An integrated site energy management plan is strongly advised amid South Africa’s power constraints, as it demonstrates opportunities – such as integrating electrical and thermal systems – to increase overall energy efficiency, says steam and boiler operations and maintenance service provider Associated Energy Services (AES). In terms of alternative energy solutions and the optimisation of manufacturing plants, “it’s all about preserving resources of production and any reduction in their use through efficient processes, operations or systems integration to lower production costs”, says AES commercial director Dennis Williams.
