1993 NEC Section 300-7 (b) states that "Raceways shall be provided with expansion joints where necessary to compensate for the thermal expansion or contraction. As cables and trays expand or contract, they can cause stress on the structure, leading to potential damage or misalignment. Considering a 100m cable bus system under normal site conditions, an Aluminum housing would expand 18cm.

Appearing on the programme En Vérité on 3 May 2026, the minister unveiled a plan to add a further 1,250 megawatts to the grid by 2027, representing an increase of nearly two-thirds on the country's current capacity, estimated at around 1,902 MW. With a national electricity access rate of 84%, Senegal is making progress towards universal energy access, yet more than 30 % of rural communities remain disconnected from the grid. As part of the Just Energy Transition Partnership, Senegal has committed to bold reforms to increase renewable. They involve building 1,350 km of high-voltage and very-high-voltage overhead and underground t ansmission lines to connect several thousand homes. The Minister for Energy, Petroleum and Mines, Birame Souleye Diop, has announced an unprecedented acceleration of the national energy strategy.

These projects aim to increase transmission capacity, reduce bottlenecks, and improve electricity supply reliability, particularly in high-demand regions. The upgrades will also support Norway's electrification efforts and enable better integration of renewable energy. As the share of renewable and fluctuating generation increases, a strong Nordic grid will have a key role in balancing. The Norwegian Ministry of Energy recently introduced new regulations requiring mature projects to be prioritised in the grid capacity queue.

A concrete cold joint is where fresh concrete meets already hardened concrete after a delay. Expansion joints help control movement and prevent cracking by giving concrete room to expand and contract. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with the fresh mix. While most are deliberate and strengthen the structure, one, in particular, does not: the cold joint.
