On 19 October 2023, the Federal Energy Regulatory Commission (FERC) issued a final rule directing the North American Reliability Corporation (NERC) to develop new or modified reliability standards to tackle the issue of grid reliability gaps relating to inverter-based resources (IBRs). 1 The reliability standards will impact wind and solar renewables, as well as battery storage. [pdf]
This Standard specifies the electrical installation requirements for inverter energy systems and grid protection devices with ratings up to 10 kVA for single-phase units, or up to 30 kVA for three-phase units, for the injection of electric power through an electrical installation to the electricity distribution network.
As required by Order No. 901, NERC will file reliability standards in three phases through late 2026. Energy storage resources are undoubtedly versatile assets that can play a number of different roles on the grid, including to support transmission reliability.
As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards ” [1, p. 30].
Table 3.1. Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.
FERC also gave NERC flexibility to “propose to develop new or modified Reliability Standards that address [FERC’s] concerns in an equally efficient and effective manner,” but in that case, NERC must “explain how the new or modified Reliability Standards address the Commission’s concerns” discussed in Order No. 901. 11
Discussions with industry professionals indicate a significant need for standards ” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.

The Pongae-6 is a North Korean two-stage surface-to-air missile that was first test launched on September 30, 2021. The system was first shown in the 75th anniversary of the Workers' Party of Korea parade, where it was possibly confused with a long-range cruise missile system.

North Korea has produced and deployed relatively modern man-portable air defense systems (MANPADS) that are intended to engage both aircraft and small, low-altitude targets such as cruise missiles and a large number of towed and self-propelled anti-aircraft guns.
Although the modernization of North Korea’s air defense network, which for decades has been among the world’s densest, is well underway, along with the expansion of its strike capabilities aimed at enemy airfields, the obsolescence of its fighter fleet—even by the standards two decades ago—remains a major outstanding shortcoming.
The appearance of such missiles at a major arms exhibition in 2021 confirmed longstanding speculation that such programs could be the next step for North Korea’s defense sector, with these assets having the potential to revolutionize the fighter fleet’s capabilities. Background: North Korea’s Defense Sector After the Cold War
The most comprehensive short-range air defense suite in North Korea to date could be found onboard a new class of naval corvettes that was revealed by state media in August 2023.
While much remains unknown about North Korea’s missile guidance technologies, the capabilities demonstrated by its surface-to-air missiles indicate that the country can likely produce guidance systems for an AAM decades ahead of those of the AAMs it acquired from the Soviet Union in terms of sophistication.
What is possible, however, is that North Korea will seek to leverage its investments in anti-aircraft missile technologies from its new air defense systems to develop air-to-air missiles (AAMs) for its existing aircraft.

The upcoming RE+ 2023, North America’s largest renewable energy event, also addressed ESS as a core technology of the electricity market. While many Korean companies specialize in batteries, ACE Engineering will take part in the event as an expert in ESS.
While companies have faced new challenges, energy storage systems have emerged as a key solution in the electricity industry. An ESS is a device that stores surplus generated electricity in batteries and disburses it when needed. Amid bolstered demand for green energy, the size of the ESS market is expected to skyrocket by 2030, the company added.
Immersion Cooling ESS Safety Test: A thermal runaway is induced in the lithium-ion battery module to trigger a fire. The cooling fluid, fully immersed, effectively prevents its spread Hanwha Aerospace Founded in 1977, Hanwha Aerospace has become a leading company in the aerospace industry in South Korea.
The newly developed immersion cooling ESS uses advanced thermal fluid technology to fill the lithium-ion battery modules, effectively isolating each cell.
SNE Research According to market researcher SNE Research on March 11, by region, demand for ESS was highest in China (84 GWh), accounting for 45% of the total market share. North America (55 GWh) accounted for 30%, while Europe and other regions each recorded 25 GWh, holding a 12% market share.
