Introduction Shell Energy and Chemicals Park Rotterdam
Electrical Infrastructure & Equipment
◼ One of the largest petrochemicals sites in Europe with over 550 hectares
◼ Shell Pernis has an own distribution grid and generators:
◼ Substations: ~100 HV (66kV to 3kV) and LV;
◼ Load Pernis: ~200MW (~500.000 households);
◼ Generation Pernis: 180MW by 9 generators (steam- and gas-turbine driven).
◼ The system provides electrical power to the plant installations, e.g.:
◼ 6.000 LV motors, 700 HV motors;
◼ 2.100 LV switchboards, 120 HV switchboards;
◼ One of Main Challenges:
◼ There is a large and complex project scope to replace aged equipment (e.g. oldest switchboard from
1947, 70 years old)

Complex puzzle
◼ The energy transition is a complex puzzle this impacts not only the electrical system but also other utilities
on site like steam, compressed air, fuel gas and natural gas.
◼ Overall trends are:
◼ Increase in electrical load due to electrification, the addition of new plants and processes such as CCS
and E-boilers.
◼ Reduction in steam demand by energy efficiency improvement and network optimization, replacement
of turbine driven compressors and shutdown of old plants.
◼ Inputs for this puzzle are interdependent and not easy to plan, for example:
◼ Shut down of units depends on remaining lifetime and marked demand for products.
◼ A gas turbine driven generator fed with fuel gas can only be switched of when less fuel gas is
produced, the steam demand is reduced and an alternative source of electricity is in place.
◼ Therefore flexibility and quick project execution are key.

Impact on electrical infrastructure
◼ Step size increase of power consumption which was not anticipated in the original design and stretches
an already congested electrical network beyond it’s original design limits.
◼ Shift from redundancy N+1+G to a more risk based approach which requires a change in mentality and
operation of the network.
◼ The expansion of the internal network and an increased electricity demand from the grid are part of all
scenario’s. Exact implementation schedule is not clear so the design needs to be as flexible as possible.

Cooperation
◼ Accommodation of an multiple times higher electrical power demand in de coming years requires open
discussion between customer and grid company for example on redundancy.
◼ Exact phasing and execution of the roadmap for the energy transition depends on large number of
parameters, therefore alignment between all stakeholders in all stages of the transition is key for success.
◼ Future sources of electricity will have a more intermitted character, also the electrification of plants will
cause more fluctuation of the electrical energy demand of a site, this can ether be a risk or a chance
depending on how it is handled.
◼ Electric heaters and drives can be switch on/off faster and can be controlled more easily than
conventional gas fired heaters and turbine driven equipment. This increases the possibilities of demand
management but requires changes in the operational philosophy and design of the plants.
