Baseload power and meeting its demands

Renewable energy is considered to be the main source of the baseload power. Some do believe this idea but the others do not. It is because the renewable energy has its own shortcomings which will not make it possible for these sources to meet the power needs. The theory is backed by the practical experience and it is done by modeling the energy provided by the renewable source. The practicality certainly shows that the consistent power is never provided by the renewable source which means that such power cannot be used at all. The idea is very widespread and is accepted by the experts all over the world. There is another group of experts that have the completely different idea. These theories are backed by the computer simulations which allow these experts to demonstrate that the renewable energy will certainly be used as the main source in the next few decades.

Reduction in demand is the need of the hour so that the baseload demand can be met with ease. The best part of the baseload powering with the renewable energy source is that they can be very energy efficient. In the day the electricity demand is higher and during the night the demand is very low. Altering the structure and the mechanism of the power plants which are currently running it is possible to make sure that the baseline power demand is met. The baseload demand can be easily met with such structures which can run at relatively low capacity during the night. It will also allow the users to overcome the problems which are faced as the energy shortfall.

It is also the time for the experts to create awareness among the users of the energy as well as the other experts that the renewable energy is very much reliable. The fact of the matter is that it will get the same amount of energy from the power generators as the fossil fuel does. The best example of the renewable energy is bioelectricity which is just same as the normal electricity and therefore meets the demands of the people as well as that of the baseline power. The greenhouse and the climate effects are the problems which are related to the idea and negate it completely. With the advancements in technology, it will be possible in the coming years to overcome this problem as well. It has been estimated with the current technology it is possible that the renewable energy sources provide the baseline power for up to 20 hours per day.

Though the output of the energy using the renewable resource varies greatly the average is the same as the other power sources. It has been estimated that about 24% of Denmark’s energy is generated from wind. The other countries which are included in this regard are Portugal and Spain which generated about 14% of the total energy from renewable sources. The renewable resources and the related machinery should be revamped to meet demand and supply fluctuations. It will allow the experts to overcome the issues and study the improvements more closely.

Emera Inc. to Supply 1,000 Megawatts of Renewable Energy to Massachusetts

A new link between Canada and Massachusetts is going to be established based on the connection of clean power sources. Massachusetts is working its way to meet its energy needs with clean energy sources in the bid to adhere to the legislation of greenhouse gas reduction goals.

Back in March this year, Massachusetts invited proposals for the supply of over 9 terawatts of renewable energy each year which encouraged Emera Inc. to get into action and propose a deal to supply 1,000 megawatts of clean power from the Canadian Atlantic region.

The company is working with NB Power and 5 other New Brunswick wind farms to get their supply of required power. Emera set a competitive proposal for Massachusetts which was required in the face of the stiff competition. Starting from January this year, Emera began its search for promising suppliers and all the commercial agreements have been signed by now with the selected suppliers.

The wind farms chosen from New Brunswick area include Silver Brook, Salmon River, Andy’s Pond, Black Spruce, and Colborne. The other 2 farms are in Nova Scotia being Higgins Mountain II and Yorkshire.  The other partners include Nalcor Energy in Newfoundland and Labrador and NB Power who will be supplying hydropower.

Emera has chosen only those suppliers who have a strong experience and proven track records of involving the local community for sustainable development. If all goes well, the 1,000 megawatts of renewable energy will be transmitted to Massachusetts via a 600 km long cable running under the sea. The project has been named Atlantic Link and is set to start from Coleson Cove in Saint John through a planned DC converter station.

The cable is going to terminate at Plymouth which is home to the state’s only nuclear plant. Interestingly, the Pilgrim Nuclear Power Station is set to close down in June 2019 due to poor market conditions and loss of revenues.

The project is also going to benefit Canada and its economy in a big way along with helping Massachusetts to achieve its clean energy targets.  If the project sees the light of the day, it will require setting up of 250 to 300 new wind turbines. Such operations are expected to create around 3,000 jobs for the region and enable it to capitalize on its resources.  The project will require a construction period of 3 years and scheduled to be serviced by December 2022.

Emera’s proposal is one of the many that have reached Massachusetts. But the executives of the company are hopeful of bagging the project as they will have a direct connection with the country without requiring to venture into other US states. The Atlantic Link project can diversify the supply of clean energy if it comes to reality.
