Renew: Renewable Energy
Carbon Neutral Energy Supply
There are a number of electricity suppliers that offer energy generated from environmentally-friendly sources.
Purchasing renewable electricity helps reduce an organisation’s carbon footprint and can also demonstrate commitment to sustainability to customers and stakeholders.
Providers which include SmartestEnergy the largest purchaser of independent generation in the UK can provide business renewable energy at non-premium prices across a range of fixed and flexible contracts.
Typically suppliers can offer choice and transparency for their supply, selecting the proportion and mix of renewables – including wind, hydro and biomass – along with Good Quality CHP and conventional energy.
Workspace Technology encourages our customer to consider changing suppliers and sourcing Carbon Neutral electricity.
Site Generated Renewable Energy
Every kilowatt hour of renewable energy produced locally represents an equal reduction of power taken from the grid.
Feed In Tariff (FIT)
The UK Government have committed to decreasing our dependence on fossil and nuclear fuels and have legislated a Feed In Tariff, “FIT” sometimes called “Energy Cash backs”. This FIT obliges energy companies to pay a premium price to you, the energy generator, for all the energy produced by renewable system, whether it is consumed at the facility or exported back to the grid.
|Solar PV||≤4 kW new||21.0||25|
|Solar PV||≤4 kW retrofit||21.0||25|
|Solar PV||>10 – 50kW||15.2||25|
|Solar PV||>50 – 150kW||12.9||25|
|Solar PV||>150 – 250kW||12.9||25|
|Solar PV||>250kW – 5MW||8.9||25|
Power Usage Effectiveness PUE
It should be understood that under strict “Green Grid” rules for PUE calculation renewable energy (RE) is simply considered a contributor to the “Total Facility Power” and will not effect the PUE calculation. If however renewable energy is classified as an “efficiency measure” rather than an alternative source of energy then this figure can be deducted from the Total Facility Power, in turn this will reduce and therefore improve the facility PUE figure.
Solar photovoltaic (PV) panels convert sunlight directly into electricity that can be used for normal consumption. Each solar PV panel contains cells made of two or more thin layers of semi-conducting material, most commonly silicon. When a cell is exposed to light, electrical charges are generated and this is then fed into your home’s electricity supply.
Even on cloudy days, solar panels can capture solar rays and convert them into electricity. They do this silently and because they don’t emit any harmful pollution, they will increase green credentials.
The exact amount of potential PV energy will depend upon the available space to fit PV panels, orientation, surround buildings and environment.
40% of all the wind energy in Europe blows over the UK, making it an ideal country for turbines. Wind turbines use large blades to catch the wind. When the wind blows the blades are forced round, driving a turbine which generates electricity. The stronger the wind, the more electricity produced.
Intelligent Energy Management Module
With the continued increase in the costs of utility power it is becoming more important to consider the deployment of renewable energy technology.
Workspace Technology is one of the first Data Centre Design and Build specialists to introduce “Intelligent Energy Management Module” technology. This technology will, combine multiple power sources including utility, generator, PV (Photo Voltaic) and Wind Turbine to deliver a single “least cost“ power source. The Intelligent Energy Management Module least cost selection can be programmed for £kWhr, CO2 or both depending on client preferences.
Typically the primary power source will be PV, and Wind turbine delivered via inverter outputs. Wind and PV are variable and unpredictable power sources which at peak are only likely to contribute a modest percentage to the overall energy consumed by the data centre. The total percentage of renewable energy will depend upon the kW rating of the data centre verses the potential kW peak capacity of renewable. This will vary from facility to facility. The power demands of the data centre will therefore inevitably be supplemented with “utility” power which will vary depending on the available renewable power.
The Intelligent Energy Management Module will automatically start up generator power to top up renewable power sources should the utility power fail. Alternatively the generator could be run as a primary source if biomass fuel is used delivering reduced CO2 emissions.
