Key US wind power trends and metrics to track: Maguire

Wind farms have created a record share of U.S. electrical power production so far in 2024, and are the 2nd biggest source of clean power behind nuclear plants in the U.S. generation system.

Lacks of parts, leaps in labour costs and drawn-out advancement timelines have slowed the pace of wind farm building in the last number of years.

However recent drops in advancement expenses plus rewarding tax credits set to appear in 2025 have actually revived wind task development in 2024.

That ought to even more elevate wind power's status in the U.S. generation mix, and establish wind farms as an essential pillar of the U.S. energy system over the coming years.

Below are some of the key patterns and data points that can assistance track the ongoing development of this crucial power source.

GROWING FOOTPRINT

Current installed wind generation capability in the U.S. is approximately 152 gigawatts (GW), according to the U.S. Energy Info Administration (EIA).

That capability is up 46% from 2019, and is 135% more than 10 years back.

For the past years, U.S. yearly wind capability growth has averaged 9%, which is somewhat more than Europe over the exact same period, however slower than the global average of 13% a year, according to Cinder.

The U.S. growth speed is likewise far slower than the 19% a year growth published by China, the world's top wind manufacturer.

Still, the U.S. ranks second in regards to total wind capacity behind China's approximately 441 GW, and ahead of Germany (69. GW), India (45 GW) and Spain (31 GW) on the leading 5 list.

CHANGING POWER MIX

The consistent climbs in U.S. wind generation capability has. led to a major swing in the nation's generation mix.

Wind power represented an average of 15% of capability. additions to the U.S. power system from 2000 to 2010, and 27% of. capability additions given that 2010, according to EIA information.

Integrated solar and wind capacity accounted for around 60% of. U.S. power capacity additions because 2010, highlighting the drive. towards tidy energy in the U.S. over that time.

As of 2023, wind power accounted for 12% of U.S. electrical power. generation capability, compared to 11% for solar, 8% for. nuclear, 7% for hydro, 16% for coal and 43% for gas,. Ash data programs.

STATE & & SYSTEM SPAN

Texas is by far the largest wind power producing state,. accounting for 28% of total installed capacity in 2023,. according to EIA.

Texas' nearly 42 GW of wind capability compares to 13 GW in. Iowa, 12.6 GW in Oklahoma, 9 GW in Kansas and 8 GW in Illinois,. which are the top 5 states by wind capacity.

In regards to wind power's share of the power created in. each state, Iowa has the biggest wind share of almost 60%.

South Dakota (55%), Kansas (46%), Oklahoma (42%) and New. Mexico (38%) round out the leading five. Texas produces 22% of its. state power from wind.

At the system level, the Southwest Power Pool - which covers. 14 states stretching from Oklahoma to North Dakota - generates. around 37% of its power from wind farms.

The Electric Dependability Council of Texas (ERCOT) system has. the next largest wind share of 24%, followed by the Midcontinent. Independent System Operator (MISO) system, with 14%.

TALLER, WIDER & & CHEAPER The size and scale of wind generation systems have grown. together with capability.

The average nameplate capability of U.S. wind turbines in 2015. was 2 megawatts (MW), according to data from the American Clean. Power Association (ACPA) and the Lawrence Berkeley National. Laboratory (LBNL).

That typical capability leapt to 3.4 MW by 2023, fuelled by. increases in the average size and height of the rotors and centers. which power each turbine.

The typical size of a turbine rotor - which holds the. blades and turns to create power - has actually increased 31% from an. average of 102.4 meters (336 feet) in 2015 to 134 meters (440. feet) by 2023.

The average height of a turbine hub - the primary turbine. drivetrain - has actually also increased, from around 83 meters (272. feet) in 2015 to 103 meters (337 feet) in 2023.

Wind turbine systems have actually become less expensive.

The typical worldwide rate of a turbine sold by Vestas. - among Europe's biggest turbine producers - has. dropped from around $1,700 per kilowatt hour (kWh) during 2010. through 2014 to around $1,050 per kWh since 2018, according to. LBNL.

That's resulted in a more than 35% drop in the. capacity-weighted typical cost of a wind job, from around. $ 2,600 per kWh from 2010 through 2014, to around $1,650 because. 2018.

Lower turbine and generation expenses have in turn helped lower. the so-called levelized cost of wind power production, which. enables comparisons of generation expenses by power source as soon as. tasks are completed.

In 2023, a normal power purchase contract readily available to. energy project developers had wind power costs at around $26 per. megawatt hour (MWh), according to LBNL.

That compared to $37 per MWh for a utility-scale. photovoltaic solar farm, and around $28 for a combined cycle. gas plant, and means that wind currently ranks as one of. the most affordable kinds of power in the nation.

And with more wind task construction underway, and strong. competition among turbine makers serving to keep wind system. rates under pressure, additional cuts to generation expenses are. likely. << The opinions expressed here are those of the author, a. writer .>
