This paper presents the world's first high voltage utility‐scale battery energy storage system in the multi megawatt range.
Abstract
Purpose
This paper presents the world's first high voltage utility‐scale battery energy storage system in the multi megawatt range.
Design/methodology/approach
The objectives are achieved by the series connection of switching semiconductor devices of the type Insulated Gate Bipolar Transistor (IGBT) and the series and parallel connection of Li‐ion batteries.
Findings
After tests at ABB laboratories, where its performance to specification was confirmed, a first pilot will be installed in the field, in EDF Energy Networks' distribution network in the United Kingdom during 2010 to demonstrate its capability under a variety of network conditions, including operation with nearby wind generation.
Practical implications
This holds the development of a distributed dc breaker, the diagnostics of detecting fault locations as well as fault isolation and the balancing of the batteries.
Originality/value
The paper presents the world's first high voltage utility‐scale battery energy storage system in the multi megawatt range suitable for a number of applications in today's and future transmission and distribution systems.

Abstract
Purpose
Careers have come to dominate contemporary discourse on gendered entrepreneurship. This paper aims to explore entrepreneurial careers as recounted by commercially successful female entrepreneurs to examine how they strategize to construct desirable careers in contexts characterized by underdeveloped markets and weak institutions.
Design/methodology/approach
Using a qualitative research design, data for our inquiry come from publicly available life history accounts of 20 female entrepreneurs appearing on an enterprise focus television show in Nigeria. The authors supplemented the television interview data with archival data in the form of publicly available digital footprints of the entrepreneurs collected from their company websites, magazines, online newspapers featuring these entrepreneurs and their social media pages such as LinkedIn, Wikipedia, Facebook and Instagram.
Findings
The careers of female entrepreneurs operating in context of underdeveloped institution and markets, the authors found, are characterized by four heterogeneous ingrained dispositions and actions reflecting how they got in and got on with their entrepreneurial careers: (1) “Observing and playing business,” (2) traipsing the “path less traveled,” (3) a hook to the “Pierian spring” of entrepreneurship and (4) “Grace under pressure” in decision-making.
Originality/value
The authors contribute to the entrepreneurship literature by providing insight into the lived experiences, agency and careers of commercially successful female entrepreneurs as played out in the form of a contextual practice of “wayfinding” to starting up and managing their own business ventures.
