Siemens’ control. These are subject to a number of risks, uncertainties and

factors, including, but not limited to those described in disclosures, in particular in

the chapter Risks in the Annual Report.

Should one or more of these risks or uncertainties materialize, or should

underlying expectations not occur or assumptions prove incorrect, actual results,

performance or achievements of Siemens may (negatively or positively) vary

materially from those described explicitly or implicitly in the relevant forward-

Cyber Security Challenges & Needs

Energy SecurityKeeping Critical Infrastructure Safe & Secure

• Previously stand-alone assets are increasingly connected to the outside world, which

improves efficiency but may open the door to external attacks.

• Risk management is vital. Having credible policies for security, continuity and performance

auditing systems can make the difference between competitive edge

and competitive failure.

• Power assets are classified as national critical infrastructure, leading to tighter regulatory

scrutiny and rising compliance standards

• Power generation companies need to invest in high performing cyber security solutions to

survive and prosper in a more connected and competitive world.

Grid Stability Challenges & Needs

Energy SecurityConsequence of Renewables Growth Lead to Need for

Inverter Dominated Power System

• Remaining fossil units may be highly cycled and the energy flow in the transmission system

complex.

• At the same time, the stability of a converter dominated transmission system is challenging.

The frequency and voltage control as well as fault ride through capability can require

installation of new additional equipment for stable and safe grid operation.

• Need for reactive power compensation

• Need for storage and flexible load peak units

• Increased demand on ancillary grid services and flexible dispatchable load

Availability & Reliability Challenges & Needs

Energy SecurityEnable secure operation range

• Many plants are expected to come online as required by market trading, so agility and

guaranteed availability are critical requirements.

• Securing availability, flexibility and profitability of power plants is an ongoing process and

specific to each facility. It can require new service products to appropriate address ever-

changing plant and market requirements

• A secure operation range is essential for operating with power plants in challenging

markets with an aging fleet it is essential to operate a power plant in a secure

operation range.

Renewables growth – impact on grid stability

Need for ancillary services

➢ Weak system with reduced short circuit power (Short Circuit Ratio decreased)

➢ Lack of physical inertia

➢ Need for reactive power compensation

➢ Need for storage and flexible load peak units

What is the hesitance to use synchronous rotating

equipment long term?

Back-up power & ancillary services✓ CO2 emissions

✓ Operational cost

✓ Maintenance effort

✓ Efficiency, operational

losses in kW

✓ Foot print, landscape

consumption

✓ Reliability & Safety

Rotating grid stabilization equipment is emission-free, even in a configuration

with a GT, if operated by synthetic fuel, e.g. hydrogen

Advanced state of the art rotating products are characterized by unstaffed

operation and very low supervision effort

Electrical synchronous machines, fly wheels are almost maintenance free

products with very long life time, unmanned operation , digital twin approach

Handicap due to rotational ventilation losses. Purposeful design can minimize

the impact. The handicap is questionable considering the excess energy

production periods by renewables

Size ratio significantly better compared to several inverter based configurations,

e.g. HV-DC link converters

Decades of experience with reliable and safe operation of rotating equipment

Rotating equipment provides the basis for reliable and safe system integration

of converter based units with commercial benefit
