Energy Demand Management talk for Le Web3

An environmental riff -- where technology fits in Tom Raftery blog: tomrafteryit.net blog: synergymodule.com blog: cix.ie podcast: podleaders.com email: tom@tomrafteryit.net

Background • Social media? • Building a Data Centre • Cork Internet eXchange (CIX) • First in Ireland outside Dublin

Geek Porn!

Energy Efﬁciency?

Energy Efﬁciency? • Data Centre costs • Stafﬁng • Connectivity • Energy • => focus on energy

Energy efﬁcient DC Standard DC CIX 33% 12% Chiller 3% <1% Humidiﬁer 9% 4% CRAC 30% 80% IT Equipment 5% 0.01% PDU 18% <2% UPS 1% <1% Lighting 1% 1% Switch Gear

The Problem! • Wind energy de-stabilises • Grid infrastructure max’d • 2GW outstanding

Wind supply problems

3 Energy strategies • Build a hyper energy-efﬁcient DC • Network data centres • Energy Demand Management

DC Power Network • Network DC Power systems • Generate power by day, consume surplus power by night • Give control of network to TSO • TSO can now buy more wind power

More Geek Porn!

Energy Demand Management • Can’t control supply • => Control demand • => Energy Demand Management (EDM)

EDM Incentives • Single Energy Market • Reduced energy costs • Reduced carbon footprint

EDM Strategies • Demand reduction • Energy time-shift • Demand stimulation

Demand reduction • Diesel Generators • Heating and • Cooling Thermostat Control

Energy time-shift • Refrigeration • Ice Bank Air Conditioning • Storage heating • Smart Domestic Appliances

Demand Stimulation • Swimming Pool Heating • Plug In Hybrid Vehicles • H2 production

Conclusion • Wind power has massive potential • Wreaks havoc on grid • EDM can counter the instability • => Greater use of wind energy
