(Attached to Resolution No. 83/2018/NQ-HĐND
dated 11th July 2018
of Lam Dong Provincial People’s Council)
PART I
OBJECTIVES AND GENERAL ORIENTATION
I. Objectives
1. Objectives: The development of power shall ensure
a harmony of the supply source and the grid system to meet Lam Dong Province’s demands
of socio-economic development, national defense and security.
2. Specific objectives: Attention shall
be paid to the harmonious development of the electricity transmission and
distribution grids to satisfy the targets of Lam Dong socio-economic
development with the growth rate of GRDP at 9%/year in the 2016 -
2020 stage; 8.5%/year in
the 2021 - 2025 stage; and 8%/year in the 2026 - 2035 stage, particularly (see appendix 1 attached)
a) By 2020: Maximum output: Pmax
= 323.6 MW; commercial electricity: 1,607 million kWh; the growth rate of commercial
electricity in the 2016 - 2020 stage will be 11.84%/year.
b) By 2025: Maximum output: Pmax
= 524.4 MW; commercial electricity: 2,682 million kWh; the growth rate of commercial electricity
in the 2021 - 2025 stage will be 10,79%/year.
c) By 2030: Maximum output: Pmax
= 772 MW; commercial
electricity: 4,130 million kWh; the growth rate of commercial
electricity in the 2026 - 2030 stage will be 8.96%/year.
d) By 2035: Maximum output: Pmax
= 1,090 MW; commercial electricity: 6,064 million kWh; the growth rate of commercial
electricity in the 2031 - 2035 stage will be 8.29%/ year.
II. General orientation
1. The development of electricity grids and
distribution of power loads must satisfy the requirements of power quality, and
the electricity supply must win the trust in community.
2. The development of electricity grids
must go with the putting of electricity plants into operations to obtain general
effects in investment of the national and regional electricity systems; and be suitable with the electricity
industry’s development strategy, electricity development planning, and other
local and regional plannings.
3. Develop the 220kV and 110kV
electricity grids, improve the regional electricity network to obtain the trust
in electricity supply, reduce losses in distribution lines, and improve the
22kV supply lines to supply electricity for remote areas.
4. Build electric transmission lines
with expectation of long-term development; use steel electric posts strong
enough so that numerous lines of electric voltages can be hooked separately on
the same row of electric posts rather than building more posts; Cities, towns, and places can be huge
sources of power demand, which requires reserves and flexibility, and load cables
buried underground.

transmission grids shall satisfy the requirements of N-1, reducing energy
losses.
2.2. Criteria on sources of electricity:
- Sources of electricity supply for the
province shall meet the needs of energy consumption effectively including any
backup as stipulated;
- Sufficient capability of contribution
to the regional electricity network;
- Ensure sufficient supply of
electricity in case of any incident;
- The 110 kV network is ensured to satisfy N-1;

- Gradually increase the people’s trust
in electricity supply;
- The structure of electric grids must
satisfy the requirements of electricity supply in which a backup system is
ensured and the structure is not overloaded in the future.

planning to develop a new planning to accord with the general planning of Lam
Dong Province;
- The 22kV grids must also meet the
standards of N-1 and try to reach the low voltage grids and transformers;

- The 110 kV feeders composed of cables of AC-185 to AC-400 or AC-185 or AC-240.
In terms of reduction of land over-occupation
by electric posts, top priority shall be given to using steel electric posts
strong enough so that numerous cables of electric voltages can be hooked
separately on one row of electric posts rather than more posts; In addition, in a case where there is
difficulty in clearance and making compensations, the exising feeders might be re-used
and upgraded.
(2) Transformer stations:
- Each station 220 kV and 110 kV is designed in a way where a transformer
can receive either of the supply sources in case one source may be out of order;
- Transformers: Transformers with a capacity from 125 to 250 MVA for the 220 kV grids shall be used and from 25 - 63
MVA for the 110 kV grids, to satisfy the demands at each
transformer, ensuring 50-70% of the installed capacity. Transformers must be

IV. Estimated electricity demands in districts, city of Lam Dong Province in
the planning period
(According to Tables 1, 2 and 3 attached)
V. Provincial planning on medium and small electricity source development
and 220kV transformer sources
(According to Table 4 attached)
VI. Connecting the grids to adjacent provinces:
Lam Dong Province’s electricity
system during the past has been provided by the national electricity system as
follows:
1. The source of 220 kV from the electricity system,
including the 220 kV
feeders: Bao Loc - Song May, Bao Loc - Hydraulic Electricity Ham Thuan, Bao Loc - Phan Thiet, Di Linh - Bao Loc, Di Linh - Hydraulic Electricity Dong Nai
2, Di Linh - Hydraulic
Electricity Dai Ninh, Da
Nhim – Duc Trong - Di
Linh and other in-situ-sources
from 500/220 kV - 450 MVA Di Linh station
and the Da Nhim Hydraulic Electricity (4x40 MW), to supply electricity for the 220 kV Da Nhim station with a capacity of (2x63)
MVA, the 220 kV Bao Loc station with
a capacity of (63+125) MVA and
the 220 kV Duc Trong
station with a capacity of 125 MVA;
2. The 110 kV electricity networks: Most districts and cities have their 110/22
kV transformers to supply electricity
for households’ electricity loads. The 110 kV stations receive their main supply
sources from the three aforesaid 220kV stations, and the 110kV lines cables are
also connected with ring circuits. As a result, the stations can receive
electricity from the two sources, confirming that customers can trust in the
electricity supply source satisfying the standard N1.
However, some zones still haven’t had
110kV transformer stations (in District of Da Huoai, Cat Tien, and Dam Rong).
The 110 kV electricity network of Lam Dong
Province has connected to Dong Nai Province through the 110 kV Da Teh - Tan Phu feeder.
3. The medium electricity network during
the past has seen a relatively-impressive improvement. The total amount of
electricity distribution has been increasingly going up to meet well the
provincial demands of electricity.
However, due to the terrain among the
districts, there is a lack of their cooperation in electricity support.
