Brief Explanation of the Energy Objects•Base Energy Object:– Allows devices to report their energy usage in a standardize way using kWh•

Electrical Energy Object:– Reports a variety of electrical measurements• Voltage, current, power factor, frequency, etc.
• Such as used in a meter or power monitor– Is subordinate to the Base Energy Object•

Non-Electrical Energy Object– Reports the usage of energy resources• Natural gas, steam, fuel oil, hot water, chilled water, etc.
• In the resource’s native energy unit – therms, pounds, galllons, BTU, joules, etc.

– Also subordinate to the Base Energy Object

Brief Explanation of the Power Objects•

Power Management Object:– Standardized interface for devices and systems to enter low-power modes– During periods of need; such as lunch, shift change, weekends or other idle periods– Devices reduce energy usage to predefined modes (paused, sleep, wake-up, etc.),
in expressed notification times•

Power Curtailment Object:– Creates predefined curtailment levels to reduce power in devices and systems– Here the energy management application requests a desired power level instead ofa pause in energy usage•Together:– Service an energy management application client– Provide a child/parent energy management cascading control

– Changes in the market, the stronger concern over energy usage
and management support the need for a restart• The Global Energy Management System Market
currently worth $55.2 billion is expected to grow to$208.4 billion by 2032.*– Compound Annual Growth Rate (CAGR) of 14.6%*Research by market.us

The Renaissance•

Customer driven reasons for a restart:
–––––

•

Ease of integration into their energy savings strategies
Pressure to reduce Global GreenHouse Gases (GHG) emissions
Reduced cost of implementation with a standardize approach
Can use a multi-vendor solution (not locked to a single vendor)
Higher Return On Investment (ROI) available now

ODVA is a founding member of the Power Consumption Management
Group– Joint Consortium with OPC Foundation, VDMA, and PI– An OPC United Architecture (OPC UA) Power Consumption Management
specification will be written• With the goal: “to harmonize and standardize energy consumption information on
the shop floor”

The Renaissance• Net-Zero Carbon emissions!
– The World Economic Forum is driving to have net-zero carbon emissionin all markets.

– “With industry responsible for 30% of global CO2 emissions,industrial clusters will be a critical player in accelerating the path
towards net zero.”https://initiatives.weforum.org/transitioning-industrial-clusters/homeTechnical Track© 2023 ODVA, Inc.

The Evolution Process•

It is time to update and evolve the ODVA Energy Applications SIG– ODVA members need to reengage• Must be a multiple member effort, cannot be just 1 or 2 companies• Will need to attend regular meetings– Time to renew the work on the Energy/Power Objects•••••

Complete the Power Management Object CIP-SE with needed enhancementsUpdate the Power Curtailment Object for modernization and alignments
Revisit the three Energy Objects to provide needed updates
Rename the Power Objects to match the names of the Energy Objects
ODVA has begun to work with OPC F and other associations on energymanagement– The Energy and Power Objects must align to changes and conventions of joint
consortium, the Power Consumption Management Group• Re-establish the state-of-the-art behavior of the CIP Energy/Power Objects

A Science Interlude••Power = Work over Time (P=W/t)•Energy = Power over Time (E=P/t)

The rate at which the water leaves
the spout represents Power.

•The amount of water in the pailrepresents Energy.

The Evolution Process• After the reengagement of ODVA Energy Application SIGmembers• The easiest change is to align the naming of the Power
Objects to Energy Objects.
– Provide consistent naming for all CIP Energy Initiative objects– The Power Curtailment Object and Power Management Object
handle both power and energy;• Energy includes Power• Therefore, energy in the title is more accurate• Customers are more interested in the Pail than the just the flowing
water– Change to Energy Curtailment Object and Energy Management

The Evolution Process (The Real Work)• Complete CIPSE-0243-008 Power Management
Update– Finish the rewrite of this object to include:• Updating the cascade capability (improve the Parent/Child relationshiphandling)• Change, correct, and provide additional Instance Attributes• Ensure the currently defined energy-related states are still accurate– Validate the current requested changes• Correct the Ownership functionality– Add updates to match information from the OPC UA Power
Consumption Management specification– Change the name to the Energy Management Object• The Class Code would remain the same – 53 Hex

The Evolution Process (The Real Work)• Write a new CIPSE for Power Curtailment
Object Update– Add updates to match information from the OPC UA Power

The Evolution Process (The Real Work)• Process new specification enhancements for theBase Energy, Electrical Energy, Non-Electrical
Energy Objects– All use Odometer data type for tracking energy data
• makes sense for visual display• inefficient data type for internally managing energy data.
• integer would be a better choice– Correct the rollover behavior in all the objects– Add updates to match information from the OPC UA PowerConsumption Management specification– Include new features to reestablish state-of-the-art behavior

Conclusion• The time is right for evolving OEU in ODVA– Market growth, customer needs, government mandates (GHG,carbon reduction) support a restart• Other organizations have started the development– ODVA needs to stay aligned and add further market value• It takes a village, an ODVA Village– This evolution must be a multi-member effort• The work is well defined and partially completed– We know how to get there from here
