Pagara Masonry Dam was constructed about 94 years from now during the period 1911-1917 in Gwalior (M.P.). After construction, it has breached/damaged and rehabilitated three times.

In hydro electric projects, grouting plays an important role in controlling the seepage and improvement in rock strength for the construction of underground as well as surface structures. The Nathpa Jhakri Hydroelectric Power Station (NJHPS) 1500 MW, the largest hydropower station in India under operation, and downstream Rampur Hydro Electric Project (RHEP) 412 MW, presently under advanced stage of construction, and planned to run in tandem are both located on river Satluj in the Himalayan region.

Small hydropower (SHP) is one of the most common renewable, economic, non-consumptive, non-radioactive, non-polluting and environmentally benign sources of energy. A vast potential of small hydropower is available on canals falls under the range of low head hydropower schemes.

A telemetry SCADA measurement system plays an important role in efficient control and equitable water delivery to the stake holders in the command of Indira Gandhi Nahar project.

Participatory Irrigation Management (PIM) approach is being promoted in India with the aim to improve the performance of public irrigation schemes and ensuring equitable water distribution.

The Renewable Energy Certificate (REC) platform was formally launched by the Central Electricity Regulatory Commission (CERC) on 18 November 2010. This article focuses on the REC mechanism, and the issues and challenges involved for India.

The Central Electricity Regulatory Commission (CERC) announced framework for Renewable Energy Certificates (REC) on 14th January 2010. With the emergence of this new mechanism, a new market segment is expected to be created for renewable energy generation. This paper attempts to give brief background, legal framework and description of this new mechanism. This paper also touches upon the status of RPOs, readiness on part of various states to implement this mechanism.

Key drivers for solar market in India have been country's rapidly rising primary energy and electricity needs, persistent energy deficit situation, and on oil and gas imports. These factors coupled with India's endowment with abundant solar irradiation have made solar particularly attractive to the country's energy strategy.

Moving from 20% to 50% of wind power calls for need for improved wind power forecast and optimal reserve capacities, strong price signal to wind energy generator against deviation from forecast and strong transmission grid. Therefore wind energy developers have to come forward with the developing infrastructure for forecasting wind energy and make power more grid friendly to accomodate more wind energy in the states.

This article will present basic facts on limitations and efficacy of large water storage versus small dams & popularly known as rain water harvesting structures (rwhs) for recharging ground water and suggests serious examination of mother statements about relation of forests and hydrologic elements.
