Walmart Erects Its First Massive Wind Turbine

Shortly after Walmart announced the installation of solar panels on its 100th store in California, a 265-foot-high wind turbine was erected in Red Bluff, bringing the retail giant one step closer to obtaining 100 percent of its energy from renewable sources.

“It looks like our renewable energy strategy is going to take a lot of tools,” Greg Pool, a director of energy for Walmart, told Forbes. “We are pursuing wind energy and renewable energy at a lot of different levels.”

Supplied by General Electric, the 1-megawatt turbine is the company's first installation of its kind, whereas other stores in California and Massachusetts have smaller turbines, generating under 3 kilowatts of electricity. GE's full sized turbine at Red Bluff is expected to supply 15 to 20 percent of the store's energy and the energy produced from the turbine will be purchased under a 15-year agreement with Foundation Windpower in Silicon Valley.

Walmart is examining other opportunities at locations where turbines would make sense. For many areas, the 25-story machine with blades stretching 250 feet would generate more electricity than a store typically needs—not to mention the headache involved in obtaining permits to install the massive structures. For that reason, it has been suggested by Pool that the wind industry could use more medium sized turbines (400 to 800 kilowatts).

With 180 renewable energy projects in operation, Walmart continues to aggressively pursue renewables. In West Texas, a 90-megawatt wind farm provides 15 percent of power for more than 300 stores and Sam's Clubs, while 17 percent of power in 348 stores in Mexico comes from wind power. In addition to over 140 solar installations in six states, 27 more stores are set to have solar panel installations by 2014.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
