Framtida Flexpotential Greenfield Lysekil (LEVA, 2026)

Framtida flexpotential i industriell megaetablering — Greenfield Lysekil. A 17-page potential study (“potentialbeskrivning”) by LEVA i Lysekil on how future industrial establishments can be handled more sustainably and resource-efficiently through flexibility in electricity use and grid utilisation, with the planned industrial area at Brofjorden outside Lysekil as the focus. It models a fictional Preem Tech Park (PTP) because work on the real park has been paused. The web article that summarises it is Source - Energikontor Vast Preem Tech Park Lysekil (web).

Summary

New industrial establishments often add power demand that stacks up and risks over-dimensioned, sub-optimised grids. The report describes conceptual solutions for how flexible business and operating arrangements, such as dynamic power allocation and conditional agreements (villkorade avtal), could use existing infrastructure better and allow more establishments. The area is intended to become a climate-positive circular industrial park where one actor’s residual product becomes another’s resource. Preem AB, Preem Technology AB (owners of the area) and LEVA i Lysekil AB signed a letter of intent (avsiktsförklaring) on 18 January 2023 to investigate developing an area near Brofjorden into a climate-positive circular industrial park.

Fictional PTP. Work on the real Preem Tech Park has been paused “av anledningar som ligger utanför projektarbetets påverkan”, so a fictional PTP was created and the description rests on it. The report says the figures are assumptions based on dialogue with business actors and LEVA’s internal resources, that it is a very rough simplification meant to see whether the flexibility approach has potential, and that it assumes energy can be bought and sold.

System modelled. The Stångenäs system is treated as one internal network without bottlenecks, connected through two 130 kV lines from Trollhättan, with three loads: Preem (assumed constant and inflexible at 70 MW, 550 GWh/year, somewhat below 70 MW × 8,760 h because planned and unplanned outages are expected), LEVA’s grid (homes, holiday homes, public sector, other industry; 34 MW in winter and 15 MW in summer, 160 GWh/year, load growth 2%/year per the network development plan, with peak load assumed to be flattened by price signals and power tariffs) and the added PTP.

Key figures

The fictional PTP (available area 240,000 m², 60% buildable) consists of a tropical fish farm, a salmon farm cooled with waste heat, a greenhouse, a slaughterhouse, a common water-treatment plant and electric-truck charging. Maximum winter power, flexibility, endurance and yearly energy per component (summer values are identical):

The greenhouse flexibility rests on a large LED lighting load that can be ramped up and down quickly; the report notes plants want at least 7 hours of “rest” per day. Fish farms are described as having some flexibility through pumping, filtering and oxygenation and through temperature regulation with stored waste heat. Average power for the PTP is about 12 MW.

Local generation assumed for 2027:

• Solar: about 31.5 MWp and 29 GWh/year (existing solar with growth 8 MWp and 6 GWh; Lyse solar park 4.5 MWp and 6 GWh; PTP rooftops 14 MWp and 10 GWh; ground-mounted near PTP 5 MWp and 7 GWh). Existing municipal solar in 2023 was almost 4 GWh and almost 5 MWp.
• Wind: about 23 MWp and 62 GWh/year by 2027 for the area, per the report’s own approximate (“direkt” in scare quotes) tally: five turbines genuinely close to Preem Tech Park — two existing Lysekils Energi Vind AB turbines (3 MW each, about 11 GWh together), a planned replacement turbine of a little over 4 MW and about 14 GWh (swapping out two older ones), and two further turbines judged plausible (each ~4 MW/~14 GWh) — plus six further, smaller and older turbines elsewhere in the municipality contributing about 5 MW/9 GWh, folded into the same total rather than added on top of it. The report’s permitting strategy keeps to a 150 m building height and at most six turbines in the PTP area itself.

System result (existing loads, generation and PTP):

Flexibility after PTP is −8.5 MW with an endurance of 265.6 minutes (as printed).

Key claims

1. Average power rises by only about 1 MW before and after the park. The report calls this a basic prerequisite for the system possibly managing without extensive grid build-out, with flexibility and storage capabilities developed locally instead.
2. Connecting all the local production to LEVA’s existing grid is difficult without relatively extensive storage or a guarantee that production reaches a system with reasonably secured consumption, or that production can be curtailed.
3. Flexibility in the existing loads would also have been very useful for the system, which they may gain through price signals and power tariffs. The results can indicate how large an energy store (power and energy) the area may need, and such stores can likely serve purposes beyond shaving power peaks.
4. Redundancy is an open question. The report asks whether the system must always have full redundancy and whether it can be accepted that full redundancy statically lapses for a few hours a year. It expects such hours to occur only when several conditions coincide: one 130 kV line out of operation, very cold, December–February, calm, and weekday 07–11 or 16–19.

Limitations and further work (stated by the report)

• The capacity of existing lines and how much of the PTP fits in the existing grid must still be investigated or assumed.
• The probability of how often and how much the flexibility capabilities need to be used must be studied.
• The system has power limits but surplus waste heat as a resource; the study is a fictional case and assumes energy can be bought and sold.
• The report does not describe any legal or market mechanism for procuring the flexibility, and it names dynamic power allocation and conditional agreements only as approaches.
