Thermoelectric
power station
Wind power

Solar power

3. In Latvia 70% of all Electrical
Power is Made by 3 Big HEPPs

4. HISTORY OF ELECTRICITYHISTORY OF ELECTRICITY
• The first time electrical phenomena was
described in Greece most probably in the
17th century.
• People who were related to electricity
history :

5. History of Electricity in LatviaHistory of Electricity in Latvia
In Latvia people started to use the electrical
energy in 1970. The first electricity companies
were found in 19.-20. century. 1939 – the
beginning of Latvian power system. In 1955
more power stations began to operate.

6. About electricity nowadaysAbout electricity nowadays
In Latvia there are still some estates where is
no electricity (in Latvia 0,1 % people do not have
electricity), because :
•some houses are located
far from inhabited centers;
• people do not have money
to pay for the electricity.

7. HEPPsHEPPs
HEPP is power station which uses water to
produce electricity. Hydroelectric power
stations produce about 7% of the world energy.

8. Small HEPPs in Latvia
Small hydropower stations began to develop
in 1950. From 1945 to 1960 were built 20
small rural HEPPs . In 1998 35 small
HEPPs operated in Latvia .

9. ADVANTAGESADVANTAGES
IT IS A RENEWABLE ENERGY
+ Hydroelectric produces much electricity;
+ Energy is rather cheep;
+ The pollution is minimal;
+Stations can operate for many years;
+ They are more economic for home owners than solar
power;
+ People will have workplace (decrease the rate of
unemployment);
+A HEP produces about 500 Kw per hour, but each family
consumes about 200 kw per month.
+ In this river is little fish, so the fish will not suffer as it
happens on larger rivers during the spawn (for example,
salmons)

10. DISADVANTAGESDISADVANTAGES
- HEPs will flood neighborhood, bigger
areas would be under water;
- Careless people can drown;
- The construction of dam is rather
expensive

11. Small HEPPs in Latvia - 143

12. In Daugavpils region there are
3 Small HEPPs
Galvāni HEPP
Šķivišķi HEPP
Dubeņeca HEPP

13. Fild Trip to Galvāni HEPP
What is it???
Wow, what a
construction!

14. Girls find it
interesting too 
We must see
everything…
We must poke our
noses into everything
Oh, a really good
fishing place!

15. Meeting the owner
Danger
We have to see all
constructions

16. On the way home-
I’ve got an IDEA!
If there are
small HEPPs in
Ambeli
Why not in
Shpogi?...

17. Why?
1. Cheaper electrical energy for 2
schools, ambulance, municipality hall
and 2 shops.
2. New work places
3. Cleaner environment

18. Where?
Near Špoģi
on the
river
Dubna

19. There is already a
dam.
It is possible to get
faster flow
It would not disturb
the kids to relax on
the banks of the river
PLUSES

20. MINUSES
It would flood gardens and
pasture.
Fishermen would lose
fishing places.

21. Where?
On the
other
side of
the
village

22. PLUSES
There is a purification plant
Is it really a
plus?

23. MINUSES
5 bathing places would
flood.
Fish farm ponds would flood.
Swans and ducks would have to
search for new places for
living.

24. CONCLUSIONCONCLUSION
There are more advantages than
disadvantages. We asked our neighbors, if a
HEPP is necessary in Shpogy. Here are the
results:

25. We must work!
1. Assess all + and –
2. Enroll into RTU (Riga
Technical University) to
study energetic and
electronics
3. Make a business plan and
rise EU fund
