Public Service New Mexico and Portland General Electric show two 

ways of depicting the value of storage to their network

PUBLIC SERVICE NEW MEXICO (PNM)

• Reduced renewables curtailment

• Reduced lost load

PORTLAND GENERAL ELECTRIC (PGE)

• Storage: ~4x higher operational benefits

• 2-hr storage vs. fossil comparison

BEST PRACTICE DESCRIPTION RESOURCES AND 

EXAMPLES

NET COST OF 

CAPACITY 

CALCULATION

• This approach assesses the benefits and costs of 

storage and peakers, fully accounting for system 

needs, market rules, and technical performance

• Requires sub-hourly load data to fully capture 

dispatch patterns

• ESA IRP primer (v2.0 to be 

released in soon)

LOSS OF LOAD 

EXPECTATION DUE

TO LACK OF 

FLEXIBLE CAPACITY

• Load loss can be due to lack of flexible resources 

is a threat, particularly as intermittent renewables 

increase penetration

• Best practice modeling breaks out Loss of Load 

Expectation for both aggregate capacity shortfall 

as well as lack of flexible capacity

• Indicative modeling solutions 

include Astrape’s SERVM, 

E3’s RECAP

Best practices are emerging in assessing the value of storage within 

utility network

Utilize all-source procurements to ensure maximum customer benefits 

across the potential solution set

(PNM’s 2023 Generation RFP)

PNM’s 2017 IRP has identified the need for additional flexible 

capacity as the result of the planned retirement of SJGS and 

the growth of variable energy resources (“VERs”) on PNM’s 

system. This RFP is intended to address the need for the 

addition of 456 MW of identified capacity by no later than June 1, 

2023. The exact MW capacity requirement and the types and 

sizes of resources best suited to meet PNM’s capacity, energy, 

and reliability requirements will be determined through 

selected modeling and analysis of the resources bid in 

response to this RFP, their respective capacity factors, and their 

ability to satisfy a maximum Loss of Load Event (LOLE) metric of 

≤0.2 for both capacity and flexibility within PNM’s system. 

GUIDING PRINCIPLES

Define the underlying need and 

performance requirements without 

specifying technical solution

Define evaluation methodology

Solicit competitive bids across 

technologies and pick the 

winner(s) based on performance 

and evaluation criteria
