Nature and extent of works:
Installation Solar PV carports across Adur & Worthing car park estate, supply PV to generate an approximate range of 18 kW min to 250 kW max. of electricity across 6 no. sites. Installation at 1 of the 6 sites above to include 1 battery storage facility to capture and store the electricity produced by the PV, approximate size of battery energy storage system 300 kW/h min. We would also be looking to install 13 no. EV chargers (7 no. fast charger 22 kW, 6 no. rapid charger 50 kw) that would be distributed throughout the 6 sites. The metering arrangements for each technology need to be carefully considered to ensure that energy from all three technologies is captured at source. The contract would also include for operation and management and maintenance for the duration of the contract. The provider is to manage the design and build (including obtaining planning permission), installation and maintenance of the above for the duration of the contact.
Nature and quantity or value of supplies:
The goods installed would need to meet the energy demand over the duration of the contact.
The provider should allow for an estimate of replacement parts in order to maintain effective energy production for the duration of the contact, to be stated within your proposal (minimum performance guarantee likely to be included within any tender).
The EV chargers will need to meet the performance requirements of the West Sussex County Council (WSCC) EV strategy (further detail can be provided).
All products to be certified for commercial operation on publicly accessible sites.
Nature and extent of services — description of the agreement Council anticipates to set up with the economic provider:
The installation above would be paid for by the provider/tenderer on the basis that they would then enter into an agreement with AWC who would buy the energy produced from the sites for the duration of the contact at a price below the standard market rates (no cost to the Council this would be based on a PPA model).
The EV chargers would also be paid for by the provider/tenderer (no cost to the Council) the provider is then to setup an operating model that they can charge the end user directly for the electricity they use to charge their vehicle. The EV chargers would also look to utilise the energy generated by the PV Carports and this would then be offset by the provider charging the customer direct for the EV charge (based on the WSCC EV strategy setup).
The Battery Energy Storage System primary role is to feed the EV chargers with excess solar generated electricity and dynamically manage any grid constraints; the battery will be capable of providing grid services including frequency response. This would also be paid for by the provider/tenderer (no cost to the Council).
The above arrangement would last for a maximum of 25 years (subject to the providers business case) and during this time the ownership of the equipment would sit with the provider until the end the contract term when all equipment would revert to the freeholders. All the installations need to feed into a Virtual Power Plant via a commercial aggregator of the providers choosing. As far as already known, anticipated time-frame for delivery or provision of products:
— contract/lease in place with Adur & Worthing Councils — October 2020,
— site surveys analysis and planning — October-December 2020,
— fabrication – January-March 2021,
— installation – April-June 2021.
