Hydro Electricity Plant Tender

Greenfield Brownfield Greenfield Scope of WorkTo Build Large Hydro-Electricity Plant in the Silvermines mountains in North Tipperary.DescriptionA proposal to build a large hydro-electricity plant in the Silvermines mountains in North Tipperary has received a significant boost after it was included in a strategic plan to develop Europes electricity grid over the next decade.The 650 million energy storage project is the only electricity generating plant planned for Ireland included in the European Network of Transmission Systems Operators for Electricity ENTSOE plan for 2018 to 2028.The plant would be one of the largest private infrastructure projects in the history of the State and generate 360 megawatts of electricity.A cost-benefit analysis conducted by ENTSOE has confirmed the benefits to Ireland from the project. It has the capacity to generate electricity for 200000 homes and be worth 80 million a year in economic dividend.This will be achieved through a reduction in carbon emissions more efficient integration of renewable energy and the cost of electricity production.Environmental assessments to underpin the planning application have commenced with a formal planning process set to start in the latter half of next year.Work on the project would commence in 2022 subject to planning with a four-year construction phase. The pump-storage facility is set to displace electricity generated from fossil fuels at some of the countrys high-carbon emitting plants.And it will help balance the national grid by ensuring a brand new and completely green electricity supply source to cover outages and electricity demand spikes.The storage-based technology uses water from a higher elevation reservoir to flow through giant turbines generating electricity in the process before being collected in a lower reservoir.Water is then pumped from the lower reservoir to the higher reservoir during low-electricity demand periods. The lower reservoir already exists at the site by way of an open-cast mine flooded to a depth of some 70 metres at the foot of Silvermines mountains.The upper reservoir which will have be excavated in the side of the mountain will have to hold the same amount of water as the lower reservoir roughly 2.4 million cubic metres. Material excavated in the building process can be used to bank the sides of this part of the facility.
