Enerji Sponsors Australasian Cleantech Forum

Following Enerji Limited’s ( ASX: ERJ ) (“ Enerji ” or the “ Company ”) recent strides towards full market commercialisation of the Opcon Powerbox in Australia, the Company is pleased to advise that it is a key sponsor of the 7[th] Annual Australasian Cleantech Forum, held in Sydney from 28 February to 2 March 2011. The Cleantech Forum is focused on presenting cleantech companies to the investor community.

Invited to speak alongside many of Australia’s leading cleantech companies to cleantech investors, this conference follows an exceptional period for the Company, where it achieved a series of crucial milestones including full funding for up to 11 Opcon Powerboxes, a binding commercial power purchase agreement and an MoU with an installation service partner.

As previously disclosed, the first Opcon Powerbox is to be installed at Horizon Power’s Carnarvon Power Station and be generating power and revenue under the power purchase agreement from early 2H this year.

Enerji’s Chief Executive Officer, Greg Pennefather, believes Enerji’s prominent attendance at the Cleantech Forum will help boost industry, customer and investor awareness of the Opcon Powerboxes’ economic and environmental benefits.

“The last 12 months have been momentous for Enerji and I believe the next 12 months will prove to be even more so, as we seek to conclude negotiations with multiple customers regarding further power purchase agreements. Enerji’s achievements really give us something substantial to talk about now” said Mr Pennefather.
