The $59.5m solar system built on McGraw-Hill’s East Windsor, New Jersey campus.

The system will generate enough electricity to offset the need for other energy sources to run McGraw-Hill’s offices in East Windsor.

The solar array is expected to produce 18.4 million kWh annually, eliminating an estimated 12,689 metric tons of carbon equivalent emissions from the atmosphere annually.

In addition, NJRCEV placed other projects into service during the first quarter of fiscal 2012, including the 3.6MW project at the Village of Manalapan, the remaining 25% of a 4.7MW system in Vineland, New Jersey and the 1.3MW system across two rooftops in Edison, New Jersey.

The 3.6MW project is a $17.2m, ground-mount solar project located in Manalapan, New Jersey, and is expected to produce 4.5 million kWh annually.

The remaining 25% of the solar project in Vineland completes the 4.7MW, $22.3m, ground-mount solar project.

The solar array is expected to produce 7.2 million kWh annually, eliminating an estimated 4,950 metric tons of carbon equivalent emissions from the atmosphere each year.

Finally, two rooftop systems in Edison, totaling 1.3 megawatts, were commissioned.

These systems represent an aggregate $6.4m investment and are expected to produce 1.5 million kWh annually.
