Demand 101

• Peak demand addresses instantaneous vs
  cumulative demand
• Peak demand is based on average load (kW) during
  an interval
• Highest 15,30 or 60 minute interval sets monthly
  charge
• Keeping the peak lower creates monthly savings

6
Demand 101

• Demand charges typically 35 of overall electric
  bill
• Energy Director lowers demand (kW) by 10 40
• Reducing demand has significant effect on overall
  bill
• Safely reducing demand in automated fashion
  enables demand response participation

Demand Savings 101

• Savings calculation

Monthly Peak Demand (kW) - Peak Demand
Reduction via Energy Director (kW) Peak Demand
Savings Peak Demand Savings (kW) X per kW
Monthly Savings per utility rate schedule
8
Demand Savings Opportunity

• Peak demand savings from 10 to 50
• Opportunities for plants sized from 1000kW to
  50MW
• Project costs follow savings and application size
  so total project paybacks range from 2 to 28
  months
• Monthly savings have ranged from 1,000 up to
  over 18,000
• All of this, with no impact to production or
  building comfort

9
What about production comfort?

• The Energy Director will achieve savings without
  any impact to production or building comfort no
  compromises
• Our high-level prediction control keeps
  frequency and duration of actions low, keeping
  them tolerable
• Strict user-developed rules protect each load and
  the function they serve

• Peak reduction project by demand shifting 513kW
  (26) savings
• Turnkey project payback 16 months

12
Why Powerit?

• The Energy Director has met and exceeded the
  quoted cost savings on our monthly energy bills.
  It has caused us to start looking at other areas
  in the operation besides the furnaces where the
  Energy Director might allow us to reduce our
  energy cost even more.
• Jerry Dale, Plant Manager, Foote Foundry,
  Fredericktown, Ohio

13
Case Study San Jose Mercury News

• Demand Control
• San Jose Mercury News - San Jose, CA
• Large Newspaper Facility
• Direct reduction of HVAC loads during demand
  spikes no decrease in building comfort
• Peak reduction project by demand shifting 600kW
  (20) savings
• Project cost 78K
• Annual savings 73K
• Turnkey project payback 13 months

14
Why Powerit?

• The Energy Director is extremely easy to use.
  There has been no impact whatsoever on operations
  or product quality and our savings are about 65K
  per year.
• Larry Benanti, Director of Engineering, San Jose
  Mercury News

15
Demand Management vs. Demand Response

• Definition of Demand Management Understanding
  where, when and why demand spikes occur and
  taking ongoing, automatic measures to reduce them
  or shift them with minimal impact on facility
  operations.
• Definition of Demand Response Event-based
  changes in electric usage by end-use customers in
  response to changes in the price of electricity
  over time, or to incentive payments designed to
  induce lower electricity use at times of high
  wholesale market prices or when system
  reliability is jeopardized.

16
Market Pain

• Extreme industry concern about meeting peak
  energy demands
• Rising consumption, constrained distribution
  infrastructure, rising costs
• Spurring Utilities towards more aggressive
  demand-side management
• Movement to add higher rates during periods of
  peak usage
• Incentives for customers that can reduce demand
  upon request (Demand Response)
• Demand management cheaper and cleaner than
  building new plants
• Industrial users hit particularly hard
• Largest individual energy users peak demand
  charges significant
• Shedding loads a difficult tradeoff if
  jeopardizes production/quality/safety
• Few alternatives to enable cost reduction or
  participation in DR initiatives
• Motivated market needing a compelling solution

17

Intelligent Load Shedding

• Intelligent load shedding software for Industrial
  environments
• Key element of Powerit Solutions advantage
• Proprietary predictive software algorithms for
  sophisticated load shedding
• Perfected and innovated through hundreds of
  customer experiences
• Small, incremental, temporary and coordinated
  shedding across a wide variety of loads
• Waits until the optimal time and only applies for
  the minimal duration
• Infinite set of rules for constraining and
  prioritizing shedding while protecting load
  functionality
• Gives customers confidence to automate energy
  management without impacting production, quality,
  safety, or comfort
• Users control the system load shedding can be
  linked to process controls giving them
  coordinated control

How does the system work?

• Automated peak load management
• System connects directly to the utility meter to
  obtain real-time billed usage data

• This ensures the data used for the timing and
  duration of load management directly relates to
  the bill

21
How does the system work?

• The user establishes a target kW allowance

22
How does the system work?

• The Energy Director uses real-time energy data to
  calculate and predict upcoming peaks based on
  allowance or setpoint

23
How does the system work?

• The controller uses connected equipment to shift
  overall plant load at just the right moment, for
  just the right amount of time, thereby avoiding
  the peak(s)
