Aberdeen Standard Investments’ (ASI) maiden economic infrastructure fund has made its final investment with the acquisition of bulk liquid storage firm Oikos Storage.

SL Capital Infrastructure I (SLCI I) has bought the storage terminal owner from Challenger Life Company for an undisclosed sum.

Oikos is the only independent operator of liquid bulk storage terminal located on the River Thames Estuary, offering 300,000 cubic metres of tank storage capacity.

The company currently handles jet fuel and diesel and is critical infrastructure for the supply of jet fuel to London Heathrow, Gatwick and Stansted airports and diesel to the South East and Midlands of the UK.

Dominic Helmsley, head of economic infrastructure at Aberdeen Standard Investments, said: “We consider Oikos as a key strategic partner for its customers, offering emission efficient infrastructure for the import and onward distribution of its stored product through having unique access to pipeline connections and a newly developed deep-water jetty.

“We value the development undertaken by the company’s current owner, which has resulted in a highly modern facility and have been impressed by the existing management team’s level of commercial capability and look forward to working closely with them to achieve the business’ strategic goals and continue developing the asset to enhance the service proposition to its customers.”

ASI said the transaction represents the eighth and final investment in its SLCI I fund, which is focused on investing in core infrastructure assets in Europe.

SLCI I’s other investments comprise hydro-electric plants in Norway, a gas distribution business in Finland, a natural gas transportation and processing system in the Netherlands and new trains across the UK.
