Wind Milestones & Policy
- 1999
Texas Renewable Portfolio Standard created — 2,000 MW mandate, first in US southwest. Market-driven not mandate-driven from the start.
- 2005
CREZ (Competitive Renewable Energy Zones) plan launched — $7B in transmission investment to bring Panhandle/West TX wind to demand centers.
- 2009
Texas surpasses 10 GW wind, overtakes California as #1 wind state. CREZ transmission buildout accelerates.
- 2014
CREZ transmission fully operational. Unlocks 18+ GW of stranded West Texas wind capacity. Wind sets ERCOT generation records.
- 2021
Winter Storm Uri — wind turbines (and gas plants, coal plants) freeze. ERCOT grid within minutes of total collapse. 246 deaths. Prompted weatherization rules.
- 2022
Wind + solar provide 30%+ of ERCOT generation for first time. Texas surpasses 30 GW wind capacity.
- 2024
40 GW wind installed — 5× more than #2 state Iowa. Wind generated more energy than coal for the first time in ERCOT history.

Texas GHG Emissions by Sector (2022)
The Oil & Gas Methane Problem
Texas emits roughly 650–700 MT CO₂e/year across all sectors — more than most countries. The electricity sector (~185 MT) is visible and tracked; the oil & gas production sector (~200 MT) is notoriously under-measured.
Permian Basin methane leakage rates have been measured at 2.5–3.7% of production by satellite (GHGSat, Carbon Mapper), far above EPA estimates. At 3%, Permian methane venting erases the climate benefit of gas vs. coal over a 20-year horizon.
Texas has no state methane regulation equivalent to Colorado's Rule 7 or EPA OOOOa. Plugging ~140,000 orphaned wells (Texas Railroad Commission inventory) is a decade-scale remediation challenge.

Coal Retirement Timeline
- 2012
Luminant closes Monticello (1,880 MW) — first major ERCOT coal retirement, driven by low gas prices after Marcellus/Haynesville shale revolution.
- 2016–18
Fayette Power Project units, Big Brown Plant, Monticello Units 3 retire. ~4 GW coal capacity removed.
- 2021
Winter Storm Uri: coal plants freeze alongside gas and wind. Subsequent reliability reviews argue for keeping remaining coal as backup — slowing retirements.
- 2023
ERCOT coal generation falls below 13% for first time — wind + solar + storage finally outcompeting dispatchable coal on energy margins.
- 2026–30
~7 GW coal retirement scheduled (Luminant Martin Lake, Sandow, Parish units). Remaining capacity likely converted to gas peakers or demolished for solar + storage.
- 2035?
Market trajectory suggests near-zero coal. No legislative mandate exists — retirement is purely economic, driven by carbon-free LCOE now below coal operating costs in most hours.

SMR Pipeline — Texas is a National Leader
- 2023
Dow Chemical + X-energy announce 4 × Xe-100 high-temperature gas-cooled SMRs at Dow's Seadrift, TX facility — first industrial SMR heat + power application in US.
- 2024
Natura Resources proposes SMR on Lake Limestone site (decommissioned coal plant). ERCOT interconnection study underway. Coal-to-nuclear brownfield reuse model.
- 2024
Last Energy deploys microreactors (20 MW) for industrial / datacenters. Multiple TX site agreements signed. Targets 2026 first power.
- 2025

ERCOT Grid Architecture — The Lone Grid
ERCOT operates as a nearly island grid — intentionally separate from Eastern and Western Interconnections to avoid FERC federal rate regulation. This creates both freedom (market innovation, fast interconnection) and fragility (no emergency imports during Winter Storm Uri).
Strengths
- Fastest new generator interconnection queue in US (~1–2 years vs 5+ nationally)
- Real-time nodal market pricing — efficient dispatch
- Energy-only market drives competitive investment without capacity payments
- ~5 GW battery storage installed by 2024 (among largest US state fleets)
Vulnerabilities
- Winter Storm Uri (2021): Grid within 4 minutes of total collapse. 246+ deaths.
- ~1.1 GW only ties to neighboring grids — no real emergency backstop
- Summer peak demand growing ~2 GW/year (datacenters + EVs)
- Gas supply chain freeze risk remains despite weatherization rules

Sector Decarbonization Timeline
- 2024
Wind surpasses coal in annual generation (ERCOT). Solar growing at 5+ GW/year. Battery storage at 5 GW and accelerating.
- 2026
First SMR power-purchase agreement signed for industrial heat (Dow/X-energy Seadrift). Sets template for petrochemical decarbonization.
- 2027–29
~7 GW coal retirement wave. Coal drops below 5% of ERCOT. Transmission bottlenecks in Permian limit additional wind additions.
- 2030
Renewables + nuclear plausibly reach 60% of ERCOT generation under market trajectory. Gas still dominant in peak hours. No state carbon mandate.
- 2032
Offshore Gulf of Mexico wind leases develop — first Texas offshore wind farm (projected 500 MW to 2 GW). Hydrogen electrolysis pilots using stranded Permian wind.
- 2035
IRA clean energy tax credits expire (or extended). Without mandate, gas retains ~35–40% share. With federal carbon price, gas drops to <20%.
- 2040
Green hydrogen from Permian Basin wind/solar potentially competitive for industrial and LNG-to-hydrogen export. Corpus Christi H₂ hub development.

The Texas Energy Paradox
Texas is simultaneously the greenest large grid in the US by wind penetration and the largest state emitter by both absolute and per-capita GHG. This paradox reflects two parallel economies that barely intersect:
The Clean Economy
- $50B+ annual wind + solar investment
- 40 GW wind — more than Germany per capita
- Battery storage growing fastest in US (ERCOT economics)
- Clean energy employs ~250,000 Texans
- Wind LCOE ~$20–25/MWh (cheapest power in US)
The Fossil Economy
- ~$350B/year oil & gas production value
- Texas produces more oil than Iraq (5.6M bbl/day, 2023)
- ~900,000 direct oil & gas jobs
- LNG exports: 70+ Mtpa capacity, growing
- No state income tax — revenue depends on severance tax

★ Green Cement — Texas Has the Best Position in the US
Texas uniquely combines every factor needed for low-carbon cement leadership. No other US state comes close to matching all five drivers simultaneously:
1. Limestone
The Edwards Plateau (Central TX) is one of the largest accessible limestone formations in North America — 200 miles wide, high purity calcium carbonate, shallow overburden. Already feeds TXI, Vulcan Materials, Martin Marietta.
2. Cheap Clean Energy
Wind at $20–25/MWh and solar at $25–30/MWh in West Texas make electric kiln and plasma kiln operations economically viable — cement clinker requires 3–4 GJ/tonne of heat. TX wind + solar is cheapest in the US.
3. CO₂ Sequestration
The Permian Basin has 200+ GT CO₂ storage capacity — the world's largest saline aquifer and depleted reservoir complex. Cement kiln CO₂ capture + Permian sequestration is the lowest-cost CCS pathway in the US (~$40–60/tonne).
4. Construction Demand
Texas is the fastest-growing US state — 500,000+ new residents/year, 200,000+ housing starts, $100B in infrastructure projects. TX consumes ~12–15 MT cement/year, importing from Mexico and Louisiana. Domestic green cement commands premium pricing.
5. Industrial Ecosystem
Fly ash from retiring coal plants provides SCM (supplementary cementitious material) to reduce clinker ratio. Steel slag from Nucor Jewett. Silica fume from Elkem Corpus Christi. Full SCM supply chain within TX borders.
Market Opportunity
Green cement commands $30–80/tonne premium vs grey cement ($100–130/tonne). US green cement market projected $8B by 2032. Buy American provisions in IIJA + IRA favor domestic low-carbon concrete. First mover captures Buy Clean CA + TX infrastructure contracts.

| Carbon Capture (DAC) | Permian sequestration + 45Q tax credits | Lowest-cost storage geology in North America | $3–8B/yr by 2035 | 2026–2035 |
| EV + Grid Storage Manufacturing | Battery supply chain + CHIPS/IRA incentives | Growing but California/TN/GA ahead on EVs | $5–15B investment by 2030 | 2025–2030 |
| Methane Reduction Credits | Orphan well plugging + Permian monitoring | Huge inventory but regulatory lag | $2–4B/yr by 2030 | 2025–2030 |
