Last Updated: January 05, 2026 | Format: PDF | Report ID: FBI110449 The global power generation market size was valued at USD 1,062.27 billion in 2024. The market is projected to grow from USD 1,185.11 billion in 2025 to USD 2,022.56 billion by 2032, exhibiting a CAGR of 7.94% during the forecast period.
Distribution Capital spending on the distribution system, responsible for delivering electricity to end users, was the main driver of electricity spending increases over the last two decades. Capital investment in distribution infrastructure increased by $31.4 billion, or 160%, from 2003 to 2023.
Annual spending by major utilities to produce and deliver electricity increased 12% from $287 billion in 2003 to $320 billion in 2023 as measured in real 2023 dollars, according to financial reports to the Federal Energy Regulatory Commission (FERC).
More recently, capital spending on electricity production increased by 23% ($4.7 billion) in 2023 compared with 2022. Most of this increase was driven by costs related to the construction of the Vogtle nuclear plant operated by Georgia Power. The fourth and final Vogtle unit entered commercial operation at the end of April 2024.
Most homeowners spend between $12,600 and $33,376 to install a complete residential solar system in 2026, with the national average at $19,873 before incentives. Your actual cost depends on your home's energy needs, roof characteristics, location and other factors, all of which we'll break down in this guide.
These costs are for a typical 7 kW residential system ($19,873 average). Monocrystalline or polycrystalline panels are the most common types of solar panels. Most residential installations use monocrystalline photovoltaics (PV) panels, which offer up to 24% efficiency and perform better in limited space and extreme temperatures.
Monocrystalline solar panels are the most popular choice for residential installation (nearly all residential solar panels installed in 2022 were monocrystalline) because they have the highest efficiency rates from 17% to 22%. The average cost for these panels is between $1 and $1.50 per watt, but prices may differ depending on location.
