Welcome to the Dolores Wind Farm.

2
00:00:14.806 --> 00:00:19.144 position:25% size:50%
We are located in the state of Nuevo Leon,
on the border with Tamaulipas,

3
00:00:19.519 --> 00:00:24.024 position:25% size:50%
about 80 km from the town of China, Nuevo Leon,

4
00:00:24.149 --> 00:00:28.528 position:25% size:50%
and about 70 km from the city of Reynosa, Tamaulipas.

5
00:00:29.029 --> 00:00:34.284 position:25% size:50%
The wind farm was built on an area of 7,000 hectares,

6
00:00:34.409 --> 00:00:41.791 position:25% size:50%
254 of which were used for the construction of the substation,

7
00:00:41.916 --> 00:00:44.127 position:25% size:50%
platforms and roads.

8
00:00:44.586 --> 00:00:50.592 position:25% size:50%
The construction of this wind farm
required an investment of $280 million.

9
00:00:51.426 --> 00:00:58.183 position:25% size:50%
The wind farm has 83 units equipped with AW-132/3.3 technology,

10
00:00:59.142 --> 00:01:04.564 position:25% size:50%
for a total capacity of 279.3 MW

11
00:01:05.106 --> 00:01:09.402 position:25% size:50%
and a total annual production of 938 gigawatt-hours,

12
00:01:10.445 --> 00:01:16.326 position:25% size:50%
enough to provide electricity to more than 428,000 homes.

13
00:01:16.534 --> 00:01:23.666 position:25% size:50%
It also avoids the emission of 525,000 metric tons of CO2.

14
00:01:24.751 --> 00:01:31.674 position:25% size:50%
The turbines used at the Dolores Wind Farm
are AW-132, generating 3.3 MW.

15
00:01:31.841 --> 00:01:34.594 position:25% size:50%
A unique feature of this turbine model

16
00:01:34.719 --> 00:01:41.142 position:25% size:50%
is that its concrete tower is made up of six sections

17
00:01:41.267 --> 00:01:44.938 position:25% size:50%
that were prefabricated in the city of Monterrey

18
00:01:45.313 --> 00:01:47.857 position:25% size:50%
and it stands 120 meters tall.

19
00:01:47.982 --> 00:01:52.403 position:25% size:50%
Towers are built in concrete to reduce costs

20
00:01:52.529 --> 00:01:55.031 position:25% size:50%
and to reduce the environmental impact.

21
00:01:55.198 --> 00:02:01.996 position:25% size:50%
These turbines start generating with winds of 4 meters per second

22
00:02:02.372 --> 00:02:09.504 position:25% size:50%
and at 10 meters per second,
they reach their nominal voltage of 3.3.

23
00:02:10.171 --> 00:02:16.136 position:25% size:50%
This is the primary substation,
which collects the energy from 83 turbines

24
00:02:16.261 --> 00:02:22.016 position:25% size:50%
through 14 collector circuits and two 34.5 kV busbars.

25
00:02:22.892 --> 00:02:25.353 position:25% size:50%
We have a main transformer that

26
00:02:25.353 --> 00:02:29.482 position:25% size:50%
raises the voltage from 34.5 kV to 230 kV.

27
00:02:30.108 --> 00:02:33.736 position:25% size:50%
Thanks to 79 km of transmission lines,

28
00:02:33.862 --> 00:02:37.240 position:25% size:50%
we’re connected to the Airport Electrical Substation.

29
00:02:37.657 --> 00:02:42.537 position:25% size:50%
Our control room is in charge of
making power generation forecasts,

30
00:02:43.121 --> 00:02:47.458 position:25% size:50%
which are based on wind forecasts from meteorological sources.

31
00:02:48.001 --> 00:02:51.004 position:25% size:50%
We send our forecasts to the National Center for Energy Control

32
00:02:51.337 --> 00:02:55.758 position:25% size:50%
so that we can protect the reliability of the National Electric System.

33
00:02:57.010 --> 00:03:03.474 position:25% size:50%
Enel Green Power, as a socially responsible
company and owner of the Dolores Wind Farm,

34
00:03:04.100 --> 00:03:10.607 position:25% size:50%
is involved in the construction of an
entertainment area for workers living on-site.

35
00:03:11.232 --> 00:03:16.821 position:25% size:50%
In addition, a transportation unit is available for plant personnel

36
00:03:17.322 --> 00:03:21.868 position:25% size:50%
who want to participate in sports and cultural
activities in the community of China, Nuevo León.

37
00:03:22.160 --> 00:03:29.626 position:25% size:50%
A sustainable orchard has been set up to grow tropical fruits

38
00:03:29.751 --> 00:03:33.171 position:25% size:50%
for the workers living on-site to enjoy.

39
00:03:33.338 --> 00:03:38.259 position:25% size:50%
At Enel Green Power, we’re committed
to respecting the environment.

40
00:03:38.384 --> 00:03:42.263 position:25% size:50%
Throughout all construction, operation and maintenance stages,

41
00:03:42.764 --> 00:03:47.060 position:25% size:50%
we’ve been in compliance with environmental standards.

42
00:03:47.185 --> 00:03:50.563 position:25% size:50%
Livestock farming has also continued.

43
00:03:50.813 --> 00:03:58.988 position:25% size:50%
In other words, the land is still being
used to feed animals, like cows,

44
00:03:59.113 --> 00:04:04.327 position:25% size:50%
and landowners can continue their agricultural activities.

45
00:04:04.744 --> 00:04:11.542 position:25% size:50%
Once the wind park’s useful life
comes to an end, it will be restored

46
00:04:11.668 --> 00:04:14.170 position:25% size:50%
and will return to its original state.

47
00:04:14.462 --> 00:04:18.091 position:25% size:50%
The affected areas will be restored and reforested

48
00:04:18.466 --> 00:04:23.263 position:25% size:50%
and will continue to be monitored to
ensure they’re in compliance with regulations.
