RWE Commissions the 200-MW Stoneridge Solar Project in Texas

LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

Northeast Releases Draft Model Rule for Regional Greenhouse Gas Initiative

LCG, March 24, 2006--The Regional Greenhouse Gas Initiative (RGGI) took another step forward yesterday with the release of the draft model rule, which sets forth for public comment the specific rules upon which to establish within each participating state a cap-and-trade program designed to reduce greenhouse gases and related concerns of global warming. The release of the model is a key action included in the Memorandum of Understanding (MOU) signed in December 2005 by the governors of Connecticut, Delaware, Maine, New Hampshire, New Jersey, New York and Vermont (the "Signatory States").

Public comments on the draft model rule can be submitted until May 22. The final model rule is scheduled to be released in July 2006, and the launch date for the trading program is January 1, 2009.

The draft model rule targets reducing carbon dioxide (CO2) emissions from electric generators with capacities equal to or greater than 25 MW that burn primarily fossil fuels. Like the existing SO2 emission allowance market, if a company does not have sufficient CO2 allowances to cover CO2 emissions from its generators, it must either reduce annual emissions or purchase allowances from sources able to keep their emissions below their prescribed cap. Generators that sell less than 10% of the electricity they generate to the grid will be exempt.

The program includes allowance offsets to sponsors of approved CO2 emission offset projects, such as landfill gas capture and combustion, sulfur hexaflouride capture and recycling, converting non-forested to forested land, and projects to reduce fugitive methane emissions from natural gas transmission and distribution. Offsets may only be used to cover a small portion of CO2 emissions, e.g., initially up to 3.3% of CO2 emissions.

For offset projects located in Signatory States, allowances will be awarded on the basis of one allowance for each CO2-equivalent ton. However, for offset projects located outside the Signatory States, allowances will be awarded on the basis of one allowance for every two CO2-equivalent tons. If the spot price of CO2 emissions equals or exceeds certain triggers, then offset allowances may be awarded outside of the United States.

Each Signatory State will receive a specific allocation of CO2 allowances, and each state may then issue the allowances. The model rule provides for each state to allocate 25% of the allowances for a consumer or strategic energy purpose, such as the development of non-carbon emitting energy technologies. For the years 2009 through 2014, each state's CO2 budget will remain unchanged. The quantity of allowances will be stable from 2009 through the beginning of 2015, with a decline through 2018 that is designed to achieve a 10% reduction in CO2 emissions.

Massachusetts and Rhode Island had initially contributed to the development of RGGI but have elected not to sign the MOU. The MOU allows for these two states to opt back in prior to January 1, 2008 and encourages other states to join the program
