can improve its supply chain security, sustainability, and resilience. 2 Multiple disruptors impact the electric power supply chain A COMBINATION OF DISRUPTORS is driving supply chain gridlock and impacting end- to-end operations in the electric power sector. Prepandemic supply chain vulnerability, due largely to the geographic concentration of component manufacturing and critical minerals mining, has been compounded by the effects of the pandemic and the Russian invasion of Ukraine. We have divided these disruptors into five categoriesenvironmental, geographic, operational, technological, and macroeconomic which impacted between 32 and 98 of our survey respondents’ supply chain operations figure 1. 3 Electric power supply chains Achieving security, sustainability, and resilience FIGURE 1 Respondents report operational and macroeconomic disruptions as the most signiﬁcant supply chain challenges Percentage of respondents who identiﬁed each disruptor as having signiﬁcant impact 98 Operational Manufactured component shortages, logistics constraints, divergent product standards and regulations Limited availability of raw materials and longer lead time for components Global shipping congestion, rising freight charges, and container shortages are aﬀecting project timelines Divergent product standards coupled with pent-up demand can hinder electrical equipment procurement 92 Macroeconomic Trade policies, labor shortages Trade tariﬀs and quotas can disrupt procurement of materials and components from foreign suppliers, and domestic manufacturers may lack production capabilities to ﬁll gaps Labor constraints at ports and shortages of skilled laborers are also contributing to the supply imbalance 44 Technology Risk of cyberattacks, chip shortages Fragmented digital supply chains for electric power companies are contributing to supplier-driven cyber risks The global shortage of high-end semiconductors concerns electric power companies, as components such as solar panels and wind turbines require chipsets to control and manage 42 Geographic Major commodity shortages, price ﬂuctuations Clean-energy transition is shifting key raw materials from fuel to minerals, making supply chains highly dependent on potentially insecure foreign sources Global materials sourcing often limited to a small number of countries can constrain supplies of power equipment and materials 32 Environmental Tougher environmental regulations, climate-related natural disasters Increasing severity and frequency of extreme weather events risks damaging utility infrastructure Stringent environmental policies for domestic mining have led to US dependence on foreign sources Source Deloitte Electric Power Sector Supply Chain Survey. 4 r··\ Nearly all of the respondents 98 consider operational challenges as major disruptors in their supply chains. In addition, almost all 92 also see macroeconomic factors, such as labor shortages and trade policy, as significant disruptors. Pandemic-driven labor shortages, on top of preexisting shortages resulting from a rapidly retiring workforce, are further exacerbating supply chain challenges. The impact of these disruptors on the electric power sector has been wide-rangingfrom increased costs to project delays figure 2. They’re not only impacting grid modernization efforts and clean energy deployment, but also causing service- related delays. Electric power companies are draining inventories as they continue to upgrade equipment, while replacements are often delayed. 3 FIGURE 2 Along with other supply chain disruptions, a US trade investigation into solar panel supplies from four Southeast Asian nations has also loomed over the industry, with the potential to further constrain supplies. To mitigate the dampening effect on the market, the Biden administration waived tariffs on panels from the four nations for two years and invoked the Defense Production Act to boost domestic solar panel manufacturing. a a Nichola Groom, “US to consider tariffs on solar panels made in Southeast Asia,” Reuters, March 29, 2022. And ripple effects are impacting the broader economy, sometimes slowing new home construction due to a lack of electrical equipment especially distribution transformers and smart meters 4 and delaying transportation electrification. 5 Electric power providers highlight multiple consequences of supply chain disruption Percentage of respondents who selected each consequence 86 Increased operational costs 64 Project delays 62 Loss of productivity 36 Loss of sales 28 Increased lead times 22 Customer impact Source Deloitte Electric Power Sector Supply Chain Survey. 5 Electric power supply chains Achieving security, sustainability, and resilience delivery lead time Cost Lead increase time According to our survey, respondents believe increased operational costs 86, project delays 64, and loss of productivity 62 are significantly impacting the industry. Among the industries most acutely affected by these supply chain constraints has been the solar industry, where a third of all utility-scale solar capacity scheduled in the United States for completion in Q4 2021 was delayed by at least a quarter. At least 13 of the planned capacity for completion in 2022 has either been delayed by a year or canceled. 6 This trend will likely continue over the next two years as some utilities have warned they may need to delay 3–4 GW of total solar installations until 2024 due to shortages of solar panels and other equipment. 7 A severe shortage of key commodities, materials, and labor can create an inflationary cost environment for companies, resulting in increased component costs. Transformer prices have doubled, while the average lead time for delivery has at least tripled from what it was two years earlier, reaching 52 weeks in some cases figure 3. 8 FIGURE 3 Disruptors have signiﬁcantly impacted components’ cost and Transformers 20–100 100–400 Wire and cables 20–60 60–300 Precast manholes 60 400–600 electric PVC conduits 400–500 900–1,400 Stainless steel 5–20 200–300 valves and ﬁttings Batteries 15–25 50–100 Solar PV 20–30 30–50 Note Cost increases and lead time are calculated from secondary research, examples, case studies, and utility project status reports, using information from the sources listed below.

And demand for renewables could increase even more rapidly with enactment of the Inflation Reduction Act and the incentives it provides. 12 But building clean energy technologies such as solar and wind generally requires more minerals, including rare earth elements, than traditional fossil-fuel technologies. 13 Our analysis shows that about 31 million tons of key minerals/materials are required to support solar and wind demand in the United States by 2050 figure 4. With high reliance on imports for most of these materialsand competing demand from other industries for the same mineralsthere’s an imminent mismatch between US climate goals and the availability of critical minerals essential to meet them. 7
