RTR1L8X7.jpgHara, a Silicon Valley startup that makes environmental and energy efficiency software, has signed a deal to provide its technology to the state-run Abu Dhabi Water and Electricity Authority.

The company on Monday said its technology will be used to monitor and manage the energy use of some 200,000 businesses and homes in Abu Dhabi. The water and electricity authority serves 1.4 million customers.

Hara, backed by venture capital firm Kleiner Perkins Caufield & Byers, claims Abu Dhabi will save $3 billion in costs over the next decade, forestalling the need to build several 500-megawatt natural gas-fired power plants.

Terms of the deal were not disclosed, though Hara, based in San Mateo, Calif., described it as a “multi-year, multi-million dollar” agreement.

“The Abu Dhabi economy is achieving rapid growth which makes it vital for us to make the best use of our natural resources,” Sheikh Diab Bin Zayed Al Nahyan, the water and electricity authority’s chairman,” said in a statement. “Our new environmental and energy management solution from Hara will facilitate and accelerate the implementation of alternative strategies for energy efficiency and natural resources using optimal sustainable methods, as well as reduce the Emirate’s carbon footprint and energy consumption.”
