Analysts and Market Drivers in Focus
The US Energy Information Administration (EIA) has nearly halved its growth forecast for electricity consumption in Texas following the state's provisional halt on new data center projects, cutting the 2027 estimate from 14 percent to 6 percent. Solar remains the largest source of growth in the US power mix, up 21 percent in the first half of 2026. The EIA also reported 8.3 gigawatts of battery storage additions in the first half of 2026, bringing installed capacity to around 52 GW, with a further 54 GW planned by 2028, including 14 GW this year alone. In Kenya, wind and solar power at times already account for 34 percent of electricity generation, a trend state utility Kenya Power views as posing economic offtake risks under existing take-or-pay contracts. In the EU, renewable energy accounted for 49.8 percent of electricity feed-in in July 2026, up from 47.9 percent a year earlier, with solar power the main driver at a gain of 24.3 percent; solar feed-in has moved close to nuclear power output, reaching around 91 percent of nuclear generation levels. Turkey, meanwhile, is preparing to enter the offshore wind market, with a first tender for 1,000 MW planned for the first quarter of 2027 and expansion to 5 GW targeted by 2035. Data analytics and consulting firm GlobalData considers the target ambitious, forecasting closer to 1.3 GW by 2035.
