Thanks, Dave. While macro conditions have proven challenging of late, particularly in the wind power sector, I continue to be encouraged by our team's execution, and I'm pleased that we once again meet our financial objectives in the second fiscal quarter.
We cut our net loss and cash usage significantly year-over-year. We also reduced our adverse purchase commitments by over 30%, with most of the remainder to be settled this quarter as Dave just mentioned a couple of minutes ago. And as expected, our top line remained roughly flat year-over-year as a decline in revenues from our Windtec Solutions was offset by higher revenues from our Gridtec Solutions.
Our Windtec Solutions include both products and services for wind turbine manufacturers. The products are a set of power electronics and controls that act as the brain of the wind turbine. We call our fully integrated set of products ECS or electrical control systems. And our services include proprietary wind turbine designs, certification support, as well as on-site training for manufacturing, testing, quality assurance, commissioning and supply chain management. These services allow manufacturers to rapidly introduce new wind turbines or upgrade existing turbine platforms to gain competitive advantage and market share.
2012 has proven to be a time of great change in the wind industry as a whole. In China, which has installed nearly half of the world's wind turbines in recent years, the government has greatly increased its oversight of projects in the sector in order to resolve grid-related issues. In fact, virtually all wind farm projects now must get formal approval from the central government before beginning construction.
Ultimately, this is a change for the better, one that will ease grid interconnection issues and make projects more predictable. But looking at the here and now, the abrupt change in policy has hit all wind turbine manufacturers in China hard.
As a reminder, our customers in China include: JINGCHENG New Energy, or JCNE; Shenyang Blower Works, or SBW; Dongfang Turbine Company; and XJ Group. Both JCNE and SBW are taking a vertical approach to the market, not only manufacturing wind turbines but also developing wind farms.
XJ Group is a large, well-respected player in the T&D market. And they are wholly owned by State Grid, which controls about 90% of China's electricity network. And Dongfang has been a leader in China's power generation market and a leading producer of wind turbines. We continue to work closely with these companies as they implement their respective strategies and navigate through the industry-wide changes taking place today.
Our strategy is to enable each of them to field highly reliable, multi-megawatt wind turbines, systems above and beyond the 1.5-megawatt turbines that have dominated the Chinese market. And we also want to ensure that these turbines are best in class when it comes to both power quality and grid compatibility.
JCNE is a good example. Early last year, JCNE licensed multiple wind turbine platforms from AMSC, ranging from 2 megawatts to 5 megawatts. Their initial focus has been on our 2-megawatt wind turbine, featuring a full conversion drivetrain. These differ from many wind turbines in China that are called doubly fed machines. In doubly fed turbines, only some of the power passes through the converter system. In JCNE's turbine, all of the power produced flows through the power converter system, ensuring very high power quality and a greater ability to support the transmission grid.
We are looking for JCNE to continue building its order book for this 2-megawatt turbine. And JCNE plans to showcase the 3-megawatt turbine that we licensed to them at this month's China Wind Power conference in Beijing. From a financial perspective, JCNE contributed more than 25% of AMSC revenues in the second fiscal quarter.
Similar to China, India's wind power market has been undergoing significant changes in 2012. In recent years, this market replied upon a tax credit system that provided tax breaks on wind projects, regardless of the performance of those projects. Now the world's third largest wind power market behind China and the U.S., India is transitioning to a generation-based incentive for wind power that rewards project developers for maximizing their power output and lowering the cost of energy.
Again, this is clearly a change for the better. And it favors AMSC, given the strong performance and competitiveness of our turbines. But it has also temporarily dampened installation. Industry analysts believe India's installations in 2012 could be down by 20% or more from 2011 before beginning to rebound.
In the midst of this challenging environment, Inox, our wind turbine manufacturing partner in India, has performed extremely well. They recently produced their 100th 2-megawatt wind turbine and are now among the top wind turbine manufacturers in India. Similar to JCNE and SBW, Inox is taking a vertical approach by not only manufacturing wind turbines, but also developing and operating wind farms, providing a nice built-in channel to market.
In comparison with China and India, the wind market in South Korea remains stable. We generated about 10% of our Q2 revenues from this market, working with companies like Hyundai Heavy Industries and Doosan Heavy Industries, both well-recognized multibillion-dollar corporations. Both Doosan and Hyundai Heavy were awarded projects for onshore wind farms in Korea in recent months. They are also well-positioned for the gigawatt scale offshore wind projects that are currently being planned in Korea, and they have an eye to expand into Europe and China.
So in terms of our wind business as a whole, we are supporting our partners strongly. And we are expecting to increase ECS shipments in the second half of our fiscal year based on our existing backlog and ongoing conversations with our customers regarding their growth plans.
Performance in our grid segment was solid in the second fiscal quarter, as we generated 20% year-over-year increase in revenues. Driving this growth was our D-VAR product line, which helps to stabilize voltage for electric utilities, renewable energy power plants and industrial operations. In Q2, Australia was again a key market for us on the D-VAR front, contributing nearly 20% of our total revenues. Our sales team also continues to make good headway with D-VAR bookings. In fact, we are now nearly fully booked for this product line through the end of fiscal year 2012.
The second fiscal quarter was an eventful time for our wire and cable business as well. For those that are new to AMSC, we are the world's leading producer of high temperature superconductor wire. This wire is being used to develop and manufacture a wide array of systems, from power cables and surge suppressors for the electric utility industry, to generators for wind turbines, to motors and defense systems for naval ships.
On recent calls, I've spent a good deal of time discussing the progress we have made in boosting our superconductor wire production and yield while also streamlining our costs. We have been shipping industry-leading volumes of superconductor wire to customers around the world. This wire has been offered in a range of 70 amps to 100 amps, or about 100x the amount of power that a copper wire of the same dimensions can carry. That's a huge performance advantage over conventional conductors. And that advantage just got a whole lot bigger.
While our manufacturing personnel here in Massachusetts were increasing our production and yield, our R&D staff were focused on boosting wire performance while also maintaining our industry-leading capacity. That's no small feat. However, the team effort led to a breakthrough. AMSC is now offering wire with demonstrated performance up to 200 amps, effectively doubling our wire performance. This puts us right on track with the goals that the U.S. Department of Energy set for high temperature superconductor wires years ago. And it is worth noting that we accomplished this recent jump in performance at the same time that government support for wire development was withdrawn.
What does the boost in performance mean for the customer? Most importantly, lower system cost. This will happen in 2 ways. First, manufacturers will be able to spend less on superconductor wire. And they will also save on other raw materials by making their systems even more power dense and compact. And what does this mean for AMSC? Well, we've certainly never been in a stronger competitive position in terms of wire production, pricing and performance. And this breakthrough should help to broaden our addressable market.
The 2 biggest factors that have been inhibiting market growth for superconductors are cost and customer adoption. We believe the availability of our new wire will help manufacturers continue to lower the cost of superconductor power cables, fault current limiters, motors, generators and defense systems. And as that is taking place, we will continue to move through the customer adoption cycle and do all that we can to accelerate it. And I will discuss in just a minute the impact of last week's super storm and how it may play an important role in this.
Remember that we are dealing with some of the most risk-averse customers in the world, most notably electric utilities and the U.S. Navy. However, with successful Navy motor and degaussing systems tests now complete and successful superconductor power cable installations now behind us in countries like the United States, Korea and China, comfort and interest continues growing worldwide.
The latest example of this is Power Grid Corporation of India, or Power Grid for short. Power Grid is one of India's largest companies and is responsible for about half of the country's transmission operation and infrastructure. At Power Grid's annual general meeting, which was held in September, the company's chairman discussed how superconductor cable systems, and I quote, "Offer very high power carrying capacity at lower voltage, besides extremely low losses, for effectively addressing right-of-way issues." In fact, the chairman included superconductor cables as 1 of the 2 technology leadership areas that Power Grid is exploring, with ultrahigh-voltage AC overhead power lines being the other area of interest. Comments like this are exciting because they demonstrate that superconductor cable technology is now a part of Power Grid's plans to upgrade India's electrical network.
And as Hurricane Sandy reminded us yet again, we need to make significant investments to not just replace but also upgrade our electrical grid right here in the U.S. Those of you who didn't see it in person here on the East Coast have probably seen wall-to-wall coverage of sparking power lines, exploding substations and widespread blackouts. Incidents like these, as well as national security concerns, continue to reinforce the fact that our infrastructure is antiquated and is in desperate need of upgrade. New solutions are available and action is required.
Utilizing underground superconductor power cables in urban and metropolitan areas will enable us to continue increasing power flows, and it will keep those power flows out of harm's way. And bolstering the grid with D-VAR systems, fault current limiters and fault-current-limiting cable systems will enhance network reliability and resiliency.
In fact, we've been working with ConEd in New York to demonstrate one of these fault-current-limiting cable systems. FCL cables can be used to connect multiple substations together. So if one goes down, the others can pick up the slack and help keep the lights on for everyone. Other utilities have expressed an interest in the same type of solution, this same network approach to power. New policy and additional funding can help to speed the adoption cycle and we're continuing to work alongside American utilities in Washington to advance this issue and to solve this critical problem.
So in summary, AMSC is meeting its core objectives. Our revenue stream remains geographically diverse, with key contributions coming from Australia, China, India, Korea, the United Kingdom and the United States. We're positioned for a stronger second half of the fiscal year and we are encouraged about our long-term business prospects. We are committed to reducing our cash usage and enhancing our financial performance. And we'll continue to closely monitor our core markets and our spending to ensure that happens. Now Toya, would you please open the call to questions from our audience?
