Legal Update
• U.S. Court of Appeals – DC Circuit denied a
request to halt implementation “until” the
legality of the issue is addressed.
• Court fast-tracked consideration of the legality
to June 2nd – Legality of CPP.
• Irrespective of this outcome, expectations are
high for U.S. Supreme Court to hear the case.

FERC Staff Paper (# AD 16-14-000)
• FERC Staff issued “white paper” to support the
EPA-DOE-FERC Coordination effort.
• Recommends 4 principles to assist with Reliability
focused planning for CPP analyses
–
–
–
–
Transparency and stakeholder engagement*
Study methodology and interactions between studies
Study inputs, sensitivities and probabilistic analysis
Tools and techniques
• Cites typical reliability studies to be considered in
conjunction with integrated gas-electric simulations*

CNEE – Compliance Design & Evaluation
• 5- state model –MT, WY, UT, CO and NM
• Evaluate CPP compliance and design
• Focus to bring in other 7 western states

NERC Reliability Considerations Report
• Focus: Inform state regulators (environmental
and rate-payer), stakeholders and executive
branches of reliability aspects of BES.
• Findings are neither “prescriptive” nor “an allinclusive” review.
• Underscore the elements of reliability that states
need to consider as they develop their CPPImplementation Plans.

NERC Report- 1
• Core advisory team representative of different
NERC regions (WECC was a member)
• CPP NERC taskforce reviewed report produced by
core advisory team.
• Extra efforts taken to ensure focus on Reliability:
– Costs of compliance / market design not a driver
– ISO/RTO and non-ISO/RTO frameworks were given
due recognition.
– Sensitive to future “multi-state” compliance plans.

Broader Intent- NERC Report
• Facilitate a dialogue as issues/need arise
• Engage NERC or regional entities as reliability
studies are being undertaken/requested
– WECC is available to assist and learn from any
local/regional reliability studies
– Continue to enhance internal capabilities
• WECC is committed to an Interconnection-wide
perspective of Reliability assessment of CPP.

Essential Reliability Services (ERS)
• Driver: Changing resource mix – Needs voltage
control, frequency support and ramping flexibility
• ERS report offers a suite of recommendations:
– Observe trends, reliability measures and recommend
use of industry practices.
– Options for Sys-Operators to modify real-time
operations
– Further examination of the forecasting, visibility,
controllability and participation of DER as an active part
of the electric grid.

Potential Reliability Implications of CPP
• Resource mix and adequacy challenges –
– Are the renewable resources available on peak?
– Is transmission availability adequate?
• System Stability –
– Will path flows change across the interconnection?
– Will system remain stable and within ideal “frequency”
and “voltage” limits?
– What unknown issues will arise?
• Operational effects –
– Will the system have the flexibility needed to meet ramp?
– Will natural gas be available when and where needed?

Future Data needs
• Detailed information on retirements and new
resources (turbine types, location, capacity
factor)
• Specificity on attribution of multi-state
compliance, if retiring units are jointly-owned or
jointly-operated
• Renewable energy growth criteria
• Treatment of energy efficiency in plans
• Better data on intra-state and inter-state gas
pipeline flows (contingency events)
