- 1. “Adapting to the UK energy market as a responsible & reliable large electricity user” Ben Burggraaf – Energy Operations Manager
- 2. Water & waste water service provider —Supply 3 million people (~1 million households) —A “not for profit” utility company – All gains go to benefit customers – Reducing bills – Providing social tariffs – Accelerated investment “Earn the trust of our customer, every day”
- 3. , The income we receive from 100,000 households does nothing other than pay for electricity
- 4. Energy management facts —Large energy user – 4,100 sites – 460 GWh’s per year —Green energy generator – 56 sites – 97 GWh’s per year – Multiple technologies • Hydro generation • Solar generation • Wind generation • Anaerobic digestion (gas to grid, CHP) kW capacity 501 + 101 - 500 0 - 50 51 - 100 Status Renewable Energy Generation Sites Strata Florida Llys y Fran Res Maerdy Crai Preseli WTW Llwyn-on Nash Swansea Cefn Dryscoed Eign Cardiff Afan Llanfoist Lliedi Ponsticill Penycefn Eithinfynydd Ffynon Lugwi Brenig Queensferry Kinmel Bay Usk Cilfynydd Glaslyn Cog Moors Talybont Dol y Mynach Bolton Hill Hydro – in delivery Hydro - Live Wind – planning/delivery Solar PV - Live Digestion CHP or AD - live Biomass heating – Live Hydro – in feasibility / design Solar PV – planning / delivery Elan Valley Builth Wells CarnoHirwaun Nantybwch Glascoed Llangefni Gaerwen Dolbenmaen Alaw Court Farm Wentwood Sluvad Ponthir Bontgoch Llanina Alwen Mynydd Llandegai Penthir Res Llyn Celyn Cwmorthin Ffestiniog Claerwen River Llyn Brianne Cowlyd Five Fords Memorial Wind – in feasibility / design Ty Awen Tyn y Waun 28/04/16 Biomethane to grid - Live Felindre Cwmtillery Wind – Live

- 7. Current activities — Generate more – Increasing output to 140 GWh’s per year — Continue to use less – Invest in energy efficient equipment – Behavioural efficiency program — Demand management – Avoid TRIAD’s & peak tariff periods – Roll out of frequency response technology – Participating in DSBR and Demand Turn Up — Flexible electricity supply contract – Resilient to government policy changes – Transparent 3rd party charges Ynni
- 8. Employee Engagement – three simple actions: “if we all save a little, no-one has to save a lot” Switch of your computer when you finish work Buy energy efficient, when replacing equipment Consume less especially 16:00 – 19:30
- 9. Our future plans beyond 2020 —Generate even more – Increase resilience – Move towards self-sufficiency in power —Continue to use less – Invest in energy efficient equipment – Build energy efficiency into everything we do —Storing energy – Roll out of battery technology —Active demand management – Minimise costs at peak UK demands – Maximising revenue from curtailable demand Ynni
- 10. Conclusion Final thought —The UK electricity market is changing rapidly —To control energy costs we need to: – Realise that the market is changing rapidly – Create an integrated approach – Start actively participating in the market – Have a flexible supply contract – Act as a responsible & reliably consumer to ensure that our customers aren’t impacted by the changing market Trust
