The Danish Energy Agency launches improved LCoE calculator

Offshore wind is gaining competitiveness compare to conventional power options with a more than 30% decline levelized cost of energy (LCoE) compared to previous projections, shows updated LCoE calculator. The open source LCoE Calculator tool is available for energy planning and simulation in other countries. 

The LCoE Calculator is a tool to estimate and compare the socio-economic electricity production costs in a simplified manner using localized data and estimates.The improved calculator shows that the cost reduction in some of the core renewable energy options is bigger than previously expected by the Danish Energy Agency. Especially for offshore wind a combination of lower initial investment (CAPEX) and declining operational costs (OPEX) and technology improvement that allow new offshore wind projects to harvest more energy out of the wind at lower costs. This means that the levelized cost of energy for a Danish offshore wind project is expected to have fallen to EUR 46 per MWh excluding grid and system costs with production start in 2020. Compared to our previous assumptions CAPEX is expected to have gone down by close to 40%. Also improvement in operation and maintenance is expected to reduce OPEX by more than 20%. At the same time improvement in wind and power train design is expecting to increase the amount of full load hours of Danish offshore wind projects by 10% giving a capacity factor of more than 50%.

Onshore wind still cheapest Danish option

For onshore wind the expected average cost of producing one MWh for a wind project is now EUR 30 or almost 25% lower than previous estimate. Again low expected CAPEX (-20%) and 5% higher productions is the main drivers behind lower projected LCoE in Denmark. Compared to other technologies relevant for Denmark onshore wind is still the cheapest option for adding new capacity. As a densely populated country with a large initial fleet of onshore turbines area restrictions are limiting further expansion of onshore wind in Denmark. However repowering offers a good option to increase power generation from onshore wind which is also addressed in the new Danish energy agreement focusing on reducing the number of onshore wind turbines but increasing power output.

Solar PV is closing in

With an almost 40% lower LCoE than previous estimates solar PV is still gaining momentum driven primarily by more than 40% reduction in estimated CAPEX and further improvement of OPEX. Due to a limited amount of solar resources in the Northern part of Europe the capacity factor for solar PV is only 12%. That leaves large-scale solar PV with an estimated LCoE of EUR 40 per MWh for a Danish project.

Tenders to secure the lowest prices

With continuing falling generation costs for renewable energy sources the support schemes going forward is to a large extend based upon open and transparent tenders. This should ensure that the Danish consumers and industry will benefit from cost and technology improvements. With onshore wind and solar PV getting closer cost vise technology neutral tenders is planned again to ensure the lowest power prices combined with a sustainable and local power source.

About LCoE Calculator

The LCoE Calculator is a tool to estimate and compare the socio-economic electricity production costs in a simplified manner using localized data and estimates. The LCoE Calculator is based on internationally acknowledged methodology and permits comparison of different electricity production technologies based on nuclear, fossil or renewable energy as well as a number of high-potential energy efficiency technologies. The LCoE Calculator consists of an Excel based model and a manual discussing different aspects and data needed for socio-economic calculation of different power generation and energy efficiency options including possible data sources. The tool is designed for policymakers, energy regulators and planners.

The LCoE Calculator can be found on the Danish Energy Agency webpage.

Welcome to Danish Energy Agency!

The work of the Danish Energy Agency involves matters relating to energy supply and consumption, as well as Danish efforts to reduce carbon emissions. The Agency is also responsible for Danish building policy and promotes more sustainable building with regard to energy consumption, use of materials and economic issues.

The Agency is responsible for the entire chain of tasks linked to energy production and supply, transportation and consumption, including energy efficiency and savings as well as Danish national CO2 targets and initiatives to limit emissions of greenhouse gasses. The Agency supports building-policy initiatives to increase the productivity and quality of building as well as the operation and maintenance of buildings, with focus on sustainable building. The Agency also collaborates with the building sector to establish a good framework for the industry.

The Danish Energy Agency was established in 1976, and is an agency under the Ministry of Climate, Energy and Utilities.
