The consultation period ended on Wednesday 25 August 2021 at 17:00.&#xA0;<\/p>\n<p>The methodology instructs Elexon to:<\/p>\n<ul>\n<li>Divide the BSC Year into Electricity Forward Agreement (EFA) Days (23.00 &#x2013; 23.00), and group the EFA Days<br>\nwithin each week into blocks of consecutive Working and Non-Working Days. This divides the BSC Year into<br>\ncirca 104 blocks of consecutive EFA Days, with each week having a block with five Working Days and a block<br>\nwith two non-Working Days (except where there are Bank Holidays).<\/li>\n<li>Split each of these blocks into six time bands, corresponding to the six four-hour blocks within the EFA Day.<br>\nEach time band, within each block of days, is a LP, so there will be circa 624 LPs within the Reference Year.<\/li>\n<li>&#xA0;SSPs are then randomly selected from each LP, with one SP taken from EFA Block 1, one from EFA Block 2,<br>\nbut two SPs from each of the remaining four EFA Blocks. This means the total number of SSPs in the<br>\nReference Year will be circa 1040.<\/li>\n<li>The sample (1,040 Settlement Periods from 17,520) will be large enough to be statistically representative, and increasing it further would require a change to the TLFA contract.<\/li>\n<\/ul>\n<p>More details can be found in the consultation document on this page.<\/p>\n<h2 id=\"further-information\">Further information<\/h2>\n<p>For questions, <a href=\"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/about\/elexon-key-contacts\/bsc-service-desk\/\">please contact the BSC Service Desk<\/a><\/p>\n\n\t<\/div>\n\n\n\n","s3_url":""},"_links":{"self":[{"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/consultation\/173210","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/consultation"}],"about":[{"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/types\/consultation"}],"version-history":[{"count":1,"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/consultation\/173210\/revisions"}],"predecessor-version":[{"id":186142,"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/consultation\/173210\/revisions\/186142"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/media\/165690"}],"wp:attachment":[{"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/media?parent=173210"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/elexon-beta.elexonhostings.co.uk\/bsc\/wp-json\/wp\/v2\/tags?post=173210"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
