The challenge in transition from coal-fired power to renewable energy

Renewable energy - great potential but still indifficulty

 

According to the report of theMinistry of Industry and Trade, in the past 15 years, the growth of commercialelectricity has been continuously increasing, it is expected to continue toincrease rapidly in the coming time. Demand of electricity also grew at a rateof 13% in the 2006-2010 period and it increased 11% in the last five years. Itis expected that at least in the next 10 years, electricity demand will grow byless than 10%. Specifically, in 2015, total of energy consumption nationwidewas about 55 million tons of oil converted (TOE). Vietnam's national energydevelopment strategy to 2020 with a vision to 2050 also aims to ensuresufficiency of energy for socio-economic development with specific output up to2020, demand of energy will be around 100-110 million TOE and 310-320 millionTOE by 2030.

Vietnam is in the early stages of the transition from using fossil fuels tothe use of clean energy and renewable energy towards a low-carbon economy,friendly to environment. In order to facilitate the development of renewableenergy in the future, on April 11, 2017, the Prime Minister signed Decision No.11/2017/QD-TTg on mechanisms for encouraging the development of projects ofsolar energy in Vietnam. It specifies the purchase price for all electricityproduced from solar power plants connected to the grid is 2,086 VND / kWh(excluding value added tax). This is considered one of the most anticipateddecisions for the development of solar energy in Vietnam since there has notbeen a single pricing mechanism for solar electricity. Energy policy makers arehoping for the "boom" of solar power projects, first of all inpotentially good areas like the central coastal provinces. In particular, thedevelopment of solar energy will facilitate the development of a range ofrenewable energy sources in the coming time such as wind power, biomasselectricity.

 

However, according to experts, the investment inrenewable energy is not easy, especially the high rate of investment makesprice of electricity high. At present, when solar energy accounts for only asmall proportion of total electricity production, this factor does notsignificantly affect electricity prices. But in the long run, this will have acertain impact on electricity prices.

 

What is the direction for the coal-fired powerindustry?

 

According to Electricitydevelopment Plan to 2030, it is expected that by 2020, the total power output of coalwill be around 26,000 MW, producing 131 billion kWh of electricity, accountingfor 49.3% of the electricity produced and consuming about 63 million tons ofcoal. By 2030, the total capacity of coal-fired power plants will be about55,300 MW, producing about 304 billion kWh, accounting for 53.2% of theelectricity produced, consuming about 129 million tons of coal. Although theplan has revised up the rate of clean and renewable energy sources, coal-firedpower plants still account for a large share of the power structure, this is themain solution for ensuring national energy security in the long-term.

To ensure energy security, our country is shifting from country ofexporting energy to importing energy. In the past, our country exported energyand electricity to Cambodia, Laos, and exporting coal with the most quantity ofup to 20 million tons per year. However, since 2016, our country has importednearly 10 million tons of coal and bought electricity from China. Expertspredict that by 2020, the country will have to import about 20 million tons of coal;and it will increase much more in the following years.

Looking at the above figures, Vietnam is facing major challenges in termsof rising energy demand, while environmental constraints are becomingincreasingly tight. This, on the one hand, puts pressure on ensuring energysecurity, on the other hand, it puts pressure on the economy to mobilize enoughcapital to invest in the energy sector. In the context of electricity fromhydroelectricity that has exploited its potential, nuclear power has stoppedinvesting ... coal power is still an important source of electricity for thecountry in the next 10-20 years. Experts share the view that the issue is notwhether to develop coal-fired thermal power but how to develop coal-firedthermal power both to meet energy needs and not to destroy the environment.Analysis of this issue, Associate Professor, Dr. Tran Dinh Thien, Director ofVietnam Institute of Economics said that many opinions are concerned about coalthermal power has bad impact on the environment but in the context of thecurrent economy, development of coal-fired power is "mandatory" Theimportant issue is that what kind of technology is used in coal-fired powerplants. To do this, the State needs to have mechanisms to encourage enterprisesto invest in modern technology with attractive price policy.

At present, the Government has strategies to adjust electricity prices inorder to pay attention to the demand of production and consumption of thepeople; On the other hand, the government adjusts electricity prices toencourage investment in energy supplies, especially renewable energy sources inthe coming time. According to experts, it is time to clarify what is the priceof electricity serving the common good, what is the price for doing business inthe market. With such a clear strategy, energy prices in general, electricityprices in particular that will keep up with the market and the internationallevel, is feasible in the early time.

According to statistics, currently in Vietnam, there has 20 coal-firedpower plants in operation with a total installed capacity of about 13,110 MW.All the thermal power plants under construction and in operation have the EnvironmentalImpact Assessment Report appraised and approved by the Ministry of NaturalResources and Environment. Among these, EVN's coal-fired power plants have beendesigned to treat waste gas, waste water and solid waste according toregulations. Specifically, regarding the treatment of exhaust gases, the newprojects put into operation and are under construction will be equipped withenvironmental treatment systems to meet the current regulations. Existingcoal-fired power plants, EVN has carried out a review and set up a plan forupgrading the exhaust gas treatment system, which is expected to be completedin the period of 2018-2019. In addition, EVN's all of coal-fired power plantsare designed for construction of industrial wastewater treatment system to meetthe national technical standards for the environment. Centralized wastewater treatment systems areperiodically inspected to ensure design efficiency. For treatment of solidwaste, coal plants in the North and some coal plants in the South have contractedwith the units that they will handling the whole of ash. Sloughs are dividedinto plots for storage and installation of circular watering systems withautomatic sprinklers.

Ensuring the environment in coal-fired thermal powerprojects is a relatively difficult problem, a headache for managers. Analysisof this issue, Mr. Ngo Dong Hai, Deputy Head of Central Economic Affairs Committee,said that ensuring the environment when deploying thermal power plants must beplaced on the top. Experience from other countries in the world shows that, ifproper attention is given to technology and strategy at the beginning of theproject, coal-fired power plants will meet the requirements of adaptation ofclimate change and environmental protection. In the context of our country, iftoo focused on the development of coal thermal power will depend on the supplyof fuel. But without careful calculations, energy security is also a difficultproblem.

 

To solve the problem ofenergy security, Ngo Dong Hai also said that it is necessary to put energysaving issues on all forums. To solve the problem of saving must come from atleast two factors including technology and behavior. Especially in production,technological factors must be placed on the top. Energy saving must bemandatory and included in legal documents. Therefore,  it will not only ensures  the reduction of pressure on energy securityand it is also an opportunity for the economy to transform technology, accessto modern energy saving, environmentally friendly and ensuring sustainabledevelopment in the future.
