SWITZERLAND''S ENERGY TRANSITION PLAN KEY STRATEGIES FOR 2050

New Energy Storage Plan
The “Special Action Plan for Large-Scale Construction of New Energy Storage (2025-2027)” released by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) outlines a roadmap to scale up energy storage to support the country’s rapidly expanding renewable energy capacity.

The key to flywheel energy storage is
Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th. The flywheel is designed to rotate at high speed, and when electricity is supplied to the motor, the flywheel starts to spin, storing kinetic energy. The energy stored in the flywheel is converted back to electrical energy by the generator when required. [pdf]FAQS about The key to flywheel energy storage is
How does Flywheel energy storage work?
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
What is the difference between a flywheel and a battery storage system?
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
Why do flywheel energy storage systems have a high speed?
There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
What is a flywheel/kinetic energy storage system (fess)?
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
How long does a flywheel energy storage system last?
Flywheel energy storage systems have a long working life if periodically maintained (>25 years). The cycle numbers of flywheel energy storage systems are very high (>100,000). In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety.
Are flywheel energy storage systems sustainable?
With proper maintenance, flywheels can operate for over two decades, making them a more sustainable option than batteries. However, flywheel energy storage systems also have some disadvantages. One of the main challenges of flywheel systems is friction loss, which can cause energy loss and reduce efficiency.

Armenia Photovoltaic Energy Storage Investment Plan
The government aims to add 1,500 MW of new capacity from solar and wind energy, with an estimated construction cost of around $1.2 billion. This initiative is part of Armenia’s broader efforts to enhance its energy independence and reduce reliance on imported fossil fuels.

Does Armenia have solar energy?
Armenia has significant solar energy potential: average annual solar energy flow per square metre of horizontal surface is 1 720 kWh (the European average is 1 000 kWh), and one-quarter of the country’s territory is endowed with solar energy resources of 1 850 kWh/m 2 per year. Solar thermal energy is therefore developing rapidly in Armenia.
What percentage of Armenia's Energy is renewable?
Renewable energy resources, including hydro, represented 7.1% of Armenia’s energy mix in 2020. Almost one-third of the country’s electricity generation (30% in 2021) came from renewable sources. Forming the foundation of Armenia’s renewable energy system as of 6 January 2022 were 189 small, private HPPs (under 30 MW), mostly constructed since 2007.
Can bioethanol production be exploited in Armenia?
Annual biogas potential of around 135 mcm is just beginning to be exploited, and the Renewable Energy and Energy Efficiency Fund recently produced an Assessment of Bioethanol Production, Potential Utilization and Perspectives in Armenia exploring possibilities for bioethanol production and presenting the concept to investors.
How much does it cost to rebuild a HPP in Armenia?
Various upgrades have been performed since the early 2000s, and one of the seven HPPs (Yerevan HPP) is currently under reconstruction at a cost of USD 40 million. Constructing small HPPs is Armenia’s favoured course of action to develop the renewable energy sector and secure energy independence.
How many HPPs are there in Armenia?
Forming the foundation of Armenia’s renewable energy system as of 6 January 2022 were 189 small, private HPPs (under 30 MW), mostly constructed since 2007. Installed capacity is approximately 389 MW for annual generation of 943 GWh, covering 14% of domestic supply.
What is the procedure for energy audits in Armenia?
The Procedure for Energy Audits is the norm-setting legal act that regulates energy audits in Armenia. This procedure was approved by Government Decree 1399-N of 31 August 2006 and revised by Decree 1105-N of 4 August 2011 and Decree 1026-N of 10 September 2015.
