Electricity update Pt. 10
« on: February 25, 2020, 03:30:46 AM »
From Warren Buffett & Berkshire Hathaway.

https://www.berkshirehathaway.com/2019ar/2019ar.pdf


SNIP (page 9):

Berkshire Hathaway Energy is now celebrating its 20th year under our ownership. That anniversary suggests that we should be catching up with the company’s accomplishments.

We’ll start with the topic of electricity rates. When Berkshire entered the utility business in 2000, purchasing 76% of BHE, the company’s residential customers in Iowa paid an average of 8.8 cents per kilowatt-hour (kWh). Prices for residential customers have since risen less than 1% a year, and we have promised that there will be no base rate price increases through 2028. In contrast, here’s what is happening at the other large investor-owned Iowa utility: Last year, the rates it charged its residential customers were 61% higher than BHE’s. Recently, that utility received a rate increase that will widen the gap to 70%.

The extraordinary differential between our rates and theirs is largely the result of our huge accomplishments in converting wind into electricity. In 2021, we expect BHE’s operation to generate about 25.2 million megawatt-hours of electricity (MWh) in Iowa from wind turbines that it both owns and operates. That output will totally cover the annual needs of its Iowa customers, which run to about 24.6 million MWh. In other words, our utility will have attained wind self-sufficiency in the state of Iowa.

In still another contrast, that other Iowa utility generates less than 10% of its power from wind. Furthermore, we know of no other investor-owned utility, wherever located, that by 2021 will have achieved a position of wind self-sufficiency. In 2000, BHE was serving an agricultural-based economy; today, three of its five largest customers are high-tech giants. I believe their decisions to site plants in Iowa were in part based upon BHE’s ability to deliver renewable, low-cost energy.

Of course, wind is intermittent, and our blades in Iowa turn only part of the time. In certain periods, when the air is still, we look to our non-wind generating capacity to secure the electricity we need. At opposite times, we sell the excess power that wind provides us to other utilities, serving them through what’s called “the grid.” The power we sell them supplants their need for a carbon resource – coal, say, or natural gas.

Presuming wind if price competitive, and nearly everything I see says it is, the shift will happen through normal market forces, perhaps not as fast as Bernie et al. would like.

Iowa seems ideal for wind.  They can back it up with NG and hopefully end using coal.

https://www.pv-tech.org/news/indiana-utility-to-replace-coal-with-solar-plus-storage-wood-bags-virginia

SNIP:
Vectren, owner of utility firms in the US states of Indiana and Ohio, has unveiled plans to ditch more than 700MW of coal generation and partly replace it with up to 1GW of solar PV.

And those plans, detailed within the utility’s Integrated Resource Plan (IRP), could see new solar arrays paired with battery energy storage in a bid to save consumers served by Vectren up to US$320 million over the next 20 years.


On top of saving consumers some US$320 million over the 20-year planning period, the shift in generation will also reduce carbon emissions from Vectren’s operations by nearly 75%.

Joint venture created for Chalk River MMR project​
« Reply #6 on: June 17, 2020, 01:46:19 PM »
A joint venture has been formed between Ultra Safe Nuclear Corporation (USNC) and Ontario Power Generation (OPG) to build, own and operate the proposed Micro Modular Reactor (MMR) project at the Chalk River Laboratories site. The joint venture – the Global First Power Limited Partnership – is owned equally by OPG and USNC-Power, the Canadian subsidiary of USNC.

Ottawa-headquartered Global First Power (GFP), which initiated the project last year, will act on behalf of the Limited Partnership to oversee the proposed MMR project. It will provide project development, licensing, construction and operation of the commercial demonstration reactor at Chalk River.
GFP, USNC and OPG have been collaborating on the Chalk River project for several years, which has led to the joint-ownership arrangement and creation of the Limited Partnership.
"The partnership demonstrates the companies' mutual commitment to making low-carbon, small nuclear reactors a reality for Canada, and a viable alternative to diesel and other fossil fuels," they said in a joint statement yesterday. The Chalk River project, the partners said, "will serve as a model for potential future GFP projects across Canada, to provide safe and sustainable low-carbon power and heat to industries, such as mining, and remote communities."
"The backing of OPG combined with USNC's advanced reactor and fuel designs will allow us to continue to lead the way in delivering a small-reactor solution in Canada," said GFP CEO Joe Howieson. "This joint venture is a very important milestone, marking new levels of commitment by an innovator in nuclear power-generation technologies and a forward-thinking, major utility."
"While there are many small reactor companies boasting about the progress they're making, no other organisation is closer to constructing a micro reactor in Canada than we are," said Francesco Venneri, CEO of USNC. "Through this joint venture, we're committed to proving how viable, safe, and valuable our MMR technology is to Canada and to the rest of the world."
OPG President and CEO Ken Hartwick added: "We are excited about the advancement of low-carbon small modular reactors in Canada and see them as an innovative growth opportunity for our company, one that fits well with our existing clean energy portfolio."
The MMR is a 15 MW thermal, 5 MW electrical high-temperature gas reactor, drawing on operational experience from reactors developed by China, Germany, Japan and the USA. According to World Nuclear Association information, the reactor uses fuel in prismatic graphite blocks and has a sealed transportable core. The reactor completed the first phase of the Canadian Nuclear Safety Commission pre-licensing vendor design review process in January 2019. The MMR project is in the third stage of Canadian Nuclear Laboratories' (CNL's) four-stage process to site a demonstration small modular reactor (SMR) at Chalk River Laboratories. The MMR project is currently undergoing an environmental assessment.
CNL has identified SMRs as one of eight strategic initiatives it is pursuing as part of its long-term strategy, with the goal of siting an SMR by 2026. At present four proponents are engaged in the four-stage invitation process launched in 2018 to evaluate the construction and operation of a demonstration SMR at a CNL site. U-Battery Canada Ltd, with a design for a 4 MWe high-temperature gas reactor; StarCore Nuclear, with a proposed 14 MWe high-temperature gas reactor; and Terrestrial Energy, with a 190 MWe integral molten salt reactor, have all completed the first stage of the process.

Russia starts installation work at fuel fabrication facility
« Reply #7 on: June 20, 2020, 04:50:09 PM »
Work has started on installation of the main equipment for the nuclear fuel fabrication facility (FRU) at the pilot energy complex (ODEK) in Seversk (Tomsk). Under construction at the Siberian Chemical Combine, ODEK is part of Russia’s Proryv (Breakthrough) project, which is designed to demonstrate a closed fuel cycle. SCC is part of fuel company TVEL, which is a subsidiary of state nuclear corporation Rosatom.

The ultimate aim is to eliminate production of radioactive waste from nuclear power generation. The Breakthrough project comprises a fuel production/refabrication module for production of dense uranium-plutonium (nitride) fuel for fast reactors; a nuclear power plant with a BREST reactor; and a used fuel retreatment module.
The first shop-floor prepared for equipment installation is the decontamination section of the fuel rod production line. Currently, there are over 40 items of equipment with a total weight of about 110 tonnes at the FRU site.
"There is no other such equipment anywhere else in the world and, thus, no typical approach for construction of such facilities," Alexander Gusev, SSE deputy director general in charge of the Proryv project, said in a Rosatom statement today. "This project is totally unique, from the drawings to the installation schemes,” he added.
Installation of the main technological equipment is being worked out in advance in digital mode (4D modeling) in order to "minimise any possible mismatches and optimise the sequence of works", Rosatom said.
The installation of equipment at the FRU will take about 18 months. The site of the future 300 MW nuclear power plant, powered by the BREST-OD-300 reactor, is being prepared for the start of construction work.

South Africa starts consultations on nuclear new build
« Reply #9 on: June 22, 2020, 01:54:19 PM »

South Africa's Department of Mineral Resources and Energy (DMRE) has issued a Request for Information (RFI) to enable it to assess nuclear technologies that could be considered for a national programme to build 2500 MWe of new nuclear capacity. The programme could include conventional pressurised water reactors (PWRs), small modular reactors (SMRs) or a blend of technologies.

Publication of the RFI is the start of preparatory work to develop plans for a future nuclear programme, Mineral Resources and Energy Minister Gwede Mantashe said on Twitter. "Given the long lead-time of building additional new nuclear capacity, upfront planning is necessary for security of energy supply to society," he said.
Mantashe said in May the DMRE would start work on a roadmap for nuclear procurement, which is in line with South Africa's 2019 Integrated Resource Plan.
"It is envisaged that the South African Nuclear Power Programme may comprise a blend of baseload power combining both conventional PWR and SMR technologies to a total of 2500 MW at a pace and scale the country can afford," the RFI notes. Owing to the "significant technology and maturity difference" between conventional PWRs and SMRs, participants may comment on more than one technology.
PWR technologies submitted to the RFI should be currently commercially available. SMR technologies are expected to be under development for commercialisation by 2030. Submissions must address aspects including costing and financing; plant design features; licensability of the plant design in South Africa; feasibility of construction at South African sites; a detailed project management plan; and indicative contracting models. Submissions for conventional PWRs should also include options for using the reactor for the desalination of sea water.
Participants in the RFI - which DMRE describes as a stand-alone information-gathering and market-testing exercise only - have until 15 July to register their interest in the RFI.
Two PWRs at Koeberg, operated by state-owned utility Eskom, began commercial operations in the mid-1980s and together generate some 5% of South Africa's electricity.

TVA gives distributors more flexibility to generate their own power
Contract change expected to boost solar, renewable power

SNIP:
For the first time in its 87-year history, the Tennessee Valley Authority is allowing the municipal power utilities and electric cooperatives that distribute TVA electricity to generate up to 5% of their own power to sell directly to their customers.

TVA announced Monday that it is offering a more flexible purchased power agreement to those local power companies such as Chattanooga's EPB that have signed long-term contracts to buy most of their power from TVA. After an environmental assessment and public review this year, TVA said it will now allow its distributors to build their own solar farms or other power generating facilities to help serve part of their power load.


The contract flexibility is expected to spur more solar and other renewable power generation in local communities across TVA's 7-state region, especially if solar panels and wind turbines continue to become more efficient and the power they produce becomes relatively cheaper. EPB, for instance, has budgeted $10 million in the next fiscal year to explore building some of its own solar generation or battery storage under the new contract provision.

The move reflects the growing trend toward smaller, distributed energy generation from solar, wind and other renewable sources located closer to where the power is used rather than the giant, base-load coal or nuclear plants wholesale utilities like TVA have built and operated for decades.

"This is an improvement, but we still believe that TVA unnecessarily limited the ability of local power companies to get the full 5%," said Stephen Smith, executive director for the Southern Alliance for Clean Energy in Knoxville.

Smith said TVA's definition for the 5% limit means that some distributors will be restricted below even 5% of their total sales "and we thought that TVA should give even more flexibility to its distributors if they can better serve their customers.

"TVA needs to be acting in the public good, not for its own benefit," Smith said.

But TVA said the new contract flexibility could allow for between 800 megawatts and 2,000 megawatts of solar or other distributed generation if all 154 local power companies took advantage of the long-term power agreements.

TVA President Jeff Lyash said the contract flexibility is in addition to TVA's Green Invest program in which TVA works with local power companies to supply renewable power to business or university customers wanting to purchase only green power, similar to what Google, Facebook and Vanderbilt University have already done in the Tennessee Valley.

Gabriel Bolas, Knoxville Utilities Board president and CEO, said Knoxville is using the Green Invest program to build its own 212-megawatt solar farm projected to supply about 8% of KUB's annual electric load and the contract flexibility could be added to that share of distributed power.

SNIP:
Earlier this year, the Southwest Power Pool (SPP), the regional transmission organization that manages the electric grid for much of the central United States, set records for the highest share of electricity demand supplied by wind power in both a single-hour period (72%) and a full day (62%).

In 2019, wind power provided 29% of the electricity demand in SPP. On a monthly basis, wind power’s share of total demand in 2019 ranged from a high of 37% in October to a low of 18% in August. On a daily or hourly basis, however, wind’s share can be larger because of fluctuations in wind output and in total electricity generation.

On Saturday, March 7, 2020, the wind penetration rate, expressed as the share of electricity demand supplied by wind generation, reached 62% in SPP. On an hourly basis, wind generated a high share of 72% of electricity demand in the early morning of Monday, April 27, 2020, from 1:00 a.m. to 2:00 a.m. Central time.


Records for wind penetration are often broken in the spring because of seasonal patterns in both electricity demand and wind power output. In the SPP region, wind generation is often highest in the spring months. Spring is also a time of year when electricity demand is relatively low because mild temperatures mean less electricity is used to heat or cool homes. Electricity demand is also relatively lower on weekends, which is when wind set its recent record shares in SPP.

Coal consumption in the US hasn't been this low since the mid-1970s, when GDP and the population (215 million in 1975 vs. 328 million today) were much lower than today....

And coal consumption so far in 2020 is about -34% lower than in 2019 (first three months).  Which would put consumption back to levels last seen in the 1960s.

If "global warming" is a CO2 event, it is not going to be because of the US.  These radicals need to go to Beijing and protest in Tiananmen Square.

April is best for renewables as demand for electricity is low yet wind blows a lot that month.
But it is instructive that 10 states generated more than one-third of their electricity from wind and solar in April....

Iowa           67.1%
Kansas        52.2%
Oklahoma   45.2%
S. Dakota   43.2%
California    40.2%
Vermont     38.9%
N. Dakota   37.9%
Mass.         37.1%
Minnesota   34.8%
N. Mexico   33.9%

As for Solar among states not hitting the 1/3rd threshold:
Hawaii         21.9%
Nevada        20.1%
N. Carolina  10.9%
