NS Power and OpenHydro Successfully Deploy in-Stream Tidal Turbine in the Bay of Fundy

HALIFAX and PARRSBORO, Canada, November 12 - NS Power and its tidal technology partner OpenHydro have successfully
deployed the first commercial scale in-stream tidal turbine in the Bay of
Fundy today. The one-megawatt commercial scale turbine reached the Fundy
Ocean Research Centre for Energy (FORCE) deployment site, in the Minas
Passage, yesterday afternoon and began preparations for deployment. The
turbine was fully deployed just before 2:00 today and is now operational,
rotating with the tides, collecting data, and producing energy.

"Today begins a very important period of testing that we believe will
demonstrate that tidal energy can be part of Nova Scotia's renewable energy
future," said Rob Bennett, President and CEO of Nova Scotia Power. "Working
with OpenHydro, we are proud to be the first to deploy and test a commercial
scale tidal turbine in the Bay of Fundy and look forward to the learnings
ahead."

The turbine's journey from Halifax to the deployment site, located
approximately three kilometres off the shore of Black Rock, took 7 days. Once
on site, the 400-tonne device was lowered in less than six hours to its
intended location on the ocean floor by the purpose-built barge called the
OpenHydro Installer. The barge and the deployment method were both designed
and developed by OpenHydro.

"Today is an historic first for Nova Scotia," said James Ives, CEO of
OpenHydro. "For the first time, thanks to Nova Scotia Power's foresight and
OpenHydro's technology, a commercial size in-stream tidal turbine has been
successfully deployed in what is undoubtedly one of the world's strongest
tidal energy resources."

The turbine now rests on the seabed held in place by a subsea gravity
base designed by OpenHydro and fabricated by Cherubini Metal Works, a
Dartmouth based company.

Nova Scotia Power's involvement with this tidal energy test facility is
supported by Sustainable Development Technology Canada (SDTC), an
arm's-length, not-for-profit corporation created by the Government of Canada.

About OpenHydro

OpenHydro is an Irish energy technology company whose business is the
design and manufacture of marine turbines for generating renewable energy
from tidal streams. The company's vision is to deploy arrays of tidal
turbines under the world's oceans, silently and invisibly generating
electricity at no cost to the environment. OpenHydro has achieved a number of
industry firsts including being the first to deploy a tidal turbine at the
European Marine Energy Centre (EMEC), the first to connect to and generate
electricity from tidal streams onto the UK National Grid and the first to
successfully demonstrate a method of safely and economically deploying
turbines directly on the seabed. The deployment method uses a custom built
heavy lift barge designed by OpenHydro specifically for deploying tidal
turbines which delivers a step change in the economics of tidal energy.

OpenHydro has a project portfolio spanning the USA, Canada, France and
the Channel Islands with utility partners including EDF and Nova Scotia
Power. OpenHydro has won a number of awards for its innovations in the field
of renewable energy technology. For further information please visit
