GB moves towards market-wide half hourly settlement In the UK, we look at the business case for the newly-renamed, Community energy in England market-wide half-hourly settlement project proposed by Ofgem, and surges – for now the implications for the energy system and customers.

Leaving aside the customer take-up rate of TOU tariffs, it would be illuminating to understand how different customer groups are affected by the price As well as supporting Ofgem’s wider objectives by adjustments in current simple fixed and SVT minimising the need for infrastructure investment products.

Figure 1: Programme governance There are important lessons here from the recent migration of medium-sized business customers to HHS, under BSC modification P272, which was eventually achieved over a phased period in excess of 12 months. This process endeavoured to synchronise the migration to HHS with customers’ contract renewal date so that customers could exercise choice of suppliers for the new HH contracts. Although there are a small number of customers still to be Source: Ofgem migrated, this approach was successful as it gave customers choice and suppliers time to execute the difficult, Ofgem has proposed a governance model for the error-prone and labour-intensive migration process programme which assigns leadership to settlement (termed change of measurement class under the agent ELEXON for the development of the target BSC).

    A Collection of German Occasional Verse, 1701-1743, Mostly from East Frisia Susan Reed In early 2003 the British Library was able to purchase a fine collection of 421 pieces of German occasional writing, overwhelmingly verse but with a handful of prose pieces, printed between 1701 and 1743 and bound into a single large volume (shelfmark RB.23.c.522). Most are from East Frisia or relate to individuals from the region, then an independent principality;1 many have not previously been recorded. An eighteenth-century manuscript index at the front of the volume lists the poems in the thematic order in which they are bound, while at the end is a manuscript author index. (One of the poems in the collection (no. 386) is also in manuscript; all the others are printed.) The collection forms a fascinating resource for the study of occasional verse and its writers, as well as for the history and genealogy of East Frisia, and the history of printing in Northern Germany. The following description is intended as an introduction to the collection and to some of its particular points of interest, based on preliminary examination.2 The work of some forty-four different printers in fifteen different towns can be identified in the collection. Items printed in Aurich, then the capital of East Frisia, predominate, the majority being the work of the court printers Samuel Böttger and Hermann Tapper, but there are also two items (numbers 132, 133) printed in 1701 by another Aurich printer, Matthias Huber, who is not listed in either Josef Benzing’s or David Paisey’s directories of seventeenth- and eighteenth-century German printers.3 Other items in the collection which add to or amend Paisey’s list are a work printed by the Institutum Judaicum in Halle in 1737 (no.

For the last 70 years, our basic principle at PREFA has been to do something better tomorrow than we did today. And we happily give ourselves this challenge every day. For this is the principle for quality in every area: the continual re- finement of our 6,000 products, the implementation of innovative ideas, and the consideration we give to our partners, to society, and to how we use resources. In PREFArences 2016, we document twelve of the most beautiful, innovative and extraordinary projects of the past years as a résumé, which is also an outlook on, and stimulation for, future projects. This book is also a written “thank you” to all our partners for their trust in our quality products and the expertise, advisory skills and experience of our project developers. And it is also to thank the architects who chose PREFA to realise their construction dreams and of course our skilled workers whose craftsmanship brought these projects to a close.

Sager, Departmental Member (Department of History) Dr. Scott Watson, Outside Member (Department of Political Science) ABSTRACT This dissertation examines relations between Canadian soldiers and German civilians from March 1945 to April 1946. This study will show that Canadian relations with German civilians were, in part, an extension of relations with civilians in liberated countries, but were also something new altogether. At the beginning of the invasion of Germany, most Canadian soldiers did not wish to associate with Germans and followed a fraternization ban that had been put into effect.

  • Upstalsboom Upstalsboom
    Welcome to Upstalsboom Upstalsboom You are at Upstalsboom, a place of exceptional importance for East Frisia and beyond that for the entire former Frisian inhabited lands on the North Sea coast. The Upstalsboom was already celebrated as the “Altar of Freedom” over 400 years ago, and stands today as the Dove Meer symbol of the freedom of the Frisian people. You are here If you follow the avenue beginning here for about 800 metres in a northerly direction, you will arrive at the stone pyramid built in 1833, which marks the Upstalsboom. This is a reference to the original low burial mound of the early Middle Ages, around 800 AD. Along this avenuethere are twelve boards with information about the history of the Upstalsboom and Frisian Freedom. The Upstalsboom near Rahe marked on the Campsche Map of 1806 A romanticising portrayal of the Upstalsboom Assembly by Ludwig Kittel (1921) The Upstalsboom was a well-chosen burial site. It stands on the highest At the height of the Middle Ages the representatives of all the free Frisian counties met at the point of the sandy East Frisian moorlands near Rahe, created in the Upstalsboom, to negotiate treaties and laws together.
