GPP Big Field LLP (“GPP”) was the Employer to 5 Engineering, Procurement and Construction contracts (“EPC contracts”) to build solar plants in the UK. The Contractor, Prosolia UK Ltd, is currently insolvent and therefore GPP sued its parent company, Solar EPC Solutions SL (“Solar”) as guarantor in order to recover both liquidated damages (“LDs”) and unliquidated damages for aspects of the Works which were late or non-completed.
