Controlling and reducing energy consumption at your organization
The energy-saving concept
Energy management is the process of monitoring, controlling, and conserving energy in a building or organization; it is the key to saving energy, to moderate economic risk by reducing your demand for electricity and make it more predictable commodity
• Reduce the carbon footprint and cost-related implications of carbon emissions taxes
• Reduce costs by controlling & optimizing energy consumption, promoting sustainability
• Reduce risk, the more energy you consume, the greater the risk that energy price increases or supply shortages could seriously affect your profitability, or even make it impossible for your business / organization to continue.

How best to manage your energy consumption?
Typically this involves the following steps:
1. Metering and monitoring your energy consumption while collecting the data.
Energy-data collection is to fit interval-metering systems that automatically measure and record energy consumption, allowing to identify personal patterns of power usage that it would be impossible to see otherwise.
Such load patterns makes it much easier to find the routine waste in facilities

How best to manage your energy consumption? Detailed energy data is fundamental to find rational energy savings

2. Finding opportunities to save energy and evaluate how much energy each opportunity could save.
By analyzing the electric load diagrams one can find & quantify routine energy waste, while investigating the energy savings that could made by replacing equipment (e.g. lighting, chiller) or by upgrading building's insulation.
and also
Check whether staff and timers are switching equipment off without having to patrol the building day and night. Verifying the interval details one can usually identify what is causing the energy excess.

How best to manage your energy consumption?
Studying detailed interval energy-data is the ideal way to find routine energy waste.
The rational use of energy means the optimal and efficient use of energy and does not mean frugality that affects the welfare and comfort

3. Taking action
Targeting the opportunities to save energy (i.e. tackling the routine waste and replacing or upgrading the inefficient equipment). Typically you'd start with the best opportunities first, with proven efficiency, reliability and faster pay-back.

4. Tracking your progresses
Analyzing your metered data one can see how well energy-saving efforts have worked
After investing money into new equipment, you'll want evidences that the predicted energy savings were reached
Energy-performance tracking reporting is an essential tool to analyze metered energy data and allow to track improvements

FUNDAMENTALS
It requires some appropriate notions:

Managing your energy consumption effectively is an ongoing process
Smart MetersSmart meters communicate using wireless signals and usually involve real-time or near real-time sensors, power outage notification, allowing interface with EMS / iDR.
It’s an electronic device that records power usage in intervals (30 min. usually) and communicates the information back to the utility for billing purposes.

SMART GRID Smart Grid is a modernized electrical grid that uses last generation communication technology to gather and act on information, real-time and automated to improve the efficiency, reliability, and sustainability of production & distribution of electricity.
Smart Grid may interface with iDR or BAS Building Automation Systems - smart grid compatible to manage load demand while balancing the electrical distribution

BUILDING AUTOMATION Building Automation Systems are systems of computer-aided tools used by operators to centrally monitor, control, record and improve the performance of the electrical building loads connected to the control and scheduling applications (i.e. HAVC, Lighting, etc.).
Alarm management, set-point management, are BMS applications with the purpose of alarm control & operator alert to deviations from regular operating conditions (i.e. temperature, equipment failure, etc.).
The ultimate objective is to prevent and/or minimize, physical and economic loss through operator intervention in response to the condition that was alarmed.

LOAD CURTAILMENT Load curtailment programs usually involve an agreement between the utility provider and an electric power customer that typically agrees to drop the load off the grid during periods of high power demand in return for special rates.
Some BAS can also provide applications for this purpose, transferring loads to the emergency generator or partially by disconnecting some equipment and/or reducing operation in a pre-established criteria

PEAK SHAVING
Peak shaving is a technique that is used to reduce electrical consumption during periods of maximum demand.
Most peak shaving solutions use generators and paralleling equipment which allows the emergency generator to real-time monitor the electric grid.
Peak shedding is commonly utilized to reduce peak demand penalty that utilities charge for periods of highest usage. The process starts by disconnecting sheddable loads (i.e. hvac system, non-sensitive equipment, some lighting, etc.).

Demand Response (DR)
DR is a component of smart energy demand and categorizes the process of changing electric usage by end-use users in response to electricity costs, inducing a reduced electric load profile and peak demand thus a lower carbon footprint

Coefficient of simultaneity
Coefficient of simultaneity is the property of two or more events happening at the same time in a frame of reference.
It refers to the idea that the consumption of power may occur simultaneously for multiple equipment in the same period generating a peak demand that can create an overload or a penalty in contractual power supply
TERAWATT intelligent Demand Response Technology
EU Power Management Systems LLC
Tracking your progress at saving energyThe algorithmic calculations of Terawatt iDR compares every second, real-time, the power demand and consequently optimizes load by strategically optimizing selected equipment thus reshaping the instant power and lowering the coefficient of simultaneity during the in-progress power demand (30 minute period)
The result is a reduced integration value of instant power (kW) therefore generating a adapted load profile with effective cost reduction in peak demand (kW) and in consumption (kWh).
