Al Mirfa Power & Distillation Plant
plant was to includes 4 Siemens (64.3V) gas
turbines, each with the capacity of (48 MW).
Electric Power is produced by generators at (11
KV) and is stepped up to (33 KV) for local
distribution, and up to (220 KV) for the high
voltage transmission system.
Four waste heat recovery Boilers (WHRB) with
a capacity of (120 T/h) each, in addition to 2
Aux. Boilers with a capacity of (220 T/h)
(Manufactured by MACCI) and additional 2 Aux.
Boilers with a capacity of (170 T/h)
(Manufactured by CCT) are used to produce steam
at (2300C) & (16)bar pressure.
Steam pressure is then reduced to (1.5) bar &
(1100C) to be utilized in 3 desals with a
production capacity of (5.4 M.G.D). each &
another 3 desals with a production capacity of
(7.5 M.C.D) each.
Distilled water is chemically treated on site
for healthy and potable drinking supply
according to WHO (Word Health Organization)
Three 10 million gallons tanks store some
water on site, and the rest is pumped to the
local water distribution of the main water
Madinat Zayed Power Plant:
Madinat Zayed power plant was commissioned in
1977 as a diesel generator station with three GM
model 20-645E4 units of (1.5 MW) capacity each.
Additional two GM Diesels of a like
output were added in 1983 to give a total
capacity of (7.5 MW).
- In 1991 a Stewart & Stevenson Model LM
2500 derivative turbine generator of (18 MW)
capacity was installed.
- In 1993, two frameľ6 EGT gas turbines
with a capacity of (30MW) for each were
added to the plant.
- In 1996, a decision was made to
decommission the power plant at Liwa and
relocate the Stewart & Stevenson unit from
there to Madinat Zayed. This unit is
identical to the other unit at Madinat Zayed
which was installed at Liwa in 1991 A Kanis
Frame-5 gas turbine originally installed at
Liwa in 1992 of (22MW) capacity was also
relocated to Madinat Zayed at the same time.
The Current installed Capacity at Madinat
Zayed is (118MW) as one of the Diesel generators
has been decommissioned.
Electricity is generated at (11KV) and
stepped up to (33KV) for local distribution &
stepped up to (220Kv) for interconnection to Al
Mirfa and Abu Dhabi.
In 2003 The energy output represented the
expected plant factors for Al Mirfa and Madinat
Zayed (of 72 % and 28% respectively).
In the year 2003 the plant availability was:
- Al Mirfa gas turbines
- Madinat Zayed Gas Turbines
