Building supply chain readiness to support demand growth in high-voltage infrastructure

When demand ramps up, the ability to deliver reliably and on time with shorter lead times is a powerful competitive advantage. On the flip side, fall behind on material availability, supplier readiness, or visibility across the supply chain and you’re at risk of delayed revenue, losing out to competitors, and high expediting costs. With demand for power transmission infrastructure surging, a leading manufacturer of high-voltage electrical equipment was facing this exact challenge. 

Rising investment in grid infrastructure, clean energy, data centres, and asset replacement has increased demand for transmission and distribution equipment. For manufacturers in the sector, ensuring supply chains keep pace and managing extended lead times have become increasingly challenging.  

The manufacturer was making significant investments in expanding its production capacity of high-voltage equipment at one of its North American sites. However, material shortages and inconsistent supplier delivery were constraining output, and rising air freight costs pointed to a supply chain operating reactively. The manufacturer engaged Efficio to identify the structural causes of these limitations and help build the foundations for a sustainable ramp-up. 

The client-Efficio team conducted an end-to-end supply chain diagnostic across the value chain nodes including planning, purchasing, supply chain management, and suppliers.  

The diagnostic revealed that the main stumbling block was translating demand into stable, actionable supply chain plans. Internal planning processes, gaps in forecasting accuracy, inventory policies, and supplier coordination were creating instability throughout the supply chain. The assessment also found that engineering change governance and master data issues were contributing to delays. Although shortages were concentrated across a relatively small number of critical components, their impact on production flow was disproportionately large. 

Together, these issues were increasing operational complexity, creating avoidable delays, and making it harder to secure the right materials at the right time to support production ramp-up. 

Efficio worked alongside the manufacturer’s team to build durable supply chain capability rather than short-term fixes. Together, the team focused on four priority areas to stabilise supply, improve planning discipline, and support the site's production ramp-up. 

Together, the client-Efficio team helped the site transition from reactive shortage management to a forward-looking, integrated operating model with a clearer view of material requirements, stronger supplier alignment, and reliable planning.  

New forecasting and supplier development processes gave the site a stronger basis for managing future demand, and improved delivery performance controls helped teams identify risks earlier and stay closer to targets. This reduced reliance on reactive expediting and firefighting. 

As investment in high-voltage manufacturing continues, these changes position the business to respond more confidently to customer demand and strengthen resilience across its supply chain.
