Power sector Increases

Power sector Increases in grid spending were registered in the United States, Europe & India Investment in electricity grids dipped by 1% in 2018; China and the United States were nearly half of spending. Global spending on transmission grids, around 30% of network investment, has risen steadily during the last five years, supported by the connection of more generation, the system integration of variable renewables, and large-scale interconnection projects, though in some areas, constraints associated with permitting planning and project development remain investment challenges. Grid investment in the United States increased by 8%, with around 60% of spending in the distribution grid. Regulators continue to emphasise grid resilience and reliability. The potential downsides of underspending were in the spotlight in California with wildfires related to a lack of maintenance and replacement of distribution assets at the end of their lifetime. the European Network of Transmission System Operators identified USD 10 billion of annual transmission spending needs through 2030, implying a notable boost from current spending levels. India’s grid spending grew to over USD 20 billion, led by transmission, while distribution moderated. The Central Electricity Authority recently identified needs for USD 40 billion of transmission spending in the next three years, 60% higher than current levels. Investment in digital grid technologies rose by almost 10% to USD 35 billion. Most of this was in smart meters and grid automation equipment, but spending on EV charging stations rose by 60% to over USD 3 billion, with reports of utilities, automotive companies and oil companies moving to invest more in the space. Spending on traditional equipment remained the largest part of investment at nearly 45%. Spending in the Europe Union rose by 8%, largely due to investment in transmission.
