CLIENT

Situation.

A large-scale production facility in Ras Al Khaimah operated 24/7 with its entire electricity demand covered by the regional distribution grid (33kV, 10 MVA connection). Annual consumption exceeded 35 GWh, with load levels between 3–5 MW. With flat, unused rooftops and adjacent land available, the client’s ambition was to integrate photovoltaics (PV) and move toward 100% local energy coverage to stabilize costs and secure long-term competitiveness.

OUR

Approach.

Ras Al Khaimah’s excellent solar conditions made PV a logical first step. However, with continuous 24/7 operation, PV alone could only supply up to 30% of consumption during daytime. To achieve full coverage, the solution had to combine:

• Large-scale photovoltaics (roof + ground-mounted)

• Battery Energy Storage System (BESS) for short-term balancing and backup

• Distribution grid optimization to manage clipped energy and seasonal variability

The requirement was clear: ensure stable energy supply entirely from local renewable sources

OUR

Solution.

Volthein designed a hybrid power plant that integrates rooftop PV, ground-mounted PV, and a BESS into one seamless system.
