About eCurv

• Venture-backed Cambridge, MA company founded in 2011• Awarded a seminal USPTO patent for the digital “queueing” of energy loads

onto a shared energy source…i.e. the “grid” in July, 2012• Successfully completed year-long evaluation with a Fortune 15

telecommunications company – currently negotiating an MSA for system wide deployment

• Ongoing integration of our software with BacNET automation systems for implementation in commercial and municipal properties

• Management team deeply experienced in Software Development, Systems Integration, Cyber-Security, and Market Development Strategy

eCurv’s Technology Foundation

Queuing algorithms have enabled the profitable and virtually unconstrained growth in the number of customers served and amount of data transported by the Mobile Telecommunications and Information Technology sectors.

eCurv's patented access control technology delivers the same benefits of scalability and flexibility to both end users and grid operators.

Our network driven queuing solution, delivered directly to utility customers, limits coincident peaks, reduces endpoint costs, and expands both the resiliency and utility of congested power lines.

The Problem:Demand charges for the entire month are based on the highest 15 minutes of demand.

What You Useone month electricity usage metered in 15 minute increments

Peak Demand = What You Pay

4% of the peak energy used drives 36% of billed demand charges

The Solution:By dynamically “queueing” 4% of HVAC peak energy, eCurv can eliminate 40% of cooling costs.

Typical Demand Profile Demand Profile with eCurv Applied

Cutting-edge software

Typical DemandHVACs cycle randomly, driven by thermostats, leading to unpredictable run times that do not take electricity usage or costs into account.

Optimal DemandHVACs are operated for optimal performance, queued to mitigate instances of high demand without decreasing end user comfort, adding a layer of intelligence to the way an entreprise consumes electricity.

From queuing roof top units to entire real estate portfolios — even across geographic locations — eCurv’s software-as-a-service provides the intelligent electricity access control needed to achieve savings on a feeder by feeder basis.

Scalable Implementation Path

Existing BACnet controlled property Add eCurv micro-server + pulse meter SCADA device controls installed Add eCurv site controller + pulse meter Thermostat only controls Add partner BACnet + eCurv micro-server + pulse meter

A Solution to Grid Congestion & Modernization

Step 1: Baseline analysisStep 2: Connect to eCurv’s cloud servers via VPN Ethernet or secure M2M wireless network Step 3: Start limiting demand and gaining electrical insight

Elegant, Secure and Scalable

Firewall / Load Balancer

Real time data streams

1. Load requests access to eCurv’s Network2. eCurv authenticates data source in Load Registry, submits

remote registered device to Core Application Servers3. Operational instructions calculated based on time of use,

ambient conditions, and customer demand profile4. Access grant instructions transmitted to remote load

Case Study: Telecom Operator

•Successfully field tested for over one year•Approved by multiple corporate constituencies (technical, operational, senior management)•Master Services Agreement in process, paving the way for the distribution of eCurv’s technology across entire 58,000 site network• Sites in operation: 1,000 in 2014 – 4,000 in 2015 – 10,000 in 2016 – 20,000 by 2017• Projected annual gross savings: $20,000,000

1% Peak Energy Responsible for 21% of Peak Demand

Business Case:• 6,400 kW peak mitigation• $1,037,000 upfront investment• $474,200 annual savings*

• 27-month payback

eCurv Implementation• Maximum queue of 6-minutes• 3,200 loads (5 kW each)

* Net Savings after eCurv’s annual software service fee

Case Study: Massachusetts Municipal Utility

Results:

• Increased Service Capacity• User controlled Grade of Service

(GoS)* • Imperceptible change in service

quality• Electricity delivered for less cost• Easier integration of renewable

resources• New foundation for electricity

distribution* Grade of Service is the probability of loads being queued during a given period of time
