Never heard of such a project.

Probably the paper fresh, because there are interesting details about other projects.

The top science objective of NGTS is to detect transiting Neptune-sized planets orbiting K dwarfs brighter than 13th V magnitude for which follow-up may be efficiently conducted using
spectrographs like HARPS and later ESPRESSO (planned for 2016).

Manufacturing of HARPS-NEF is ongoing. Installation and first light is planned for mid-2011.

The Next-Generation Transit Survey (NGTS) is a wide-field photometric survey designed to discover transiting exoplanets of Neptune-size and smaller around bright stars (magnitude V<13).

NGTS will employ an array of 12 fully-robotic sm all telescopes operating in the 600-900 nm band, thereby maximizing sensitivity to bright but relatively small host stars (K and early-M spectral type).

NGTS will be sited at ESO-Paranal, home of the ESO’s VLT telescopes, which meets strict requirements for low water vapor and excellent photometric conditions.

SCHEDULE
Summer 2012 on site installation
April 2013 start of first surveys

A new generation of transit surveys such as NGTS will allow the detection of Neptune-sized planets from the ground. NGTS is designed to carry out a wide-field search for transits of Neptune-size planets around bright K and early M stars, reaching 1 mmag precision on stars V < 13 magnitude. This facility is in construction at the ESO Paranal Observatory and the survey will start in 2013. At end of 2017, after five years of operations, about 10% of the southern sky will have been observed. This corresponds to more than 50,000 bright K dwarfs being measured with the required accuracy to detect Neptune-sized transiting planets and about 3500 stars with the required accuracy to detect a transiting super-Earths (radius < 2REarth). By extending the present day ground-based capabilities, NGTS will populate a region of the magnitude-radius diagram for which only very few detections could be made by Kepler (see Fig. 4). While detectable from the ground by NGTS, the radii of these planets will be affected by large errors.

The Next Generation Transit Survey - Prototyping Phase
https://arxiv.org/abs/1611.00691

We present the prototype telescope for the Next Generation Transit Survey, which was built in the UK in 2008/09 and tested on La Palma in the Canary Islands in 2010. The goals for the prototype system were severalfold: to determine the level of systematic noise in an NGTS-like system; demonstrate that we can perform photometry at the (sub) millimagnitude level on transit timescales across a wide field; show that it is possible to detect transiting super-Earth and Neptune-sized exoplanets and prove the technical feasibility of the proposed planet survey. We tested the system for around 100 nights and met each of the goals above. Several key areas for improvement were highlighted during the prototyping phase. They have been subsequently addressed in the final NGTS facility which was recently commissioned at ESO Cerro Paranal, Chile.

In the latest edition of ESO's quarterly journal, The Messenger, an article page 10

« The NGTS becomes operational at Paranal »

A preliminary analysis of the data from the first six months of the full NGTS survey has yielded several dozen candidate planets which are we currently following up. Recent simulations based on the actual performance of NGTS have shown that the full NGTS survey can be expected to detect several super-Earths (planets with a radius less than twice that of the Earth), tens of Neptune-sized planets (2–6 Earth radii), and more than 200 planets with a radius larger than Saturn’s (6–22 Earth radii). NGTS is most sensitive to planets with orbits of less than 20 days
