1 G3-PLC and large scale roll out European Utility Week, October 16 th,

2 Enexis is a Dutch DSO preparing for large scale roll out Enexis Roll out will scale up in 2015 = Enexis area Since 2012 all meters that are installed in the Netherlands are smart meters New buildings Regular replacements The Dutch Ministry has asked DSO s to scale up roll out in % of Dutch customers will get an offer for a smart meter by 2020; installation target is a minimum of 80% Meters (million) , ,0 Supplying electricity to 2.6 million customers and gas to 2 million customers Currently operating 360k smart meters (8% of total customer base): 200k smart electricity and 160k smart gas meters (gprs) , ,0 0, '11 '12 '13 '14 '15 '16 '17 '18 '19 '20 total per year 2

Enexis plans to use G3-PLC as the communication technology for the large scale roll out PLC has a lower Total Cost

PLC PLC meters are less expensive than GPRS meters PLC data communication costs are much lower than GPRS costs PLC

communication technology in Europe Enexis needs to achieve the lowest possible cost for smart metering because

2 G3-PLC has an impressive design: Ø enabling end to end IP communication Ø strong security Ø robust communication

3 Enexis plans to use G3-PLC as the communication technology for the large scale roll out PLC has a lower Total Cost of Ownership than GPRS 4 reasons why Enexis selects G3-PLC 1 Although GPRS performs very well, Enexis will switch to PLC PLC meters are less expensive than GPRS meters PLC data communication costs are much lower than GPRS costs PLC does not result in a vendor lock in with a telecom provider (fixed sim card) PLC is the most widely used data communication technology in Europe Enexis needs to achieve the lowest possible cost for smart metering because Enexis is spending public money and the Dutch business case is tight. 2 G3-PLC has an impressive design: Ø enabling end to end IP communication Ø strong security Ø robust communication G3-PLC is an international open ITU standard 3 Major global DSOs are driving G3-PLC: ERDF and TEPCO 4 G3-PLC is powered by an Industry Alliance with 47 members (including DSOs)

4 Enexis has implemented a secure and interoperable G3-PLC system LV substation GPRS/UMTS/4G G3 Gateway G3-PLC Full security implementation Smart metering should be as secure as electronic banking - Dutch Minister of Economic Affairs - G3-gateway As an alternative solution to a store & forward Data Concentrator Enexis uses a DLMS Gateway (router) supporting all-ip connections Meter Interoperability Two meter vendors supply the G3-PLC meters

The results of the Enexis field trial are very good Pilot setup G3-PLC* performance is comparable to GPRS Performance ü 97% total (including 2 specific cables with

6 The Enexis decision to go to large scale roll out with G3-PLC is a big one and is not taken lightly 1) Large scale roll out of smart meters is a big investment IPv6 Secure Robust 2) Smart meters systems are new and G3-PLC is a new technology ) It is an investment for the long term: the meters will be in the grid for more than 20 years

Firstly: Large scale roll out is a big investment: will G3-PLC lower TCO significantly?

their energy consumption by 3,5% on average Ø For Energy suppliers the roll out is cost neutral, they are

smart meter roll out and operational expenses Ø Enexis tariffs are regulated and these must not be

Ø Enexis needs to achieve the lowest possible cost for smart metering because Enexis is spending public

7 Firstly: Large scale roll out is a big investment: will G3-PLC lower TCO significantly? Dutch Business case Ø Customers are the beneficiaries of the roll out, since they are expected to reduce their energy consumption by 3,5% on average Ø For Energy suppliers the roll out is cost neutral, they are projected to reduce some operational cost, but will sell 3,5% less energy Ø The DSOs have to pay for the smart meter roll out and operational expenses Ø Enexis tariffs are regulated and these must not be affected by the smart meter roll out: DSOs have to finance the roll out by general cost reduction. Ø Enexis needs to achieve the lowest possible cost for smart metering because Enexis is spending public money Ø Smart meter roll out at Enexis is estimated at 800 million (Capex & Opex) Ø PLC has the potential of 25% reduction: 200 million

Secondly, G3-PLC is new: the foundations are in place, but large scale deployments will

2008 2009 2010 2011 Ø International contest for the design of G3-PLC Ø Founding of the

8 Secondly, G3-PLC is new: the foundations are in place, but large scale deployments will start in 2015; is it too new? Ø International contest for the design of G3-PLC Ø Founding of the G3-PLC Alliance Ø ITU standard published Ø First G3-PLC products available Foundations are in place ü Alliance ü Published standard Ø More industry players developed products (chipsets, meters etc.) Ø Successful interoperability tests Ø Certification labs up and running (conformance, interoperability and performance) Ø Large G3-PLC tenders Ø Large scale deployments in France and Japan ü Industry support ü Interoperability ü Certification process ü Availability of products Large scale deployments start in 2015 Ø Same planning as the Dutch large scale roll out Ø Enexis will have to plan a first step to verify G3-PLC at an industrial scale

Thirdly, a G3-PLC smart metering system is an investment for the long term; will it evolve to meet future needs? 2015 2020 2035 Will G3-PLC still be supported in the future?

9 Thirdly, a G3-PLC smart metering system is an investment for the long term; will it evolve to meet future needs? Will G3-PLC still be supported in the future? Will the standard and products evolve and adapt to possible future needs? Smart Grids & Smart Metering Smart Homes Ø ERDF will install >30 million G3-PLC meters until 2020 Ø G3-PLC applications for smart grids are being developed ü Availability and evolution of G3 will be accelerated by the ERDF roll out This October the Japanese Government and TEPCO have selected G3-PLC as the wired technology standard for In Home communication (meter to HEMS) ü G3-PLC will be part of the Japanese Smart Home future ü The leading Japanese Electronics industry will invest in the G3-PLC technology and develop G3-PLC products ü The G3-standard will be used at an industrial scale worldwide

Enexis will prepare the large scale roll out to begin in 2015 IPv6 Secure Robust 2015 2020 2035 G3-PLC

G3-PLC is fit for the future with major Utilities investing in G3-PLC 2013 2014 2015 2016 2017 2018

10 Enexis will prepare the large scale roll out to begin in 2015 IPv6 Secure Robust G3-PLC will lower our TCO significantly G3-PLC is new, but still 2 years to go before the start in 2015 G3-PLC is fit for the future with major Utilities investing in G3-PLC Decision Tender & development Large Scale Roll out GPRS G3-PLC.and we will be helped by the work of:
