Improving RELIABILITY and mitigating
RISKS to the Bulk Power System
Common Mission

Improvement Is the Goal
We have very reliable systems within
MRO/SPP, but we can still improve by
identifying problems and fixing them – no
weak links
There is always opportunity for improvement
within the design criteria of an
interconnected system

Demystifying Internal
Controls
No, Really… What Is an Internal Control?

Nothing New
Registered Entities have been managing
reliability for decades – they have
management practices (i.e. controls) around
reliability
Existing practices have been translated into
the Reliability Standards and documented –
“operationalizing compliance”
Don’t overthink “internal controls”

Definitions
Risk
• Possibility that something undesirable will happen
• Measured as a combination of likelihood and impact
Control/Control Activity
• Policy, procedure, checklist, etc. designed to minimize
the opportunity for a risk to be realized
Internal Control
• Control activity performed internally, not by a third
party
• Management practices that include control activities
performed internally (“self monitoring”)

Types of Risk
Inherent Risk
• Risks “built-in” to a given entity, based on geography, what
facilities it operates, “interconnectedness,” etc.
• Reliability Standards are designed to mitigate inherent risk in a
broad sense
Control Risk
• Risk that management practices or control activities are not
achieving their reliability or compliance objectives
Detection Risk
• Risk that possible violations are going unnoticed
Residual Risk
• Risk that remains after application of a control and other
mitigating factors
• Difficult and expensive to eliminate 100% of risk – we must live
with some risk

Types of Controls
Preventive
• Controls designed to stop something from occurring
Detective
• Controls designed to identify when a possible violation
has occurred and facilitate timely remediation
• Also known as “Monitoring” controls

Control Hierarchies
Multiple, complementary controls that work
together to reduce risk (“Defense in depth”)
• Primary
• Secondary
• Tertiary
Secondary and Tertiary controls serve as a
“safety net” in case the Primary control does
not function as expected
Each subsequent tier of controls further
reduces residual risk

Examples
Protection System Maintenance and Testing
• Relay technicians complete work orders according to a
pre-defined checklist to prevent steps being skipped or
performed incorrectly
• Supervisors review and approve completed work
orders to verify technicians’ proper use of the checklist
• A sample of work orders is reviewed by Internal Audit
to verify accuracy and completeness

Examples
Training
• Management establishes training objectives and
reviews training materials to confirm objectives are met
• Individuals are tested after completion of training to
ensure effectiveness of delivery
• Supervisors conduct performance observations to
verify past training has been effective and to identify
additional training needs

Cybersecurity
• Systems are configured to require passwords to
prevent unauthorized access
• All changes to systems are reviewed, approved, and
tested to ensure that unauthorized changes do not
occur
• Periodic reviews are conducted to ensure that
password controls adhere to corporate security policies

Current State
“One size fits all” compliance model
• NERC Actively Monitored Standards do not change based
on regional differences, entity size, etc.
• No consideration of management practices (i.e. controls)
around reliability standards
Zero-defect approach to enforcement is
burdensome
• Every violation requires a regulatory filing regardless of
severity
• Self-reports require significant effort
Administrative Citation Process (ACP) & Find,
Fix, Track (FFT) are not sufficient
• Expediting enforcement won’t solve the problem

based on risk
Reserve enforcement for most significant
risks

Scoping of Work
What does a risk assessment look like?
• Not a letter grade or single rating
• Entities will not be compared and ranked
Assessment will look more like a matrix
• Certain families of standards may be higher risk for
one entity, less risky for another

Scoping of Work
Internal controls established by each entity must
be identified
Evaluation of select controls to determine
effectiveness
• Design – Is the control, as documented, adequate to
address the risk?
• Operational – Is the control implemented as designed?
Effective controls reduce residual risk to an
acceptable level
MRO staff can rely on effective controls
• Regulatory scope can be adjusted – less auditing and
testing (or none) where strong controls exist

Scoping of Work
Risk assessments and internal controls will
be leveraged across all compliance
monitoring activities
Internal emphasis should shift over time
toward maintaining effective controls around
Reliability Standards
• Continue to identify and correct issues in a timely
fashion
• Focus on reliable operations first
• Compliance should be a natural outcome of strong
operations

Compliance Exceptions
“Compliance Exceptions” represent lower
risk violations
•
•
•
•
Do not represent significant risk to the BES
Identified by an entity itself or by regional staff
Initially tracked at the regional level
No enforcement proceedings, no penalties
Mitigation will always be important
• What was done to address the problem itself?
• What is being done to prevent recurrence?

Compliance Exceptions
Enforcement will focus on most significant or
high-risk issues
• Violation poses significant risk to reliable operation of
the BES, e.g. cause or contributing factor in a
cascading event
• Multiple smaller issues may aggregate into a bigger
problem or are indicative of a poor control environment
• Willful misconduct

MRO Pilots
Compliance audit
• Tools being developed with input from industry, the
Regions, and NERC
• Currently developing risk assessment
• Internal controls evaluation to occur during June & July
• Scope will reflect risk and presence of effective
controls
• Audit completion in Q4 of 2013

MRO Pilots
Self-certification
• Transition from blanket, “check the box” approach to
narrowly focused self-certifications
• Scope limited to FAC-008-3 R6 based on problems
identified on recent audits
• Focus on self-assessment process and on controls to
identify and correct problems
