4
Why Powerit Solutions?
  • Strong base of reference-able customers in key
    markets
  • Metal Foundries Casting Plants

  • Printing Facilities
  • Cold Storage / Freezing Facilities
  • Wineries / Breweries
  • Wood Products Mills
  • More
  • Compelling customer value proposition
  • Turn-key, easy-to-install, easy-to-connect
    solution
  • Can achieve demand control without impacting
    production, quality, comfort
  • Create ongoing reduction of 10-40 in peak
    energy demand charges
  • Payback period of 12-24 months (often much less)

5
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

10
Case Study Rochester Metal Products
  • Demand Control
  • Rochester Metal Products Rochester, IN
  • Iron Castings Foundry
  • Direct, coordinated furnace load reduction to
    reduce kW demand
  • Peak reduction project by demand shifting
    5000kW (24) savings
  • Project cost 80K
  • Annual savings 723K
  • Turnkey project payback 2 months

11
Case Study Foote Foundry
  • Foote Foundry Fredericktown, OH
  • Iron Castings Foundry
  • 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
Technology Overview
  • Energy Director automatically predicts,
    regulates, and lowers peak demand
  • Turn-key solution
  • Industrial-hardened controller (hardware device)
  • Software management tools
  • Variety of networked wireless I/O (for load and
    meter connectivity enabling easy and simple
    set-up)
  • Predictive load shedding optimized for Industrial
    environment
  • Adaptive setpoint for automating savings
    management
  • Complex rulesets for load performance protection
  • Reporting for visibility into energy management
  • Savings verification reports, graphs, and
    archives
  • Utility bill matching / verification
  • Energy, temperature process reports/graphs
  • Simple Integration with Existing Systems
  • Refrigeration, Bldg, Process controls
  • Communication connectivity to major protocols
    such as LonWorks, BACNet, Modbus TCP, many others

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

20
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)

24
What can Powerit Solutions do for me?

  • Provide low risk savings with attractive ROI and
    very measurable results
  • Evaluate your facility for savings at no charge
  • Provide a written savings analysis and detailed,
