5. Introduction: DELTA Network Group
• DELTA Network Group is part of DELTA N.V.,
the locally owned multi-utility company;
shareholders: the Province of Zeeland & local
municipalities.
• Maintenance of infrastructure for water, gas,
electricity & cable, incorporating a DSO (“DNWB”)
• Metering and utility services (nationally)
• Added value to stakeholders through synergy,
embodied in our multi-utility strategy
• As a municipal multi-utility it is in the nature of
DELTA to focus on added stakeholder value
including sustainability, in a multi-utility approach
• We are looking for cost efficiency, innovation,
consumer empowerment & energy efficiency
through integrated offerings

6. Smart Metering in the Netherlands
Dutch Distribution System Operators:
 Government mandate for roll out smart meters for
Electricity and Gas; Dutch Smart Meter
Requirements (“DSMR”) developed by national
organization of DSO’s, “Netbeheer Nederland”
 There is no government mandate for roll out
of smart Water meters or smart Heat meters.
 However, regulations as well as the DSMR
allow explicitly for smart meters for “Water”
or “Heat” to be added as „slave‟ meters
 It is straightforward for DELTA the Multi-Utility
company to investigate the added value of
Smart Water Metering
 The solution also applies to Heat, which can be
valuable in City Heating projects & areas

8. Value Proposition for the Consumer
• Benefits for a smart meter roll out are supposed to
include energy efficiency savings
• Targets on energy efficiency must be met (“2020”)
• Savings will only materialize if customers actually
engage and change their every day behavior
• Direct feedback allows for better energy savings;
“on average an In Home Display is 50% more
effective than an informative bill at reducing
overall electricity consumption”
(© “Empower Demand” study 2011, VaasaETT/ESMIG)
• Behavioral change comes about by “experiential
learning”: learning by doing & direct feedback on your
actions
8
PoC Dutch Multi-Utility Smart Metering – October 17th 2013

9. Direct In Home Feedback for E, G & W
• we can distinguish volumes for gas attributed to heating from volumes
for gas attributed to baths and showers if peaks correlated
• we can distinguish electricity used for washers & dish washers from
other uses of electricity if peaks correlated
• Consumers can draw their own conclusions based on near real time
information and act
• Our Proof of Concept enables this in basic format

PoC Dutch Multi-Utility Smart Metering – October 17th 2013

10. Bonus value: data for Benchmarking & Targeted Advice
Algorithms on combined smart meter data history
E, G & W could (off scope in PoC) generate targeted
advice by comparing data to relevant benchmarks
 Advice for home equipment; heating, tap water
heaters, bathroom use (shower) and (dish) washers;
 Advice on insulation measures w.r.t. the home
 Services can be based on secured smart meter data
from the national data hub, market interface “P4”
 Services can be offered to consumers by
ESCO’s, Water companies or Energy Suppliers
Consumers relate to comparisons with other
consumers (peer pressure)  behavioral change
 energy savings & customer satisfaction

11. Adding Smart Water Meters & Business Case
• Costs: Saving money through synergy
 Synergy during smart meter roll out
the logistics costs can be shared if a planned
and executed visit in the field leads to smart meters
for 3-4 utility services instead of 1 or 2
 Synergy during operation; if the costs for
telecommunication and maintenance are shared
for 3-4 utility services instead of 1 or 2
• Increased customer benefits through synergy
 Customers have a higher potential in saving money
and energy because of added insight
 Room for new innovative information services
(“big data”) and in home direct feedback products

15. Status R&D activity “Proof of concept MUSM &EMS”
Corporate level acknowledgement of the value of this
concept “MUSM & EMS” in December 2012
 Assignment: “develop a technical solution with partners”
 Together with suppliers of components & smart meters
we have created a working solution March 2013
 With business partners we have organized working ICT
solutions and work arounds (e.g. with Alliander)
 Deployed amongst our colleagues May/June 2013
The most critical consumers around
(they have your phone number )
 These consumers are using the solution
 Evaluation is planned by December 2013

16. Added Value
• Encrypted digital interfaces for Smart meter data for
Water or Heat as well as for Gas & Electricity
• The encrypted data in our solution is suitable for
billing  no manual meter reads or audits required 
added value for (utility) companies & customers
• Cheaper meter readings  innovative billing models
• Platform for useful innovative solutions that
integrate data from smart meters for E, G & W
• The concept further empowers customers to take
steps in saving money and the environment
• It enables sustainability benefits of reduced water
use and improved sustainability benefits for energy

17. Lessons Learned PoC; Roll Out & Asset Management
• Commissioning and installation process;
replication of processes and instructions for “gas” to
also cover “water” (or “heat”) is relatively easy
• ICT; replication of data structures & interfaces for
“gas” to cover “water” (or “heat”); relatively easy
• The roll out field tool we have used (“SmarAPP”)
supports “Water” in the same way as it supports “Gas”
without any significant modifications
• Asset Management poses a challenge;
DSO rolls out E and G and as owner of those smart
meters has all asset management processes and
information available; but the Water-meters have no
natural place in the DSO‟s ICT architecture
17
PoC Dutch Multi-Utility Smart Metering – October 17th 2013

18. Next Steps
• Research and development
• Technical research & development; follow up project
to investigate if it is feasible to enhance the
refreshment rate (hourly  5 minutes) at the “P2interface” (MBUS) between slave meters & the
Electricity-meter
• Evaluate consumer appreciation; customer value
and savings (energy efficiency) are input for the social
business case (municipal stakeholders)
• Stakeholder alignment and follow up
• We will address questions concerning [1]
architecture, [2] costs and benefits, based on the
lessons learned
• We will update the business case
• We will inform stakeholders

approach with respect .. and in
conjunction!

PoC Dutch Multi-Utility Smart Metering – October 17th 2013

21. Appendix A DSMR E-meter “P1-port”
• In the Dutch concept ("DSMR") the Smart
Electricity meter acts as the data hub for locally
connected Smart Gas, Heat or Water meters
• Combined data from slave meters available for the
consumer in a Home Area Network ("HAN") via
consumer port; the Dutch standardized P1 port
• Interface specifications for “P1” are public domain
 The DSO facilitates a level playing field for the market
players, no “lock in” for consumers
 Any party can provide customers with a device
suitable for P1 to disclose multi-utility smart meter
data to consumers in a value proposition for the
home; either wireless (HAN) or wired, based on a
device, with a display or device independent App.
