Liberalized Cost of Energy  LCOE

LCOE ($/kWh) is one of the most commonly used measure of cost of electricity for policy marker, research institutions and corporations that aim to derive long term investment
strategies. It is used to compare lifetime costs of electricity across technologies and countries.

LCOE is also a “break even” price that investors have to charge on electricity output in order to justify the investment by making the project NPV to be zero. Therefore by comparing wholesale electricity prices and LCOE it can be concluded whether a particular technology has reached grid parity or not.

Basic formula to calculate LCOE for any technology:

𝐿𝐶𝑂𝐸 = (𝑇𝑜𝑡𝑎𝑙 𝑙𝑖𝑓𝑒𝑡𝑖𝑚𝑒 𝑐𝑜𝑠𝑡 𝑜𝑓 𝑒𝑙𝑒𝑐𝑡𝑟𝑖𝑐𝑖𝑡𝑦 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛)/
                              (𝑇𝑜𝑡𝑎𝑙 𝑙𝑖𝑓𝑒𝑡𝑖𝑚𝑒 𝑒𝑛𝑒𝑟𝑔𝑦 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛)

The major components of lifetime cost of generating electricity from a power plant can be broken down into CAPEX, Operating and Maintenance (O&M) and fuel costs. Depending on the purpose of study, technology under focus and regulatory regime of projects, other costs such as interests, tax, salvage value, carbon emission costs etc could also be included in the calculation of LCOE.

The IEA and OECD used the following formula for LCOE in their cost projection:

LCOE = P.Electricity = ∑t((Investmentt + O&Mt + Fuelt + Carbont + Decommissioningt)*(1+r)^t)
/ (∑t(Electricityt*(1+r)^t))

Where Electricityt: The amount of electricity produced in year “t”;
P.Electricity: The constant price of electricity;
(1+r)^t: The discount factor for year “t”;
Investmentt: Investment costs in year “t”;
O&Mt: Operations and maintenance costs in year “t”;
Fuelt: Fuel costs in year “t”;
Carbont: Carbon costs in year “t”;
Decommissioningt: Decommissioning cost in year “t”.

Conclusion
As part of the broader project commissioned by Statkraft, this particular study is important because China is going to be the price setting country for all five technologies studies except CCGT in future.

China is already supplying the majority of solar PV panels in the global market today. It also deploys the most solar PV projects annually and it is expected to do so in the coming decades.

China is also installing the largest number of wind projects in the world. With its massive excess capacity, continued innovation and quality improvement, it is expected to export more and more onshore wind turbines. 
Given its impressive dominance of solar PV panels in just limited time, there is a very high chance that China will dominate the world’s wind turbine market as well due to its cost competiveness.

Gas fired power technology is expected to remain as a marginal power generation technology in China due to higher LNG prices and therefore higher LCOE. Most of the planned CCGT plants will be deployed in the east part of China to replace coal fired power plants to reduce air pollution. Therefore most gas fired plants will be combined heat and gas plants that will be deployed in the northeast of China.

China is already exporting advanced coal fired technology and equipment to many countries.

Given its massive scale of future deployment and the fact that China has developed advanced coal technology with its own intellectual property at much lower costs, China is expected to dominate world’s coal fired technology in the decades to come.

Nuclear and high speed train are the two pillars of Chinese high end machinery export that is being one of the highest priority for the state. China has the largest pipeline of nuclear power plants in construction and it has developed its own nuclear technology. With the engineering experience, human capital and financing from Chinese banks, China will export and be the dominant player in the global nuclear market as well.

Modelling results show that coal will continue to be the cheapest form of generation up to 2035 without taking into consideration of carbon prices. Nuclear is the second cheapest for of energy right now, but is expected to be surpassed by onshore wind very soon. Solar PV will see the largest decline of cost approaching 2035, though it will still be higher than that of wind, nuclear
and coal. CCGT will be the most expensive form of energy in 2035, largely due to higher capital costs and higher LNG prices in Asia.

The results are in line with most other studies, though the predicted range is usually quite wide in these studies. They are also in line with current Chinese energy policies. China is promoting cheap renewables such as wind and solar in an unprecedented scale. However, it is still developing advanced coal fired power technology and nuclear to meet future energy demand and reduce carbon emissions. However, it does not have an ambitious plan to build more gas
fired power plants due to its much higher costs of energy.

Due to limitations of the model, inputs, accuracy of data etc, the modeling results should not be treated as an exact prediction of future cost development trajectory. Instead the overall trend is more important than the exact numbers.
Given the limitations, further research opportunities lie in the more comprehensive treatment of modelling assumptions and inputs. For instance, the static assumptions of capacity factor, WACC, learning rates, global and local contents etc could all vary as time passes.

Other cost items such as taxes, depreciation, subsidies etc could also be factored into the model to derive a more realistic cost prediction of these power generation technologies.
