altPOWER Completes PV System to Help Power the Rockefeller Center Christmas Tree System
is the largest privately owned PV installation in Manhattan.

November 29, 2007 - New York City Mayor Michael Bloomberg and Tishman Speyer Chairman and CEO Jerry Speyer were on the roof of 45 Rockefeller Center on Tuesday November 20th to celebrate the installation of a 61kW (70 kilowatt DC) solar-electric (PV) system designed and managed by altPOWER. Over the course of a year, the syste m will generate more than enough electricity to power all of the 30,000 LED lights on the tree that will be illuminated during 42 days this holiday season. The PV system will also offset over 2 million pounds of CO2 over its life-time which would have been created had the tree been powered by conventional fuel sources.

altPOWER, working with GE Energy and Tishman Speyer, designed and oversaw the installation of the 61 kWp grid-tied array. The system is located nearly 45 stories up, and it is the highest rooftop PV installation on the planet.

It is composed of 363 GE PV modules and a Solectria PVI 60kW DC-AC Inverter. The project followed an aggressive schedule due to the tree lighting ceremony scheduled for November 28th.

altPOWER President & CEO, Anthony Pereira was delighted that altPOWER played such an important role in the project: "I am proud of the work our team did for this project, under a tight schedule,
and the fact that Tishman Speyer selected altPOWER to undertake this important installation.

This project can have an enormous impact on the future of energy as more and more people,
especially children, hear about the installation and start thinking about the possibilities for renewable energy.

" Mr. Pereira also credited Tishman Speyer for the green initiatives they have undertaken at their properties: "Tishman Speyer's goals to 'Green' Rockefeller Center should be an
inspiration for developers around the world."

At the ceremony, Mayor Bloomberg credited Tishman Speyer for installing a PV system at such an important location: "The tree at Rockefeller Center is one of New York City' s most beloved and iconic landmarks, and with the environmental steps that Tishman Speyer has implemented this year, the 500,000 New Yorkers and tourists that visit the tree each day can dream of a 'green' Christmas."

Mayor Bloomberg added, 'Now they will see an example of green leadership which may inspire them to make greener choices in their own lives.'
