Multiple Tools/Systems

EMS FTR DTS Market Planning

• Duplicate efforts

• Synchronization issues

• Inconsistent solutions

• Difficult change management

• Multiple modeling practices &

processes

• Multiple users and maintainers

• Models are inherently different

• ISO – EMS, Planning, Market

• Utilities – EMS, Planning, Protection

• Transmission, Distribution

• Difficult model exchange

Common objectives

4

• Model accuracy & consistency

• Compatible solution results

Improved Compliance

• Avoid duplication

• Shorter Modeling cycle

• Process automation

Improved Efficiency

• Standard based data exchanges

• Common and consistent APIs

Improved Integration

AMEREN Modeling practices and plan

Ameren - Introduction

6

Diversified regional electric and gas

utility serving 2.4 million electric and

933,000 gas customers over 64,000

square miles in Missouri and Illinois.

• Expect strong ~6.5% compound annual rate base

growth from 2015 through 2020

• Expect 5% to 8% compound annual EPS growth

from 2016 through 2020

Key Business Drivers

7

• 2.6M Customers => 10M managed resources

• New solar resource goes online every 83 sec

• Converged T/D/IT systems

View of the Future

• Competition

• Invest in the Grid

• Aging Infrastructure

• New Standards

• NERC Alert Projects

• Changing Generation Mix

• Security = Physical & Cyber

Corporate Strategy

• 2010 $25M in T / 2016 $800M in T

• Can’t do things the same old way

Improved Efficiency

Near term objectives

8

• Terminology that translates across functions (planning, operations, market, protection, maintenance, financial) and across entities

Common Language

Shared Commitment to Dialogue

• Standards-based (CIM) databases and exchange formats

• Automation (APIs)

One Version of the Truth

Long term vision

9

• Cloud-based

• Apps (i.e. models)

• OS

• High Availability (i.e. 100%) - Backups

• Auto-detection of new devices

• Security

iNMM

• Systems and processes – think new devices every sec

Vertical Scalability

• 95+% of display work created by AI

• Validation (connectivity, ratings, etc.)

• Prediction – what will the system look like next hour, tomorrow, next month, next year?

Artificial Intelligence

• DLMPs (any point where two or more customers can transact will be a market)

Transactive Energy

Key Business Drivers

12

• Steady-State and Dynamic System Model Validation

• Improve operations and planning models accuracy and consistency

• Compatible solution results across multiple functional areas

Ensure Compliance

• Shorten modeling cycle

• Process automation – Expedited and reliable process flow

• Standardize model data submission and exchange

Improve Stakeholder Value

• Planning moving towards node-breaker model

• Coordinated data model formats

• Distributed Energy Resources

• Standard based common and consistent APIs

Capitalize on Technological Advancements

Near term objectives

13

Process review

• Engage model dependent upstream and downstream systems for process requirements and timing to reduce cycle time

Stakeholder Outreach

• Engage Stakeholder community on model building process and timing

Industry Engagement

• Engage Neighboring RC community on data exchange timing and requirements

Standardize Input

• Standardize Model Exchange format
