This is a lengthy post. If you want a condensed version I recommend the article published at Energy Security and Freedom blog by Tom Shepstone.
On November 4, 2024, the New York Department of Public Service (DPS) staff proposal concerning definitions for key terms (Staff Proposal) in Public Service Law §66-p was released. I described my impression of the draft definitions earlier. The DPS Staff Proposal also included a section titled “Reviewing Progress Towards Achieving the 2040 Target” that is the subject of this post.
I have followed the Climate Leadership & Community Protection Act (Climate Act) since it was first proposed, submitted comments on the Climate Act implementation plan, and have written over 470 articles about New York’s net-zero transition. The opinions expressed in this article do not reflect the position of any of my previous employers or any other organization I have been associated with, these comments are mine alone.
Overview
The Climate Act established a New York “Net Zero” target (85% reduction in GHG emissions and 15% offset of emissions) by 2050. It includes an interim 2030 reduction target of a 40% GHG reduction by 2030. Two targets address the electric sector: 70% of the electricity must come from renewable energy by 2030 and all electricity must be generated by “zero-emissions” resources by 2040. The Climate Action Council (CAC) was responsible for preparing the Scoping Plan that outlined how to “achieve the State’s bold clean energy and climate agenda.” The Integration Analysis prepared by the New York State Energy Research and Development Authority (NYSERDA) and its consultants quantified the impact of the electrification strategies. That material was used to develop the Draft Scoping Plan outline of strategies. After a year-long review, the Scoping Plan was finalized at the end of 2022. Since then, the State has been trying to implement the Scoping Plan recommendations through regulations, proceedings, and legislation. The DPS Proceeding on “Motion of the Commission to Implement a Large-Scale Renewable Program and a Clean Energy Standard” case number 15-E-0302 is the primary implementation proceeding. The Staff Proposal was posted as part of that proceeding.
Background
On November 4, 2024, the DPS staff proposal concerning definitions for key terms (Staff Proposal) in Public Service Law §66-p was released. I described the definitions earlier. This post coves the provision to review progress. The Introduction of the Staff Proposal explains:
The primary purpose of this proposal is to clarify what is encompassed within the term “statewide electrical demand system” and articulate broad criteria for compliance with a “zero emissions” standard. In addition to proposing definitions – and in light of the proposed definitions’ implications – Staff also recommends that the Commission direct Staff to develop a review process consistent with the provisions of PSL §66-p that tracks progress toward the power sector energy transition targets.
Reviewing Progress Towards Achieving the 2040 Target
The Staff Proposal acknowledges my fundamental concern that there is no real plan for implementation. The Scoping Plan is an outline of strategies that NYSERDA’s Integration Analysis claims will reduce emissions consistent with the Climate Act mandates but there never has been a feasibility analysis of the strategies. DPS Staff “believes that it is timely to interpret provisions of PSL §66-p that authorize the Commission to consider impacts of the zero emissions by 2040 target on safe, reliable, and affordable electric service in the state.” Unfortunately, the Staff Proposal focused on timeliness and short-changed discussion of safe, reliable, and affordable electric service.
The Hochul Administration and all the state agencies involved with the Climate Act transition have ignored the fact that no jurisdiction has demonstrated that an electric system relying on wind, solar, and energy storage is viable. Francis Menton, Rich Ellenbogen and I have argued that a demonstration project that proves that the proposed transition will work is necessary before implementation proceeds. This is a fundamental safety, reliability, and affordability constraint that is not addressed in the Staff Proposal. At the very least, I believe a feasibility analysis should be the next step.
The Staff Proposal addresses the timeliness of the wind, solar, and energy storage deployment but just assumes that an electric system reliant on wind, solar, and energy storage will somehow work:
Pursuing the 2040 target will require the deployment of novel technologies and their integration into a changing grid. Further, as recent experiences with pandemic, supply chain disruptions, inflation, changes to interest rates, the effects of federal policy on domestic manufacturing, and revised expectations about load growth have made plain, progress toward the target will be heavily contingent on pressures beyond New York State’s control. Staff believes the 2040 target must be interpreted and implemented without compromising resource adequacy, reliability standards, and affordability.
I am concerned with the novel technologies mentioned in this paragraph. The Staff Proposal mentions the December 2023 technical conference hosted by DPS Staff and NYSERDA discussion of potential technologies. The New York Independent System Operator 2023-2042 System & Resource Outlook (“Outlook”) Overview in Appendix F – Dispatchable Emission-Free Resources evaluates three Dispatchable Emissions-Free Resource (DEFR) options that they believe represent the most likely viable approach but concede that there still are concerns even with these:
While DEFRs represent a broad range of potential options for future supply resources, two technology pathways being discussed as potential options for commercialization are: 1) utilization of low- or zero-carbon intensity hydrogen (typically generated by electrolysis derived from renewable generation) in new or retrofit combustion turbine or fuel cell applications or 2) advanced small modular nuclear reactors, which are currently seeking approval from the relevant regulatory bodies to design and operate these resources. Currently, both technologies have shown limited commercial viability on the proof of concept. Even assuming that they are commercially viable, there remains significant work in the implementation and logistics that must be overcome to economically justify transitioning the dispatchable fleet to some combination of new technologies in the next 15 years. Long-duration energy storage could potentially serve in the role of the modeled DEFRs in the Outlook. In many respects, long-duration energy storage closely mimics various hydrogen production and conversion pathways. Long-duration energy storage adds to load in many hours, similar to electrolysis production of hydrogen. However, a notable difference is that electrolysis production of hydrogen has a lower round-trip efficiency when injecting energy into the system compared to other long duration energy storage technologies under development.
Given that none of these technologies are likely to be available consistent with the needs for the Climate Act schedule, it is understandable that the schedule is a concern. Nonetheless, I am very frustrated that DPS Staff are only paying lip service to resource adequacy, reliability standards, and affordability because there are unaddressed reasons that the wind, solar, and energy storage approach may never work with those constraints. First and foremost, the only one of the three DEFR technologies described that has no technology issues is nuclear. There are commercial readiness issues, but the technology has a proven track record. On the other hand, there are physical limitations that may prevent hydrogen technology or long-duration storage from ever working. Because a DEFR technology is needed, it is likely that the DEFR solution will be nuclear. An assessment of resource adequacy, reliability standards, and affordability impacts of a system using nuclear power would likely find that relying on nuclear instead of weather dependent renewables is a better approach. Compared to wind and solar, nuclear generation produces synchronous power that requires no additional ancillary service support, has a much lower areal footprint, and fewer life-cycle environmental impacts.
Weather Variability Risk
There is another huge advantage of an electric system relying on nuclear power. The unacknowledged resource variability risks of the wind, solar, and energy storage electric system proposed would be eliminated. I believe that there is an enormous risk associated with the specification of just how much DEFR is necessary so bear with me as I describe my concern. The Staff Proposal states that:
Comments filed since the December 2023 technical conference have highlighted the importance and analytical challenges of estimating the size of a potential reliability gap. Staff does not endorse a specific estimate of the potential 2040 gap, but it does take the view that the trends on the supply and demand sides of New York State power sector’s make likely a gap that would require at least 10 to 20 GW of clean firm generating capacity to fill. This view is informed in part by the draft analysis, recently published by Staff and NYSERDA, of recent global disruptions and other factors’ delaying effects on large-scale renewables deployment in New York. As for new technologies that could be deployed in the coming years to help New York hit the 2040 target, panelists at the December 2023 technical conference described how several show promise, but panelists and commenters also noted diverse factors that make deployment at the locations and scale required uncertain.
In my opinion, DPS Staff and NYSERDA have not yet to come to grips with the analytical challenges of estimating the size of the potential reliability gap. I described analyses of the gap in comments submitted on July 3, 2024 in response to comments submitted by Sierra Club and Earthjustice dated June 14, 2024 in the Case No. 15-E-0302 docket. I explained that all renewable resource projection analyses should use historical meteorological data to provide the basis for projections of future load and estimates of electric resource availability based on projected deployment of wind, solar, energy storage, and other technologies needed to supply the expected load. Hourly meteorological data across the state produced using current weather forecast modeling techniques yield hourly demand forecasts and wind and solar energy output profiles for the periods being studied. I believe that the State must invest in a comprehensive analysis of these data for as long a period as possible.
There has been some analysis that shows the extent of the problem. The NYISO is working with its consultant DNV to assess New York onshore wind, offshore wind, and solar resource availability. Their analysis uses a 23-year historical meteorological database for the New York State renewable resource areas. Similar analyses are underway in other regional transmission operator regions. It has also been recognized that larger areas need to be treated similarly. The Electric Power Research Institute has a Low-Carbon Resources Initiative that has been evaluating resources across the North America.
All these analyses find there are frequent and extensive periods of low renewable resource availability. For example, the New York State Reliability Council Extreme Weather Working Group (EWWG) analyzed the high resolution NY offshore wind data provided by NYISO and its consultant DNV for offshore wind resources. The summary of the report stated:
The magnitude, duration, and widespread geographic impacts identified by this preliminary analysis are quite significant and will be compounded by load growth from electrification. This highlights the importance of reliability considerations associated with offshore wind and wind lulls be accounted for in upcoming reliability assessments, retirement studies, and system adequacy reviews to ensure sufficiency of system design to handle the large offshore wind volume expected to become operational in the next five to ten years.
That analysis used a 21-year database. I think the DPS staff proposal used a shorter weather analysis database that results in the CGPP estimate being “substantially below the 20-40+ GW range estimate published by NYISO in its 2023-2042 System and Resource Outlook”. The period of record makes a big difference. I found that in a similar type of analysis, the Independent System Operator of New England (ISO-NE) Operational Impact of Extreme Weather Events, used a database covering 1950 to 2021 to analyze gap impacts. The analysis found that if the resource adequacy planning for New England had only looked at the last ten years instead of the period of record that they would have underestimated the resources necessary by 5.1% because there was a longer renewable resource drought outside of the last ten years.
Even if the State uses a longer data period there is a major reliability risk that has not been acknowledged. Current resource assessments are based on observations of existing generating resources over many years that show that unplanned outages do not happen at the same time. There is no reason to expect, for example, that all the nuclear plants will be forced offline at the same time. This characteristic enables the resource planners to conservatively determine how much generating capacity is necessary to meet the probability of losing load not more than once in ten years loss of load expectation (LOLE) reliability criterion. Importantly, I believe that the lack of correlation also means that the capacity needed above firm system load would not change substantially if the LOLE planning horizon was shifted to a longer period.
Variations in weather affecting wind and solar resource availability will require changes to electric resource planning. Everyone has heard of a hundred-year flood which is the parameter used for watershed planning. This is the one in a hundred probability that the water level in a river or lake will exceed a certain level in a given year. Similar probability estimates of low wind and solar resource availability must be developed and incorporated into electric resource planning.
Electric resource planning is complicated by the observation that the meteorological conditions that cause low wind and solar resource availability are so large that they can affect all of New York and adjacent areas at the same time. This means that wind and solar outages will be widespread, affecting many facilities at the same time. The unacknowledged issue is that the design of an affordable and practical system to meet the worst-case weather induced lull will always involve a tradeoff between practicality and affordability versus the probabilistic estimate of the worst-case lull.
An unresolved problem is what approach is acceptable for addressing these lulls. If the resource planning process does not provide sufficient backup resources to provide capacity for a peak load period, then reliability issues are inevitable. Two factors exacerbate the severity of this problem and the importance of the reliability criteria:
- Periods of highest load are associated with the hottest and coldest times of the year and frequently correspond to the periods of lowest wind resource availability.
- The decarbonization strategy is to electrify everything possible so the impacts of a peak load blackout during the coldest and hottest periods will be greater.
I think that the reliability planning process should use as much historical data as possible to define the worst case. Consider the ISO-NE analysis where it was found that the most recent 10-year planning lookback period consistent with current LOLE evaluations would plan for a system risk of 8,714 MW. If the planning horizon covered the period back to 1950, a worst-case situation in 1961 would be considered and an additional 446 MW would be required to meet system risk.
The unaddressed issue is the tradeoff between the planning horizon and the resources needed. I cannot imagine a business case for the deployment of 446 MW electric system resources that will only be needed once in 63 years. For one thing, the life expectancy of these technologies is much less than 63 years. Even over a shorter horizon such as the last ten years, how will a required facility be able to stay solvent when it runs so rarely? Any reliability mandate that requires consideration of the worst-case lull over an extended period of record like this example is going to be expensive. Consequently, there will be pressure to choose a less restrictive reliability standard even though that means that when the conditions that cause the worst-case lull inevitably occur there will be major problems.
This risk goes away if nuclear resources are used as the backbone of the future electric system. Given the magnitude of the potential problems when renewable resources are unable to provide reliable power for the extreme weather case, this is a major reason to rely on nuclear power for a zero-emissions electric grid. The Staff Proposal presumes that an electric system reliant on wind, solar, and energy storage will somehow work and ignores the reliability risk described here. DPS staff should address this feasibility issue as soon as possible.
Ambiguities in PSL §66-p(2)
I have long argued that implementation of the Climate Act has ignored the safety valve provisions in §66-p (4). That section of the law states: “The commission may temporarily suspend or modify the obligations under such program provided that the commission, after conducting a hearing as provided in section twenty of this chapter, makes a finding that the program impedes the provision of safe and adequate electric service; the program is likely to impair existing obligations and agreements; and/or that there is a significant increase in arrears or service disconnections that the commission determines is related to the program.” I believe that the zero emissions resource could be a primary driver of concerns related to the reliability and affordability provisions of § 66-p (4) so it is incumbent upon DPS to address these considerations quickly. The criteria used to define “safe and adequate electric service” and “significant increase in arrears or service disconnections” must be established to meet this provision.
It is encouraging that DPS Staff recognize that the definition of some of these terms is appropriate. The Staff Proposal states:
Staff finds that the Commission’s authority under PSL §66-p(2) to design a program to achieve the 2040 target is ambiguous in several respects. In particular, Staff believes that clarification is needed to determine how and when the Commission should “consider and where applicable formulate the program to address impacts of the program on safe and adequate electric service in the state under reasonably foreseeable conditions,” as called for by the legislature. While this proposal does not examine this issue, Staff finds that continued proactive evaluation and comparative analysis of potential technologies will play a beneficial role in informing the implementation of PSL §66-p(2).
I agree that the Commission should address impacts of the program on safe and adequate electric service. It is recognition of the need to address the safety valve provisions. However, acknowledging that there is an issue and claiming that “continued proactive evaluation and comparative analysis of potential technologies will play a beneficial role” fails to adequately address this issue. The bottom line is that making progress is a moot point when there are no criteria for checking progress relative to safe and adequate service. New York could be headed down a policy path that does not provide safe and adequate service, but we cannot make that judgement without established criteria. The Commission should have addressed the concerns raised by the legislature long ago and further delays are unconscionable.
Conclusion
The implementation planning for the zero-emission electric grid of 2040 is inadequate to protect the mandated provisions for “safe and adequate” electric service. The Commission acknowledges that a new dispatchable and emissions free resource is needed for the projected gap between wind, solar, and energy storage resource production and expected load during periods of extended low renewable resource availability. However, the Commission has not done a comprehensive analysis to determine the magnitude and duration of the expected gap or the feasibility of potential gap backup resources.
Staff also recommends that “the Commission direct Staff to develop a review process consistent with the provisions of PSL §66-p that tracks progress toward the power sector energy transition targets. While the Staff Proposal acknowledges that the acceptability criteria for safe and adequate electric service resources must be defined, it does not fully address this issue. These are fundamental planning requirements that remain unresolved 22 months after the completion of the Scoping Plan. This should be a priority.
I am convinced that the proposed wind, solar, and energy storage approach will not be able to meet any reasonable acceptability criteria. The longer the delay in developing the criteria and comparing them to the wind, solar, and energy storage strategy, the more investments will be made in an approach that has never worked in any jurisdiction. There is no reason to expect it to work in New York. The Hochul Administration must prove it is possible with a feasibility study or better a demonstration project before continuing with this approach.
The Commission acknowledges that a new DEFR technology is needed to provide backup to wind and solar resources during extended periods of low availability. I believe that nuclear power is the only viable DEFR technology. However, using nuclear only as backup to wind and solar is inefficient and not cost effective. Given the inherent advantages of nuclear over wind and solar the obvious conclusion is that we should stop supporting wind and solar and embrace nuclear as the future backbone of the grid.
