Utility Metering vs. Submetering

04/11/23 New PowerPoint Template

Utility Meter

Meter provided by utility with the purpose of measuring an energy source to generate a bill.

Submeter

Submetering is the installation of metering devices to measure actual energy consumption after the primary utility energy meter.

Key Markets


Commercial Real Estate (owners, property manager, facility/energy manager) REITs Multi-site Retail Multi-tenant

Demand Response (CSP & Utility)

Industrial/Manufacturing/Processing (plant engineer)

Consulting Engineers (energy efficiency program coordinators)

Institutional - K-12 & Universities (facility manager, sustainability coordinator)

Solar PV/Renewable Energy (monitoring provider, equip manufacturers)

Government (regional energy managers, REMs)

Data Center (facility managers)

OEM (equip manufacturers)

Why? Expected Savings

Applications


Historical (Still Growing…)

• Tenant Billing• Cost Allocation• Energy Management (M&V, LEED; PV; O&M)

Growth Applications

• OEM• Critical Power (Datacenters)• Demand Response• Integrated Metering Solutions (Systems not components)• Plug Load Metering• Energy Efficiency driven by Codes and Mandates• Services for end-user driven by energy information

6

Growth Applications


Metered Panels• Existing and new electrical panels

Repurposed Building Space• Existing buildings continue to be repurposed. When this happens,

building owners require spaces to be metered to allocate utility costs or simply for energy efficiency (Energy Codes & Mandates)

Critical Power (Datacenters)• Cloud computing is driving growth of 24/7 facilities where monitoring

and managing power is critical, especially with PUE (Power Usage Effectiveness) essentially ratio of total amount of energy used by a data center facility vs. energy delivered to computing equipment.

Energy Efficiency driven by Codes & Mandates• From EPAct 05 to Seattle Energy Code, adoption of metering

mandates and compliance continues to expand.

7

Growth Applications


Demand Response• C&I taking advantage of utility/municipal incentives to curtail

energy use on demand.

Generation• PV and Wind

OEM• EVSE, Electrical Panels (including lighting), Inverters• (DC) Telecom and PV

Plug Load Metering• Most estimations of plug loads range from 10% to 30% of a

building's electricity use.

Technology Trends


Integrated Platforms / Advanced Communications• Shift to smart, network enabled meters that have advanced

communications. Even BAS moving to server based solutions. Self commissioning preferred.

Software / Mobile Applications• Meter isn’t enough. Customers are demanding low cost (free)

software and mobile applications that allow them to easy access information and to configure devices.

Wireless Metering• WiFi, Zigbee, 900MHz, Cellular. Customers want a low cost

option for cloud enable devices.

Rogowski CTs• Easier installation; less inventory; excellent for BAS, system

integrators, ESCOs etc..

Metering & Market Challenges


We interviewed our largest customers and asked what was most challenging about implementing metering technology:

1.Most metering projects were for main building-level metering and installation costs were generally higher than the cost of hardware2.Electricians did not understand communications protocol or wiring and were not accustomed to carrying a laptop3.Most metered spaces did not have a receptacle to power devices for communications needs (wireless, cellular)4.Service size and type weren’t always accurate or known5.Panel space was often limited and CT installation proved challenging6.Cost of communications – LAN and Cellular7.Inability to easily share data with multiple systems8.Need for installation and commissioning services9.SMB users didn’t have internal expertise for continuous commissioning10.Regulatory concerns (compliance / billing)

Small / Medium Commercial Building

04/11/23New PowerPoint Template

Small/Mid Size Commercial Bldgs.• Owner needs low cost system for main energy

sources (could be multi-site need)• Wants remote access & ability to share data

with the cloud• Option to read data manually/download data• Wants an open / scalable solution

Where can NEMA help?


• Legislative, Regulatory, Education• Lobbying cities to adopt submetering ordinances and mandates

• Outreach and marketing tools to boost awareness• Example – NEMA’s Building Tool Kit

• United group to have a voice in industry regulations

• Certifications• Example: CA W&M vs. Measurement Canada

• Forum for industry leaders to collaborate & drive growth in the industry
