ters (km) offshore, compared to 3 km for
the current project. This will expose it to
the full force of the southern ocean, where
the potential energy is greater. Allen said
Carnegie is currently looking at sites for
10-MW installations.
While feed-in tariffs will be a determinant
in the technology's viability, Allen
said remote island locations could be the
first to benefit from it. " Where electricity
production and potable water are issues
that go hand in hand, and where diesel
power is one of the few options, we expect
the technology to catch on, " he noted.

Beacon Power to Supply Flywheels for
Hybrid Alaska Energy Storage Project.
Beacon Power on May 26 said it will supply
flywheels for a hybrid energy storage
project in Anchorage, Alaska, as part of
an agreement with Chugach Electric Association,
the state's largest utility. Under
the project, Beacon Power's flywheel
energy storage technology will be integrated
with an existing lower-duty-cycle
conventional electrochemical battery for
use during periods when additional energy
is needed. This advanced hybrid energy
storage resource combines the benefits
of fast-responding flywheels with longerduration
batteries to help manage and
stabilize variable output from renewable
energy sources. The 320-kW system will be
installed at a substation next to Chugach
headquarters and is expected to go into
operation later in 2015. The companies
will then test the system to determine if

Aggressive state renewable

inadvertently pushed utilities
in these two states out in
front of proposed, and now
actual, federal policies. One
advantage: Xcel Energy,
which operates in both states,
locked in lower construction
and retrofit costs. Read the full

the new storage solution can be scaled up
in the future to enable increasing amounts
of renewables to interconnect with remote
system utilities along with the Alaska Railbelt.
This will be the third utility installation
of Beacon's modular 160-kW flywheel
energy storage system, which is the next
generation of the 100-kW flywheels in
commercial operation at its 20-MW plants
in New York (NYISO market) and Pennsylvania
(PJM market).
TVO Scraps Olkiluoto 4 Plans. Finnish
utility Teollisuuden Voima Oyj (TVO)
decided not to submit a license application
for the proposed Olkiluoto 4 EPR
before the decision-in-principle made by
the Finnish government and approved
by parliament expired in June 2015. The
utility's board of directors made the decision
on May 13, owing to delays and cost
overruns with the first EPR, currently under
construction in Finland. Olkiluoto 3 is
nine years behind schedule, and estimated
costs have nearly tripled from $3.6 billion
to $9.5 billion.
Botswana Suffers Power Shortages
on Morupule B Coal Plant Failures.
South Africa's power troubles have left
neighboring diamond mining powerhouse
Botswana bereft of electricity. After years
of delays blamed on alleged mismanagement
by contractor China National
Electric Equipment Corp., the country
in 2014 put online the $1.1 billion Morupule
B coal-fired power plant, but the
four-unit, 600-MW facility immediately
suffered breakdowns. At the end of May,
while national power demand peaked at
560 MW with a deficit of 125 MW, only
Units 1 and 2, with an output of 290 MW,
were operating. The country has also been
hit by water rationing that left the Gaborone
Dam about 2% full on May 22.
TEPCO, Mitsubishi to Build Power
and Desalination Plant in Qatar. Japanese
firms Mitsubishi Corp. and Tokyo
Electric Power Co. (TEPCO) announced
on May 25 that they had won a tender to
build and run a 2.4-GW integrated water
and power plant in Qatar. The companies
agreed with Qatar General Electricity
and Water Corp. (Kahramaa) on a 25-year
power and water purchase agreement. The
power and water facilities-which will
use reverse osmosis membrane and multistage
flashing to produce 590,000 cubic
meters of water per day-will be 30%
owned by the Japanese firms, with the
remainder owned by Kahramaa and two
more Qatari state-backed entities. Operations
at the site are due to start in 2017.
TEPCO said the project would enhance its

in the aftermath of the Fukushima
disaster. As the world's third-largest producer
and exporter of natural gas, Qatar's
real economic growth averaged 12.8%
per year from 2007 to 2013, a rate it is
expected to maintain, TEPCO predicted.
Due to this high economic growth, the
demand for power generation and water
desalination has been rapidly growing in
recent years.
Major Tender Awarded for $1.53B UK
Tidal Lagoon Project. British construction
firm Laing O'Rourke is the preferred
bidder for a £200 million ($306 million)
contract to deliver a 410-meter turbine
house and sluice structure block for the
proposed £1 billion ($1.53 billion) Swansea
Bay Tidal Lagoon. The job will require
500 workers at peak construction. Concrete,
reinforcing, and other materials will be
sourced from South Wales. Laing O'Rourke
has named Arup as its lead design and engineering
partner for the contract. The firm
says that following advanced works and
value engineering, a fixed price contract
will be signed later this year for the main
build. Project owner Tidal Lagoon Swansea
Bay Plc has also run tenders for the
project's marine works package and for a
package to provide public realm ancillary
works. The results of these tenders will be
announced soon. Further tenders for the
construction of a turbine assembly plant
in Wales, and for the lagoon's public realm
and buildings work will proceed through
the summer, it said.
AFC Energy Signs MOU for 300 MW
of Fuel Cells in Dubai. Fuel cell firm AFC
Energy on May 2 signed a memorandum
of understanding with the Dubai Carbon
Centre of Excellence that provides a
framework for the assessment and potential
deployment of an estimated 300 MW of
fuel cell generation capacity in Dubai by
the end of 2020. This would be the largest
single fuel cell deployment program in the
world. Dubai Carbon and AFC plan to form
a joint venture that will be responsible for
the deployment of future commercial projects.
In addition to power, the initiative
hopes to monetize water byproducts from
the fuel cell catalytic process.

for a proposed 4,000-MW coal-fired supercritical
power project at Damaracheria in
Nalgonda district in Telangana. ■
