What was the total volume of wind turbine blades produced in China in 2020 
enable our associates to work safely and continue to meet our customers' demands. We also continue to drive the operational imperatives we outlined in 2020 and recommitted to in 2021 to reduce cost and improve our operations globally. We are making very good progress on these imperatives, notwithstanding the challenges created by COVID-19.
Turning to slide six. I'll now give you a quick update of our global operations as well as a market update. During the fourth quarter, we continued to operate all of our facilities at normal levels. In China, we delivered more volume than our original 2020 plan, demonstrating what an outstanding group of associates we have there. However, at the start of 2021, five lines were removed from production, and we expect the remaining lines will run at lower utilization during 2021, and therefore our volumes will be down year-over-year in China. We will continue to explore opportunities for that capacity, including Chinese OEMs, but the shifting of capacity from geography to geography over time is consistent with our strategy to manage risk and optimize our footprint to enable the highest utilization and competitive advantage for TPI and our customers.
In India, we ramped up the first four lines of the facility for Vestas, and we are starting production on two lines for Nordex as we speak. The Vestas ramp went remarkably well, even though we were in the middle of a pandemic. In Turkey, production continued as normal, while we started the transition of three lines during the fourth quarter. That transition is continuing into the first quarter of 2021. In Mexico, production also continued at normal levels. We are currently in the midst of a transition of two lines in Matamoros as well as one line in Juarez. And we plan on having as many as seven more lines in transition in Mexico during 2021. In the U.S., blade and transportation production has continued uninterrupted. On the service side of the business, we made very nice progress in 2020, securing new deals with OEMs as well as asset owners, and are working hard to build out our global service team to execute our growth strategy in 2021 and beyond. To accelerate our growth and to deal with the shortage of qualified technicians, we opened a new training center in Santa Teresa, New Mexico to increase our training capabilities and support our rapidly growing need for qualified blade service technicians. We are also continuing to evaluate blade recycling options and look forward to being able to share more on this effort during 2021 as some significant progress was made during 2020. The global transportation industry is working to rapidly increase the electrification of vehicles to reduce the impact on the environment.
According to BloombergNEF, electric bus sales are anticipated to grow almost threefold in the U.S. from 2021 to 2025. The sales of commercial electric vehicles are expected to grow into the hundreds of thousands by 2030 as e-commerce continues to rapidly rise and consumers are driving demand higher for passenger electric vehicles. We expect there will be an increased demand for composite components and structures for electric vehicles, as composite material systems can be the key material building blocks for purpose-built vehicles. Our composite solutions are ideally suited for transportation applications because of the benefits resulting from weight reduction and therefore extended range for EVs, corrosion resistance, strength, durability, the ability to scale production with lower upfront production investment, and lower total cost of ownership for end users. The level of interest in our capabilities continues to grow. We are collaborating with our customers to develop innovative composite solutions for vehicles across passenger automotive, bus, truck and delivery vehicles.
Today, we are building composite bodies for buses and delivery vehicles, collaborating on Class eight vehicle programs and manufacturing components for multiple passenger EV platforms. Since 2018, we have invested approximately $50 million in our transportatio
