Vietnam
to augment power generation
A new master
plan in Vietnam has mapped out medium-term objectives for investment and
development in the power sector to meet the goal of advancing industrial
capacity.
Under the revised PDP 7, thermal power will account for 45.8 GW of
generation capacity, with still more investment likely in coal power plants
in subsequent years. - Photo petronews.vn
Unveiled in
late March, Vietnam's revised Power Development Plan 7 (PDP 7) sets out a
blueprint for expanding power generation by using a mix of energy sources.
The plan foresees VND3207trn ($148bn) worth of investments in generation and
distribution capacity through to 2030, with installed capacity to rise to
more than 135 GW.
According
to the plan, around $40bn will be invested between 2016 and 2020, of which
75% will be allocated for increasing power generation and 25% will go towards
network development. The remaining $108bn, to be invested between 2021 and
2030, will be similarly apportioned.
A bump in
supply
Vietnam has
about 34 GW of generation capacity, and while this is sufficient for current
needs, it is expected to be outpaced by demand in the near term. Advances in
industrialisation have seen demand growth of 10-12% per annum, placing
additional pressure on the national grid.
In the
short term, the government plans to bridge the gap by importing electricity
from neighbouring Laos. In late January the National Power Transmission
Corporation announced it was in the process of upgrading transmission grids
to accommodate the imports, which are expected to fill the demand gap through
to 2020.
Longer
term, the government aims to revamp the country's energy mix, with coal
anticipated to contribute more than half of total power generated by 2030,
followed by hydropower and natural gas.
Turning to
coal
While
Vietnam plans to ramp up investment in renewable energy, notably wind, solar
and biomass, the use of thermal power is also projected to increase
significantly.
Under the
revised PDP 7, thermal power will account for 45.8 GW of generation capacity,
with still more investment likely in coal power plants in subsequent years.
By 2030,
coal-fired power stations are expected to account for 53.2% of installed
capacity in Vietnam, up from the current 34.4%
"By
contrast, electricity production from renewable energy sources, including
wind, solar and biomass, will only account for about 10% of Vietnam's energy
mix by 2030," Peter Cattelaens, project leader for renewable energy at
the German development organisation GIZ, told OBG.
Meanwhile,
nuclear power will account for about 5.7% of Vietnam's energy mix by 2030
after the country's first nuclear power plant comes on-line in 2028.
As reliance
on thermal power scales up, coal consumption is expected to see a marked
increase over the next 15 years.
According
to some estimates, Vietnam will be burning 188m tonnes of coal per year by
2030, more than double the 79m tonnes projected for 2020 and almost 15 times
the volume consumed in 2012.
Even with
local production forecast to rise from 45.1m to 55m tonnes by 2030, coal
imports – which are typically priced relatively higher – will likely be
needed to bridge a widening supply gap over the coming years.
To that
end, state-owned PetroVietnam has signalled plans to import around 10m tonnes
of coal per year, largely from Australia and Indonesia, from 2017 onward.
Shifting
hydro share
While
hydropower is also expected to see greater investment under PDP 7, competing
needs for water resources and global warming have sharpened the focus on
other sources of energy.
"Hydropower
or coal-fired plants are not sufficient to cope with our growing
economy," Bui Ngoc Bao, chairman of Vietnam National Petroleum Group,
told OBG. "With a changing climate, Vietnam's dependence on hydropower
does not make sense, even if it is competitive investment-wise."
Although
PDP 7 should see hydroelectric generation capacity increase from 17 GW to
27.8 GW by 2030, hydropower's share of the energy mix is projected to drop
from around 37% to 16.9% in the next 15 years.
Vietnam
must balance water needs between the utilities and agricultural sectors,
according to Jacques de Beer, a project manager with consulting and
engineering multinational Poyry.
"Balancing
water resources has become more complex as a result of climate change,"
De Beer told OBG. "There's an aim to shift away from hydropower due to
the difficulties of managing unpredictable water levels for power
generation."
Indeed,
reduced rainfall triggered by the El Nido weather pattern is expected to
impact water levels at Vietnam's hydropower plants through to the end of the
year, with operations at several facilities temporarily halted.
Broadening
the role of natural gas
As Vietnam
scales up its manufacturing sector, natural gas could play an important role
in satisfying the country's energy needs, while also serving an industrial
use.
The country
has sizeable natural gas resources – with 700bn standard cu metres of proven
reserves as of the end of 2015, according to figures from the US Energy
Information Administration. However, most of the country's deposits are
located offshore and up to 50% have high carbon dioxide content, which adds
to operational costs.
Imported
feedstock, to be landed at two liquefied natural gas terminals slated for
completion in 2020, should help bridge the shortfall in the medium term,
though hydrocarbons' share of Vietnam's overall energy mix is slated to
decline from 25% to 13% by 2030.
"While
the revised PDP 7 shifts some coal-fired power plants to natural gas, from a
strategic standpoint Vietnam intends to use more gas to produce
petrochemicals, with the ambition of becoming a refining and petrochemical
hub in South-east Asia," Nguyen Anh Duc, general director of the Vietnam
Petroleum Institute, told OBG.
