The New York City Housing Authority (NYCHA), New York Power Authority (NYPA) and New York State Energy Research and Development Authority (NYSERDA) on Dec. 20 launched an industry competition directed at heating and cooling equipment manufacturers to develop a new electrification product that can better serve the needs of existing multifamily buildings.
“By leveraging NYCHA’s building portfolio, the Clean Heat for All Challenge is designed to spur innovation by positioning the Authority as an early adopter of this technology, providing public housing residents with access to clean sources of energy through engagement with service providers and manufacturers of heat pump technologies,” NYPA said.
The challenge calls upon manufacturers to develop a packaged cold climate heat pump that can be installed through an existing window opening to provide heating and cooling on a room-by-room basis.
The envisioned product would enable rapid, low-cost electrification of multifamily buildings by reducing or eliminating many of the cost drivers inherent to existing heat pump technologies when used in resident occupied apartments. These include costly electrical upgrades, long refrigerant pipe runs, drilling through walls and floors and other construction aspects which result in high project costs, and significant disruption to residents.
NYCHA, NYPA, and NYSERDA have also engaged with the Consortium of Energy Efficiency to engage manufacturers and encourage broad industry participation in the Clean Heat for All Challenge.
The request for proposals issued by NYPA identifies a list of product specifications that manufacturers will be challenged to meet.
To incentivize participation, NYCHA will commit to purchasing the first 24,000 units from the awarded vendor or vendors that will be installed at six developments currently slated for heating plant replacement over the next five years.
NYSERDA is supporting the effort by providing additional funding from the Regional Greenhouse Gas Initiative operating plan, which calls for the electrification of heating in New York City public housing to improve energy performance, decrease emissions, and improve resident comfort. NYSERDA will provide assistance drafting the product specifications and performing commissioning as well as measurement and verification for the demonstration units.
NYCHA will invest $250 million, in addition to the NYSERDA grant, to purchase and install the new equipment as well as provide additional improvements to the building envelopes and hot water systems.
The initiative is based on a similar product challenge that NYCHA and NYPA partnered on in the 1990s and which produced some of the first Energy Star rated refrigerators, reducing the energy use of refrigerators by over 50 percent.
If the technology developed from the Clean Heat for All Challenge is successful, NYCHA will deploy at more than 50,000 apartments over the next 10 years, to meet space heating and cooling needs with zero on-site emissions.
The type of solutions this initiative is seeking will be broadly applicable to the multifamily sector across the Northeast, NYPA said.
The New York City Department of Housing Preservation and Development and New York State Homes and Community Renewal have already confirmed their strong interest in utilizing this new type of product for their preservation and new construction pipelines.
In addition, NYCHA and NYSERDA are working together with other large public housing authorities and housing agencies in the U.S. and Canada to aggregate a larger potential demand.
These new type of heat pumps will also be applicable for net zero carbon retrofits under NYSERDA’s RetrofitNY initiative. Through the RetrofitNY Pledge, building owners have already pledged to install cost effective net-zero carbon retrofit solutions in over 400,000 dwelling units when they become available.
NYCHA and NYPA are also partnering to replace the aging gas-and-oil-fueled heating and hot water systems at a 20-story high-rise in Manhattan, with a high-efficient electric Variable Flow Refrigerant (VRF) heat pump system.
The $28 million design-build electrification project will eliminate the use of on-site fossil fuel for heating and hot water while also providing central heating and cooling to 100 percent of apartments, replacing the old, inefficient window air conditioning units that have come to define many New York City-based facades. Once complete, residents will be able to individually control the temperature in each room of their apartment.
NYCHA has been an energy customer of NYPA since 1996, partnering to complete $211 million in energy efficiency projects, saving $23 million annually and reducing greenhouse gas emissions by 75,000 tons a year.
Texas Utility Regulators Approve Reforms To Wholesale Electricity Market

The Public Utility Commission of Texas (PUCT) on Dec. 16 voted to enact major reforms to the state’s wholesale electricity market.
Some changes will take effect very quickly to be in place this winter, the PUCT said, while other changes “will provide long-term incentives for investment in reliable power generation infrastructure to ensure Texas will have the power the state needs for decades.”
Key Changes
The changes approved by the PUCT will provide earlier price signals to bring additional generation online and for large consumers to adjust their demand, it said.
The PUCT said its approved reforms increase the market incentives for large consumers to decrease electricity usage in response to prices and grid conditions. This includes virtual power plants where groups of customers can come together into a single resource for the grid.
Emergency Response Service (ERS) is an existing program for large customers to register with ERCOT to decrease their electricity demand when the grid needs additional power. Previously, this tool was only available during an emergency. Now ERS can be used to avoid emergency conditions.
The commission also approved new or revamped ancillary services that include paying generators for having onsite fuel storage, for the ability to respond quickly to changes in the frequency of the grid, and for the capacity to react to abrupt swings in electricity supply and demand.
These improvements are part of Phase 1 of the Commission’s work to improve grid reliability and the wholesale electricity market. Phase 2 will include a review of a backstop reliability service and a load-side reliability mechanism.
These will provide further market signals for reliable generation, the PUCT said.
PUCT staff and Electric Reliability Council of Texas staff will develop phase 2 policies over the coming weeks and report back to the commissioners.
U.S. Power Sector’s Use Of Water Continued Downward Trend
December 20, 2021

December 20, 2021
The U.S. electric power sector’s cooling water withdrawals fell 10.5% from 53.1 trillion gallons in 2019 to 47.5 trillion gallons in 2020, continuing the downward trend in withdrawals, the U.S. Energy Information Administration (EIA) reported on Dec.17.
The decline has been driven by the increased use of renewable and natural gas-fired generation in place of coal-fired generation, as well as less use of once-through cooling technologies, EIA noted.
As the fuel mix has shifted to less water-intensive energy sources, the water intensity of U.S. power generation — the average amount of water withdrawn per unit of electricity generated — has declined from 14,928 gallons per megawatt hour (gal/MWh) in 2015 to 11,857 gal/MWh in 2020, EIA said.
It noted that thermoelectric power plants — including coal, nuclear, and natural gas plants — boil water to create steam, which then spins a turbine to generate electricity. Cooling water is passed through the steam leaving the turbine to cool and condense the steam. This step reduces the steam’s exit pressure and recaptures its heat, which is then used to preheat fluid entering the boiler.
According to EIA, U.S. thermoelectric plants are the largest source of U.S. water withdrawals, accounting for more than 40% of total U.S. water withdrawals in 2015.
The changing U.S. electricity generation mix accounts for approximately 80% of the downward trend in water withdrawals by the electric power sector.
EIA noted that natural gas-fired generation uses a more energy-efficient technology to produce electricity than coal and has a lower water withdrawal intensity than coal. Natural gas combined-cycle generation had an average water withdrawal intensity of 2,793 gal/MWh in 2020, compared with 21,406 gal/MWh for coal.
The share of renewable generation, which on average has a very low water withdrawal intensity, also significantly increased from 2015 to 2020.
The remaining 20% of water withdrawal reductions came from the reduced use of once-through cooling systems.
FERC Seeks Comment On Recovery, Reporting Of Industry Dues, Expenses
December 20, 2021

December 20, 2021
The Federal Energy Regulatory Commission (FERC) has issued a Notice of Inquiry (NOI) to examine the rate recovery, reporting and accounting treatment of industry association dues and certain civic, political and related expenses, as well as whether additional transparency is needed with respect to defining donations for charitable, social or community welfare purposes.
The Commission also is requesting comments on whether any changes are necessary to ensure those expenditures are properly accounted for and recovered in rates regulated by FERC.
FERC’s NOI seeks comment on 22 questions focused in three areas:
- Delineation of recoverable and non-recoverable industry association dues by member utilities for rate purposes;
- Increased transparency in industry association expenses and segments of industry association dues charged to utilities as well as utilities’ and industry associations’ expenses from civic, political and related activities; and
- A framework for guidance should the Commission determine action is necessary to further define the recoverability of industry association dues charged to utilities and/or utilities’ expenses from civic, political and related activities.
FERC generally allows utilities to recover a portion of their industry association dues, but certain expenses, such as the portion of dues relating to industry association lobbying, are generally supposed to be excluded from the costs passed on to customers.
The NOI explains that FERC does not have a “bright-line rule” delineating between recoverable expenses and those excluded from rate recovery. Instead, FERC allows regulated entities to determine the portion of their industry association dues to include in recoverable accounts, based on information provided by the industry associations about their activities and associated costs. Currently, the Commission generally considers the appropriate delineation between the two classes of expenses on a case-by-case basis, determined based on the facts presented.
Initial comments on the NOI are due 60 days after the date of publication of the NOI in the Federal Register. Reply comments are due 90 days after the date of publication in the Federal Register.
APPA, Other Groups Seek FCC Rulemaking for 6 GHz Low Power Indoor Devices
December 20, 2021

December 20, 2021
The American Public Power Association (APPA) and a coalition of critical infrastructure industries on Dec. 7 asked the Federal Communications Commission (FCC) to adopt a rulemaking that develops new rules for 6 GHz low-power indoor (LPI) devices.
While seeking a new rule, APPA and the other industry groups also sought an immediate stay of equipment authorization of unlicensed 6 GHz LPI devices. The stay, pending development of rules that are proven to avoid interference from these devices, will prevent harm to currently licensed microwave systems in the 6 GHz band.
Background
The FCC’s Report and Order (R&O) to open the 6 GHz band of spectrum to unlicensed usage went into effect in July 2020.
The R&O allows two types of unlicensed operations — low powered indoor use and outdoor use protected with an automated frequency coordination (AFC) technology.
A broad coalition of incumbent license holders filed extensive comments raising concerns about interference to operations that could result from opening the band to unlicensed users and requesting further testing and protections from the FCC. Those concerns and comments were not addressed, leading APPA and others in the electric sector to file legal challenges.
In April 2021, investor-owned utility Southern Company and the Electric Power Research Institute (EPRI) acquired 6 GHz devices available on the market to conduct real world testing on impacts to electric utilities.
They operated them near a Southern Company microwave link operating between Fortson and Columbus, Ga., using the FCC thresholds for reportable interference. The tests showed that, even at low powered indoor use, the unlicensed devices would “cause harmful interference to licensed fixed microwave systems” greater than the FCC’s acceptable levels. This report was filed and presented to FCC staff.
Petition For Rulemaking
The petition for rulemaking states that the current rules for LPI use are flawed because they rely on modeling and not real-world data and, as such, must be modified to protect incumbent license holders from harmful interference.
The petition further states that LPI devices should be controlled by an AFC system, the FCC should adopt rules for licensees to recover costs from monitoring and mitigating potential interference created by unlicensed systems, and the FCC should conduct independent testing to determine if new rules should be developed for standard power devices.
“Recent real-world tests have determined that 6 GHz LPI devices will cause harmful interference to licensed microwave systems in the band, due in part to beacon signals that will transmit constantly and thus endanger the functioning of services to public safety and critical infrastructure industries and seriously degrade, obstruct, or repeatedly interrupt their radio communications services,” the groups said.
“These tests also demonstrate that the data and the assumptions for the Commission’s rules for 6 GHz LPI devices are fundamentally flawed.”
The FCC should therefore exercise its rulemaking authority “to revise the rules and conduct open and transparent testing to prove these rules effectively prevent interference to licensed microwave systems. In that regard, the Commission should require 6 GHz LPI devices to be controlled by AFC or use some other interference protection mechanism.”
The groups also said that the FCC should establish a mechanism for cost recovery by incumbents to reimburse them for mitigating and resolving interference from unlicensed 6 GHz operations.
They said that this is consistent with the Commission’s emerging technologies framework and Commission precedent.
“Also, due to the flawed data and assumptions upon which the Commission relied, the Commission should conduct independent tests of standard power access devices to determine if new rules need to be developed that will prevent interference from these devices to licensed microwave systems in the band.”
Request For Stay
The request for stay asks the FCC to put a temporary halt on the equipment authorization of unlicensed 6 GHz LPI devices pending the adoption of rules that are proven to prevent interference to licensed systems.
The stay is necessary to prevent the imminent risk of irreparable harm from the interference that these unlicensed 6 GHz LPI devices are certain to cause to incumbent licensed systems in the band, such as electric utility SCADA and other system monitoring equipment.
A temporary stay will not significantly harm the interests of other stakeholders, “and the public interest favors granting the stay immediately to protect public safety and critical infrastructure industries who provide essential services to the public at large” the petitioners stated.

- American Gas Association
- Edison Electric Institute
- American Petroleum Institute

FERC Aims To Improve Accuracy, Transparency Of Transmission Line Ratings
December 20, 2021
by Paul Ciampoli
APPA News Director
December 20, 2021
The Federal Energy Regulatory Commission (FERC) on Dec. 16 issued a final rule that reforms FERC’s pro forma open access transmission tariff (OATT), as well as the Commission’s regulations in an effort to improve the accuracy and transparency of electric transmission line ratings.
Transmission line ratings represent the maximum transfer capability of each transmission line.
Staff at FERC noted in a presentation given at the Commission’s monthly open meeting that transmission line ratings are often based on conservative assumptions about the worst-case, long-term air temperature and other weather conditions.
Temperature and weather conditions vary day-to-day and hour-by-hour, but seasonal or static ratings are typically updated only when equipment is changed or weather assumptions are revised. Therefore, the line ratings may not accurately reflect the near-term transfer capability of the system.
FERC staff said that more accurate ratings can be achieved through the use of ambient-adjusted ratings (AARs) and dynamic line ratings (DLRs), both of which are the subject of the final rule.
Unlike static ratings, which are calculated annually or seasonally, ambient-adjusted ratings are determined using near-term forecasted ambient air temperatures and updated day/night solar heating values, FERC staff said.
Dynamic line ratings are calculated using up-to-date forecasts of ambient air temperature, plus other weather conditions such as wind, cloud cover, solar heating intensity, and precipitation, in addition to transmission line conditions such as tension or sag.
What The Final Rule Calls For
The final rule identifies numerous consequences to using an inaccurate representation of system transfer capability.
For example, because ambient air temperatures are nearly always less extreme than worst case assumptions, seasonal and static transmission line ratings often result in less available transmission system transfer capability than the transmission system can actually provide during many hours of the year. This increases congestion costs and causes costly curtailment, interruption, and redispatch decisions, according to FERC.
At other times, however, seasonal or static transmission line ratings may overstate the near-term transfer capability of the system, creating potential reliability problems and inaccurately low congestion pricing.
In either case, the use of seasonal and static assumptions results in transmission line ratings that do not accurately represent the transfer capability of the transmission system.
To address this concern, the final rule adopts a number of new requirements:
- The final rule requires the implementation of ambient-adjusted ratings and seasonal ratings. Transmission providers would use AARs for evaluating requests for near-term transmission service (defined as transmission service that ends within 10 days of the date of the request), and would use seasonal ratings for evaluating other, longer-term transmission service requests. The final rule requires implementation of ambient-adjusted ratings for all lines that are impacted by air temperatures and requires implementation within three years of utility compliance filings required to be submitted under the rule.
- The final rule requires regional transmission organizations (RTOs) and independent system operators (ISOs) to establish and implement the systems and procedures necessary to allow transmission owners to electronically update transmission line ratings at least hourly. The final rule recognizes that there may be instances in which transmission owners may wish to implement transmission line ratings that may be even more accurate than ambient-adjusted ratings, such as dynamic line ratings, but are unable to have such ratings reflected in RTO/ISO markets under those markets’ current capabilities. The final rule would remove this barrier to use of these more accurate line ratings.
- Third, the final rule requires transmission providers to use uniquely determined emergency ratings for contingency analysis in the operations horizon and in post-contingency simulations of constraints.
In an effort to boost transparency, the final rule requires transmission owners to share transmission line ratings and transmission line rating methodologies with their respective transmission providers and, in RTOs/ISOs, with their respective market monitors.
The draft final rule also requires transmission providers to maintain a database of each transmission owner’s transmission line ratings and transmission line rating methodologies on the transmission provider’s Open Access Same-Time Information System site, or on another password-protected website. Such information sharing would increase situational awareness and improve the ability to verify the accuracy of transmission line ratings, FERC concluded.
In addition, the draft final rule states that the Commission will continue to explore the implementation of dynamic line ratings in a new docket.
Compliance filings are due 120 days after publication in the Federal Register.
Secretary of Energy Visits SMUD Battery Storage Site, Training Facility

Secretary of Energy Jennifer Granholm on Dec. 17 visited a Sacramento Municipal Utility District (SMUD) solar farm and battery storage facility in south Sacramento, Calif., as well as a SMUD facility that trains people to become highly skilled utility professionals.
Granholm was joined in her visit to the SMUD Power Academy by U.S. Rep. Ami Bera, D-Calif., and SMUD CEO and General Manager Paul Lau.
Each year, the training facility produces 500 skilled trade professionals through 12 apprenticeship programs, supporting regional workforce development opportunities.
Granholm also toured SMUD’s Hedge solar farm and battery energy storage facility, along with Lau and Rep. Bera.
The energy storage units are part of SMUD’s first utility-scale battery energy storage project — and a major element in its 2030 Zero Carbon Plan.
The six units, which weigh about 52,000 pounds each, are part of a SMUD Energy Strategy, Research & Development department project that also includes a myriad of other SMUD employees from throughout the organization.
Combined, the lithium-ion batteries will generate 4 megawatts of electricity and store 8 megawatt hours of energy, which is enough to power 800 homes for 2 hours. Inside each of the 6 units are 3,840 battery cells stacked and connected together.
They will soon be fully operation, but SMUD will continue to gather and research data. SMUD will learn about the feasibility of utility-scale battery storage and the practicality of reserve power at a large scale for future grid integration into SMUD’s Battery Energy Storage System, known as BESS.
According to SMUD, Granholm spoke about the criticality of achieving a clean energy future and the need for workers that can build the grid of the future, bringing good paying jobs.
She praised SMUD’s leadership for setting an example for the nation to follow in both setting such an ambitious goal to achieve zero carbon by 2030 and in training the utility workers of the future through the Power Academy, SMUD noted.
Granholm said that SMUD’s example “of how we can get” to clean, dispatchable baseload power “is what we want to take across the nation.”
She also said that “if we want to build out all of this clean electricity, we have to build out transmission for that clean electricity. That means we’re going to need the workers to be able to build that out.” The example being set by SMUD “is to create good jobs for people to be able to install the kinds of technologies” including the transmission grid.
“It was an honor to give U.S. Energy Secretary Granholm and Congressman Bera a tour of SMUD’s Hedge solar farm and battery energy storage facility and the adjacent Sacramento Power Academy,” Lau said.
He thanked Secretary Granholm for recognizing SMUD’s clean energy leadership.
“We’re proud and excited to be pursuing the boldest clean energy goal of any large utility in the country — to remove 100% of all carbon emissions from our power supply by 2030. The Secretary and I agree, we have to act with urgency to address the impact of climate change and create a clean energy future for all. And to get there, we’ll need skilled utility workers in good-paying jobs,” Lau said.
“That’s why inclusive workforce development is a key part of our Zero Carbon Plan. Sacramento’s Power Academy is training people to build and maintain the grid our clean energy future needs and will create good-paying jobs,” he said.
Lau discussed SMUD’s zero carbon plan in an episode of the American Public Power Association’s Public Power Now podcast earlier this year.

At an Owensboro Utility Commission meeting on Dec. 16, Owensboro Municipal Utilities (OMU) General Manager Kevin Frizzell advised the Commission that he intends to retire effective Aug. 1, 2022.
Frizzell told the Commission he was making the announcement now so to provide ample time for the selection of a new General Manager and to ensure a smooth transition for the Kentucky utility.
Frizzell, who will have 32 years of service upon his retirement has served as General Manager for the past four years.
Frizzell was named interim General Manager on Feb. 12, 2018 and General Manager on December 20, 2018.
Frizzell, formerly OMU’s Director of Production, joined OMU in 1990 at the company’s coal-fired generating plant, the Elmer Smith Station, as the Technical Services Manager.
He was named Director of Power Production in 2008, charged with the management of OMU’s largest asset, the Elmer Smith Station. In 2013, OMU combined power production and water treatment into one production department and operation of OMU’s two drinking water plants came under his area of responsibility.
Utility Commission Chairman JT Fulkerson said that OMU is ready to begin the search and selection process and expects to identify qualified candidates from outside and within OMU.
OMU is the largest municipal electric and water system in Kentucky with more than 26,000 electric, 24,000 water and 160 telecommunications customers.
New York Governor Unveils Framework For State To Achieve At Least 10 GW of Distributed Solar

December 19, 2021
New York Gov. Kathy Hochul on Dec. 17 unveiled a framework for the state to achieve at least 10 gigawatts (GW) of distributed solar by 2030.
The roadmap was submitted by the New York State Energy Research and Development Authority (NYSERDA) and the New York State Department of Public Service (DPS) to the New York Public Service Commission for public comment and approval.
The announcement supports the state’s Climate Leadership and Community Protection Act mandate to generate 70 percent of the state’s electricity from renewables by 2030.
The roadmap proposes a comprehensive strategy to expand the state’s NY-Sun initiative into one of the largest and most inclusive solar programs of its kind in the nation.
NYSERDA and DPS evaluated multiple strategies to deploy 10 GW or more of distributed solar — projects that are under five megawatts (MW) in size, including rooftop installations and community solar projects — by 2030 and determined that extending the NY-Sun initiative provides the most efficient, familiar, and cost-effective path forward.
The roadmap proposes at least 1,600 MW of new solar capacity to benefit disadvantaged communities and low-to-moderate income New Yorkers, with an estimated $600 million in investments serving these communities.
It also proposes at least 560 MW to be advanced through the Long Island Power Authority and at least 450 MW to be built in the Con Edison electric service area.
The roadmap is available for public comment on the DPS website and subsequent decision-making in 2022.
Since the NY-Sun initiative was launched, NYSERDA has worked closely with local governments, agricultural communities, other state agencies, and a wide range of stakeholders to ensure that projects are developed and sited in a manner that fully considers land use and are advanced in close collaboration with local stakeholders and agricultural communities.
NYSERDA will extend its ongoing technical assistance for all municipalities in the state to assist localities in aligning solar development with local priorities.
California Community Choice Aggregator Earns “A” Credit Rating From S&P

December 19, 2021
California community choice aggregator (CCA) East Bay Community Energy (EBCE) has been given an “A” issuer credit rating from S&P Global Ratings.
S&P cited EBCE’s solid financial performance. At fiscal year-end 2021, EBCE had no debt outstanding.
The rating agency also said that EBCE’s environmental risk exposure is low, based on its predominantly carbon-free resource portfolio.
The outlook is stable.
“The credit rating is important for two reasons,” said EBCE CEO Nick Chaset. “For EBCE’s counterparties, such as renewable energy project developers, it shows that we’re on solid financial footing and are low risk, which can help us secure the best terms in our contracts. This translates to better access and service of low-cost, long-term renewable energy for EBCE customers in the decades to come.”
EBCE operates a community choice energy program for Alameda County, Calif., and fourteen incorporated cities, serving more than 1.7 million residential and commercial customers.
EBCE initiated service in June 2018 and expanded to the cities of Pleasanton, Newark, and Tracy in San Joaquin County in April 2021.
The American Public Power Association has initiated a new category of membership for community choice aggregation programs.
