Lightsource bp is proposing to develop the West Mokoan Hybrid, a up to 390MW large-scale solar photovoltaic (PV) and approximately 300 MW Battery Energy Storage System (BESS) with up to four hours of storage duration. The project is made up of two separate sites, located on Benalla-Yarrawonga Road, Benalla, in the Hume Region of Victoria. The whole of the project area covers 770 hectares of land, which has been predominantly used for grazing.

The southern site, known as Kennedys Creek and the northern site, known as West Mokoan each received development approval from the Department of Environment, Land, Water and Planning (DELWP), now the Department of Transport and Planning (DTP) in November 2020 and 2022, respectively. Following minor changes to the concept design, the project has received a consolidated planning permit on 7 September 2026. This approval facilitates an increase in battery storage capacity and allows the two sites to be developed and operated as a single integrated project. The Project will be connected to the 220 kV Benalla Terminal Station (BNTS) and dispatching 300 MW at the Point of Connection. Proposed project components include:

• Approximately 596,932 solar photovoltaic (PV) panels (approximately 338,828 at West Mokoan and approximately 258,328 at Kennedys Creek) on a single-axis tracking system mounted on aluminium or steel piles

• Approximately 56 Power Conversion Systems (PCS) with two inverters per PCS (approximately 32 PCS at West Mokoan and approximately 24 at Kennedys Creek).

• Approximately 224 DC-Coupled BESS units (co-located with up to 56 of the PCS) connected to approximately 512 DCDC converters at West Mokoan and approximately 384 DCDC converters at Kennedys Creek

• DC and AC cabling for electrical reticulation

• A transmission line between Kennedys Creek and West Mokoan site parcels, connecting the Kennedy's Creek substation to the switching station located in the West Mokoan site area

• A step-up substation located within Kennedy's creek area, connecting the Kennedy's Creek portion of the site to the transmission line between the two site parcels

• A step up-substation and the 220 kV Benalla Terminal Station (BNTS) located within West Mokoan project area, to facilitate the connection of the combined Project into the wider electricity network

• Operations and Maintenance (O&M) facility area, control building, office and amenities

• Site access, internal all-weather access tracks and laydown areas

• Landscaping, native vegetation removal and revegetation

• Security fencing, Closed Circuit Television (CCTV) and Infra-Red lighting

• Business identification signage

• Realignment of easements.
