Renewables Depend on $15.8 Trillion Grid Buildout Through 2050
BloombergNEF projects $15.8 trillion in grid investment from 2025 to 2050 under its base-case energy transition scenario, including a 29-million-kilometer grid extension. The spending is needed because solar and wind projects are often far from demand, and grid planning can take 5–15 years versus 1–5 years for renewable generation. The IEA also estimates annual grid investment must rise about 50% from a $400 billion baseline by 2030, while over 2,500 GW of projects sit in connection queues.

... No extra. Need maybe "EXPANDED:" then paragraphs. We can include blank line between paragraphs? It says two short paragraphs. We can have two paragraphs separated by blank line. Under 120 total. Good. Need ensure no source phrasing copied. Let's check EXPANDED. "base case" maybe source "base-case". "grid spending" source "grid investment". "29 million kilometers" source. "cables, towers, wires and substations" source exact list. That might be copying source phrasing? It says entirely original wording, never copying source phrasing. We should avoid exact list? But factual terms. Could rephrase: "cabling, pylons, conductors and substation equipment" but "substations" is term. Source says "cables, towers, wires and substations." We can say "transmission hardware such as cables, towers, wires and substations" still exact. Better: "physical assets including lines, support structures, conductors and substation equipment." That's original. But "substation" term. Fine. Need maybe "Data ce
