Fairchild has launched the world’s first 1000V integrated power switch, offering what it claims is the industry’s highest breakdown voltage in a single package for designing highly reliable switching mode power supplies for smart meter, appliance and industrial systems. The new FSL4110LR switch eliminates the need for external components found in competing solutions, enabling power designers to easily meet their time to market and reduce bill of materials. The company claims: “Fairchild’s new power switch is the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities and is particularly important for smart metering applications” The FSL4110LR integrates a VDMOS SenseFET (BVDSS=1000V) with built in line compensation for wide input voltage range from 45Vac to 460Vac. It also includes built-in input over voltage protection and a safe auto-restart mode for all protection conditions. Fairchild is exhibiting at Electronica 2014 in Munich, Germany from November 11 to 14 in Booth A4.506. “Fairchild’s new power switch is the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities and is particularly important for smart metering applications,” Gaurang Shah, Sr. VP, power systems business group at Fairchild said. “With the world’s highest breakdown voltage, the FSL4110LR is an excellent solution for any designer implementing flyback converters that need to meet three phase input voltage or unstable single phase input voltage requirements.”

Atomenergoproekt has installed the reactor containment building dome at unit 2 of the city of Novovoronezh' No 2 nuclear power plant. Novovoronezh II is the lead project for the deployment of the AES-2006 design incorporating a Gidropress-designed pressurised water reactor, an evolutionary development from the VVER-1000. Construction of Novovoronezh II units 1 and 2 began in June 2008 and July 2009, respectively. The original Novovoronezh site nearby already hosts three operating reactors and two that are being decommissioned. The new units will have a passive heat removal system that, in the event of loss of on-site power supply, will provide long-term heat removal from the reactor core to the atmosphere using natural circulation.

The Electric Reliability Council of Texas anticipates implementation of the US Environmental Protection Agency’s proposed rule for reducing greenhouse gas emissions will result in the retirement of up half of ERCOT’s coal generation capacity, raise retail energy bills up to 20% and lead to a greater likelihood of rotating outages.

ERCOT Monday released its analysis of the impact of the Clean Power Plan, saying it “is evident that implementation ... will have a significant impact on the planning and operation of the ERCOT grid.”

“ERCOT's primary concern with the Clean Power Plan is that, given the ERCOT region’s market design and existing transmission infrastructure, the timing and scale of the expected changes needed to reach the CO2 emission goals could have a harmful impact on reliability,” according to the report.

“ ... it is unknown, based on the information currently available, whether compliance with the proposed rule can be achieved within applicable reliability criteria and with the current market design.”

EPA released in June proposed rules on limiting greenhouse gas emissions, calling for reductions equivalent to 30% from 2005 emissions levels by 2030.

The proposed Clean Power Plan provides state-by-state interim CO2 reduction goals to be achieved by 2020 and final goals to be accomplished by 2030.

For Texas, EPA has proposed an interim goal of 853lb CO2/MWh to be met on average during 2020-2029, and a final goal of 791lb CO2/MWh to be met from 2030 onward.

A decrease to the ERCOT reserve margin is a major concern stemming from the rule because it would lead to a greater likelihood of having to resort to rotating blackouts, said Warren Lasher, ERCOT’s director of system planning.

ERCOT has initiated rotating outages four times in its history: The first in 1989 and the latest in October.

Other concerns include the need for significant upgrades to the transmission system, significant buildout of renewables and the cost of new transmission lines, Lasher said.

According to ERCOT’s analysis, the proposed CO2 emissions limitations will result in the retirement of up to 8700MW of coal generation capacity, which could result in transmission reliability issues from the loss of generation resources in and around major urban centers. It also will strain ERCOT’s ability to integrate new intermittent renewable generation resources.

“In the next five to seven years, ERCOT is likely to lose up to half of its coal generation capacity,” Lasher said.

The retirement of coal resources will require reliability studies to determine if there are any voltage/reactive power-control issues that can only be mitigated by those resources; how to replace frequency response, inertial support, and ramping capability provided by retiring units; and the necessity of potential transmission upgrades, ERCOT stated in the report.

The generation from retiring coal capacity will mostly be replaced by increased production from existing natural gas capacity, according to ERCOT’s report.

While ERCOT is not affected by natural gas supply issues, the increased use of natural gas nationally could cause increased market dislocations, such as seen last winter.

Consumers will eventually bore all of these costs on their energy bills, Lasher said, adding 2020 retail energy bills are expected to increase as much as 20%.

The issues involved with implementation of the plan highlight the need for the final rule ~ due to be released in June ~ to include a process to effectively manage electric system reliability issues that may arise due to implementation, as well as include more implementation timeline flexibility to address each state’s or region’s unique market characteristics, according to ERCOT’s report.

“With respect to the need to manage reliability issues, ERCOT supports the [independent system operator/regional transmission operator] Council proposal for the inclusion of a reliability safety valve process in the context of the CO2 rule, as well the need for states to consult with ISOs/RTOs during the development of state plans,” ERCOT stated.

ERCOT will release a more comprehensive report December 16 to present its analysis of several proposed or recently finalized environmental regulations that could affect future generation resources in the ERCOT region.

Mercom Capital Group, llc, a global clean energy communications and consulting firm, released its report today (16/10/2014) on third quarter funding and mergers and acquisitions activity for the solar sector in 2014. Total global corporate funding in the solar sector, including venture capital, private equity, debt financing, and public market financing raised by public companies, jumped to $9.8bln, compared to $6.3bln in the second quarter of 2014. This quarter also saw the third yield Initial Public Offering so far this year, the $577m float of TerraForm Power, a subsidiary of SunEdison. Raj Prabhu, CEO of Mercom Capital Group, commented: “financing activity was strong all around this quarter whether you look at VC, debt or public markets and it was the best fundraising quarter since tghe first quarter 2011. Venture capital funding in solar has now crossed $1bln in the first three quarters this year.” Global veture capital and private equity funding, in the third 2014 totaled $326m in 21 deals, down from $452m in 22 deals in the second quarter 2014. Like the previous quarter, solar downstream companies attracted most of the venture capital funding in Q3, with $205m in 11 deals.

Japan's regional power monopolies consumed 3.7% less liquefied natural gas (LNG) in October than a year earlier to generate electricity, industry data showed on Friday. The utilities burned 4.45m tonnes of LNG equivalent last month compared with 4.62m tonnes a year earlier, data from the Federation of Electric Power Companies of Japan showed. Despite the slight decline, gas and coal consumptions were at high levels due to the complete shutdown of nuclear plants following the massive quake in 2011. They generated 68.86bln kilowatt-hours of electricity in October, down 3.6% from a year earlier as mild hotness in early part of the month reduced cooling demand, marking the seventh straight month of declines.
