Scottish hotel plugs in to battery storage trial

Gyle Edinburgh Park Premier Inn

A lithium-ion battery storage system has been ‘booked in’ to a hotel in Scotland as part of an energy efficiency trial project.

The Gyle Premier Inn at Edinburgh Park, owned by brewing giant Whitbread, said the 100kW battery has the capacity to run the hotel— “including powering meals cooked” at its bar and grill— for up to three hours daily.

The battery functions by drawing power from the National Grid during off-peak periods and takes two hours to fully charge.

UK’s Pivot Power unveils 2GW battery network plan

Plans have been unveiled to build a 2GW network of grid-scale batteries and rapid electric vehicle (EV) charging stations across England and Wales.

UK firm Pivot Power said the GBP1.6 billion ($2.1bn) programme will see 45 sites developed— “installing grid-scale 50-megawatt batteries at electricity sub-stations connected directly to the extra-high-voltage transmission system”.

NZ opts for Tesla as battery battle hots up Down Under

Tesla is to supply New Zealand with the same battery tech it has installed in South Australia as an antipodean battle of the batteries hots up.

New Zealand’s majority state-owned electricity generator, Mercury NZ, has selected Tesla to provide the battery for what it said will be the country’s “first” national grid connected battery trial.

50MW Li-Ion storage boost for UK

Two grid-scale projects totalling 50MW of new energy storage capacity have been connected to the grid in the UK.

The US-European partners behind the lithium-ion projects said the commissioning represented the “largest portfolio of utility-scale battery energy storage systems connected to the UK grid”.

Changes to UK utility scale energy storage tender process

Changes to UK utility scale energy storage tender process

UK utility National Grid is opening up the tender process to allow smaller companies and non-traditional energy storage methods to compete in the grid-scale UK market.

The company is aiming to simplify its suite of balancing services rather than simply tendering for more individual services targeting specific needs, such as Enhanced Frequency Response (EFR).

Last year the company successfully tendered 201MW of EFR in eight projects totalling £65.95m (with an average price of £9.44/MW of EFR/h) to maintain the grid frequency at 50Hz.

This year the company is re-writing the process in a bid to

group together balancing services with similar requirements and make the process of energy distribution more flexible.

The three initial groups will include Frequency Response, Reserve Energy and Standby & Margin categories, although others may be added.

So for example, EFR and firm frequency response (FFR) dynamic and static will be in the general frequency response category; whereas reserve services and demand turn-up will be grouped in the reserve energy section along with STOR runway.

Work on the new proposal is ongoing, with National Grid planning to announce more details in its Electricity Future Operability Strategy document at the end of March.

The proposals are likely to involve a gradual roll out rather than a sudden step change of the policy.

Stewart Larque, head of Regional Media at National Grid, told BBB: “The intention is exactly the opposite to restricting the opportunities to big players – we want to remove complexity and barriers to smaller players and non-traditional technology types, encouraging greater competition for balancing services.

“The aim is to provide more clarity to all potential providers through having fewer but ‘deeper’ services where providers may tender in specific variables such as speed of response or duration. This will allow all assets, including storage, a better route to market than the current suite of products.

“So, in summary, parties providing response in enhanced timescales will still have a route to market but it will be through those deeper balancing service marketplaces rather than ad hoc periodic tender events.”

UK gets first MW grid-scale lithium-ion energy storage system

Great Britain is to test its first battery system to provide grid-frequency after a partnership between energy utility firm National Grid and UK based Renewable Energy Systems (RES).

The 20MW battery storage system will provide a dynamic frequency response service with a second of a deviation, either higher or lower than 50Hz, being detected.

UK’s National Grid: Battery energy storage too costly for balancing services

Thu, 07/10/2014 - 10:02 -- Editor
National grid

Battery energy storage costs need to fall by as much as 99% to be competitive with other grid balancing technologies, according to UK transmission system operator National Grid.

In a report published on 10 July, Future Energy Scenarios 2014, National Grid explored the number of years taken to recover the cost of sodium sulphur and lithium-ion batteries through revenue from individual reserve services – Short Term Operating Reserve (STOR) and Fast Reserve - and the decrease in total plant costs that would be necessary in order to recover costs.

Smart grid trialled in Massachusetts

Fri, 01/25/2013 - 17:36 -- Ruth Williams

A smart grid pilot project is to be implemented in Worcester, Massachusetts, US by the National Grid to demonstrate the uses of available technology to improve energy efficiency.

National Grid

Its aim is to provide energy customers with choice and control over the energy they use to empower customers to save energy, while increasing electric service reliability and improving response to power outages.

National Grid has amassed a team of experts to work on the project to construct and deliver an end-to-end smart grid pilot including smart meters, advanced communications technologies, in-home energy management tools, devices for electric system automation, as well as customer outreach and education, project management, integration and evaluation.

Unlike other smart grid trials in the US, customer engagement is key. Customers choose their level of involvement and can receive information about their energy use via the website and downloadable app. Pricing options will be available so customers can save energy and money at different times of day.

National Grid will also be researching the option of full integration of renewable energy sources, installing EV charging stations and connecting energy storage to existing renewable projects.
