Advice Notes on Hydro Technology Economics for the NPA Region

Hydro

The Advice Notes aim to provide introductory material for entrepreneurs, startups and SME’s, considering to enter into the renewable energy sphere and based in the NPA regions partners to GREBE. The scope of the Advice Note covers regional, trade and industry, renewable energy (RE), technology information from Ireland, Northern Ireland, Scotland, Iceland and Finland. Different partner regions have different level of deployment of the various RE technologies covered by the Advice Notes. Thus, the level of information will vary depending on the level of deployment for each technology. For example, wind is not deployed on a large scale in North Karelia (Finland); however, it is widely deployed in Scotland, Ireland and Northern Ireland.

Full details are available on the GREBE website:

The focus of the Advice Notes is on regional information of some of the main economic characteristics sited as imperative, when making an informed choice, regarding which RE technology may be the optimal choice for a new business venture:

  • Costs and economics associated with the relevant technology
  • Support schemes available, relevant to the technology
  • Government allowance/exemptions, relevant to the technology
  • Funding available for capital costs of the relevant technology
  • List of the relevant to the technology suppliers/developers, with focus on local/regional, suppliers/developers and the products and services they offer.

Hydro2

Hydropower is of the most reliable and cost-effective methods to generate electricity, as it can immediately respond to variations in electricity demand meeting both base-load and peak-load demand. The key advantage is that hydro power provides a steady and secure source of electricity supply. Furthermore, it very highly efficient (from 70 to 90%), has a long life span and attractive energy pay-back ratio. Other benefits of hydro are that it is a largely predictable resource of renewable energy (the annual generation can be predicted using historical rainfall data/catchment flow data).When considering the payback period for SHP, account should be taken of the lifespan of the system.

A general SHP project cost level is very difficult to predict as they are very project specific contingent on the local surroundings, hydro-technical constructions, turbines and electrical equipment. Small-scale hydropower uses water flowing through a turbine to drive a generator that produces electricity. The amount of a hydropower installation’s potential power output (kW) is directly related to two key variables:

Head – The vertical distance between the water level at the intake point and where the water passes through the turbine. Hydro projects can be categorized into three categories according to the existing head.

  • Low head – up to 10m
  • Medium head – 10m to 50m
  • High head – greater than 50m.

Flow rate – the volume of water flowing through the turbine per second, measured in litres/second (l/s), or cubic metres/second (m3 /s).

Ireland to test floating offshore wind concepts in Galway Bay

Galway Bay

The Irish government has confirmed that permission has been granted to use a site in Galway Bay to test marine renewable energy, including floating offshore wind. Ireland’s Minister of State at the Department of Housing, Planning and Local Government, Damien English said Ireland’s Marine Institute has been awarded a foreshore lease for the Galway Bay Marine and Renewable Energy Test Site.

The test site, located 1.5 km off the coast of An Spidéal, will allow for the deployment and testing of a range of prototype marine renewable energy devices, innovative marine technologies and novel sensors. The facility will also provide access to the SmartBay observatory allowing researchers and scientists to conduct research in the marine environment. The Marine Institute had operated a test site at the same location for 11 years until March 2017, generating a significant research knowledge base. The test site will provide researchers and those involved in developing ocean energy devices with an area in which to test and demonstrate quarter-scale prototype ocean energy converters and related technologies.

A maximum of three marine renewable energy test devices will be deployed at the test site at any time and will only be deployed for a maximum duration of 18 months, with the exception of any floating wind device which may only be deployed for a maximum of 12 months. The lease has been granted on the basis that there is no provision to export power from the test site to the National Grid. The Galway Bay test site will operate for up to 35 years, with devices on site intermittently throughout the year. Under the terms of the lease, the Marine Institute will produce an environmental monitoring plan for the test site, and make all the findings of the monitoring programme available to the public.

Water-Energy Nexus Workshop – Wednesday 7th September 2016

Water-Energy Nexus

The Centre of Sustainable Technologies based at the University of Ulster is an inter-disciplinary research centre, challenging many aspects of sustainability associated with the built environment. Their remit is to undertake ground-breaking activities in a range of areas including architecture, building energy efficiency, clean combustion, construction, highways engineering, sustainability, renewable energy and river hydraulics. Recognising that these areas are of the utmost importance to a rapidly changing built environment reacting to climate change, they cite that their dominant research activity in terms of income and activity is energy.

The centre is hosting an event addressing the Water-Energy Nexus, looking at the challenges faced by the inextricable connection between water requirements and energy resources.  Taking place at the University of Ulster, Jordanstown Campus, the half day event has input from a range of leading experts in the field.
