Cost Allocation


Bill Analysis and Rate Modeling

•Validate Bills

•What‐If Scenarios

•Share Cost Data


Analysis


• Validate performance to EE Mandates (EPACT, EISA, EOs)

• Benchmark against other facilities

• Document results so you can verify efficiency program financial benefits

• Validate utility bills, document errors and identify false penalty charges

Measurement and Verification


• Increases accuracy of projections

•Normalizes energy by weather, square footage, production volume, etc.

• Integrates relevant external data, e.g. equipment efficiency ratings, age, space, occupancy, etc.

•Gauges dependencies and outcomes

Energy Modelling


• Aggregate data from different sources and organizes into multiple hierarchical views to support each user’s needs

• Reveal complex relationships between different influences

• Display historical or predicted trends in different time dimensions

Reporting and Trending


Emissions Reporting


Minimize Power System Downtime– Proactively assess power quality trends and conditions to identify

vulnerabilities– Analyze power distribution system performance during an event– Modify the power system to prevent similar problems in the future– Accurately detect and capture magnitude and duration of power

quality events– Verify reliable operation of power distribution and mitigation

equipment– Baseline power quality conditions and verify improvements as a

result of equipment upgrades

Generator Monitoring and Testing

“Power reliability and quality are very important to us,” said Dean Salisbury. “We definitely need stable, reliable power for all the high‐tech equipment we have consistently running in our hospital.”


Load preservation

Automatic transfer schemes

Load shedding / peak shaving

Energy and Power Management Power system controls

Automatic utility or generator selection

Control peak demand levels or ensure critical load continuity

Stabilize critical power systems by monitoring utility power sources plus generation capacity versus total circuit load.


Metering & Controls Facilitate Energy Surety

Arc Fault MitigationCan save a substation

SER can pinpoint a rootCause is minutes vs. hours or days (downstream PCC)

MAINS and INTERCONNECTWhere DER is in continued parallel operation, high speed control allows preservation of the most critical load, even potential export of DER

1b ‐ High speed grid data, Freq.Triggers armed loads to shed, site wideRelaying and control retrofits and analysis

1c – Dynamic control relies upon knowingPrecise load data, even if it is several seconds old

Rotating DER sources can be used as an anchor resource to safely repurpose grid tied solar, fuel Cells

Traditional AMI data/metering

Reliable SCADA, with near time load data andReal time source data is the key to “State of the Art”Microgrid controls. System Stability data is the other key

What is a Microgrid?

Critical Loads

Distributed Generation

ControlsTo “Island”Stability

An integrated energy system consisting of interconnected loads and distributed energy resources which as an integrated system can operate in parallel with the grid or in an intentional islandedmode.

Electrical Distribution Protection and Control

Have to have:• Distributed Generation

(conventional or renewable)• Critical loads• Controls to Island and shed

o preserving critical loads and system stability

• Electrical Distribution Protection and Control

Usually have:• Inverter based generation sources• Storage or load flexibility• AMI and SCADA Software• A communications network• Sequence of Events Recording(SER)


What is a Microgrid?

In Normal Operations

Utility Meter

Switch

On-site renewablesand power generation facilities utilized in parallel with grid

May be possible to sell excess power back to the grid through a net

metering contract

Microgrid will generate energy from local sources in the case of a grid outage OR other external event which makes local energy more desirable

In an outage or event,the microgridcontroller closes connection to the grid as needed

Optimization Use Cases

Confidential Property of Schneider Electric

|

• Shifting the electrical consumption from on peak hour to off peak hour, while ensuring the comfort of the occupant• Example 1: charging an energy storage

system during off peak period and discharging it during on peak period

• Example 2: consuming electricity with a HVAC during off peak period (pre heating or pre cooling) and reducing its electrical consumption during peak period

Use Case:Tariff management – Load shifting

Energy bill optimization

• Optimizing DER Start/Stop based on electricity tariff and building occupancy• Example 1: starting and stopping an

HVAC system at the right time during the day for ensuring the comfort of the building occupant and avoiding wasting energy

Use Case:Tariff management –optimum start/stop


Energy savings and energy bill optimization

• Optimizing when to charge and discharge your energy storage device based on electricity tariff • Example 1: charge batteries during low

tariff periods • Example 2: discharge batteries when

tariffs are high

Use Case:Tariff management – Battery Integration


Discharge at high price periods

Charge at low price periods

• Shaving the consumption peak in order to reduce demand charge or to avoid paying penalties• Example 1: shedding an HVAC during a peak

consumption period, while ensuring the comfort of the building occupant

• Example 2: discharging an energy storage system or turning on a distributed generation asset during a peak consumption period

Use Case:Demand charge – peak shaving


Energy bill optimization

• Consume energy produced locally first, import energy second• Example 1: charging an energy storage system with the extra amount of electricity produced by a PV system and consuming it later during the day

Use Case:Self‐consumption


Being greener and energy bill optimization

• Performing load curtailment following a Demand Response request

• Can be performed as demo “manually” or via OPEN ADR with a utility / commercial aggregator who can bid on the energy market• Example 1: answering and performing

automatically Demand Response requests (for instance load curtailment with a HVAC or an energy storage system) sent by a commercial aggregator through OPEN ADR

Use Case:Demand Response – Load curtailment
