IRENA Sets 1,200GW Annual Renewable Target Through 2030 as Grid Investment Gap Widens
The agency's new capacity figures show 2025's record 693GW build still fell nearly half short of what the next five years require.
Global renewable capacity additions need to nearly double from last year's record pace, IRENA said on Tuesday (2026-09-22), warning that an average of 1,200 gigawatts of new capacity must be installed annually between 2026 and 2030 to hit the 11.2 terawatt target set under the UAE Consensus. Total installed renewable capacity reached 5.15 TW at the end of 2025, with last year alone delivering 693 GW — itself a record, but still only 58% of what IRENA says is now the annual minimum.7
The gap between current trajectory and stated target is not marginal. Closing it requires grid investment of close to $1 trillion per year over the same period, IRENA said, with cumulative grid and flexibility spending estimated at $5.5 trillion through 2030. The IEA has put the grid investment requirement in starker operational terms: annual outlays need to rise roughly 50% from a baseline of $400 billion, according to the agency.7,4,2
Variable renewables — solar and wind — are projected to overtake total fossil fuel capacity and reach approximately 62% of overall installed power capacity by 2030, up from 35% in 2025. That shift is fast on paper. In practice it depends on grid build-out keeping pace with generation additions, a sequencing problem that has dogged past transition estimates. Francesco La Camera, IRENA's Director-General, called grid construction "one of the greatest infrastructure transformations in modern history," requiring a fundamental shift in investment priorities.7,4
Battery storage costs support the supply-side case. Costs fell 30% between 2024 and 2025 and have dropped 95% since 2010, according to IRENA data, reducing one of the main economic objections to high-variable-renewable grids. Over 90% of new renewables worldwide now produce electricity at a lower cost than the cheapest new fossil fuel alternative, IRENA added.7,4
On the demand side, electricity's share of global final energy use is projected to rise from around 23% to over 50% by 2050, according to Asian Power analysis. The IEA puts near-term demand growth at a 3.6% average annual rate between 2026 and 2030, driven by industry, electric vehicles, air conditioning and data centres. AI and data centres alone could account for as much as 4% of global electricity use by 2030, the IEA projected.3,2,1
Investment momentum has shifted in renewables' favour. Renewable energy is projected to attract $2.2 trillion in investment this year — more than double fossil fuel spending — and accounts for over 40% of the IEA's estimated $3.3 trillion global energy sector total. Solar leads with an expected $450 billion. For context, investment in fossil fuels had previously run 30% greater than electricity generation, grids and storage combined; the ratio has now reversed.1
But efficiency gains are lagging. IRENA's report published Tuesday (2026-09-22) showed energy intensity improved by around 2% in 2025, well below the 4% improvement rate needed to meet the UAE Consensus energy savings goal. That shortfall compounds the capacity gap: slower efficiency gains mean more raw generation capacity is required to deliver the same emissions reduction.7
The COP31 agenda adds a further benchmark. A roadmap under discussion would raise global electrification to 35% of total final electricity consumption by 2035, consistent with a 1.5°C pathway under IRENA's modelling. The IEA's net zero pathway estimates global CO2 emissions from energy falling 64% between 2022 and 2035, with accelerated electrification the primary mechanism.7,4
Financing constraints remain the sharpest obstacle outside the major economies. Developing countries face specific challenges limiting deployment pace, as Gulf News reported in January (2026-01-04), while coal continues to hold a dominant generation role across parts of Asia. The IEA has noted that solar generation is projected to jump roughly 30% this year with wind up around 10% — progress, but from a base far behind coal's installed capacity.5,6
Whether multilateral financing institutions commit to the volume of concessional capital needed to extend the grid investment ramp into emerging markets remains the most concrete near-term test of these projections. Without that commitment, the 1,200 GW annual target effectively relies on a handful of large economies to carry disproportionate weight.4,7
