A first-ever Waste-to-Energy (WTE) project currently in the early stages of procurement and implementation at Barka in South Al Batinah Governorate could be potentially sized at 130-140 megawatts (MW) of capacity, up from the estimated 50 MW capacity presently envisaged by Oman Power & Water Procurement Company (OPWP) — the sole procurer of all new generation and water desalination capacity under the Sector Law. The higher capacity assessment has come from the Oman Environmental Services Holding Company (be’ah) — the Sultanate’s solid waste management flagship — which will supply municipal solid waste as feedstock for the Barka plant.
Be’ah is collaborating with OPWP, a member of Nama Group (formerly The Electricity Holding Company), in ensuring that the Waste-to-Energy project will receive a sustainable supply of raw material for the combustion process necessary to generate electricity.
“OPWP has completed the technical and economic assessment, and has managed to determine how much they are willing to subsidize the project one way or the other — or split the subsidy between us and the electricity sector,” said Fahad al Kharusi, Head of Business Development at be’ah. “Right now, the project is before the Authority for Electricity Regulation Oman for approval. Hopefully, if all goes smoothly, we will have the first tender for an Independent Power Project (related to a waste-to-energy scheme) by Q1 of 2019.”
Speaking at an industry forum on sustainable energy resources and technologies held in Muscat last week, Al Kharusi said studies conducted by the state-owned solid waste management entity envision an output ranging from 130-140 MW based on combustion technology. One tonne of municipal solid waste, he said, has the potential to generate about 600 kilowatt-hours of net electricity.
At the heart of the proposed Barka plant, he said, is an incinerator designed to consume 90 tonnes/hour of waste. Heat generated during the combustion process will be channelled to a boiler where water will be turned into steam, which will be used to run a turbine to produce electricity. Around 8-10 per cent of the plant’s output will be consumed by the plant itself for the incineration process.
An estimated 250-300 truckloads of waste will be supplied daily to the site, according to the official. The waste will be housed in a huge bunker enough to hold 7-10 days of feedstock. The waste will be suitably mixed to help achieve a homogeneous distribution in calorific terms. Flue gas will be processed through a series of filtration systems to produce carbon dioxide and water as end products.
Be’ah is also looking at other Energy-from-Waste (EfW) schemes to support a number of companies that depend on energy to run their operations, he added.
